How do you find a equation from a table

Answers

First you need to identify the type of equation in the table, then you can set up the correspondent equation or system of equations to find your equation.

How to find an equation from a table?

To find an equation from a table, you will need to identify the pattern or relationship between the given inputs and outputs (so the first thing you need to do, is identify which type of equation is represented by the table)

There are different methods depending on the type of relationship and the data provided. Here are a few common approaches:

Linear Relationship (y = ax + b)

If the table data suggests a linear relationship between the inputs (x-values) and outputs (y-values), you can use the method of finding the equation of a straight line. This can be done by calculating the slope (m) and the y-intercept (b) using two data points from the table.

Quadratic Relationship (y = ax² + bx + c)

If the table data suggests a quadratic relationship, meaning the outputs change according to a quadratic function of the inputs, you can use the method of finding the equation of a quadratic function. This involves using three data points from the table and solving a system of equations to determine the coefficients of the quadratic equation.

Exponential Relationship (y = A*bˣ)

If the table data suggests an exponential relationship, where the outputs change exponentially with respect to the inputs, you can use the method of finding the equation of an exponential function. This involves determining the base and exponent of the exponential function by examining the ratios between the outputs.

Please notice that these are only 3 types of equations, but there are a lot more, like logarithmic functions, trigonometric functions, cubic functions.

And each one will have a different way of setting up equations to find the equation represented in the table.

A random sample of size n=200 is to be taken from a uniform population with α=24 and β=48. Based on the central limit theorem, what is the probability that the mean of the sample will be less than 35?

Answers

The probability that the mean of the sample will be less than 35 is approximately 0.0205, or 2.05%.

To solve this problem, we'll use the central limit theorem, which states that for a large enough sample size, the distribution of sample means approximates a normal distribution, regardless of the shape of the population distribution.

Given that the population follows a uniform distribution with α = 24 and β = 48, we know that the mean (μ) of the population is given by the formula:

μ = (α + β) / 2

Substituting the values, we have:

μ = (24 + 48) / 2 = 72 / 2 = 36

The standard deviation (σ) of the population is given by the formula:

σ = (β - α) / √12

Substituting the values, we have:

σ = (48 - 24) / √12 = 24 / √12 = 24 / 3.464 = 6.928

According to the central limit theorem, the distribution of sample means follows a normal distribution with a mean equal to the population mean (μ) and a standard deviation equal to the population standard deviation (σ) divided by the square root of the sample size (n). Therefore:

μ_s = μ = 36

σ_s = σ / √n = 6.928 / √200 ≈ 0.490

To find the probability that the mean of the sample will be less than 35, we need to find the area under the normal distribution curve to the left of 35. We'll use a standard normal distribution with a mean of 0 and a standard deviation of 1, and then transform it using the mean and standard deviation of the sample distribution.

Let's calculate the z-score for 35:

z = (x - μ_s) / σ_s = (35 - 36) / 0.490 ≈ -2.041

Using a standard normal distribution table or a calculator, we can find the probability corresponding to a z-score of -2.041. The probability that the mean of the sample will be less than 35 is approximately 0.0205, or 2.05%.

find the general antiderivative of n(x)=x8 5x4x5.

Answers

The general antiderivative of n(x) = x⁸ + 5x⁴ + x⁵ is N(x) = (1/9)x⁹ + (1/5)x⁵ + (1/6)x⁶ + C.

To find the antiderivative of n(x) = x⁸ + 5x⁴ + x⁵, we apply the power rule for integration, which states that ∫x^n dx = (xⁿ⁺¹)/(n+1) + C, where C is the constant of integration.

1. For the first term, x⁸, integrate using the power rule: ∫x⁸ dx = (1/9)x⁹ + C₁.
2. For the second term, 5x⁴, integrate: ∫5x⁴ dx = 5(1/5)x⁵ + C₂ = x⁵ + C₂.
3. For the third term, x⁵, integrate: ∫x⁵ dx = (1/6)x⁶ + C₃.

Now, add the results of each integration and combine the constants: N(x) = (1/9)x⁹ + x⁵ + (1/6)x⁶ + (C₁ + C₂ + C₃). Since the constants are arbitrary, we can represent them as a single constant, C: N(x) = (1/9)x⁹ + (1/5)x⁵ + (1/6)x⁶ + C.

