Maintenance costs for an apartment building generally increase as the building ages. From past records, it is estimated that the rate of increase in maintenance costs for this type of building is approximated by Where x is the age of the complex in years and M (x) is the total accumulated cost of maintenance for x years. Write a definite integral that will give the total maintenance costs from the end of the second year to the end of the seventh year of use and evaluate it.

M(x) = 29480 units

Step-by-step explanation:INCOMPLETE QUESTION.

Information describing the equation of maintenance costs for the type of building is needed, we can either work with a maintenance costs equation

or with any other equation from which to get the maintenance costs equation.

Particularly similar statement problem give M´(x) = 90*x² + 5000, therefore if we integrate such equation we get M(x) as maintenance cost equation. We will do that then

M´(x)  = 90*x² +  5000

∫M´(x)  =  M(x)  = ∫(90*x² +  5000 ) dx

but we require costs from the end of second year up to the end of the 7 th year then

M(x)  = ∫₃⁷ (90*x²  +  5000) dx

M(x)  = (90/3 )*x³   +  5000*x) |₃⁷

M(x)  = 30*(7)³ + 5000* (7)  - 30*(3)³ - 5000*3

M(x)  =  10290 + 35000 - 810 - 15000

M(x)  =  29480 $

ask the math teacher she or he would know lol.
