QUESTION 1: In Exercises 5–8, use the method illustrated in Example 2 to determine moving averages by subtraction and addition. Determine the 6-day SMA for the ten consecutive trading day closing prices for SunEdison Inc. Listed below. $2.65, $2.63, $2.70, $2.63, $2.50, $2.65, $2.66, $2.56, $2.52, $2.37 * 5 points

Answers

Answer:

The 6-day SMA for the ten consecutive trading day

= $2.63,  $2.63,  $2.62,  $2.59,  $2.54

Step-by-step explanation:

Determining the 6-day SMA for the given values

using the addition and subtraction methodology

First we will determine the Average closing prices for 1 - 6 days

=  [tex]\frac{2.65 + 2.63 + 2.70 + 2.63 + 2.5 + 2.65}{6}[/tex]  =  15.76 / 6 =  $2.626 ≈ $2.63

next we have to determine the SMA for days 2 - 7

= 2.63 - [tex]\frac{2.65}{6} + \frac{2.66}{6}[/tex]  =  [tex]\frac{15.77}{6}[/tex]  ≈ $2.63

SMA for days 3 - 8

= 2.63 -  [tex]\frac{2.63}{6} +\frac{2.56}{6} = \frac{15.70}{6}[/tex] ≈  $2.62

SMA for days 4 - 9

= 2.62 - [tex]\frac{2.70}{6} + \frac{2.52}{6} = \frac{15.52}{6}[/tex]  ≈  $2.59

SMA for days 5 - 10

= 2.59 - [tex]\frac{2.63}{6} + \frac{2.37}{6} = \frac{15.26}{6}[/tex]  ≈  $2.54

Hence the 6-day SMA for the ten consecutive trading day

= $2.63, $2.63, $2.62, $2.59, $2.54

To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.

is the function y= sin(x)/x even, odd or neither

Answers

the function is odd

The function y = sin(x) / x is an even function.

What is an even function?

Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.

The equation should be stored in an even function:

f(-x) = f(x)

The function is given as,

y = sin(x) / x

Put x = -x, then we have

y = sin(-x) / (-x)

y = -sin(x) / (-x)

y = sin(x) / x

The function y = sin(x) / x is an even function.

WHY must the same operation be performed on both sides of an equation? ​

Answers

Answer:When you are given a problem, the two sides are equal, so they are equally weighted. As long as you do the same thing on both sides, they remain the same weight. The only way that one side can become "more weight" on a side is if you make a math mistake, and thus the answer would not satisfy the original equation

I need help finding the slope, The y-intercept, and the equation??

Answers

Answer:

y intercept is (0, 1)

slope is 3

equation is y = 3x +1

Step-by-step explanation:

You find the y intercept when x equals 0 and you can see that on the table that is 1.

You find slope by y2-y1 divided by x2-x1. if you pick (0,1) and (1,4) it is 4-1/1-0 which equals 3.

Therefore the equation is y = 3x + 1 in slope intercept form because the slope is 3 and y int is 1.

29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 4

13y - 17 = 29x - 3 because these two angles are alternate
