Given that f(x)= x^3/4 +6 a) Find f(4) b) Find f^-1(x) c) Find f^-1(8)

Anna35 [415]

$f(4)=\dfrac{4^3}{4}+6=4^2+6=16+6=22$

$\begin{aligned}\\&y=\dfrac{x^3}{4}+6\\&4y=x^3+24\\&x^3=4y-24\\&x=\sqrt[3]{4y-24}\\&f^{-1}(x)=\sqrt[3]{4x-24}\end$

$f^{-1}(8)=\sqrt[3]{4\cdot8-24}=\sqrt[3]{8}=2$

What is the area of a section of pavement that is 20 ft wide and 70 yd long?

myrzilka [38]

Answer:

A = 4200 ft^2

Step-by-step explanation:

We know the formula for area is

A = l*w

We need to have the same units

convert yd to ft

1 yd = 3ft

Multiply each by 70

70 yds = 210 ft

A = 210 *20

A = 4200 ft^2

How to Write 3/9 in simplest form.

White raven [17]

To write it in simplest form, you must find a common factor.

In $\frac{3}{9}$ , 3 is a factor of both 3 and 9

3÷3=1 and 9÷3=3

So $\frac{3}{9} = \frac{1}{3}$

$\frac{1}{3}$ is your answer in simplest form.
