Solve ax + by + c = o for y

1 answer:

8 0

$ax+by=o\ \ \ \ \ \ \ |subtract\ ax\ from\ both\ sides\\\\by=o-ax\ \ \ \ \ \ |divide\ both\ sides\ by\ b\\\\\boxed{y=\frac{o-ax}{b}}$

As you can see in the given figure, there are two intersecting chords inside the circle.

Recall that the "Intersecting Chords Theorem" is given by

$AE\cdot EC=BE\cdot DE$

For the given case, we have

AE = 7

BE = 6

EC = 9

Let us substitute these values into the above equation and solve for DE

$\begin{gathered} AE\cdot EC=BE\cdot DE \\ 7\cdot9=6\cdot DE \\ 63=6\cdot DE \\ \frac{63}{6}=DE \\ 10.5=DE \\ DE=10.5 \end{gathered}$

Therefore, the length of DE is 10.5 units.

V=hpr^2, r=d/2 so

V=(hpd^2)/4

h=(4V)/(pd^2) ft given that d=4 and V=527.8
