Answer:
see below
Step-by-step explanation:
6 cot ^2 (y) ( sec^2 (y) -1) = 6
We know that ( sec^2 (y) -1) = tan ^2(y)
6 cot ^2 (y) tan ^2 (y) = 6
We know cot = cos/ sin and tan = sin / cos
6 cos/ sin ^2 (y) sin/cos ^2 (y) = 6
6 ( 1) = 6
6=6

Answer:
150
Step-by-step explanation:
First you have to find what number 80 is 2/5 of, to do this do the reciprocal of 2/5 which would be 5/2. Multiply 80 by 5/2 and you'll get 200, then find what 3/4 of 200. Multiply 200 by 3, then divide by 4 to get the answer of 150.

Answer:</h2><h2>
The expected number of people who will attend this concert = 2260</h2>
Step-by-step explanation:
The concert organizers estimate people will attend if it is not raining = 19000
If its raining people will attend = 4000
On the day of the concert, meteorologists predict a 90% chance of rain.
This means 10 % chance of not raining
The expected number of people = 90% (4000) + 10% (19000)
= 360 + 1900
= 2260
The expected number of people who will attend this concert = 2260
