The coordinate points on the line plotted satisfy the equation -

y + 1/3x = 4.

We have the equation of a straight line.

We have to find the coordinates that satisfy this equation.

The general equation of straight line is -

y = mx + c

According to the question -

y + 1/3x=4

y = - (1/3)x + 4

Comparing it with general equation of line, we get -

m = - 1/3  and  c = 4

Now, we will plot the line on graph -

All the coordinate points that are present on this line satisfy the equation of line. The graph extends in both the direction along the x - axis.

Hence, the coordinate points on the line plotted satisfy the equation

The standard deviation is 6.09

The variance is 37.04.

Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.

In order to determine the standard deviation, take the following steps:

(162 - 170.40)² + (166-  170.40)² + (179 -  170.40)² + (170 -  170.40)² + (175 -  170.40)²

70.56 + 19.36 + 73.96 + 0.16 + 21.16 = 185.20

√185.20 / 5 = 6.09

Variance measures the rate of dispersion of a data point around the dataset. It can be calculated by finding the square of the standard deviation of a dataset.

The wavelength  λ , of a photon that has an energy of E = 4.26×10^−19 J is 21504.29 meter.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now, the given equation for photon energy, E , is

E = hcλ

Here, h = 6.626×10^−34 J⋅s (Planck's constant) and

c = 2.99×10^8 m/s (the speed of light)

Therefore, we have

E = hcλ

⇒ λ = E/hc

Put the values of E, h and c we get,

λ = 4.26×10^−19 / (6.626×10^−34*2.99×10^8)

Solving we get,

λ = 4.26×10^−19 / 19.81×10^(−34+8)

⇒ λ = 4.26×10^−19 / 19.81×10^-26

⇒ λ = (4.26/19.81)*10^(-19+26)

⇒ λ = 0.215042×10^5 meter

⇒ λ = 21504.29 meter

Thus, the wavelength  λ , of a photon that has an energy of E = 4.26×10^−19 J is 21504.29 meter.

Answer:

x = -4

Step-by-step explanation:

A perpendicular bisector is a line that divides the existing line or shape evenly and at 90° angles. First, we want to find the center point of our existing line. In this case, the center sits right at x = -4. Since the existing line is y = 3 and it is perfectly horizontal, we don’t need to do anything further. Our perpendicular bisector is x = -4.

*** When the existing line is y = [singular number], the perpendicular bisector will always be x = [midpoint of existing line], and vice versa.

The parent function, f(x) = |x|, and the graph of the parent and translated function, gives the equation of the translated graph as; f(x) = |x + 3|

The given parent function is; f(x) = |x|

From the parent function, we have;

When x = 0, f(0) = 0

The graph of the parent function is therefore the red graph.

The location of the vertex of the translated graph is at (x - 2, y + 1)

Given that the slope of the image of the graph of the parent function is the same as the slope of the graph of the parent function, we have;

(x, y) → (x - 2, y + 1)

Therefore in the image, the coordinates of y = x + 3

Which gives the equation for the translated graph as; y = |x + 3|

The slope of the tangent is equal to zero when the derivative is equal to zero, in other words when the function attains a local extremum (maximum or minimum)

So we have to ask ourselves, at which "x" value does f(x) admit a maximum or minimum.

From the graph we can tell that it is at the point of abscissa 2

The value of the 401(k) after 18 years is $173,526 , the value of the 401(k) at the age of 65 is $1,273,424 and the difference between the amount of money you will have accumulated in the 401(k) and the amount you contributed to the plan is $1,192,724

As per the given information, you contribute $3000 p.a. and your employer contributes $1500 p.a. to a 401(k)

So, the total amount contributed for 401(k) = $3000+$1500 = $4500 p.a.

This is a case of annuity because fixed amount is contributed each year.

Future value of an annuity is given by a formula = a [tex]\frac{(1+i)^{n} -1}{i}[/tex]    

Where, a = annuity = $4500

i = rate of interest = 8.3% p.a. or 0.083

n = no. of years or periods = 18

Now, substituting the values in the formula,

FV of Annuity =  4500 [tex]\frac{( 1+ 0.083)^{18}-1 }{0.083}[/tex]

 = 4500 [tex]\frac{4.2006 - 1}{0.083}[/tex]

= 4500 × 38.5614

= 173526.3

The future value of 401(K) after 18 years is $173,526

Now, After 40 years no contributions are made to the funds. Therefore, the future value at age 65 (after 25 years):

By applying compound interest formula, the future value = p × [tex](1+i)^{n}[/tex]

Here, p = present value or principal amount = $184,036

i = rate of interest = 8.9% or 0.089

n = no. of years or periods = 25

Substituting  the values:

Future value = $173526 × [tex](1+0.083)^{25}[/tex]

= 173526 × 7.34025

 = 1273724.22

You will have $1,273,424 in the plan at age 65.

Now, The difference between the amount of money you will have accumulated ate the age of 65 and the amount you

contributed (for 18years) in the plan = $1,550,956 – ($4500×18)      

= $1273724 - $81000

= $1,192,724

Hence, the value of the 401(k) after 18 years is $173,526 , the value of the 401(k) at the age of 65 is $1,273,424 and the difference between the amount of money you will have accumulated in the 401(k) and the amount you contributed to the plan is $1,192,724

We need to find the slope of the line that contains these two points.

We know that the formula for calculating the slope of the line is given by:

Here, we have:

x₁ = - 1                     y₁ = 8

x₂ =  8                     y₂ = 9

Substituting the values in the formula, we get that:
