Hello, can you help me with those two calc 2 questions from the indefinite integral chapter.

Question One:

The cost of maintaining a home generally increases as the home becomes older, Suppose that the maintenance costs increase at a rate of 1500e-5* (dollars per year) when the home is x years old. (a) Find a formula for the total maintenance cost during the first x years. (Total maintenance should be zero at * = 0.) M(x) = (b) Use your answer to part (a) to find the total maintenance cost during the first 4 years. (Round your answer to the nearest dollar.) $An ice cube tray filled with tap water is placed in the freezer, and the temperature of the water is changing at the rate of -90 0.25 degrees Fahrenheit per hour after t hours. The original temperature of the tap water was 65 degrees. (a) Find a formula for the temperature of water that has been in the freezer for t hours. TO) = (b) When (in hours) will the ice be ready? (Water freezes at 32 degrees. Round your answer to the nearest hour.) hours
