The population is increasing every year. so we use exponential growth function
Where 'a' is the initial population
r is the rate of increase
x is the years
y is the final population
In 2015, the population of a small town in Florida is 95
Initial population a= 95
r= 15%= 0.15
x = 2023 - 2015 = 8 years
Plug in all the values and find out y
y = 290.607
The population in 2023 is 291
Answer:

Step-by-step explanation:
<u>Step 1: Define</u>
-15x + 5 = -10x + 25
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 15x on both sides: 5 = 5x + 25
- Subtract 25 on both sides: -20 = 5x
- Divide 5 on both sides: -4 = x
- Rewrite: x = -4
The length of the unknown side length, |AB|, is 6.97
<h3>Trigonometry</h3>
From the question, we are to determine the value of the unknown side length
The unknown side length is the hypotenuse
Using SOH CAH TOA
We can write that
sin 35° = 4/|AB|
∴ |AB| = 4 /sin35°
|AB| = 4 /sin35°
|AB| = 6.97
Hence, the length of the unknown side length, |AB|, is 6.97

You find the circumference of a full circle so 2πr =43.98
then divide by 4=10.995
so the answer is 10.995cm
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
