Answer:
3/4
Step-by-step explanation:
3/4 = .75
4/10 = .40
2/5 = .40
1/3 = .33
Factor it out (x+2)(x-1)
Set each of these equal to zero to get -2,1 as your answers
The distance between the focus and directrix is, in this case, 8. Since the directrix is at x= something, the parabola opens sideways, and since the directrix is on the left, to the right. In which case, y^2=p(x), where p is 4 times distance of half of distance between directrix and focus, so the answer is y^2=16x
Yes. The triangles are both right triangles, which means they both have a single right angle.
Vertical angles are congruent (equal), and the angles below are vertical angles.
x + 40 = 3x
40 = 3x - x
2x = 40
<u><em>x = 20</em></u>
