Answer:
A. the proper steps that should have been taking would be to first would be to raise 2 to the power of 3, which would give you 8. Then raise it to the power of 1. So the most likely error is C. they added the exponents.
Answer:
C and D
Step-by-step explanation:
To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.
(7, - 2)
2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution
(- 5, - 4)
2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution
(4,
)
2(4) + 10(
) = 8 + 4 = 12 → hence solution
(- 5,
)
2(- 5) + 10(
) = - 10 + 22 = 12 → hence solution
Answer: a) 236,000.
b) 2021
Step-by-step explanation:
Given : Population Growth The population P (in thousands) of Oriando,Florida from 1980 through 2009 can be modeled by
(1)
where t = 0 corresponds to 1980.
Then , for 2009
t= 2009-1980=29
a. ⇒The population of Phoenix in 2009 = 


Hence, the population of Orlando in 2009 was about 236,000.
b) Substitute p= 300 in (1) , we get
(Divide both sides by 130)
Taking Natural log on both sides,


Hence, The year Orlando will have a population of 300,000 =1980+41 =2021
