Answer:

8x+24

dimensions of the photograph

length - 7 inch

width - 5 inch

dimensions of the photo frame is 2x larger than both width and length

length - 7 + 2x

width - 5 + 2x

the perimeter is sum of all 4 sides

Perimeter = 2(7 + 2x) + 2(5 + 2x)

= 14 + 4x + 10 +4x

= 24 + 8x

correct answer is 8x+24

A study is done on the population of a certain fish species in a lake. Suppose that the population size P(1) after years is give

Andre45 [30]

Answer:

Growth
22%

Step-by-step explanation:

Given function:

$P(t) = 400(1.22)^{t}$

Initial population size is when t = 0

P(0) = 400(1.22)⁰ = 400(1) = 400

The multiple of 1.22 is applied every year, so the ratio of change is:

1.22 = 122% = 100% + 22%

This is an exponential growth which represents 22% annual growth.
