Stephanie earned 8 points for every book she read over the summer. The equation y = 8x represents Stephanie's points based on th
e number of books she read.
Use the table and equation to complete the statements and find the number of books Stephanie read.
1. Stephanie earned 72 points. Did she read fewer than 2 books, between 2 and 5 books, between 5 and 6 books, or more than 7 books? Explain how you know.
2. The equation y = 8x gives the points, y, earned by reading x books.
Use this equation to find the number of books Stephanie read to earn 72 points. Show your work.

Step-by-step explanation:
Using the trigonometric identities
tan(90 - x) = cotx , cotx =
Given
tan1tan2tan3....................... tan87tan88tan89
= tan1tan2tan3............... tan(90-3)tan(90-2)(tan90 - 1)
= tan1tan2tan3.............. cot3cot2cot1
= tan1cot1tan2cot2tan3cot3 ........................
= 1 × 1 × 1 ×....................... × 1
= 1
