Answer:
The angle of elevation is equal to 68.2 degrees
Step-by-step explanation:
As you can see from the image below we are trying to find the angle on the bottom right.
We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.
sin x = 13/14
divide:
sin x = 0.9285714286
now we need to use sin^-1
sin^-1 (0.9285714286) = 68.21321071
Round 68.21321071 to the nearest tenth:
68.2
The angle of elevation is 68.2 degrees!

Answer:
Step-by-step explanation:
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
1. Find the general formula for the sequence
a₁ = 80
r = 4
The general formula is then
aₙ = 80(4)ⁿ⁻¹
Step 2. Find the population in 1984
You want the population at the end of the year.
However, the terms in the sequence represent the population at the beginning of the year
The end of the second year is the beginning of the third year, so you want to evaluate a₃
a₃ = 80(4)³⁻¹ = 80(4)²= 80 × 16 = 1280
