Answer:
1. -6
Step-by-step explanation:
f(x)=x²-9
g(x)= x-3
1. (f+g)(2) =
(2²-9)+(2-3) = (4-9)+(2-3) = (-5)+(-1)= -6
Answer:
648pi
Step-by-step explanation:
V=pi*r^2*h
V=pi*9^2*8
V=pi*81*8
V=648pi
Let's rephrase this:
Here:
There are 3 geometric transformations:
1. Rotation
Shapes are rotated or turned around an axis.
2. Reflection
