The answer is 90 because 360/4 (since it is a quadrilateral) is 90 degrees
Yes it does mean that. As long as a number is next to a number with parenthesis with no sign in between, consider it as multiplication.
A^2 + b^2 = c^2
8^2 + b^2 = 11^2
64 + b^2 = 121
b^2 = 121 - 64
b^2 = 57
b = sqrt 57
b = 7.54 rounds to 7.5 ft <==
Yes I think your correct I don’t really understand the question ..
Answer:
(-2, 4) U [7, ∞)
Step-by-step explanation:
The domain of a function is the set of inputs at which the functions is defined. Usually determined by the x-values. In this problem we have the graph of a function. At x = -2 the function is not defined, we can see this by taking a look at the opened circle at this value in the graph. Then the function takes values until x = 4. Notice that at x = 0 the function is defined. At x = 0 to left the function takes the value y = 0 and at x = 0 to the right the function takes the value y = -1. Then the function takes value at x = 7 (including this value because of the closed circle in the graph) and beyond. Therefore, the correct answer is:
(-2, 4) U [7, ∞)
