0.5 is the answer hope I helped you
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
I believe it's A, C and D.

Answer:
5 hours
Step-by-step explanation:
A motorcycle will complete the 540 mile trip in 11.25 hours
And the car will complete it 2.25 hours less, i.e 11.25 -2,25 = 9 hours.
then,
Speed of the car:
60t + 48t = 540
108t = 540
If you Divide both sides by 108 we get t = 5
So, they will meet in 5 hours,
