Answer:
4 : 7
Step-by-step explanation:
No. of families = 2400
No. of cars = 4200
Family : Cars
= 2400 : 4200
= 24 : 42
= 6 x 4 : 6 x 7
= 4 : 7

So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: ![x=\frac{4}{2*2}=\frac{4}{4}=1](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B4%7D%7B2%2A2%7D%3D%5Cfrac%7B4%7D%7B4%7D%3D1%20)
y = 4x^2 + 8x + 3: ![x=\frac{-8}{2*4}=\frac{-8}{8}=-1](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B-8%7D%7B2%2A4%7D%3D%5Cfrac%7B-8%7D%7B8%7D%3D-1%20)
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
Answer:
The circumference of the horse pin is 150.86 feet
Step-by-step explanation:
In this question, we are to calculate the circumference of the horse pin, given that the diameter is 48 feet.
Mathematically, the circumference can be calculated using the formula
C = 2 * pi * r
where r = D/2 = 48/2 = 24 feet
The circumference C is thus = 2 * 22/7 * 24 = 1056/7 = 150.86 feet
