Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
3 * 1 * -1 because 3 times one is 3 and that times a negative turns it into a negative. ( positive * negative = negative)
Answer:
64
Step-by-step explanation:
Perfect squares are integers multiplied by themselves.
- 2 times 2 = 4
- 3 times 3 = 9
- 4 times 4 = 15
The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).
49 is less than 54, so that's ruled out.
Therefore, the closest perfect square to 54 that is greater than it is 64.

$50S = $1,850 - $350 = $1,500
S = 1,500/50 = 30
Therefore, 30 skiers went on the trip
