A waterfall has a height of 1500 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 20 feet per second. The height, h, of the pebble after t seconds is given by the equation h = -16t^2 + 20t +1500. How long after the pebble is thrown will it hit the ground? The pebble will hit the ground about [___] seconds after it is thrown.

(Simplify your answer. Round to one decimal place as needed.)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
