Answer:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$

Step-by-step explanation:

So this is a composition of functions. Think back to solutions of equations. You would have to put the equation into the other equations. It's like this!

So I graphed it like this on desmos:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$

Volume of a Sphere Formula: $\displaystyle V = \frac{4}{3} \pi r^3$

r is radius

Step-by-step explanation:

Step 1: Define

Identify variables

r = 8 ft

Step 2: Find Volume

Substitute in variables [Volume of a Sphere Formula]: $\displaystyle V = \frac{4}{3} \pi (8 \ ft)^3$
Evaluate exponents: $\displaystyle V = \frac{4}{3} \pi (512\ ft^3)$
Multiply: $\displaystyle V = \frac{2048}{3} \pi \ ft^3$
Estimate: $\displaystyle V = 2144.66 \ ft^3$
