A single-cell amoeba doubles every 4 days. How long would it take one amoeba to produce a population of about 10,000 amoebae?

a) If exponential growth continues, how long will it take for the number of mathematics degrees awarded per year to increase to 17-fold? b) If 250 mathematics degrees were awarded in 1955, in...

I can't understand how to solve for t, formula isn't working

The population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year. Assuming that the world population follows an exponential growth model, find the projected...

Determine in which year the population will pass 50,000.

In an effort to control vegetation overgrowth, 115 rabbits are released in an isolated area free of predators. After 2 years, it is estimated that the rabbit population has increased...

The population of rabbits in a forest follows the law of exponential growth. If 90 rabbits are present initially and there are 180 after 3 years, how many will there be in 4 years?

Pretty self explanatory. It's an exponential function but I keep getting different answers when I try to calculate it.
