(x-h)^2=4p(y-k)
we know it is this one because the directix is y=something and not x=something
(h,k) is the vertex
p is the distance from the vertex to the focus
it is 1/2 the distance from the vertex to the directix
if p is positive, the focus is above the vertex
if p is negative, the focus is below the vertex
we have
focus is (6,2) and directix is y=1
distance from (6,2) to y=1 is the distance from 2 to 1 which is 1
1/2=p
since 1<2, we see that the focus is above the vertex (when the focus is greater than the directix, then the graph opens to the right or up)
p=1/2
1/2 below (6,2) is (6,1.5)
vertex is (6,1.5)
p=1/2
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5)
(x-6)^2=2y-3
2y=(x-6)^2+3
divide both sides by 2
y=1/2 times (x-6)^2+3/2
f(x)=1/2 times (x-6)^2+3/2
2nd option is answer
Answer:
Number with 1 dog, number with 3, and number with 4 are all incorrectly plotted.
The easiest way to find slope is to do rise/run. In this case, you rise from point (0,-3), and 'run' to point (-2,-2). The slope would be -1/2 because you are 'running' to the left, which is negative.
20% of $500 = 100$ so we take off 100.
And we take off $50 because it was out of the box and slightly scratched.
So result is $500 - $100 = $400
$400-$50 = $350
Answer = $350
Equation:
Let’s say
500=X
100=Y
50=Z
And answer = A
A=X-(Y-Z)
I hope this will be helpful
