Larry gave out 120 caps. He gave away 15 caps per 8 people so to get the total you would multiply the 2 together.
We know that
the equation of the parabola is of the form
y=ax²+bx+c
in this problem
y=−1/4x²<span>−x+3
where
a=-1/4
b=-1
c=3
</span><span> the coordinates of the focus are
</span>
(-b/2a,(1-D)/4a)
where
D is the discriminant b²-4ac
D=(-1)²-4*(-1/4)*3-----> D=1+3---> D=4
therefore
x coordinate of the focus
-b/2a----> 1/[2*(-1/4)]----> -2
y coordinate of the focus
(1-D)/4a------> (1-4)/(-4/4)---> 3
the coordinates of the focus are
(-2,3)
48 + 2x = 180
- 48 - 48

x = 66
Answer:
968 km/h
Step-by-step explanation:
We'll use the formula 
Thus
(km/h) (to nearest whole number)
