Answer:
6
Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6
It would be = -3.81 * 10^-3

I hope this helps ^^
Good luck
The correct answer is B because after you simplifiy the expression, you would get that answer:
7x + 3y - 2 + 6x + 1 + y^2
combine all the like terms to one side first
7x + 6x - 2 + 1 + y^2
then simplify
13x - 1 + y^2 or y^2 + 3y + 13x - 1
Answer:

Step-by-step explanation:
Given that,
The radius of circle, r = 50 feet
The central angle, 
We need to find the area of the sector of a circle. The formula for the area of sector is given by :

So, the area f the sector of the circle is
