An object is thrown upward from the top of a 112 foot building with an initial velocity of 96 feet per second. the height h of the object after t seconds is given by the quadratic equation h=-16t + 96t + 112. when will the object hit the ground ?

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

What is the value of n in the equation -1/2(2n+4)+6=-9+4(2n+1)

Me i'm timed right now! a. (0,-5)b. (0,-3)c. (0,3) d. (0,5)
