Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
Out of 170 students in 12th grade, 27+23 = 50 students have more than 1 college in mind.
So 50/170, or 29% is your answer.
There's nothing more you can say about it besides exactly
what you have already said, until you know the value of 't'.
