Answer:
A) If the domain of y=cos(x) is restricted to [0, π], y=cos^-1(x) is a function.
Step-by-step explanation:
In order for the inverse function to be a function, the original must pass the horizontal line test: a horizontal line must intersect the function in only one place.
As you can see from the attached graph, restricting the cosine function to the domain [0, π] allows it to pass the horizontal line test, so its inverse will be a function.
__
Restricting the domain to [-π/2, π/2] does not limit cos(x) to something that will pass the horizontal line test.
Lateral area is the area of the sides only.
Each side is a rectangle.
A = 4*8 + 6*8 + (sqrt52) * 8
A = 32 + 48 + 57.7
A = 137.7 ft^2
OR
A = 32 + 48 + 57.69
A = 137.69 ft^2
Depends on required rounding.

Answer:
Step-by-step explanation:
x is the supplement of 133
x + 133 = 180
x + 133 - 133 = 180 - 133
x = 47
