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
Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where, and , is called the argument of z, .
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5. lies in 4th quadrant.
So, the trigonometric form is
