Answer:
If the sphere has a radius of 4, you can use the equation: V=4/3(pi)(r)^3
Step-by-step explanation:
V=4/3(pi)(r)^3
V=4/3(pi)(4)^3
Answer:
5 inches
Step-by-step explanation:
It will take 15 years for the population to quadruple
Step-by-step explanation:
The formula for continuously compounding rate is , where
- A is the future amount
- P is the initial amount
- r is the interest as a decimal
- t is the time in years
Assume that the initial population is P
∵ The initial population = P
∵ The growth rate = 9% ⇒ compounded continuously
∴ r = = 0.09
∵ The population will quadruple in t years
∴ A = 4P
- Substitute these values in the formula
∵
∴
- Divide both sides by P
∴
- Insert ㏑ to both sides
∴ ㏑(4) = ㏑( )
∵ ㏑( ) = n
∴ ㏑ (4) = 0.09 t
- Divide both sides by 0.09
∴ t = 15.4
∴ t = 15 years to the nearest whole number
It will take 15 years for the population to quadruple
