Question 1

The rate of expenditure on a particular machine is given by

where x is time measured in years. Maintenance costs through the second year are $96. Find the total maintenance function.
◦ M(x) = 5(x² + 5)^3/2 - 39
◦ M(x) = 5(x² + 5)^3/2 + 81
◦ M(x) = 15(x² + 5)^3/2 + 81
◦ M(x) = 15(x² + 5)^3/2 - 39

Question 2

The rate of growth of profit (in millions) from an invention is approximated by

where x represents time in years. The total profit in year 2 that the invention is in operation is $15,000. Find the total profit function P(x).
◦ P(x) = -0.5e^-x²+ 24,000
◦ P(x) = -

e^-x²- 24,000
◦ P(x) = -0.5e^-x²+ 0.024
◦ P(x) = -

e^-x²- 0.024
