a(t)= t^2/2 - 20t + k

There was a 50-day period when the number of ants in a certain hill could be modeled by the function “a” above. In the function, “k” is a constant and a(t) represents the number of ants on day number “t” for 0 ≤t ≤49. On what day was the number of ants in the hill the same as it was in day 10?

answer: a

step-by-step explanation:

the answer is 11.2 (i know i’m late)

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
