The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:
Rewriting we have:
From here, we clear x:
Then, the amount of Soybean meal is:
The amount of cornmeal is:
Answer:
cornmeal: 280 lb
Soybean: 40 lb.

Answer:
Step-by-step explanation:
Recall that a cosine function of the form has the following:
- amplitude A
- Frequeny .
- Phase shift
- Midline D
So, in our case, we know that A=3, (which implies that
) and D=5. Since we are not said everything about the Phase shift, lets asumme that the Phase shift is 0. Hence C=0.
Then, our desired function is
