Naomi starts the engine on her small private airplane. The engine drives a propeller with a radius of 8 feet and its centerline

icang [17]

Answer:

5.13 feet

Step-by-step explanation:

Engine is driving the propeller with a radius of 8 feet and its centerline 13 feet above the ground.

And the speed is 700 revolutions per minute, the height of one propeller tip as a function of time is given by:

$h=13+8 \sin(700t)$

We have been asked to find the value of height, 'h', when t=4 minutes.

Plugging the value of time, 't', in the equation, we already know that we need to use degrees (not radians) we get:

$h=13+8 \sin (700 \times 4)$

$h=13+8 \sin (2800)$

$h=13+8 \times (-0.984)$

$h=13+(-7.872)$

$h=13-7.872$

$h=5.128\approx 5.13$

So the height of one propeller tip at t=4 minutes is 5.13 feet.
