Homework Statement
I've got the equation of a parabola y=2x^2-4x+1 with point (-1,7) and a tangent line running through it the point. I'm supposed to find the equation of the line. Simultaneously solve this equation with that of the parabola, place the results in form ax^2+bx+c, and find the...
Thank you, turns out I was on the right track. Here's what I did.
-23=100sin(.1879474972t-π/2)
-.23=sin.1879474972t-π/2
-.2320776829=.1879474972t-π/2
t=7.123
Now the problem is I'm not sure how to find the second time.

A Ferris wheel of radius 100 feet is rotating at a constant angular speed ω rad/sec counterclockwise. Using a stopwatch, the rider finds it takes 5 seconds to go from the lowest point on the ride to a point Q, which is level with the top of a 44 ft pole. Assume the lowest...
Hi everyone, thank you for the input. Let me clarify my situation, I uploaded a diagram; the approach I had been working on was the one Mandelbroth had mentioned. I had y = mx-m3+2 and y^2 + x^2 = 1, when I plugged the first equation into the second I wasn't sure what to do especially because...
