Solve the problem.A basement is flooded with 230 cubic feet of water. Water can be pumped out of the basement at a rate of 47 cubic feet of water per hour. Let f(t) represent the number of cubic feet of water that remains in the basement after t hours of pumping out water.i) Find an equation for f.ii) Find t when f(t) = 0. What does your result mean in terms of the situation?iii) What is the domain and range of the model? Explain.

Solve the system using the inverse method.
A. x = -2, y = 1 B. x = -1, y = 2 C. x = 2, y = -1 D. x = 1, y = -2
Use a graphing utility to graph the function over the indicated interval and approximate any local maxima and local minima. Determine where the function is increasing and where it is decreasing. If necessary, round answers to two decimal places.f(x) = x5 - x2; (-2, 2)

If necessary, write the equation in the standard form ax2 + bx + c = 0. Then identify the values of a, b, and c. Do not actually solve the equation.-5x2 + 7x = 8
A. a = -5, b = -8, c = 7 B. a = -5, b = 8, c = 7 C. a = -5, b = 7, c = 8 D. a = -5, b = 7, c = -8
