Answer:
Step-by-step explanation:
eq. of directrix is y-1=0
let (x,y) be any point the parabola.
then\sqrt{ (x-6)^2+(y-2)^2}=\frac{y-1}{(-1)*2}
squaring
x²-12x+36+y²-4y+4=y²-2y+1
x²-12 x+40-1=4y-2y
2y=x²-12x+39=x²-12x+36+3
(x-6)²=2y-3
Answer:
4 ft
Step-by-step explanation:
just look at the length of the slide and substract it.
10-6=4
The slope is -3 and the y-intercept is -1
It is 7
2 below the zero, 12 above = 14 steps
middle point is 7
7.6 is greater<span> than 55 squared</span>
