The two lines are tangent to the circle at points that are 180 degrees apart.
2 ( x - 4) is the answer if that is shown out of the selections you can make.
Since both p and q are true, ~p → q means F → T. This matches only the 4th selection, which (rightly) declares the implication to be true.
T F → T
55hours times .17 will give you the answer.
Sarah spends 9.35hours on air.
This will be a parabola which opens upwards. and with a vertex at ( (-8, (-1-1.5) = (-8, -2.5). (The vertex is halfway between the focus and the directrix).
The general form is (x-h)^2 = 4p(y - k) where (h,k) is the vertex.
So we can write the equation as
(x + 8)^2 = 4p(y + 2.5)
p = 1.5 so we have
(x + 8)^2 = 6(y + 2.5)
x^2 + 16x + 64 = 6y + 15
6y = x^2 + 16x + 49
y = (1/6) x^2 + (8/3)x + (49/6) is the answer
