Answer:
C. 36π
Step-by-step explanation:
The formula for volume of a sphere is:
V=⁴/₃πr³
We are given diameter: 6
To convert to radius, divide by 2.
6÷2=3. R=3
Plug in to formula
V=⁴/₃π3³
Simplify with multiplication
V=⁴/₃π27
V=36π
Add 16 to both sides
3p<36 divide both sides by 3
p<12
Answer:
14
Step-by-step explanation:
f(x)=2x+7
f(4)=2(4)+7
=8+7
=15
f(-4)=2(-4)+7
=-8+7
=-1
f(4)+f(-4)
=15+(-1)
=14.
The future value of her investment will be
.. 3000*(1.1^35 -1)/(1.1 -1) ≈ 813,073.11
That supports 30 years of annual payments of
.. 813,073.11*(.1)/(1 -1.1^-30) = 86,250.18
