A ball is thrown from an intial height of 5 feet with an intial upward velocity of 17 ft/s. The ball's height h in feet after t seconds is given by the following. h=5+17t-16t^2

Find all values of t for which the ball's height is 9 feet.
Round your answer(s) to the nearest hundredth.

-16t²+17t+7=11

==>16t²-17t+4=0

Δ=17²-4*4*16=33

==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)

or t=(17+√33)/32=0.710767 (s)≈0.71 (s)

Step-by-step explanation:

plz give brainliest

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
