Answer:

this becomes 1/2 * 6 * tan(10) * 3 which results in the area of one of the isosceles triangles is equal to 1.586942826 square units. since there are 18 of these isosceles triangles in the polygon, then multiply this by 18 to get area of the polygon with 18 sides is equal to 28.56497087 square units.

How do I find the domain n range of this graph​
motikmotik

Domain = {-3, 2}

Range = All real numbers

We can represent the range in interval notation as (-\infty, \infty) which is basically saying -\infty < y < \infty. The range is all real numbers due to the arrows meaning the graph extends up and down forever. So any y value is possible.

Notice with the domain we only have 2 valid x values -3 and 2. No other x values are allowed. Normally we use an interval of some kind to set up the domain, but we only have a set of values instead. The curly braces indicate "set".

Describe the graph of y = 3/(4x-12) as compared to the graph of y = 1/x
Ivan
The <span>graph of y = 3/(4x-12) is decreasing sloping to the right mostly in the third quadrant whereas the graph of y = 1/x is like a mirror that is present in both quadrant 1 and 2.</span>

ICE Princess25 [194]

Answer:

2.18

Step-by-step explanation:

The mean is the most familiar average. It is defined as a value obtained by dividing the sum of all observations by their number. It is calculated as

Mean = Sum of all the observations/ Number of the observations

Mean= x₁+x₂+...............+xₐ/n

Where x₁,x₂,...............,xₐ refer to different values of x and n is the sample size.

Mean= 2+1+2+2+2+2+1+3+3+3+3/11= 24/11= 2.18

The mean may correspond to a population or a sample from a population.

The population mean is a fixed quantity where as the sample mean is a variable quantity because different samples from the same population tend to have different means.
