(x-h)^2=4p(y-k)
vertex is (h,k)
p is the distance from focus to vertex and distance from vertex to directix (vertex is in middle of directix and focus)
if p is positive, the parabola opens up and the focus is above the directix
if p is negative, the parabola opens down and the focus is below the directix
we see the directix is over the focus (1>-1) so the parabola opens down and p is negative
distance from (5,-1) to y=1 is 2 units
2/2=1
p=-1 since p is negative
1 up from (5,-1) is (5,0)
veretx is (5,0)
(x-5)^2=4(-1)(y-0)
(x-5)^2=-4y is the equation

Option D
Answer:
4x^5−15x^3−11x−1
Step-by-step explanation:
Simplify the expression. 4x^5−15x^3−11x−1
Turn 45% into a decimal. You get 0.45, because you move the decimal two places to the left.
Then multiply 300*0.45
You get 135
