There are 72 mice in Mouse Town. The population of mice in mouse town doubles every 8 months. How long ago was the population of mice less than ten? Make brainlest ( don't remember what's it called)

aka 24 months

============================================================

Explanation:

The population follows this function

y = 72*(2)^x

where x is the number of eight-month periods and y is the population.

So if for instance we had x = 2, then it represents two periods of 8 months each, giving 2*8 = 16 months total.

Normally with timescale problems like this, negative time values do not make sense. However, having x be negative will allow us to look back in time to figure out when y < 10.

Let's see what x is when y = 10.

y = 72*(2)^x

10 = 72*(2)^x

10/72 = 2^x

0.1389 = 2^x approximately

log(0.1389) = log(2^x)

log(0.1389) = x*log(2)

x = log(0.1389)/log(2)

x = -2.8479 also approximate

-----------

If x = -2, then,

y = 72*(2)^x

y = 72*(2)^(-2)

y = 18

and if x = -3, then,

y = 72*(2)^x

y = 72*(2)^(-3)

y = 9

This means that 3 eight-month periods ago, the population was less than 10 mice.

So this is 3*8 = 24 months = 2 years.

-----------

Checking the

If we were to start at 9 mice and double the population, then it goes to 18 mice. Then that doubles to 36, and so on.

Here's a table showing this process

The table confirms the answer of 24 months = 2 years.

The process of using logs is almost like reversing this process shown in the table.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
