Answer:

A. $f^-^1(x)=x^2+8; x\geq 0$

Step-by-step explanation:

I took the test and got it correct, using inverse operating functions, it gives you the detail of the square root of variable x, which would obviously become x^2, this is because the opposite of a square root is a power of 2, with the ending of -8 become a positive, still with the x becoming <u>greater than or equal</u> to ZERO [0]

Which expression is equivalent to RootIndex 3 StartRoot x Superscript 5 Baseline y EndRoot?

IRINA_888 [86]

Answer:

The answer is " $x^{\frac{5}{3}}y^{\frac{1}{3}}$ "

Step-by-step explanation:

Given value:

$\to \bold{ \sqrt[3]{x^5y} }$

$\to \sqrt[3]{x^5y} =(x^5y)^{\frac{1}{3}}$

formula:

$\bold{(a.b)^n=a^nb^n}$

$\to (x^5y)^{\frac{1}{3}}= x^{\frac{5}{3}}y^{\frac{1}{3}}$

The final value is: $\boxed{\boxed{ x^{\frac{5}{3}} \cdot y^{\frac{1}{3}}}}$

Find the height of a square pyramid that has a volume of 8 cubic feet and a base length of 2 feet. . . a. 6 feet. b. 16 feet. c.

exis [7]

Volume a square pyramid is expressed as the one third of the product of the base area and the hight of the shape.

Volume = (1/3)*(base area)* height

Substituting the given values, we have:

(1/3)*(2 * 2) * h = 8

h = 8*3 / (2 * 2)

h = 6 ft

Therefore, the correct answer among the choices is option A.
