3 A skydiver is 760 meters above the ground when he opens his parachute. After opening the parachute, he
descends at a constant speed of 17 meters per second.
Part A: What type of function would best model this situation? Explain your answer.
Part B: Write the equation that models this situation
Part C: Sketch the graph that models the function.
Part D: Write an equation that would represent the
number of seconds it took the skydiver to reach a
height of 400 meters and use the equation to solve for
that time.
Part E: What is an appropriate domain for the
situation
A OSX 44.7
B. 0 Cosy s 44.7
D. Osy s 760

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

answer: 4

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
