Question

A scientist studied the population growth of a bacteria. He concluded that the population of the bacteria triples every 30 minutes. Find out the population of the bacteria after 2 hours (120 minutes). PLS SHOW STEPS

Answer 1

Step-by-step explanation:

let us say the bacteria at beginning was 'x'

after 30 min bacteria has tripled =3×x

after 1 hour =3 × (3x) = 9x

after 1 hour 30 min = 3 × 9x = 27x

after 2 hours = 3 × 27x = 81x

so it is growing at 3^n
