Step-by-step explanation:

Mid point of AB is (0, -3)

Coordinate of A is (6, -5)

By using mid point formula, if P(x, y) and Q (x′, y′), then mid point of P= (x + x′)/2 , (y + y′)/2

So, ( 0, -3)= 6+x/2, -5+y/2

0=6+x/2

0=6+x, x = -6

and, -3= -5+y/2, -6= -5+y....

y = -1

so the coordinate is (-6, -1)

To find the midpoint of two points, we can use the following formula:

[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

We're given:

Plug the information into the formula:

[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\\\\(0,-3)=(\dfrac{6+x_2}{2},\dfrac{-5+y_2}{2})[/tex]

If [tex]\dfrac{6+x_2}{2}[/tex] must equal 0, then [tex]x_2[/tex] must be -6.

If [tex]\dfrac{-5+y_2}{2}[/tex] must equal -3, then [tex]-5+y_2[/tex] must equal -6, making [tex]y_2[/tex] equal to -1.

Therefore, BB is (-6,-1).

The telephone pole will stands 10.5 meters tall.

Given shadow of you = 5 meters

The true height is 1.5 meters.

We must determine the telephone pole's height because its lengthy shadow is 35 meters long.

Assume that x is the height of the telephone pole..

Now we can write this as

height of shadow/ actual height

5 / 1.5 = 35 / x

By cross multiplication we get

5 * x = 35 * 1.5

We get it by dividing '5' by both sides

x = 35 * 1.5 / 5

x = 10.5 meters

Therefore ,The telephone pole is 10.5 meters tall.

The Residual is -8.4 hours and the interpretation of the given residual is that the carnation stayed fresh for 8.4 hours less than expected based on how much sugar it received.

A residual plot is a type of scatter plot where the horizontal axis represents the independent variable, or input variable of the data, and the vertical axis represents the residual values.

Now, looking at the given residual plot and using a calculator online, we can say that the equation of the least squares regression line is;

y^ = 180.8 + 15.2x

Now, for 2 tablespoons of sugar , we have x = 2. Thus;

y^ = 180.8 + 15.2(2)

y^ = 212.4 hours

Residual for 204 hours is;

Residual = 204 - 212.4 = -8.4 hours

Thus, the interpretation of the given residual is that the carnation stayed fresh for 8.4 hours less than expected based on how much sugar it received.

Based on the return on assets of 21%, the net income of Pacific Ocean Resort  for year is $166,950

What is return on assets?

The return on assets for the company is determined as the net income divided by the average total assets of Pacific Ocean Resort , bearing in mind that the average total assets is sum of the beginning and ending assets divided by 2

return on assets=net income/average total assets

return on assets=21%

net income=unknown

average total assets=($720,000+$870,000)/2

average total assets=$795,000

The area of the rectangle is equal to b² · (b + 1) · (b + 0.628) · (b + 6.372).

The area of the rectangle is equal to the product of the height and the width, each of them represented by polynomials. In this question we must apply algebraic handling to simplify the product of the two polynomials:

A = h · w           (1)

Where:

If we know that h = b³ + b² and w = b² + 7 · b + 4, then the area of the rectangle is:

A = (b³ + b²) · (b² + 7 · b + 4)

A = b² · (b + 1) · (b + 0.628) · (b + 6.372)

Answer:

0.36933g or 0.3693g in 2.6 x 10^-3 moles of Na2SO4

Step-by-step explanation:

Molar mass

Na = 22.99

S = 32.07

O = 16

Na(2) + S + O(4) =

22.99(2) + 32.07 + 16(4) =

45.98 + 32.07 + 64 = 142.05g

Na2SO4 = 142.05g

2.6 x 10^-3 moles = 0.0026 moles

0.0026 x 142.05 = 0.36933

The simplification of the given equation is (x² + 8x - 16)/(x-4)(x+4) by the method of LCM.

For, the given equation;

4/(x+4) + (x/x-4)

To find the common denominator, use LCM; multiply a first term by (x-4)/(x-4) and the 2nd term by (x+4)/(x+4):

= (x-4)×4/(x-4)(x+4) +  x×(x+4)/(x-4)(x+4)

The following step is to disperse the 4 (x-4) and x (x+4);

So you now have;

= (4x-16 + x² + 4x)/(x-4)(x+4)

Further simplify.

= (x² + 8x - 16)/(x-4)(x+4)

As, (x² + 8x - 16) is further not factor-able. So, the simplified form of the given equation is; (x² + 8x - 16)/(x-4)(x+4).

Step-by-step explanation:

a linear or arithmetic sequence has a start value as first term, and then every following term is created by adding the same constant to the previous term.

a1 = a

a2 = a1 + c = a + c

a3 = a2 + c = a + c + c = a + 2c

a4 = a3 + c = a + c + c + c = a + 3c

...

as we can easily see

an = an-1 + c = a + (n-1)c

in our case

a3 = 17 = a + 2c

a = 17 - 2c

a45 = 269 = a + 44c = 17 - 2c + 44c = 17 + 42c

252 = 42c

c = 6

a = 17 - 2c = 17 - 2×6 = 17 - 12 = 5

so,

an = 5 + (n-1)×6

The least whole number that can be rounded to 230,000 is 225,000.

The ten thousand number (10,000) is usually the fifth digit in a number when counting from the right to the left. For example, in 132,456, 3 is the ten thousand number.

To round off to the nearest ten thousand, if the thousand digit is equal to or greater than 5 (i.e. 5,6, 7, 8, 9), 1 is added to the ten thousand digit and other numbers less than the ten thousand digit becomes 0. For example, when 234,612 is rounded to the nearest ten thousand, the number becomes 235,000.

If the thousand digit is less than 5 (i.e. 0, 1, 2, 3, 4), there is no change in the ten thousand digit other numbers less than the ten thousand digit becomes 0. For example, when 234,412 is rounded to the nearest ten thousand, the number becomes 234,000.

The equation is 50 = (5 + w)w and the width is 5 and the length is 10

The given parameters are

Area = 50

Length = 5 + Width

This means that

l = 5 + w

The area is calculated as

A = lw

Substitute l = 5 + w in A = lw

A = (5 + w)w

Substitute A = 50 in A = (5 + w)w

50 = (5 + w)w

Hence, the equation is 50 = (5 + w)w

We have

50 = (5 + w)w

Express 50 as 10 * 5

So, we have

10 * 5 = (5 + w)w

This means that

5 + w = 10

w = 5

Solve 5 + w = 10

w = 5

Substitute w = 5 in l = 5 + w

l = 5 + 5
