Which equation would you use to find how high the bird is flying

lisov135 [29]

Hi there! The fourth answer is correct.

In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.

Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:
$\tan( \alpha ) = \frac{opposite}{adjecent}$

Filling in this formula, brings us to the following answer.
$\tan(45) = \frac{x}{1100}$

Suppose you write a book. The printer charges $4 per book to print it, and you spend $3500 on advertising. You sell the book for

Vesna [10]

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
