A school has 200 students and spends $40 on supplies for each student. The principal expects the number of students to increase
34kurt

Step-by-step explanation:

The predicted number of students over time, S(t)

Rate of increment is 5% per year.  

A function 'S(t)' which gives the number of students in school after 't' years.  

S(0) means the initial year when the number of students is 200.

S(0) = 200  

S(1) means the number of students in school after one year when the number increased by 5% than previous year which is 200.  

S(1) = 200 + 5% of 200 = = =  

S(2) means the number of students in school after two year when the number increased by 5% than previous year which is S(1)  

S(2) = S(1) + 5% of S(1) = = =  

.  

.  

.  

.  

.  

Similarly  

The predicted amount spent per student over time, A(t)

Rate of decrements is 2% per year.  

A function 'A(t)' which gives the amount spend on each student in school after 't' years.  

A(0) means the initial year when the number of students is 40.  

A(0) = 40  

A(1) means the amount spend on each student in school after one year when the amount decreased by 2% than previous year which is 40.  

A(1) = 40 + 2% of 40 = = =  

A(2) means the amount spend on each student in school after two year when the amount decreased by 2% than previous year which is A(1)  

A(2) = A(1) + 2% of A(1) = = =  

.  

.  

.  

.  

.  

Similarly  

The predicted total expense for supplies each year over time, E(t)

Total expense = (number of students) ×  (amount spend on each student)

E(t) = S(t) × A(t)

(NOTE : The value of x in all the above equation is between zero(0) to ten(10).)

Help asap <br> Use the graph to find the indicated value of the function.
kipiarov [429]

f(-2) means the x value is -2 and you need to find the y value at that point.


At x = -2 the line crosses the y axis at y = 2

f(-2) = 2

Divide! If you add three and four, you get seven. Subtracting four from seven, you get three. If you multiply three and four, you get twelve. If you then divide by four, you get back to 3. I hope this helped!
