Your missing value would be 47
Answer:
D
Step-by-step explanation:
a sqrt 2 = 5
a = 5 / (sqrt 2)
a=5sqrt2 / 2
We are given with the data of a parabola with vertex at (2, 2) and directrix at <span>y = 2.5. the formua should be ax^2 + b x + c = y because of the directrix.
(x-h)^2 = 4a (y-k)
(x-2)^2 =4a (y-2)
a is the equidistant distance from focus to vertex and from vertex to directrix that is equal to -0.5
then the answer is
</span>(x-2)^2 =-0.5*4 (y-2)
<span>x2 - 4x + 4 = -2y +4
x2-4x+2y = 0
answer is C

X=7 because if an angle is bisected it is divided into two equal part so both sides must equal twenty five so you replace seven for X and you have 5(7)-10 you do the math five times seven equals thirty five minus ten is twenty five.
