.
Step-by-step explanation:
Sophia expects the number of cows, C, on her farm t years from now to be modeled by the function:

Additionally, she expects the supply of hay, F, in tons, that her crops can provide for each cow t years from now to be modeled by the function

Let H be the total yearly amount of hay produced in Sophia's farm (in tons) t years from now.
Total amount of Hay produced in sophia's farm= Number of cows in farm×Amount of hay required for each cow.
i.e. H(t)=C(t)×F(t)

and we know that 
Hence,
.
Hence, the hay produced on Sophia's farm is used exclusively to feed her cows i.e. we need to write the formula of H ( t ) in terms of C(t) and F (t) is:
.
I’m going to say A.yes but I’m not sure sorry.
Answer:
12 o'clock.
Step-by-step explanation:
As we are talking time we work in mod 12.
9 mod12 + 111 mod12
= (9 + 111) mod12
= 120 mod 12
= 0.
So the time will be 12 o'clock.
