3. An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. Assume the plane continues at the same rate of descent. The plane’s height and minutes above the ground are related to each other. A. Write an equation to model the situation.
B. Find the altitude of the plane after 5 minutes.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
