We are given with the initial population and is asked for the final population after n years. in this case, we use the formula P(n) = Po* (1 + r)^n where r is the rate of growth. 1) P(n) = Po* (1 + r)^n P(n) = 8600* (1 + 0.03)^3 P(n) = 9397 people
2) P(n) = Po* (1 + r)^n P(n) = 1500* (1 + 0.02)^4 P(n) = 1624 deers

Answer:
Step-by-step explanation:
The longest side of the given trapezoid is 14 units as per picture.
The ratio or scale factor is 2/7.
<u>The new figure's corresponding side will have the length:</u>
- 14 : 2/7 =
- 14 * 7/2 =
- 49 units

- Sum of Angles: 180(n - 2)°
Step-by-step explanation:
<u>Step 1: Identify</u>
We have a polygon, so n = 4.
- Substitute [SA]: 180(4 - 2)°
- (Parenthesis) Subtract: 180(2)°
- Multiply: 360°
This tells us the sum of all angles in the shape.
<u>Step 2: Solve for </u><em><u>x</u></em>
- Set up equation: 90° + 93° + 89° + x° = 360°
- Combine like terms: x° + 272° = 360°
- Isolate <em>x</em>: x = 88°
With the 15% coupon, you will get $1,875. (Because 15% of the bond's price $12,500 is $1,875.) Solution: 0.15 x 12500 = 1875
So $1,875 is to be divided by the actual price of the bond which is $10,750. (1, 875 ÷<span> 10,750 = 0.1744 convert this to percent to get the rate of return)
0.1744 = 17.44 %
The rate of return is 17.44%.</span>
