Answer:
yes.
Step-by-step explanation:
Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. Thus, the equation of this line is y=-8x+5.
Answer:
The volume of the hemisphere is 496741.6 m³
Step-by-step explanation:
The volume of an sphere is given by:

In which
and r is the radius.
An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

In this question:
. So

The volume of the hemisphere is 496741.6 m³
F(x)=2x
G(x)=x+5
Now
F(g(x))=2(x+5)
=2x+10
G(f(x))=2x+5
