Answer:

Step-by-step explanation:
Cosecant function is undefined when angle is 0 radians and equal to 1 when angle is 0.5π. The graphic shows a translation of 2 units in the +y direction. Then, the function is:

Answer:
L=10cm , W=30cm
Step-by-step explanation:
First use the given that W=10+2*L
Use P=2W+2L=80, substitute W in the perimeter formula
2(10+2L)+2L=80 and solve for L,
20+4L+2L=80 isolate variable L and combine like terms,
6L=80-20,
L=10, so W=10+2*10=10+20=30
Factor out common factors.
-x³-4x²-5x = -x(x² + 4x + 5)
-x(x² + 4x + 5) is your answer