Suppose that when your friend was​ born, your​ friend's parents deposited ​$5000 in an account paying ​4. 7% interest compounded. What will the account balance be after 18 years?

Answers

After 18 years, the account balance will be calculated based on a $5000 deposit with a 4.7% interest compounded.

To calculate the account balance after 18 years, we will use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = Final account balance
P = Principal amount (initial deposit)
r = Annual interest rate (in decimal form)
n = Number of times interest is compounded per year
t = Number of years
In this case, the principal amount is $5000, the annual interest rate is 4.7% (or 0.047 as a decimal), the interest is compounded annually (n = 1), and the time period is 18 years (t = 18).
Using the formula, we can calculate the account balance:
A = $5000(1 + 0.047/1)^(1*18)
= $5000(1 + 0.047)^18
= $5000(1.047)^18
≈ $5000 * 1.990
≈ $9949.92
Therefore, after 18 years, the account balance will be approximately $9949.92.

Answers

To determine whether the matrix is in echelon form, reduced echelon form, or neither, let's first write the given matrix clearly:

[1 0 5 4]
[0 1 -5 -3]
[0 0 0 0]
[0 0 0 0]

Now, let's analyze its form:

a) Echelon form requires:
1. All nonzero rows are above any rows of all zeros.
2. The leading coefficient (pivot) of a nonzero row is always to the right of the pivot of the row above it.

This matrix satisfies both conditions, so it is in echelon form.

b) Reduced echelon form requires:
1. The matrix is in echelon form.
2. The pivot in each nonzero row is 1.
3. Each pivot is the only nonzero entry in its column.

This matrix fulfills the first two conditions, but the third condition is not met due to the presence of '5' in the first row and the same column as the pivot '1' in the second row.

Therefore, the matrix is in echelon form (option b) but not in reduced echelon form.

use part one of the fundamental theorem of calculus to find the derivative of the function. f(x) = 0 1 sec(7t) dt x hint: 0 x 1 sec(7t) dt = − x 0 1 sec(7t) dt

Answers

The derivative of the function f(x) = 0 to x sec(7t) dt is sec^2(7x) * tan(7x).

The derivative of the function f(x) = 0 to x sec(7t) dt is sec(7x).

To see why, we use part one of the fundamental theorem of calculus, which states that if F(x) is an antiderivative of f(x), then the definite integral from a to b of f(x) dx is F(b) - F(a).

Here, we have f(x) = sec(7t), and we know that an antiderivative of sec(7t) is ln|sec(7t) + tan(7t)| + C, where C is an arbitrary constant of integration.

So, using the fundamental theorem of calculus, we have:

f(x) = 0 to x sec(7t) dt = ln|sec(7x) + tan(7x)| + C

Now, we can take the derivative of both sides with respect to x, using the chain rule on the right-hand side:

f'(x) = d/dx [ln|sec(7x) + tan(7x)| + C] = sec(7x) * d/dx [sec(7x) + tan(7x)] = sec(7x) * sec(7x) * tan(7x) = sec^2(7x) * tan(7x)

Therefore, the derivative of the function f(x) = 0 to x sec(7t) dt is sec^2(7x) * tan(7x).

A system of equations is given.

Equation 1: 5x − 2y = 10
Equation 2: 4x − 3y = 15

Explain how to eliminate x in the system of equations.

Source
StylesFormatFontSize

Answers

Answer:

To eliminate x, you need a positive coefficient in front of x for one equation and its negative counterpart in front of the other equation as a positive number plus its negative opposite equals 0 (e.g., -4 + 4 = 0 and -80 + 80 = 0)

Step 1:  Therefore, we can eliminate x by first determining the least common multiple (LCM) between 5 and 4.  We know that 5 * 4 = 20 and 4 * 5, so the LCM between 5 and 4 is 20.

Step 2:  In order to have 20 as coefficient for x in one equation and -20 for x as a coefficient in the other equation, we can multiply the entire first equation by 4 and the entire second equation by -5:

Equation 1 multiplied by 4:  4 * (5x - 2y = 10) = 20x - 8y = 40

Equation 2 multiplied by -5:  -5* (4x - 3y = 15) = -20x + 15y = -75

Step 3:  Adding the two equations shows that the xs cancel as 20x - 20x = 0, leaving us with 15y - 8y = 40 - 75, which simplifies to 7y = -35

Answer: See below.

