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.

Answer:

All of those which summed are more that the third side, so the second is the only possible answer.

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.

Answer:

  either

Step-by-step explanation:

They could represent either:

  2^2 = 4 . . . a rational number

  2^(1/2) = √2 . . . an irrational number

The fact that a number has an exponent does not make it either rational or irrational.

Additional comment

You can also consider irrational numbers with exponents.

  (∛2)^2 = 2^(2/3) . . . irrational

  (√2)^2 = 2^1 . . . . . . rational

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

x = 20*sin(15) = 5.176 units

Answer:

B. No solution

Step-by-step explanation:

Given that the result of the equation is 3 = 5

Therefore the results of the equation is impossible to be correct, and therefore, there are no values that can be given to the variables to make the equation true.

The characteristics of an equation with no solution is one whose result makes a statement that is false, such as given in the question, and the equations are said to be contradictory or not compatible.

The function y = sin(x) / x 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.
