To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8
k=-1/8
Answer:
y intercept (0, 4)
x intercept (4, 0)
I hope this is good enough:
216 ft per minute or 3.6 ft per second
515 divided by 216 is 2.38
it takes 2.38 minutes for the specified ant to crawl 515 feet
None of the offered choices is correct.
The correct equation is
.. a = (2s -2ut)/t^2 . . . . . . . . parentheses are required
It looks correct to me :)
