Answer:
45. You need to multiply the exponents by one to one. Then you got your answer.
Step-by-step explanation:
I got it correct
<2 = 45 degrees They are corresponding angles
74 + <1 + <2 = 180 it makes a straight line
74 +<1 +45 = 180
119 +<1 =180
subtract 119
<1 = 180 -119
<1 = 61 degrees
For
(x-h)^2=4p(y-k)
vertex is (h,k)
distance from vertex to directix=p=distance from vertex to focus
|4p|=focal width
remember, focus is on the side of the parabola where it opens and directix is at the back
when p is negative, it opens down
when p is positive, it opens up
look at equation
-1/40(x-0)^2=(y-0)
times -40 to both sides
(x-0)^2=-40(y-0)
(x-0)^2=4(-10)(y-0)
vertex=(0,0)
p=-10,it's negative so it opens down
focus is 10 units below vertex (y direction)
focus=(0,-10)
diretix is 10 above
directix is y=10
focal width=|4p|=|4(-10)|=|-40|=40
vertex=(0,0)
focus=(0,-10)
directix is y=10
focal width=40 units
Answer:
it is b because I did the problem yes it is b
