What basic trigonometric identity would you use to verify that csc x sec x cot x= csc^2x.
Answers
Answer:
See below.
Step-by-step explanation:
I would use cot x = cos x / sin x:
csc x sec x cot x
= csc x * 1/cos x * cos x / sin x
The cos x disappears:
= csc x * 1 / sin x
= csc^2 x.

Answer:
23/99
Step-by-step explanation:
0.23 is x.
Because x is recurring in two decimal places, we will multiply it by 100.
100x=23.23
Then we subtract.
100x-x=23.23-0.23
99x=23
x=23/99

Answer for Blank 1:
Question 2 Maya and Sally were the two finalists in a singing competition. The person with the most votes from the audience was chosen as the winner. Sally received 25% of the total votes and lost by 62,500 votes. No person in the audience was allowed to vote more than once. The equation below represents this situation, where y is the total number of votes cast and x is the number of votes Maya received.
x - 62,500 = 0.25y
If a total of 125,000 people voted, how many votes did Maya receive?

x - Tim`s age, y - Coach Johnson`s age:
x + 10 = y
2 * ( x - 3 ) = y - 3
-----------------------
2 x - 6 = x + 10 - 3
2 x - x = 7 + 6
x = 13
Tim is 13 years old.
Question 2:
x - 62,500 = 0.25 * 125,000
x - 62,500 = 31,250
x = 31,250 + 62,500
x = 93,750
Maya received 93,750 votes.
