The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
Answer: the answer is 45.5, which the second bubble down.
Step-by-step explanation:
Answer:
The number of units in the length of the shortest side of the triangle is 6.325 units or 2 sqrt 10.
Slope = 1/2 :)
rise over run (rise/run)
so... 2/4 = 1/2
hope this helps!
