Answer:
20 quarts of peanut oil worth 19 cents a quart must be mixed.
Step-by-step explanation:
The midline is a horizontal axis that is used as the reference line about which the graph of a periodic function oscillates.
More About MidlineThe equation of the midline of periodic function is the average of the maximum and minimum values of the functionExamples of Midline<span>Figure-1 shows y = sin x and Figure-2 shows y = sin x + 1. The second curve is the first curve shifted vertically up by one unit.
The midline of y = sin x is the x-axis and the midline of y = sin x + 1 is the line y = 1.</span>

Step-by-step explanation:
Reduce the expression, if possible by cancelling the common factors.
Answer: D i just did it
Step-by-step explanation:
The data is larger for intermediate values of x, so the parabola opens downward. That leaves only the 2nd and 4th choices, where the x² coefficient is negative.
To determine which of those is appropriate, it is only necessary to consider x=1. The 2nd choice will give a y-value near 100; the 4th choice will give a y-value near 250.
The fourth choice is appropriate:
... y = -9.16x² +73.04x +183.3
_____
Alternatively, you can consider that for the x-coordinate of the vertex to be positive (it's about +4), the coefficients of the x² and x terms must have opposite signs. Using this consideration, you don't even need to evaluate the expression to determine that the 4th choice is the correct one.
