Calculate the length of DE.
CaHeK987 [17]

set up the proportion, cross multiply, and solve for the missing length.

\frac{BA}{BE} = \frac{DC}{DE}

\frac{6}{3} = \frac{9}{DE}

6(DE) = 3(9)

DE = \frac{3(9)}{6} = \frac{9}{2} = 4.5

Find dy/dx x^2y=xy^2
mamaluj [8]
<span>x^2y=xy^2

Differentiate implicitly.

x^2y' + y(2x) = x(2yy') + y^2

x^2y' + 2xy = 2xyy' + y^2

x^2y' - 2xyy' = y^2 - 2xy

y'(x^2 - 2xy) = y^2 - 2xy

y' = (y^2 - 2xy)/(x^2 - 2xy)</span><span />
