$126.33
Step-by-step explanation:
$379/3 = $126.33
The growth factor that could be used to model the population will be 1.04. Then the correct option is D.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.
The population is increasing by 4% per year.
Then the growth factor that could be used to model the population will be
Growth factor = (1 + 4%)
Growth factor = (1 + 0.04)
Growth factor = 1.04
The growth factor that could be used to model the population will be 1.04.
Then the correct option is D.

Answer:
7. 4
8. 7
Step-by-step explanation:
7. 
Cross multiply


(division property of equality)


8. 
Cross multiply


(addition property of equality)

Divide both sides by 6


Answer:
2 possible coordinate pairs
N (8, 17) OR (-12, -3)
Step-by-step explanation:
The rule:
(x, y) => (x + 10, y + 10) OR (x - 10, y -10)
(-2 + 10, 7 + 10) OR (-2 - 10, 7 -10)
(8, 17) OR (-12, -3)
Hope this helps!
