The value of the scale factor k, is 1.5
<h3>
Perimeter</h3>
The perimeter of a shape is the sum of the side lengths of the shape
<h3>
Dimensions </h3>
The dimensions of the triangle MNO are given as:



Calculate the perimeter of the triangle as follows:


Divide 17.25 by 11.5 to calculate the scale factor (k)


Hence, the scale factor is 1.5

The area is the sum of 'n' rectangle areas.
The width of the rectangle is size of interval, (domain size)/n
The height of each rectangle is f(interval) as interval moves along domain.
For this example, domain size = 3-1 = 2
size of interval = 2/n
height varies from f(1) to f(3), increasing by 2/n each time.
f(1+(2/n)i)
Putting this together, the area is the sum of:

Since you are given the function f(x). Sub input into f(x) to get area in terms of n and i.

Finally, the summation is:
The answer is A. Just took the test and got it right.
Because a +3 is located inside the absolute value bars, you shift the function's graph to the left 3.
There is a -1 being multiplied by the absolute value, so every answer must be negative.
Therefore, the graph should be shifted to the left 3 and open down, or answer choice C.
