<u>Answer</u>
sinx = -1
<u>Explanation</u>
The graph below shown is a sine wave (sine graph).
This is because; sin0 = 0, sin90 = 1, sin 180 = 0, sin270= -1, and sin360= 0. This can be confirmed in the graph shown.
The line shown is the line, y = -1.
The two intersect at sinx = -1
Answer: The last paper has to be 99 over 100 to move the class average by 1 point
Step-by-step explanation:
total points on the 23 exams: 23*75 = 1725
-----
For 24 papers to average 76 points you need 24*76= 1824
---
Score on the final paper would have to be (1824-1725) = 99
Substitute -1 for the variable x.
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
Variables are like a substitute for a number
