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?

step-by-step explanation:

good luck tho

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
