Answer:
A. p = $17.95n - $1,250.00
Step-by-step explanation:
Profit (p) = net revenue - expenditure
Net revenue = charge for transfer of n videos - expense for n blank DVD
charge per video transfer = $20.40
charge for n video transfer = $20.40 × n = $20.40n
expense per blank DVD = $2.45
expense for n blank DVD = $2.45 × n = $2.45n
Net revenue = $20.40n - $2.45n = $17.95n
expenditure = $1,250.00
Therefore, p = $17.95n - $1,250.00
Answer:
<u>BC = 3.1666</u>
Step-by-step explanation:
To solve this you need to know that cosine∅ = adjacent/hypotenuse. We already know that hypotenuse = 5 and that ∅ = 70*. By substituting these in you will get cosine 70* = adjacent/5. Evaluate cosine 70* on the calculator and get 0.633... Multiply both sides by 5 and get adjacent is about equal to 3.1666. Because BC is the adjacent side of the triangle, this is the length of BC.
