49.Redwood Growth The growth, f(x),in inches per year of a redwood tree less than 30 years old is given by the function f(x)=−0.02x2 2+x+1, where x represents the number of inches of rainfall per year.

1. Determine the growth per year of a redwood tree in a year in which there is 12 inches of rainfall.
2. If the growth of a redwood tree in one year is 10 inches, determine the number of inches of rainfall for that year (round your answer to 2 decimal places).

51. Oil Leak A tractor has an oil leak. The amount of oil, L(t),in milliliters per hour that leaks out is a function of the tractor's operating temperature, t, in degrees Celsius. The function is L(t)=0.0004t2+0.16t+20, 100°C ≤ t ≤ 160°C

1. How many milliliters of oil will leak out in 1 hour if the operating temperature of the tractor is 100°C?
2. If oil is leaking out at 53 milliliters per hour, what is the operating temperature of the tractor?
