Answer:
The lesser number of workbooks are 1,000
Step-by-step explanation:
The correct question is
The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?
we have
For 
substitute in the equation and solve for b
Remember that the profit and the number of workbooks is in thousands
so
P=5
Using a graphing tool
Solve the cubic function
The solutions are
x=-1
x=1
x=5
therefore
The lesser number of workbooks are 1,000
<u><em>Verify</em></u>
For b=1
-----> is in thousands
so
----> is ok

Answer: 40
Step-by-step explanation:
16 + 24
= 8(2) + 8(3)
= 8(2 + 3)
= 8(5)
=40
Answer:
The linear equation modeling the given function is P(t)=1700t+45000.
Step-by-step explanation:
In the question it is given that a town's population has been growing linearly. In 2003, the population was 45000, and the population has been growing by 1700 people each year.
It is required to write an equation P(t), for the population t years after 2003.
To solve this question, substitute the given slope , or change in population in the equation with the initial population . Thus, formulate the equation modeling the given function.
Step 1 of 1
Formulate the equation in the slope-intercept form.
Answer:
2x + 5
Step-by-step explanation:
Let x represent the number
Twice the number will be represented by 2x, since that multiplies the number by 2
Then, add 5 to this:
2x + 5
So, 2x + 5 is the expression that will represent this situation
