A buoy oscillates in simple harmonic motion y=A cos wt
aswaves move past it. The buoy moves a total of 3.5 feet (vertically) from its low point to its high point. It returns to its high point every 10 seconds.

a.) write an equation describing the motion of the bouyif its is at its high point at t=0

b) determine the velocity of the buoy as a function of t


Any help would be greatly apreciated or a formular. Thanks

Molly flies a kite that is attached to a string that is 100 meters long. The angle of elevation of the kite is 36 degrees. If she is holding the string 1 meter above the ground, how high is the kite?

COuld you guys describe to me, or make it someone if possible how the diagram of the right angle triangle would look like. I don't understand the 1m part, it throws me off.

10---- Find, in radical form, the distance between the points (-3,7) and (4,2)



12--- 4x^2-9 * 4x-8 Simplify (the line thing I made is division)
______ _____
2x^2-x-6 2x+4

13---- Solve the following system of equasions graphically and check

y=x^2-8x+10

y=x-8

Is this the kind where you graph each seperatley then get the point where they cross? and i know how to graph the second one but can you put the 1st on in y=mx for or whatever you need to solve it

Thank you very very much!

TRUE OR FALSE if false explain why
1. if graph of function has 3 x-intercepts, yhen it must have atleast 2 points at which its tangent line is horzontal.

2. If graph of a polynomial function has 3 x-intercepts then it must have atleast 2 points at which tangent line is horizontal

3. If a function is continuous on closed interval, then it must have a minimum on the interval.

4. every nth-degree polynomial has (n-1) crtical numbers

5.An nth-degree polynomial has at most (n-1) critical numbers
