Answer: (y - 9)^2 = -48(x - 7)
Step-by-step explanation:
To find the equation of the parabola in standard form, we can use the formula (y - k)^2 = 4p(x - h), where (h, k) is the vertex and p is the distance between the vertex and the focus.
Given that the vertex is (7, 9) and the focus is (-5, 9), we can see that the vertex and focus have the same y-coordinate, which means the parabola opens horizontally.
The vertex is (h, k) = (7, 9) and the focus is (h + p, k) = (-5, 9). By comparing the x-coordinates, we can find p.
-5 = 7 + p
p = -12
Substituting the values into the formula, we get:
(y - 9)^2 = 4(-12)(x - 7)
So, the equation of the parabola in standard form is (y - 9)^2 = -48(x - 7).

c. Never
i would assume 9.6 kph
b) x (2x^2 + 4x + 1)
c) 2x (x^2 + 2x - 1)
d) x (2x^2 + 4x -1)
Answer:
50 degrees
Step-by-step explanation:
Since this is an isosceles triangle, and the measurements on the left and right are the same, that means that both angle measurements on the bottom are the same.
180 - 80 = 100
100/2 = 50
