Answer:
Supply will decrease at the rate of 29 CDs per week.
Step-by-step explanation:
The number of retro portable CD players prepared to supply to a retail outlet every week is represented by the formula
q = 0.1p² + 9p
Here p = price offered
price it offers decreases at a rate of $1 per week.
In other words,
Now we differentiate the given equation
Since,
For p = 100,
= (-1)[20+9]
= -29
Therefore,
Supply will decrease at the rate the rate of 29 CDs per week.
Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.
To graph this , first we make the absolute function alone
|x + 1| + 2 > 5
to make absolute function alone we subtract 2 from both sides
|x + 1| > 3
x+1 inside the absolute function . so x=-1
From -1, move 3 units to the right and 3 units to the left.
For x>2 , shade the graph to the right
For x< -4, shade the graph to the left
The graph is attached below
The solution to the inequality is x<-4 and x>2
