Answer:
$10
Step-by-step explanation:
Each hardcover book costs $12, resulting in a total of $60 for five of them out of $100. The remaining four paperbacks at $10 each amount to a total of $40.

The sequence ABC is oriented clockwise in both diagrams, indicating an even number of reflections or a rotation.
A 90° clockwise rotation about the point (-3, -3) would accomplish the necessary transformation, but that is not a listed option. An equivalent action is...
• reflect across the line x = -3
• reflect across the line y = x
The question seems to require answer choices, which are provided below:
a) sqrt(1 - x^2)
<span>b) x / sqrt(1 - x^2)</span>
<span>c) sqrt(1 - x^2) / x</span>
<span>d) 1 / sqrt(1 - x^2)
</span>
The correct selection is <span>c) sqrt(1 - x^2) / x</span>.
This is because cos u equals sqrt(1 - sin² u), which is sqrt(1 - x²), and cot u is defined as cos u divided by sin u.
