Answer:
two and one third + 2x ≥ 4
Step-by-step explanation:
From the information given:
The number of hours Nicole already practiced with =
However, she wants to further her practice for 2 days and make sure that each day equal each other
Let consider y be the hours she practiced each day
Then, the number of hours she will practice in two days will be 2y
Thus, the total number of hours she practiced can be computed as
=
Suppose Nicole desire to practiced for at least 4 hours,
Then,
Therefore, the required inequality to determine the minimum number of hours she needs to practice on each of the 2 days suppose she practiced for at least 4 hours a day is:
two and one third + 2x ≥ 4 i.e.
We need to find a cosine function:
The amplitude represents half the distance between the maximum and minimum values of the function and the period goes from the x-value of one peak to the x-value of the next one. Therefore:
Finally:
And y(4) is:
