The velocity v (in meters per second) of an object that is thrown straight upward with an initial velocity v, is given by v = v. - 9.8t, where t represents time in seconds. If a ball is thrown upward at 30 meters per second, when will its velocity drop to 5 meters per second? Round to the nearest tenth of a second.​

Someone answer asap for ! 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
