<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>

Answer:
273 Touchdowns
Step-by-step explanation:
You divide the amount of confetti cannons set off by the amount of confetti cannons set off every time there is a touchdown scored. So in this case 181818 ÷ 666
Answer:
Percentage rise in patients from 2004 to 2014 = 7.59%
Explanation:
The number of patients in 2004 = 39080
The number of patients in 2014 = 42045
Increase in the number of patients = (The number of patients in 2014) - (The number of patients in 2004)
Rise in the number of patients = 42045 - 39080
Rise in the number of patients = 2965
Percentage rise in patients from 2004 to 2014 = 7.59%
Answer:
x = 19
Step-by-step explanation:
YZ || XW, so ∠Y = ∠W
if ∠Y = ∠W, then ∠W = 2x
since the sum of the angles of a triangle is 180 degrees:
(3x-5) + 2x + 90 = 180
x = 19
