Please Help!! An arrow was tossed in the air with the initial velocity of 15in/sec from a height of 5ft. Which of the following equations represents the arrows height (h), in feet over time (t), in seconds?
A) h = -4.9t² + 15t + 60
B) h = -14t + 60
C) h = -16t + 5
D) h = -16t + 1.25t + 5

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
