Ok I have two questions both i have done but not 100% sure I have done them correct. I am good with math but not so well at Trigonemetric stuff. Ok here it is.(adsbygoogle = window.adsbygoogle || []).push({});

1) Convert the following angles to radian measure, leave in simpilest rational form. 350 degrees.

Ok what i have done is this:

350pie/180

35pie/18 radians. Is that correct and simpilest form?

2) A ferris wheel with a radius of 20m rotates once every 40 seconds. At the bottom of the ride, the passenger is 1m above the ground. a) Determine a function that represents height, h, above ground and at time t, if h=41 at t=0.

Ok so i went and drew a graph of what i think it would looks like and from it got this information. Verticle translation of 21, phase shift of 10 to the right, amplitude of 20, period is 40 which equals pie/20. So from this I got the equation to be:

h=20sinpie/20(t-10)+21

Would this be correct for that question?

The follow up question part b) is Determine the passenger's height above the ground after 15 seconds. So i just took 15 and put it into my equation as t and got an answer of 35.142m. Did I do this correct and get the correct answer? Thank you very much it is much appreciated.
