Answer:
It's A
Step-by-step explanation:
Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.
The answer is 88.8% how i got it is by:
30-18= 12 which is the number of member that had an average of 84
then multiply 12 times 84 = 1008 (keep this number)
last you multiply 18 by 92 which equals 1656
add 1008 and 1656 together and get 2664.
divide 2664 / 30 and you get the average of 88.8
Step-by-step explanation:
|y – 3| − 4 ≤ −3
|y – 3| ≤ -3+4
|y – 3| ≤ 1
-1 ≤ y-3 ≤ 1
=> -1 ≤ y - 3 or y - 3 ≤ 1 (the first option)
