If b1,b2 are nonzero, the value of {b1}/{b2} will be 3/2.

If a is inversely proportional to b. Let a1,a2 be two nonzero values of a such that {a1}/{a2}={2}/{3}. Let the corresponding b values be b1,b2. If b1,b2 are nonzero

a = k *1/b

2/3 =k * 1/b1 /k * 1/b2 [k = constant cancels out]

2/3 =1/b1 * b2

2/3 = b2/b1

b1 =3 and

b2 =2. Therefore:

b1/b2 =3/2.

Another way of looking at it, is this:

When a1 =2, b1=1/2

When a2 =3, b2=1/3

So, when a1/a2 = 2/3, then:

b1/b2 =(1/2) / (1/3) =(1/2) x (3/1)

The number of years in the investment period, given the account balance and the simple interest, is C. 7 years.

To find the investment period, you can use the equation given on the account balance after a number of years, with " t " representing that number of years. And with simple interest,

With the formula being A = 5,000 x ( 1 + 0.025 t ), the investment period would be :

5, 875 = 5,000 x ( 1 + 0.025 t )

5, 875 = 5, 000 + 125 t

125 t = 5, 875 - 5, 000

The side lengths given as 4 8 9 shows that it is an obtuse Triangle.

It should be noted that to determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute

In a situation if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse

This will be:

The subtraction is equal to the mixed number below:

9 - (3 + 7/8) = 5 + 1/8

Here we want to solve the expression below:

9 - (3 + 7/8)

So we have a whole number and a mixed number.

First we can subtract the two whole numbers so we get:

9 - (3 + 7/8) = (9 - 3) - 7/8

                   = 6 - 7/8

Now, to have a mixed number the fraction needs to be positive, so we can write:

Express the equation properly

This gives

120 + 18 1/4x = 180 –13/4x

Collect the like terms in the above equation

So, we have the following representation

18 1/4x + 13/4x = 180 - 120

Evaluate the like terms in the above equation

So, we have the following representation

The line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

On the y-axis, this value c is referred to as the intercept.

Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

y = 1/3x + 4 is the line that crosses (1,2) and is perpendicular to it.

To ascertain the equation of the line, utilize the procedures below:

Step 1: Two lines that are perpendicular to one another have the following slopes:

mm' = 1

Where the slopes of the lines are m and m'.

Step 2 - The line that is perpendicular to the line (y = 1/3x + 4) has the following slope:

1/3 * m' = -1

m' = -3

Step 3: The equation for a line passing through the points (1, 2) and having a slope of -3 is as follows:

(y - 2) = -(x - 1)

Implicate the equation above:

y = -3x + 5

Therefore, the line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).

Answer:

Step-by-step explanation:

You want to know the pre-tax price if the price with 5% tax added is $21.

The added tax is 5% of the original amount (x), so the amount with tax added is ...

  $21 = x + 0.05x = 1.05x

  $21/1.05 = x = $20 . . . . . divide by the coefficient of x

The cost before tax was added was $20.

Step-by-step explanation:

Percentage left after the tax percentage is

100%-5%=95%

95% is equal to 95/100 = 0.95

therefore, the cost after tax divided by the percentage that is left after the tax percentage

costs after tax is 21 dollars which is

In Euclidean geometry, an angle is a shape that is made up of two rays, known as the hood's sides, that meeting at a middle point known as the wall's apex. Two rays may combine to form an angle in the planes where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two photons or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, sometimes known as two sides of the angle, converge.

The value of the combined function f(g(x)) will be -16x^2+88x-120.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. 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.

Now,

Given functions are f(x)=1-x^2 and

g(x)=11-4x

The relationship between the elapsed time in days, d, since the video was uploaded and the total number of views, v, that the video received is modeled by the equation,

v = 4^(1.25d)

We have to find d when v = 1024

1024 = 4^(1.25d)

We have the rule for exponents aᵇⁿ = (aᵇ)ⁿ

1024 = [tex](4^{1.25} )^d[/tex]

Taking logarithms on both sides,
