T=number of years since start of the study.
y=city´s population.
first year:
y=390,000+0.073(390,000)=390,000(1+0.073) (=418470)
Second year:
y=(390,000(1+0.073) + 0.073(390,000(1+0.073) =
=390,000(1+0.073) (1+0.073)
=390,000(1+0.073)²
(≈449,018.31)
Third year: if you calculate it you would have:
y=390,000(1+0.073)³
Fourth year: if you compute it you would have:
y=390,000 (1+0.073)⁴
t th year:
y=390,000(1+0.073)^t
Answer: y=390,000(1+0.073)^t
The left side−8 is less than the right side48
,which means that the given statement is always true.
True
Commutative property of addition is being used.
This means that you can switch around where the numbers are and still get the same answer.
Hope this helps!
Given the following question:
Lable all the sides of the triangle:
Hypotenuse is the missing side
Right angle is the opposite
Adjacent is equal to 21
We have all of our sides so now we won't get them mixed up when finding the missing value of this triangle.
sin =
opp/hyp
cos =
adj/hyp
tan =
opp/adj
Since we are given the adjacent side and we are trying to find the hypotenuse we will solve for cos since we have the adjacent side but we need the hypotenuse
cos(35)=21/x
Now solve:
