Given:
13 pounds and 7 ounces
convert to kilograms:
1 kilogram = 2.20462 pounds
1 kilogram = 35.274 ounces
13 pounds * 1 kg/2.20462 pounds = 13 kg/2.20462 = 5.8967 kg
7 ounces * 1kg/35.274 ounces = 7 kg/35.274 = 0.1984
5.8967 kg + 0.1984 = 6.0951 kg. rounded up to 6.10 kgs.
Since the focus is at (0, 2) and directrix is y = -2
point where both of these have the same x-value will be at (0, 2) for the focus and (0, -2) for the directrix.
The vertex will also have the same x-value so it will be (0, y).
y-value is half-way between the y-value of the focus, and the y-value of the directrix at x = 0.
Directrix y-value is -2 at x = 0 and for the focus it's 2 at x = 0.
Halfway between y = -2 and y = 2 is y = 0.
So the vertex of the parabola occurs at (0, 0).
So that's x^2 = 4ay = 4(2)y = 8y.
y = 1/8*x^2
hope it helps
C because all you need to do is compare the 2 variables and then add the variables and the multiply it and then divide it. Then your golden.
