Answer:
2,4,6,7,8,17
Step-by-step explanation:
Cosecant (csc) is defined as the reciprocal of sine, therefore:

.
1/sinx will be undefined when the denominator sinx = 0.
Recalling the unit circle, sinx = 0 at x = 0 ± πn, where n is an integer.
Since the domain x is restricted from (0, 2π), we only consider the values x = 0, x = π, and x = 2π.
Therefore in the domain 0 ≤ x ≤ 2π, y = csc(x) will be undefined at x = 0, x = π, and x = 2π.
Answer:
The perimeter is 100 ft
Step-by-step explanation:
Width = 9 ft
It is five times as long as it is wide
Length = 5*width = 5*9 = 45 ft
P = 2(l+w)
=2(45+5)
=2(50)
= 100 ft
