Answer:
x^2 + y^2 = 100
Step-by-step explanation:
The standard form equation for a circle is:
(x – h)^2 + (y – k)^2 = r^2
Where h is the x coordinate of the center point and k is the y coordinate of the center point. Since the center point is (0,0), this simplifies to:
x^2 + y^2 = r^2
Since the radius is 10, this simplifies to:
x^2 + y^2 = 100
I think the answer is 60.
5 toppings multiply 3 sizes is 15, multiply types of crust equals 60
5p + 2,000,000 = 22,500,000
5p = 20,500,000
p = 20,500,000/5
p = 4,100,000 population in 1950
The answer is D, dilation by a scale factor of 2 followed by reflection about the y- axis.
Answer:
2x² + x - 1 = 0
a= 2 b= 1 c= -1
x = [ -b +- sqr rt( b^2 -4ac) ] / 2*a
x = -1 +- sqr rt (1 - 4 *2*-1) / 4
x1 = [ -1 + (sqr rt (1 +8)) / 4
x1 = ( -1 + sqr rt (9)) / 4
x1 = (-1 + 3) / 4
x1 = .5
x2 = (-1 -3) / 4
x2 = -4 / 4
x2 = -1
