suppose the real risk-free rate is 2.50% and the future rate of inflation is expected to be constant at 2.80%. what rate of return would you expect on a 5-year treasury security, assuming the pure expectations theory is valid? disregard cross-product terms, i.e., if averaging is required, use the arithmetic average.

Answer

It will take (t) = 24 hours to reach 300 .

Step by step explanation

It doubles every 15 hours.  initial bacteria = 100

We need to find how long it take for the bacteria cells to increase to 300.

300 = 100(2)^t/15

300/100 = 2^t/15

3 = 2^t/5

Taking "ln" both sides, we get

ln(3) = t/15 ln(2)

t/15 = ln(3)/ln(2)

t/15 = 1.585

t = 1.585 * 15

t = 23.78 hours

t = 24 hours to nearest whole hours.

Thank you.
