Which represents the inverse of the function f(x) = 4x?
vazorg [7]

Option D: h(x)=\frac{1}{4}x is the inverse of the function f(x) = 4x

Explanation:

Given that the function is f(x)=4x

We need to determine the inverse of the function.

<u>Inverse of the function h(x):</u>

The inverse of the function can be determined by interchanging the variables x and y and then solving the function for y.

Thus, the function is written as,

y=4x

Interchanging the variables x and y, we have;

x=4y

Dividing both sides by 4, we get;

\frac{1}{4}x=y

Thus, the inverse of the function is h(x)=\frac{1}{4}x

Hence, Option D is the correct answer.

Look at Arnold's attempt to solve the equation for b:
Tasya [4]
His mistake was in multiplying the 3 with the 12. He should have divided it from the 12 because that would have gotten rid of the 3 with the variable. It would also lead to the correct answer, which is b=4

To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.

The total volume = 1/2 * 4/3 π (15)^3  + π (15)^2 * 85

= 67151.5 ft^3.
