A smoke jumper jumps from a plane that is 18001800 ft above the ground. the function h equals negative 16 t squared plus 1800h=â16t2+1800 gives theâ jumper's height h in feet during the free fall at t seconds. a. how long is the jumper in free fall if the parachute opens at 1000â ft?
b. how long is the jumper in free fall if the parachute opens at 950950 âft?
c. what is a reasonable domain and range for the functionâ h?
a. the jumper is in free fall for nothing s if the parachute opens at 1000 ft. â(round to two decimal places asâ needed.)

step-by-step explanation:

it have the same area.brainliest

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4
