<p>Could you guys help me out with these trig word problems.</p>
<p>1.As you ride a Ferris Wheel, the height that you are above the ground varies periodically. Consider the height of the center of the wheel to be the equilibrium point. A perticular wheel has a diameter of 38ft. and travels at a rate of 4 revolutions per minute.</p>
<p>A. Write an euqation to descrive the change in height, h, of the seat that was filled las before the ride began in terms of time, t, in seconds (at t=0 the seat is at the minimum height.)
b. Find the height of the seat after 22 seconds.
c. If the seat of the Ferries Wheel clears the ground by 3 feet, how long after the ride starts will the seat first be 27 ft. above the ground?</p>
<p>2.P and Q are cities on the euqtor. When the moon is directly overhead at Q it is just barely visible at P. Geometrically, this means tha MP is a tangent line to the circle. The measure of arc PQ is found by subtracting the longitude lines P and Q. arc PQ=89.07 Raius of the earth=4000 with center o. Use this information to find measure angle POQ and the distance to the moon.</p>
<p>Could you guys explain how you did them.</p>
