How do work this out

We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35. 

Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.

So split the 2r into these two terms and group.

(5r^2 - 5r) + (7r - 7)

Factor both groups.

5r(r-1) + 7(r-1)

The factors of (r-1) can be added together to get the answer.

(r-1)(5r+7)

sum of exterior angles = 360

64  + 60 + 69 + 42 + x + x +23 = 360

2x + 258 = 360

2x = 360 - 258

What is the equation for a parabola with a focus of (0,-4) and a directrix of y=4 if the vertex is at the origin?..1)..y=1/16x2.
OlgaM077 [116]

Answer:

y = - \frac{1}{16} x²

Step-by-step explanation:

Since the vertex is at the origin and the focus at (0, - 4) then the parabola opens vertically down with equation

x² = 4py ( p is the distance from the vertex to the focus )

Here p = - 4 ( focus is below the vertex ), thus

x² = 4(- 4)y = - 16y ( divide both sides by - 16 )

y = - \frac{1}{16} x²
