Suppose a parallelogram has sides of length 4 and 8 and the height to the shorter base is 6. What is the height to the longer base?

I got an answer to this problem but I don't think it is right, the answer I got was the square root of 52.

Does anyone have a better answer?

THANKS!

The equation of a curve is x^3 + 2y = 3xy

dy/dx = (y -x^2) / ( 2y^2 - x)

^ means to the power of.

Find the coordinates of the point, other than the origin, where the curve has a tangent which is parallel to the x-axis.

Thanks a lot in advance

For each positive interger n, define R(n) to be number of regions into which n lines, no two are parallel and no three of which intersect at the same point, divide the line.

Determine a forumla for R(n) and prove by induction it is true for all positive n integers...

I got a couple formulas but I don't know how to do the induction part...it's like...r(n) = n(n+1)/2 + 1 or r(n) = r(n-1) + n or r(n+1) = r(n) + n + 1...

which one do I use? how do I do the induction? thanks

I misinterpreted a simple equation, leading me to think of powers(exponents) that are not whole numbers. 2(2)(2)=8.
2(2)(2)(1)=8. So does the .5 mean nothing? Or mean nothing just in this case?
