a glider begins its flight 3/4 mile above the ground. After 20 minutes, it is 1/2 mile above the ground. Find the change in height of the glider. If it continues to descend at this rate, how long does the entire descent last?

Volume of a cylinder with a radius of 13 in and height of 30 in

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
