Computer the lower Riemann sum for the given function f(x) = 4 - x^3 over the interval x E [0,1] with respect to the partition P = [0, 1/2, 3/4, 1]
Answers
Answer:
[tex]\dfrac{917}{256}=3.58203125[/tex]
Step-by-step explanation:
The Riemann sum is a method by which we can approximate the area under a curve using a series of rectangles.
The Lower Riemann Sum uses the minimum height of the rectangle on each subinterval.
As the Lower Riemann Sum is entirely below the curve, it is an underestimation of the area under the curve.
The number of partitions is the number of rectangles used.
Partitions can be of equal length or not of equal length.
Given:
Function: f(x) = 4 - x³Interval: [0, 1]Partition, P = [0, 1/2, 3/4, 1]The given partition divides the interval [0, 1] into 3 subintervals:
[0, 1/2], [1/2, 3/4] and [3/4, 1]To calculate the areas of the rectangles, multiply the width of each rectangle by its height.
The width is the difference between the x-values of each subinterval.
The height is the minimum value of the function across the subinterval. For the given function, this is the value of the function for the right side of the subinterval.
First rectangle [0, 1/2]:
[tex]\begin{aligned}\implies \left(\dfrac{1}{2}-0\right) \cdot f\left(\dfrac{1}{2}\right)&=\dfrac{1}{2} \cdot \left(4-\left(\dfrac{1}{2}\right)^3\right)\\\\&=\dfrac{1}{2} \cdot \dfrac{31}{8}\\\\&=\dfrac{31}{16}\end{aligned}[/tex]
Second rectangle [1/2, 3/4]:
[tex]\begin{aligned}\implies \left(\dfrac{3}{4}-\dfrac{1}{2}\right) \cdot f\left(\dfrac{3}{4}\right)&=\dfrac{1}{4} \cdot \left(4-\left(\dfrac{3}{4}\right)^3\right)\\\\&=\dfrac{1}{4} \cdot \dfrac{229}{64}\\\\&=\dfrac{229}{256}\end{aligned}[/tex]
Third rectangle [3/4, 1]:
[tex]\begin{aligned}\implies \left(1-\dfrac{3}{4}\right) \cdot f\left(1\right)&=\dfrac{1}{4} \cdot \left(4-\left(1\right)^3\right)\\\\&=\dfrac{1}{4} \cdot 3\\\\&=\dfrac{3}{4}\end{aligned}[/tex]
Therefore, the Lower Reimann Sum for the given function over the given interval and partitions is the sum of the area of the rectangles:
[tex]\implies \dfrac{31}{16}+\dfrac{229}{256}+\dfrac{3}{4}=\dfrac{917}{256}=3.58203125[/tex]

differentiate f(x) =5√x using first principle
Answers
Answer: To differentiate a function using the first principle, we first need to know the function and it's original value. Given that the function is f(x) = 5√x .
The first principle of differentiation states that the derivative of a function f(x) at a point x is approximately equal to the change in f(x) for an infinitesimal change in x. We can use this principle to find the derivative of a function f(x) at a point x by calculating the limit of the ratio (f(x+dx)-f(x))/dx as dx approaches zero.
To differentiate f(x) = 5√x with respect to x using the first principle, we take the following steps:
Find the change in f(x) as x changes by dx, which is f(x + dx) - f(x)
Divide that change by dx to find the slope of the function at that point
Take the limit of that slope as dx approaches zero
So:
f(x + dx) = 5√(x + dx)
f(x) = 5√x
change in f(x) = f(x + dx) - f(x) = 5√(x + dx) - 5√x
slope = change in f(x) / dx
= (5√(x + dx) - 5√x) / dx
The limit as dx approaches zero is the derivative of the function,
lim (dx->0) [(5√(x + dx) - 5√x) / dx]
= lim (dx->0) [(5(x+dx)^1/2 - 5x^1/2) / dx]
= 5 * lim (dx->0) [(x+dx)^1/2 - x^1/2] / dx
= 5 * (1/2)x^(-1/2)
So the derivative of the function f(x) = 5√x is (5/2)x^(-1/2)
This is the slope of the function at a point x, which is the rate of change of the function at that point x.

How to solve a quadratic-like equation by factoring
In this problem we find a quadratic-like equation of the form a · x²ⁿ + b · xⁿ + c = 0, where a, b, c are real coefficients and whose roots must be found. This can be done by completing the square and clear variable x. First, write the polynomial:
x⁴ + 9 · x² - 10 = 0
Second, use the following substitution: u = x²
u² + 9 · u - 10 = 0
Third, complete the square:
u² + 9 · u + 81 / 4 = 10 + 81 / 4
u² + 9 · u + 81 / 4 = 121 / 4
Fourth, factor the expression and clear variable u:
(u + 9 / 2)² = 121 / 4
u + 9 / 2 = ± 11 / 2
u = - 9 / 2 ± 11 / 2
Fifth, reverse the substitution and clear variable x:
x² = - 9 / 2 ± 11 / 2
x = ±√(- 9 / 2 ± 11 / 2)

Answers
The length of the isosceles trapezoid height CE is 14 meters.
How do you calculate the length?To find the length of the height CE of the isosceles trapezoid, we can use the Pythagorean theorem.
The isosceles trapezoid CE is the hypotenuse of the right triangle formed by height CE and distance AC. CE is also the height of the trapezoid. Let the length of CE be 'x'
The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle (CE) is equal to the sum of the squares of the lengths of the other two sides (AC and CE).
x² = AC² + CE²
We know that AC = 14 meters and CE = x.
So x² = 14² + x²
x² = 196 + x²
x² = x² + 196
0 = 196
x = √196 = 14
Therefore, the length of height CE is 14 meters.

Now, we are told that a recent survey of 37 million citizens in the United States, 5 million were planning to start a new degree program or continue their education in the next year. Thus, we can say that;
Total number of people in survey = 37 million
Number of people planning to start a new degree program or continue their education in the next year = 5 million
Thus;
P(People starting new program) = 5 million/37 million

Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
There are several types of functions in math. Some important types are:
Injective function or One to one function: When there is mapping for a range for each domain between two sets.
Surjective functions or Onto function: When there is more than one element mapped from domain to range.
Polynomial function: The function which consists of polynomials.
Inverse Functions: The function which can invert another function.

What do you add to 5 5/8 to make 7 as an improper fraction?
Answers
Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
PLEASEEEE GIVE BRANLIEST
Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.
To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.
Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.
45/8 + x = 7
To find x, we can subtract 45/8 from both sides of the equation:
x = 7 - 45/8
x = 1 7/8
So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
the scatter plot shows the number of hours Nisha works an d the numbers of pairs of ghungaroos she makes the equation y= 4.75x - 2.5 is a good line fit for the data. using the equation of the line how many hours will it take Nisha to make 64 pairs of ghungaroos
Answers
The hours that it would take Nisha to make the gungharoos is 301.5 hours
How to solve for the hoursThe equation of the line in the scatter plot is given as
y= 4.75x - 2.5
Where x is the number of ghungaroos that Nisha would make
We have to put in the value of x as 64 because the question tells us that She made a total of 64 gungharoos
Hence we would have:
y = 4.75 * 64 - 2.5
y = 304 - 2.5
y =301.5
The hours that it would take Nisha to make the gungharoos is 301.5 hours
