Do you mean the hypotenuse of the triangle?

If so, you can use pythagorean theorem:

a^2 + b^2 = c^2

11^2 + 8^2 = c^2

121 + 64 = 185 = c^2

c = sqrt(185) = 13.6

Change this radical to an algebraic expression with fractional exponents.<br> √x^3

So here is how we are going to solve this:
The power of the given expression is 3 and the root is 5. So in writing a fractional exponent, we just have to make 3 as the numerator. So multiply both sides by 3/5 to take the root sign off and the final answer would be x^3/5. 3/5 is the power. Hope this answer helps.

Hey can you please help me posted picture of question

The inverse functions have a property that the composition of two inverse functions always results is x.

From the given options, only the pair given in option B result in the composition equal to x.

$F(x)= \frac{12}{x}-18 \\ \\ 
G(x)= \frac{12}{x+18} \\ \\ 
F(G(x))= \frac{12}{ \frac{12}{x+18} }-18 \\ \\ 
F(G(x))= \frac{12(x+18)}{12}-18 \\ \\ 
F(G(x))=x+18-18=x$

This proves, F(x) and G(x) are inverse of each other.

So the answer to this question is Option B
