A submarine is diving toward the bottom of the ocean. The depth of the submarine, D, in feet below sea level, after t minutes have elapsed is given by the function D(t) 20+16t. The pressure, P, in pounds per square inch, exerted on the submarine at a depth of z feet is given by the function P(z) 14.7+0.445r Find an explicit expression that models the pressure exerted on the submarine as a function of the elapsed time, t, in minutes.

.

Step-by-step explanation:

The function gives the depth as a function of time, and gives the pressured exerted as a function of depth; therefore, the pressure exerted as a function of time will be modeled by the function or

Since ,

Therefore,

P(t) = 23.6 + 7.12t

answer: she must produce at least 9,000 windows in order to make a profit of $48,000

explanation:

48,000 - 12,000 = 36,000

36,000/4 = 9,000
