B) Find the mean and variance of the number that survive
explanation:
The volume for a cube is the cube of any side. side^3
If each sides measures 1 foot, the volume would be 1 ft^3.
2x³+18x²<span>-18x-162 =
2(</span>x³+9x²-9x-81)=
2(x²(x+9)-9(x+9))=
2(x²-9)(x+9)=
2(x+3)(x-3)(x+9)
Answer: k=3
Answer:
f(1) = -7
Step-by-step explanation:
Step 1: Define
f(x) = -x² + x - 7
f(1) = x = 1
Step 2: Substitute and Evaluate
f(1) = -(1)² + 1 - 7
f(1) = -1 + 1 - 7
f(1) = -7
A. Evidence. To support a point you would need something to back it up. That being evidence/facts.
