7 + 9 *6
7 + 54
61 - final answer
If we take 28 to be the 100%, what is 21 off of it?
Answer:
180-142=38 for the acute angle next to the entry
90+38=128
180-128=52
a=52
The answers to the various part as well as its reasons are given below
<h3 /><h3>Part A:</h3>
- The x-intercepts shows a zero profit.
- The maximum value of the graph tells or depict the maximum profit.
- The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
- This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
- The profits are negative as seen on the left of the first zero and on the right of the second zero.
<h3>Part B:</h3>
An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from 3 to 5.
<h3>Part C:</h3>
Based on the above, the domain is one that is held back or constrained by x = 0 .
We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.
