Answer:
Vertex.
Step-by-step explanation:
An angle can be defined as a figure formed by two rays with a common endpoint. The two rays are called the sides of the angle. The common endpoint is called the vertex.
Answer:
a) -6
b) 9
c) 27
Step-by-step explanation:

Ok to find dy/dx of x+2y=xy we take derivative of both sides with respect to x
1+2dy/dx = x*dy/dx +y*dx/dx
1+ 2dy/dx = x*dy/dx + y* 1
2dy/dx +1 = x*dy/dx + y
2y’ + 1 = xy’ + y
2y’ + 1 - xy’ = y
2y’ -xy’ = y - 1
y’(2-x) = y - 1
so we get finally
y’= (y-1)/(2-x)
Hope this helps you understand the concept! Any questions please ask! Thank you so much!!
The point on the unit circle corresponding to -180 degrees is
((x, y) = (-1, 0).
<span>tan(-180°) = y/x = 0/(-1) = 0</span>
0.0094% error
Divide 150/141. You get 0.94, then you need to find the percentage of that by clicking the percent button of your calculator
