A rectangle has a length that is twice the meaure of its width. Perimeter is 54. What is the area
Goshia [24]
L = 2W
P = 2L + 2W
Plug 2W in for L.
54 = 2(2W) + 2W
54 = 4W + 2W
54 = 6W
Divide both sides by 6
W = 9
L = 2* 9
L = 18
A = L * W
A = 9 * 18
A = 162 units^2

For the function f (x) = 3 (x + 7), find -1().
AlekseyPX

Given:

The function is f(x)=3(x+7)^{\frac{1}{4}}.

To find:

The function f^{-1}(x).

Solution:

We have,

f(x)=3(x+7)^{\frac{1}{4}}

Substitute f(x)=y.

y=3(x+7)^{\frac{1}{4}}

Interchange x and y.

x=3(y+7)^{\frac{1}{4}}

Divide both sides by 3.

\dfrac{x}{3}=(y+7)^{\frac{1}{4}}

Taking power 4 on both sides.

\left(\dfrac{x}{3}\right)^4=y+7

Subtract 7 from both sides.

\left(\dfrac{x}{3}\right)^4-7=y

y=\left(\dfrac{x}{3}\right)^4-7

Substitute y=f^{-1}(x).

f^{-1}(x)=\left(\dfrac{x}{3}\right)^4-7

Therefore, the correct option is C.
