The population of mice in Alfred is given by P(t)=2964e^6t, where t is in years since 1986. The rate of change of the population is given by the formula
(17784e^(6t)) mice/yr. In year 1990 the population changes by approximately
471082547957136 mice. In 1990 213377088722825 mice died, which means that how much mice were born that year?

Perimeter of triangle CDE = 56

Step-by-step explanation:

Here, we want to find the perimeter of CDE

mathematically, when the measure of the inner triangle is half of the respective sides of the bigger

What this mean is that for each side that one of the side of the inner triangle faces, the measure on the bigger triangle is twice

Thus, 9 represents a length of 2(9) = 18 on the bigger triangle

Also, 7 will represent a length of 2(7) = 14 on the bigger triangle

So, now we have the complete sides of the bigger triangle

The measure of the perimeter is simply the addition of the respective side lengths

We have the perimeter of the large triangle as;

24 + 18 + 14 = 56
