Answer:
2.2%
Step-by-step explanation:
Given the following :
Population in year 2000 (A) = 4.2 million
Expected population every 32 years = 2 *A
The growth rate per year =?
The population figure after 32 years = (2 * 4.2 million) = 8.4 million
Using the exponential growth formula :
P(t) = A × (1 + r)^t
(1 + r) = g = Total growth percent
A = Initial population
t = time
P(t) = 8.4 million
8,400,000 = 4,200,000 × g^32
g^32 = (8400000/4200000)
g^32 = 2
Taking the root of 32 on both sides
g = 1.02189714865
g = (1 + r)
1.02189714865 = 1 + r
r = 1.02189714865 - 1
r = 0.02189714865
.rate = 0.02189714865 * 100
= 2.18971486541%
= 2.2% ( nearest tenth)

Answer:
126
Step-by-step explanation:
4 * 12 = 48
+ 48 more + 6
48 + 72 + 6 = 126
i really hope that is correct
i noticed it saide round to nearest hundredth, so sorry if I am wrong
Answer: Yes that's correct
Work Shown:
(-1)^2-(-2-(9-1))
1-(-2-(8))
1-(-2-8)
1-(-10)
1 + 10
11
Note that (-1)^2 = (-1)*(-1) = 1, and subtracting a negative turns into a positive.
