Find CD
This question is represented with the attached triangle
To solve CD, we make use of tan formula.
Substitute 12 for DE
Make CD the subject
--- approximated
Would it just be +7.50 and +4.50 and -3.50 and -6
The function of x is 
.
<u>SOLUTION:</u>
Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).
Now, let the linear function be 
Then, function of -4 = 
And, function of 6 = 
On equating (1) and (2) to find the value of a,
On grouping the common terms,
On substituting the value of (3) in (1) we get,
So, the function of x = 
Answer:
I must sell more than 318 copies so my revenue is greater than my costs
Step-by-step explanation:
The cost function (C(x)) is divided in two: fixed costs and variable costs. In this case, we have both, the fixed costs are $3,500 that I will spent on advertising and the variable cost is the print cost that depends on the number of books i want to print. The cost function is:
C(x)= $3,500+$4x
The revenue function depends on the number of books I sell:
R(x)= $15x
If i want to know how many books I should sell to have a greater revenue than cost i must solve this inequality:
Revenue (R(x))>Cost (C(x))
$15x>$3,500+$4x
$15x-$4x>$3,500
$11x>$3,500
x>$3,500/$11
x> 318,18
I must sell more than 318 copies so my revenue is greater than my costs
