ANSWER

EXPLANATION
The given function is:

and



To find g(f(-1)), we substitute x=-1, to obtain;

We simplify the square in the denominator to get,

We now add the denominator to obtain;

Answer:
it looks like it would just be -1
Step-by-step explanation:
there two -x and two positive x which would cancel out. three positive 1 and four negative 1. -4+3= -1
that's the best I could come up with
Answer:
The exact value of its surface area = 144π m²
The exact value of its volume = 288π m³
Step-by-step explanation:
∵ The diameter of the sphere is 12m
∴ The radius of the sphere = 12 ÷ 2 = 6m
∵ The surface area of the sphere = 4πr²
∴ The surface area = 4 × π × 6² = 144π m²
∵ The volume of the sphere = 4/3 πr³
∴ The volume =
= 288π m³
We know that the price of all the fabrics is the same. However, the length of the fabrics is different. We have to determine which fabric is the longest.
Option A:
= 8.6
Option B:
= 8.25
Option C:
= 8.6667
Option D:
= 7.33....
Hence, the longest fabric is the one given in option C, and its length is 8.6667
The answer to this is Y = 1
