The function y = -16t^2 + 40 represents the height y (in feet) of a water
droplet t seconds after falling from an icicle.

a. After how many seconds does the water droplet hit the ground? Round
your answer to two decimal places.

b. A second water droplet falls from a height of 22 feet. Which water droplet
hits the ground in the least amount of time?

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

answer:

idk

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

might be the correct answer will be question number 2
