If x2 + y2 = 100 and dy/dt = 3, find dx/dt when y = 8. (enter your answers as a comma-separated list.)

Answer;

dy/dx = - or + 4 and y = 8

Explanation;

x² + y² = 100

when y = 8

Then, x² + 8² = 100

thus; x² = 100 - 64 = 36

x² = 36

therefore; x = + 6 or -6

2x (dx/dt) + 2y (dy/dt) = 0

x(dx/dt) + y (dy/dt) =0

When dy/dt = 3

= (- or + 6) dx/dt + 8 (3) = 0

thus; dx/dt = - 8 (3/6)

= + or - 4.

Answer; y = 8 and dx/dy = - or + 4

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
