There are 5^5 students on the school and 5^2 students per class.
So, think:
1 class ----------- 5^2 students
x classes ---------- 5^5 students
Multiply:
1 . 5^5 = x . 5^2
So,
5^5 = x.5^2
x =
x =
x =
x = 125
There are 125 classes.

Answer:
The growth value of the function is One-third ⇒ True (2nd)
The function shows exponential decay ⇒ True (3rd)
The function is a stretch of the function ⇒
True (4th)
Step-by-step explanation:
* <em>Lets revise the form of the exponential function</em>
- The general form of the exponential function is
where "a" is the initial amount and "b" is the growth factor
- If b > 1, then f(x) is exponential growth function
- If 0 < b < 1, then f(x) is exponential decay function
* <em>Lets solve the problem</em>
- The exponential function
∴ The initial value is 3
∴ The growth factor is
∵ The growth factor is less than 1
∴ f(x) is exponential decay function
* Lets chose the true statements
# The initial value of the function is One-third ⇒ Not true
because the initial value is 3
# The growth value of the function is One-third ⇒ True
because the growth factor is
# The function shows exponential decay ⇒ True
because the growth factor is less than 1
# The function is a stretch of the function
⇒ True
because stretched vertically means multiply f(x) by constant greater
than 1 and 3 is greater than 1
# The function is a shrink of the function ⇒ Not true
because the growth factor is not 3
