Answer: B) y = (1/28)x^2</h3>
Explanation:
p = focal distance = 7
the focal distance is from the vertex to the focus
The parabola opens upward (since the vertex is below the focus) so 'a' is positive and a = 1/(4p) = 1/(4*7) = 1/28
The vertex is (h,k) = (0,0)
Put this all together into the formula below and simplify
y = a(x-h)^2 + k
y = (1/28)(x - 0)^2 + 0
y = (1/28)x^2
Standard form would be 1.46e-6 because the variable has one degree and the number 6 does not have a degree.
How to solve Problem:
10.5÷1.5
Move both decimals all the way to the right
105÷15
Then solve from there. I'll give you a hint, It's a whole number.