Step-by-step explanation:

       First, we are already given these equations in standard form.

5x − 2y = 10

4x − 3y = 15

       Next, we need to make the coefficients of the x variables opposites (as in 5 and -5, etc), since we want to eliminate the x's. To do this, we will find a common multiple (here, the Lowest Common Multiplb is 20). Then, we will multiply every term by the number that makes the coefficient of x our common multiple.

       We will make the first equation with a coefficient of 20 for the x and the second with a coefficient of -20 for the x.

       See this visually below.

5x − 2y = 10 ➜ 4(5x) − 4(2y) = 4(10) ➜ 20x - 8y = 40

4x − 3y = 15 ➜ -5(4x) − -5(3y) = -5(15) ➜ -20x + 15y = -75

       Lastly, add these two equations together. The x's are eliminated. This also will let us solve for y.

      20x - 8y = 40

+   -20x + 15y = -75

an item is selected randomly from a collection labeled {1,2,...,n}. Denote its label by X. Now select an integer Y uniformly at random from {1,2,...X}. Find :
a) E(Y)
b) E(Y^(2))
c) standard deviation of Y
d) P(X+Y=2)

Answers

(a) The expected value of Y is :

E(Y) = (n+1)/3

(b) The value of E(Y^2) = (2n^2+5n+1)/6

(c) The variance of Y = (2n^2+5n+1)/6 - [(n+1)/3]^2

(d) P(X+Y=2) = 1/n

a) To find the expected value of Y, we use the law of total probability:

E(Y) = ∑ P(X=k)E(Y|X=k) for k=1 to n

Since Y is uniformly distributed on {1,2,...,X}, we have E(Y|X=k) = (k+1)/2.

Therefore,

E(Y) = ∑ P(X=k)(k+1)/2 for k=1 to n

To find P(X=k), note that X can take on any value from 1 to n with equal probability, so P(X=k) = 1/n for k=1 to n. Thus,

E(Y) = ∑ (k+1)/2n for k=1 to n

E(Y) = [1/2n ∑ k] + [1/2n ∑ 1] for k=1 to n

E(Y) = [1/2n (n(n+1)/2)] + [1/2n n]

E(Y) = (n+1)/3

b) To find E(Y^2), we use the law of total probability again:

E(Y^2) = ∑ P(X=k)E(Y^2|X=k) for k=1 to n

Since Y is uniformly distributed on {1,2,...,X}, we have E(Y^2|X=k) = (k^2+3k+2)/6. Therefore,

E(Y^2) = ∑ P(X=k)(k^2+3k+2)/6 for k=1 to n

Using the same values of P(X=k) as before, we get:

E(Y^2) = ∑ (k^2+3k+2)/6n for k=1 to n

E(Y^2) = [1/6n ∑ k^2] + [1/2n ∑ k] + [1/6n ∑ 1] for k=1 to n

E(Y^2) = [1/6n (n(n+1)(2n+1)/6)] + [1/2n (n(n+1)/2)] + [1/6n n]

E(Y^2) = (2n^2+5n+1)/6

c) The variance of Y is given by Var(Y) = E(Y^2) - [E(Y)]^2. Therefore,

Var(Y) = (2n^2+5n+1)/6 - [(n+1)/3]^2

d) To find P(X+Y=2), we note that X+Y=2 if and only if X=1 and Y=1. Since X is uniformly distributed on {1,2,...,n}, we have P(X=1) = 1/n. Since Y is uniformly distributed on {1,2,...,X}, we have P(Y=1|X=1) = 1. Therefore,

P(X+Y=2) = P(X=1)P(Y=1|X=1) = 1/n

Rewrite the product as a sum or difference. 16 sin(28x) sin(11x) Rewrite the product as a sum or difference. sin(-x) sin(9x)

Answers

The product as a sum or difference is:

1) 16 sin(28x) sin(11x) = 8[cos(17x) - cos(39x)]
2) sin(-x) sin(9x) = ([tex]\frac{1}{2}[/tex])[cos(-10x) - cos(8x)]

1) 16 sin(28x) sin(11x)
We can use the Product-to-Sum identity: sin(A)sin(B) = (1/2)[cos(A-B) - cos(A+B)]
So, 16 sin(28x) sin(11x) can be rewritten as:
8[cos(28x - 11x) - cos(28x + 11x)] = 8[cos(17x) - cos(39x)]
2) sin(-x) sin(9x)
Again, we use the Product-to-Sum identity: sin(A)sin(B) = ([tex]\frac{1}{2}[/tex])[cos(A-B) - cos(A+B)]
So, sin(-x) sin(9x) can be rewritten as:

find the area enclosed by the given parametric curve and the y-axis. x = t2 − 3t, y = t

Answers

The area enclosed by the given parametric curve and the y-axis is -4.5 square units.

