Distance from focus to vertex=distance from vertex to directix
from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)
for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix
vertex=(6,1.5)
ditance=0.5
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5
Answer:
You need to show a graph so we can calculate the problem.
Step-by-step explanation:
Answer:
660
Step-by-step explanation:
Let A = number of buttons in Box A
and B = number of buttons in Box B
We have two conditions:
(1) A + B = 1200
(2) B + 360 = 3(A – 360) Remove parentheses
B + 360 = 3A - 1080 Subtract 360 from each side
(3) B = 3A - 1440 Substitute (3) into (1)
A + 3A - 1440 = 1200 Combine like terms
4A - 1440 = 1200 Add 1440 to each side
4A = 2640 Divide each side by 4
A = 660
