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.

Answer:
Options c and d
Step-by-step explanation:
Given is a graph with period pi.
ii) The graph is discontinuous
iii) x intercepts are say (a) units to the right of y axis and repeats for every interval of pi.
Fix the function
a) y = sinx cannot be this graph because sinx is a continuous graph
b) y =cosx cannot be this graph because cosx is a continuous graph
e) y = sec x is undefined for the range (-1,1) since the given graph is defined in this interval, secx is not answer.
f)y = csc x is undefined for the range (-1,1) since the given graph is defined in this interval, cscx is not answer.
c) y=tanx is a discontinuous graph at x = odd multiples of pi/2
Hence the given graph can be of the form y =- tan (2x+a) which shows reflection over y axis,
d) y = cotx can also be this graph with adjustments for period and horizontal shift.
So answers are c and d
Answer:
24 inches.
Step-by-step explanation:
Given:
During a week the water level in a pond decreased by 4 in. Per day,
For two days, it decreased by half that amount = 
Question asked:
How much did the water level decrease in the pond in one week?
Solution:
As we know, there are 7 days in a week.
<u>For 5 days,</u>
Each day water level decreased by = 4 inches
In 5 days, water level decreased by = 
<u>For exceptional 2 days:</u>
Each day water level decreased by = 2 inches
In 2 days, water level decreased by = 
Water level decreased in whole week = 20 + 4 = 24 inches
Therefore, water level decreased 24 inches in the pond in one week.
She was driving an average of 51 mph.
