Question

A population of bacteria is growing according to the exponential model `P = 100e^(70t)`, where P is the number of colonies and t is measured in hours. How many colonies are present initially?

Answer 1

Initially, `100` colonies were present.

Explanation:

To find the initial no. of colonies, means to find the same at time `t=0`, and, for this we have to just substitute `t=0` in the given eqn. to get the the value of `P`

Hence, `P=100e^0=100*1=100`

Therefore, initially, `100` colonies were present.
