The sum of the angles of an n-sided polygon is (n-2)×180°
For a 30-gon, it would be 28x180 = 5040, answer B
Second question is more of a trick question. Exterior angles always add up to 360. So answer H.
Answer:
Option C. The range is y≥2
Step-by-step explanation:
To solve this, we're gonna demonstrate that all options except option C. are wrong.
Option A. The vertical line confirms that the graph is a function. FALSE.
The vertical line is called the y-axis and it's used as a reference to graph functions. It does not confirm that a graph is a function.
Option B. The domain is x≥2. FALSE.
The domain of a function is the set of possible values of the independent variable "x". In this case, we can deduce from the graph that the variable "x" can take values less than 2.
Option C. The Range is x≥2. TRUE.
The range of a function is the set of all output values of a function. We can deduce from the graph that the variable "y" takes values greater than 2. For that reason, the statement is true.
Option D. This piecewise function is made out of 4 intervals. FALSE.
The function is made out of two intervals. A concave function for x≤2 and a line for x≥2.
Option E. Each interval of the piecewise function contains a graph of a linear function. FALSE.
When x≤2, the graph corresponds to a concave function. So, this interval is not linear.
Hello!
The volume of a cylinder is
r is the radius and h is the height
Square 3.4
3.4 * 3.4 = 11.56
Multiply
11.56 * 11 = 127.16
The answer is
Hope this helps!
Answer =124
4+8+16+32+64=124
I hope this helped! :)
1. 25 - 3x
Then solve for x
