A population of insects grows exponentially. Initially, there were 20 insects and the population of the insects grew by 50% ever

y week. Use a function P(t) P ( t ) that represents the insect population at the end of t weeks. What is the insect population at the end of week 12? Round your answer to the nearest whole number. Enter your answer in the box.

The answer is 8069 insects

P(t) = A * e^(r*t)
P(t) - <span>the insect population at the end of t weeks.
A - the initial number of insects
r - the growth rate
t - number of weeks

P(t) = ?
A = 20
r = 50% = 0.5
t = 12 weeks

P(t) = </span>20 * e^(0.5*12)
P(t) = 20 * 
P(t) = 20 * e^(0.5*12)
P(t) = 20 * 403.43
P(t) ≈ 8069 insects

rusak2 [61]

Answer:

<em>2.983 </em>ft/sec

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute = \frac{60}{20} = 3

Formula for linear speed is given as:

v=\dfrac{2\pi}{60}\cdot r\cdot RPM

Where r is the radius of circular path and

RPM is the number of revolutions per minute.

v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}

Therefore, the linear speed is <em>2.983 ft/sec.</em>
