A window cleaner is 100ft off the ground and drops a squeegee, using the formula below, when will the squeegee hit the ground? Round the answer to the nearest tenth of a second.
h = - 16t? + 100
The squeegee will hit the ground after
seconds. (round to a tenth of a second)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

im with everythinglos so yeahhhhh
