Answer:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$

Step-by-step explanation:

For this case we have the following function:

$y = 300 (2)^x$

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

$x = 66 minutes *\frac{1period}{22 minutes}= 3$

So then we need to replace the value of x =3 and we got:

$y= 300 (2)^3 = 2400$

Find the ratio of the similar known sides:

1.34/2 = 0.67

The smaller triangle is 0.67 the size of the larger one.

Multiply the similar sides by the ratio:

DE = 4 x 0.67 = 2.68

FE = 3 x 0.67 = 2.01
