Question

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6 days after inoculation? Y = 1,000(1.15)6 2,313 bacteria y = 1,000(1.15)7 y = 1,000(1.5)5 y = 1,000(1.5)6 11,391 bacteria

Answer 1

Answer:AAAAAAAAAAAAAAAAAAAA

Answer 2

The correct option is Y = 1,000(1.15)6 2,313 bacteria

Explanation:

According to the given statement a growth medium is inoculated with 1,000 bacteria.

Bacteria grow at a rate of = 15% = 0.15

Add 1 to make it easier = 0.15+1 = 1.15

We have to find the population of the culture 6 days after inoculation.

= 1000(1.15)^6

=1000(2.313)

= 2313 bacteria

The population of the culture 6 days after inoculation = 2313 bacteria

Therefore the correct option is Y = 1,000(1.15)6 2,313 bacteria....
