A large clock with minute hand (radius) 2 meters sits atop a clock tower 15 meters tall (as shown).

Question

Assume that at t = 0 minutes, the minute hand points to the “12.”Sketch the graph and find a function of the form  that gives the vertical distance D (cm) from the tip of the minute hand to the ground at a given time t (minutes).

Answer 1

????? 15 meters tall, du that meen top av klok is 15 meters abuv ground?

or maebee senter av klok is 15 meters up????

Me assume top av klok is 20 meters abuv ground

Then tip av minut hand is 20 meters abuv ground at time=0

minut hand radius=2 meters, so senter is up 18 meters

hand speed...2pi/60 per our=0.104719755 radians/minut

Then vertikal distans av tip av minut hand=18+2*tan(0.104719755* minuts)

me leev it tu yu tu konvert tu cm

Answer 2

make that the kotangent(...)
