Answer:
-10x^2 +9+8x^2-5x+7=-2x^2-5x+16
Volume =πr²*h=π*7²*4=196π
answer B
Answer:
See explanation
Step-by-step explanation:
1. The given function is

The domain values are: x=0, 2, -1, 4, -2
When x=0

When x=2,

When x=-1

When x=4

When x=-2

2. The given function is

When x=3,

Similarly,




2: Midpoint of segment AC is given as B3: Given4: Knowing that AC~=BC, AC~= DE
Their intersection is 7 because is you look at the coordinates of both A and B they have 7 in common
