N=1/5 I think i had this question before.
Answer:
Step-by-step explanation:
y=x²+7
vertex(0,7)
the length of latus rectum in a parabola equal to four times the focal length :
y=x²+7
focus X=-b/2a=0
focus Y=c- (b²-1)/4a=7+1/4=29/4
focus (0 , 29/4)
latus rectum is 29/4
(x-h)^2 = 4p (y-k) 4p is the length of the latus rectum with vertex(0,7)
(0-0)²=4p(29/4-7)
0=29p-28p=1p
the length of the latus rectum is 1
Answer: you are correct the correct answer is A
Answer:
1/2
Step-by-step explanation:
The scale factor is 1/2 because each side length of
is 1/2 of the length of the side lengths of
.
Hope this helps :)
You

It is 9200
Just to be sure, substitute with x = 2 in the equation.
