Answer: 14.48000 . . . ≤ t < 15.0000
Step-by-step explanation:
"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second. That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right. For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds. The term used here. truncated, means that the digits after the hunredth place are simply dropped. It doesn't say rounded, just truncated. Brutal. So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.
So the time could actually be 14.48000 . . . ≤ t < 15.0000
Well we could look at it like this. we can make a generic equation for this by saying that the vertex lies at (0,0). we know that it is 24 inches wide. this means that on either side of the vertex is 12 inches. since it is 4 inches deep, we know that these points at x = -12, 12 have a y = 4. to make the equation we look at the vertex form of parabolas:
y=a(x−h)^2+k
we can plug in the point (-12,4) and the vertex
4 = a (-12 + 0)^2 + 0
4 = a (144)
a = 1/36
the vertex is
(h,k) or (0,0)
and the focus point :
(h,k+1/4a) or (0,0 + 1/(4/32)
(0, 1/(1/9))
(0, 9)
this would mean that the focus point is 9 inches above the vertex.
