We know that
sector c is 35% of the total area of the circle
if 360°----------> represent the 100% of the circle
x-------------> 35%
x=35*360/100----> x=126°
the answer is
the central angle for sector c is 126°
B is your answer have a nice day and sorry it took this long to get an answer :)
P(x) = R(x) - C(x) Breaking even is the point where revenue starts to overtake cost. It is, therefore, the point where P(x) = 0. Since these are all linear functions, you know that after that point the business is profitable. P(x) = 0R(x) - C(x) = 015000x - (9000x+72000) = 015000x - 9000x - 72000 = 06000x - 72000 = 06000x = 72000x = 72000/6000x = 12 At 12 units the business breaks even.
Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
The value of x is more 90 because the angle is an obtuse and an obtuse is more than 90 degrees.
