The invasive cane toad shows a population growth rate of 7% per year. How many years will it take for this invasive population to grow from 4 million cane toads to 16 million cane
toads?

Please be quick

Given:

Initial population = 4 millions

Growth rate = 7% = 0.07

Present population = 16 millions

To find:

The time it will take for this invasive population to grow from 4 million cane toads to 16 million cane toads.

Solution:

The exponential growth model is

where, P is present population, is iniital population, r is growth rate and t is time in years.

Substitute P=16, and r=0.07, we get

Divide both sides by 4.

Taking log on both sides.

Approx the value to the next integer.

Therefore, the required number of years is 21.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
