The bases of trapezoid ABCD are AB and CD. Let P be the intersection of diagonals AC and BD. If the areas of triangles ABP and CDP are 8 and 18, respectively, then find the area of trapezoid ABCD.

Solution 1: Triangles ADE and BFE are similar since \overline{AD}\parallel\overline{BF}. Furthermore, the ratio of their areas is 9:1, so AE/BE = 3. Then CD = AB = AE + BE = 3BE + BE = 4BE. Triangles FEB and FDC are similar, so the area of triangle FDC is (DC/BE)^2 \cdot [FEB...

Find a number x0 between 0 and pi such that the tangent line to the curve y = sin x at x = x0 is parallel to the line y = -x=2. I get that for both lines to be parallel to each other their slopes need to be the same. I found -1/2 = cos(x) but I get stuck here. What ...

So y'(0) = 0 because there is a horizontal tangent at x = 0?

Find a function f such that the curve y = f(x) satisfies y'' = 12x, passes through the point (0,1), and has a horizontal tangent there. I can use the anti-derivatives to get y = 2x^3 + Cx + D but I don't know how to get C even though I know D = 1.

Concerning my past question, is "working" the only word in the gerund phrase and my teacher said that it "working" wasn't a DO. No one in my class could figure out the answer.

**Study Tips**

Sit in your own quiet place without any noise. If you don't get distracted, you can listen to soft music which helps calm your nerves or tension. Scientists also prescribe lighting a mint smelling candle or something that smells minty to help stimulate your mind.
