Answer:
32,624,500
Step-by-step explanation:
Implicit differentiation
take the deritivive with respect to x
first
y+2=(1/2)(x^2)-2sin(y)
take deritivitive
dy/dx+0=1/2(2x)-2(cosy)dy/dx
dy/dx=x-2cosy(dy/dx)
add 2cosy(dy/dx) to both sides
dy/dx+2cosy(dy/dx) =x
undistribute dy/dx
dy/dx(1+2cos(y))=x
divide both sides by 1+2cos(y)

at (2,0)
x=2
y=0




the slope is 2/3
Stacy asked Jenny to borrow 3.50 dollars to buy some fruit, putting Stacy’s balance at -3.50. Ally asked John for 1.50 to buy a donut, putting Ally’s balance at -1.50. Both girls found 10 dollars each on the floor, who has more money, Ally or Stacy?

Answer:

Step-by-step explanation:
Consider the trapezoid ABCD. In this trapezoid BC=a and AD=b.
Since triangles BOC and AOD are somilar, then

Triangles OAE and CAB are similar, then

This means that

Similarly, from similar triangles FDO and CDB:

Thus,
