If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the y-axis, it has an equation of (x - h)^2<span> = 4p(y - k)</span><span>, where the </span>focus<span> is (h, k+p) and the </span>directrix<span> is y = k - p. So, we need to determine the values from the equation.
</span><span>y=1/28(x-4)^2-5
</span>(x-4)^2 = 28(y+5)<span>
(h,k) = (4, -5)
p = 7
focus= </span>(h, k+p) = 4,2
directrix = y = k - p = -12
Hope this answers the question.
Well from what I understand about the question, it's asking if there only needs to be 1, how many can there be. so 9
-4/5 + (-1/4) =
-4/5 - 1/4 = (common denominator is 20)
-16/20 - 5/20 =
-21/20 or - 1 1/20 <=== ur answer
Answer:
This is an impossible question. This is because it is less than -80 but when you add the 5 it is -70 therefore it must be -75. But it saying it is below -80 therefore this is an impossible question
Plug in 3 for h and 27 for g. Then multiply 2 and 27 which equal 54 then subtract by 3. remember 3 is smaller than 54 so it turns into a negative so its -51