To find the area enclosed by the given parametric curve and the y-axis, we can use the formula for calculating the area bounded by a parametric curve:

A = ∫ |x(t) dy/dt| dt

In this case, the parametric equations are:

x = t^2 - 3t

y = t

To calculate the derivative dy/dt, we differentiate y = t with respect to t:

dy/dt = 1

Now we can substitute the values into the area formula:

A = ∫ |(t^2 - 3t)(1)| dt

A = ∫ |t^2 - 3t| dt

To calculate the integral, we need to split it into two parts based on the absolute value:

A = ∫ (t^2 - 3t) dt (for t ≥ 0)

A = ∫ -(t^2 - 3t) dt (for t < 0)

Evaluating the integrals:

For t ≥ 0:

A = (1/3)t^3 - (3/2)t^2 + C1

For t < 0:

A = -(1/3)t^3 + (3/2)t^2 + C2

To find the specific bounds of integration, we need to determine the range of t that corresponds to the area enclosed by the curve and the y-axis. This can be done by finding the points where the curve intersects the y-axis.

Setting x = 0, we have:

0 = t^2 - 3t

t(t - 3) = 0

t = 0 or t = 3

Therefore, the bounds of integration will be from t = 0 to t = 3.

Substituting these bounds into the area formula, we get:

A = [(1/3)(3)^3 - (3/2)(3)^2] - [(1/3)(0)^3 - (3/2)(0)^2]

A = [(1/3)(27) - (3/2)(9)] - 0

A = 9 - 13.5

A = -4.5

The area enclosed by the given parametric curve and the y-axis is -4.5 square units. Note that the negative sign indicates that the curve is below the x-axis for part of the interval.

A number p, when rounded to 3 decimal places it is equal to 0.079
Find the upper and lower bound of p

Answers

To find the upper and lower bounds of p, we need to consider the range of values that could be rounded to 0.079 when rounded to 3 decimal places.

The midpoint between 0.0785 and 0.0795 is (0.0785 + 0.0795) / 2 = 0.079. Any value between 0.0785 and 0.0795 would round to 0.079 when rounded to 3 decimal places.

Therefore, the lower bound of p is 0.0785 and the upper bound of p is 0.0795.

The given integral can be expressed in terms of simpler integrals as:

[tex]\int (−3x^2 + 5x + 6x cos(x)) dx = -x^3 + (5/2)x^2 + 6x sin(x) + 6 cos(x) + C[/tex](

To express the given integral in terms of simpler integrals, we can use the properties of the indefinite integral, including the linearity property and integration by parts.

We can first break down the integrand using linearity:

[tex]\int (−3x^2 + 5x + 6x cos(x)) dx = \int (-3x^2) dx + \int (5x) dx + \int (6x cos(x)) dx[/tex]

Now, we can integrate each term separately:

[tex]\int (-3x^2) dx = -x^3 + C1[/tex] (where C1 is the constant of integration)

[tex]\int (5x) dx = (5/2)x^2 + C2[/tex] (where C2 is another constant of integration)

To integrate ∫(6x cos(x)) dx, we can use integration by parts with u = 6x and dv = cos(x) dx:

∫(6x cos(x)) dx = 6x sin(x) - ∫(6 sin(x)) dx

= 6x sin(x) + 6 cos(x) + C3 (where C3 is another constant of integration)

Putting everything together, we have:

[tex]\int (−3x^2 + 5x + 6x cos(x)) dx = -x^3 + C1 + (5/2)x^2 + C2 + 6x sin(x) + 6 cos(x) + C3[/tex]

So the given integral can be expressed in terms of simpler integrals as:

[tex]\int (−3x^2 + 5x + 6x cos(x)) dx = -x^3 + (5/2)x^2 + 6x sin(x) + 6 cos(x) + C[/tex](where C = C1 + C2 + C3 is the overall constant of integration)

d. All three people in a group of three randomly-chosen people who buy movie tickets also buy popcorn

Answers

The result "100" in the simulation simulates that exactly one person in a group of three randomly chosen people who buy movie tickets also buys popcorn.


