Match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y = - 9.25. 1.
Choose a point on the parabola.
2.
Write the equation of the parabola.
3. Use (x, y).
Square both sides and simplify.
4.
Find the distance from the focus to the point on the parabola.
5.
Set the distance from focus to the point equal to the distance from directrix to the point.
6.
Find the distance from the point on the parabola to the directrix.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
