The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.
correct answer is 6!
(x+6)2+(y-10)2=36 , would be your equation.
Answer:
640 people
Explanation:
480 people = 75 %
x people = 100%
480 : x = 75 : 100
75 x = 48,000
x = 48,000 : 75
x = 640