In the simulation, Lindsey generated three random numbers for each trial to represent the behavior of three people at the movie theater. According to the given rules, any number from 1 through 6 represents a person who buys a movie ticket and popcorn, while any number from 7 through 9 or 0 represents a person who buys only a movie ticket.

To estimate the probability that exactly two in a group of three people selected randomly at a movie theater will buy both a movie ticket and popcorn, Lindsey needed to run multiple trials of the simulation. In one of the trials, the result was "100", which means that one of the three randomly-chosen people bought both a movie ticket and popcorn, while the other two only bought a movie ticket.

Therefore, the result "100" in the simulation simulates that exactly one person in a group of three randomly-chosen people who buy movie tickets also buys popcorn.


Based on the simulation results, Lindsey can estimate the probability of exactly two people buying both a movie ticket and popcorn out of a group of three randomly chosen people who buy movie tickets at the theater. By analyzing all 30 trials of the simulation, Lindsey can calculate the relative frequency of this event and use it as an estimate of the probability.

If f(x) is a polynomial, then is f(x^2) a polynomial?

Answers

If `f(x)` is a polynomial, then `f(x²)` is also a polynomial. Polynomials are mathematical expressions that consist of variables and coefficients with only the operations of addition, subtraction, multiplication, and non-negative integer exponents. We can prove this statement using the definition of a polynomial. Definition of a polynomial polynomial is an expression that can be written as follows:$$f(x)= a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+\cdot\cdot\cdot +a_1x+a_0$$where `a0, a1, …, an` are constants, and `n` is a non-negative integer. This definition of the polynomial can be used to show that `f(x²)` is also a polynomial. Using the definition of a polynomial, we can write:$$f(x²)= a_n(x²)^n+a_{n-1}(x²)^{n-1}+a_{n-2}(x²)^{n-2}+\cdot\cdot\cdot +a_1(x²)+a_0$$Simplifying the terms of the expression, we get:$$f(x²)= a_nx^{2n}+a_{n-1}x^{2(n-1)}+a_{n-2}x^{2(n-2)}+\cdot\cdot\cdot +a_1x^2+a_0$$This proves that `f(x²)` is also a polynomial. Therefore, if `f(x)` is a polynomial, then `f(x²)` is also a polynomial.

Yes, if f(x) is a polynomial, then f(x²) is also a polynomial.

A polynomial is a mathematical expression consisting of variables, coefficients, and non-negative integer exponents. It can include addition, subtraction, and multiplication operations. The terms in a polynomial can be in the form of axⁿ, where a is the coefficient, x is the variable, and n is a non-negative integer exponent.

When we substitute x² into f(x), each occurrence of x in the polynomial f(x) is replaced by x². Since x² is still a variable with a non-negative integer exponent, the resulting expression f(x²) remains a polynomial. The coefficients and exponents may change, but the essential structure of a polynomial is preserved.

Therefore, if f(x) is a polynomial, then f(x²) is also a polynomial.

let d={4,7,9}, e={4,6,7,8} and f={3,5,6,7,9}. list the elements in the set (d ∪ e) ∩ F
(d ∪ e) ∩ F = ___
(Use a comma to separate answers as needed. List the element)

Answers

the right answer on this question is 7,9

Thus, list the elements in the set (d ∪ e) ∩ F is {4, 6, 7, 9}.



To find the elements in the set (d ∪ e) ∩ F, we first need to determine what the union of d and e is.

Given that:

d={4,7,9}, e={4,6,7,8} and f={3,5,6,7,9}.

The union of two sets, denoted by the symbol ∪, is the set of all elements that are in either one or both of the sets.

So, in this case, d ∪ e would be the set {4, 6, 7, 8, 9}.

Next, we need to find the intersection of the set {4, 6, 7, 8, 9} and f.

The intersection of two sets, denoted by the symbol ∩, is the set of all elements that are in both sets.

So, the elements in the set (d ∪ e) ∩ F would be the elements that are common to both {4, 6, 7, 8, 9} and {3, 5, 6, 7, 9}. These elements are 4, 6, 7, and 9.
