Write an exponential growth function to model each situation,
15. Initial value: 20
Growth factor: 1.25
Answers
Answer: f(x)=20(1.0125)^t
Step-by-step explanation:
use the formula P(1+r)^t when considering exponential growth (make it 1-r if decay)
P - principal (initial) value
r - growth rate (as a decimal! so divide by 100)
t - time (can be years, months, days, etc)
so now that we know the formula, just plug in everything you know!
P=20, r=0.0125, t=x
so the function is
20(1+0.0125)^t or 20(1.0125)^t
since we dont have a defined time, that becomes the variable for x, the one we can manipulate, so if they ask for 10 years, just replace t with 10!

Answers
Answer: I'm not 100% sure what you're asking for, but the full answer to the last question is a .25 increase or a 25% increase.
Step-by-step explanation:
First, we need to see how much it increases.
We would take 1.50, and minus 1.25 from it to get our first answer of .25.
To get the percentage of increase, we would take our .25, and times it by 100 equaling 25%.

4x - 2(x - 2) = -9 + 5x - 8
Answers
Step by step
4x -2(x - 2) = -9 +5x -8
Distribute
4x -2x +4 = -9 +5x -8
Combine
2x + 4 = 5x -17
Subtract 5x from both sides to isolate variable
2x -5x +4 = 5x -5x -17
Combine
-3x +4 = -17
Subtract 4 from both sides to combine constants
-3x +4 -4 = -17 -4
Combine
-3x = -21
Divide both sides by -3 to solve
-3/-3 x = -21/-3

The ages of John and Sam are 47.34 and 17.66 years respectively.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.
Let, The age of Sam be 'x'.
Therefore, 2x + 12 + x = 65.
3x = 53.
x = 17.66.
So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.
