Find the rate of change of total revenue, cost, and profit with respect to time. Assume that R(x) and C(x) are in dollars.
R(x)= 2x, C(x)= 0.01x² + 0.4x + 30, when x=25 and dx/dt=7 units per day.
1. Find the rate of change of total revenue per day.
2. Find the rate of change of total cost per day.
3. Find the rate of change of total profit per day.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?

What does the relationship between the mean and median reveal about the shape of the data

Which inequality statement describes the two numbers on a number line? "? 7 and a number 5 units to the right of ? 7"
