Answer: 1. muiltply the two volumes 2. 273.32 cubic centimeters are your answers hopefully I'm correct on this.
Answer:
V = 14130 inches cubed
Step-by-step explanation:
the volume formula for a sphere is 
. To solve plug in the values for each part of the equation. Pi will equal 3.14, and r will equal 15.
For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.
S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.
Answer:
8 years
Step-by-step explanation:
100e^(.05t) = 150 . . . . . a better model of the situation
e^(.05t) = 150/100 . . . . divide by 100
0.05t = ln(1.5) . . . . . . . . take natural logs
t = ln(1.5)/0.05 ≈ 8.11 . . . . divide by the coefficient of t
The money has been invested for about 8 years.
Substitute the value of s, which is now 3 into the equation
A = 6(3)^2
A =6(9)
A = 54
