A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.

Answer:

The box will move toward you with a force of 10N

Explanation:

If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
