First think of the form a^2 + 2c + c^2

c in the question is clearly 3.

So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.

So it will be (x^2+3)^2 = 17

So the choice number 3 is the answer.

Hope this helps!

Answer:

(1,6) , (2,7) , (3,8) , (4,9) , (5,10)

Step-by-step explanation:

Given equation: y = x + 5

when x = 1, y = 1 + 5 = 6

(1,6)

when x = 2, y = 7

(2,7)

when x = 3 , y = 8

(3,8)

when x = 4 , y = 9

(4,9)

when x = 5 , y = 10

(5,10)

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.
