Suppose you have 54 feet of fencing to enclose a rectangular dog pen. The function A = 27x - x^2, where x = width, gives you the area of the dog pen in square feet. What width gives you the maxium area? What is the maxium area? Round to the nearest tenth as necessary.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

Write an equation for the function that includes the points (1,4/5) and (2,2/3)
