27.) Find the sum of the length of line segments EF and CD

Answers

Answer 1

Answer:

5√10

Step-by-step explanation:

The distance between two points A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) on the coordinate plane is given by:

[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }[/tex]

From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).

Hence the lengths of the line segment EF and CD are:

[tex]|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}[/tex]

Make the following statement an equations (3,-3) m=3

Answers

Answer:

We conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:

[tex]y=3x-12[/tex]

The graph of the line is also attached.

Step-by-step explanation:

Given

The point (3,-3)The slope m = 3

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line (x₁, y₁) is the point

substituting the values m = 3 and the point (x₁, y₁) = (3,-3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-3\right)=3\left(x-3\right)[/tex]

Apply rule: -(-a) = a

[tex]y+3=3\left(x-3\right)[/tex]

subtract 3 from both sides

[tex]y+3-3=3\left(x-3\right)-3[/tex]

simplify

[tex]y=3x-12[/tex]

Therefore, we conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:

[tex]y=3x-12[/tex]

Martha is looking into investing a portion of her recent bonus into the stock market. While researching different companies, she discovers the following standard deviations of one year of daily stock closing prices.
Eye Remember Enterprises:
Standard deviation of stock prices
= $1.25 = $1.25
The Azure Travel Company:
Standard deviation of stock prices
= $9.73 = $9.73
Based on the data and assuming these trends continue, which company would give Martha a stable long-term investment?
A. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has less variability in its closing prices than Eye Remember Enterprises.
B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.
C. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has a greater mean closing price than The Azure Travel Company.
D. The Azure Travel Company; the larger standard deviation indicates that The Azure Travel Company has a greater mean closing price than Eye Remember Enterprises.

Answers

Answer:

Based on the data and assuming these trends continue, the company that would give Martha a stable long-term investment is:

B. Eye Remember Enterprises; the smaller standard deviation indicates that Eye Remember Enterprises has less variability in its closing prices than The Azure Travel Company.

Step-by-step explanation:

The result shows that the greater the standard deviation of the stock price of the Azure Travel Company than that of Eye Remember Enterprises, the greater the variance between each stock's price and their mean closing prices.  This implies a larger price range in the stock of the Azure Travel Company than it is the case with the Eye Remember Enterprises.  It is noteworthy that a volatile stock has a high standard deviation, while the standard deviation of a stable blue chip stock is usually rather low.

Answers

Answer:

-1/2

Step-by-step explanation:

In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.

If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.

The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:

Answers

Answer:

[tex]m = -\frac{2}{5}[/tex] ---- slope

[tex]y = -\frac{1}{3}[/tex] --- y intercept

Step-by-step explanation:

Given

The attached table

Required

Calculate the slope and y intercept

First, we need to calculate the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

From the table, the following relationships exist:

[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]

[tex](x_2,y_2) = (\frac{1}{4},-\frac{13}{30})[/tex]

So, the expression for calculating slope becomes:

[tex]m = [-\frac{13}{30} - (-\frac{1}{30})] / [\frac{1}{4} - (-\frac{3}{4})][/tex]

[tex]m = [-\frac{13}{30} +\frac{1}{30}] / [\frac{1}{4} +\frac{3}{4}][/tex]

Take LCM

[tex]m = [\frac{-13+1}{30}] / [\frac{1+3}{4}][/tex]

[tex]m = [\frac{-12}{30}] / [\frac{4}{4}][/tex]

[tex]m = [\frac{-12}{30}] / 1[/tex]

[tex]m = \frac{-12}{30}[/tex]

[tex]m = \frac{-2}{5}[/tex]

[tex]m = -\frac{2}{5}[/tex]

To calculate the y intercept:

x must be 0. i.e.

[tex]x = 0[/tex]

So, we have:

[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]

[tex](x_2,y_2) = (0,y)[/tex]

[tex]m = -\frac{2}{5}[/tex]

Substitute these values in:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]-\frac{2}{5} = [y - (-\frac{1}{30})] / [0- (-\frac{3}{4})][/tex]

[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [0+\frac{3}{4}][/tex]

[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [\frac{3}{4}][/tex]

Multiply through  by 3/4

[tex]-\frac{2}{5}*\frac{3}{4} = y +\frac{1}{30}[/tex]

[tex]-\frac{6}{20} = y +\frac{1}{30}[/tex]

[tex]-\frac{3}{10} = y +\frac{1}{30}[/tex]

Collect Like Terms

[tex]y = -\frac{3}{10}-\frac{1}{30}[/tex]

[tex]y = \frac{-9-1}{30}[/tex]

[tex]y = \frac{-10}{30}[/tex]

[tex]y = \frac{-1}{3}[/tex]

[tex]y = -\frac{1}{3}[/tex]

A lemonade seller calculates that it costs $ to produce glass of lemonade and $ to produce glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing glass of lemonade

Answers

Question:

A lemonade seller calculates that it costs $50 to produce 52 glass of lemonade and $110 to produce 127 glass of lemonade. Assume the relationship between the cost and the number of glass of lemonade produced is linear. What is the most reasonable estimate for producing 193 glass of lemonade?

Answer:

[tex](a).\ y = 0.8x + 8.4[/tex]

[tex](b).\ Estimate = \$163[/tex]

Step-by-step explanation:

Represent number of lemonade with x and the cost with y.

So:

[tex](x_1,y_1) = (52,50)[/tex]

[tex](x_2,y_2) = (127,110)[/tex]

Solving (a): The linear relationship between them.

First, calculate slope (m)

m = ∆y ÷ ∆x

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{110 - 50}{127 - 52}[/tex]

[tex]m = \frac{60}{75}[/tex]

[tex]m = 0.8[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 50 = 0.8(x - 52)[/tex]

[tex]y - 50 = 0.8x - 41.6[/tex]

Make y the subject

[tex]y = 0.8x - 41.6 + 50[/tex]

[tex]y = 0.8x + 8.4[/tex]

Solving (b): Estimate of 193 lemonade

In (a), we have:

[tex]y = 0.8x + 8.4[/tex]

Substitute 193 for x

[tex]y = 0.8 * 193 + 8.4[/tex]

[tex]y = 154.4 + 8.4[/tex]

[tex]y = 162.8[/tex]

[tex]Estimate = \$163[/tex]

You have three throws a turn.
What different totals can you
make on each turn?
30
90

Answers

Answer:

10 different total we can make.

Step-by-step explanation:

Consider the provided information.

It is given that we have three hoops and three cones of numbers 30, 40 and 90.

We are assuming that if we throw a hoop, it always falls on a cone.

Then the different totals are shown below:

If all three hoops fall on the same cone.

1) 30+30+30=90

2) 40+40+40=120

3) 90+90+90=270

If two out of three hoops fall on the same cone.

4) 30+40+40=110

5) 30+90+90=210

6) 40+30+30=100

7) 40+90+90=220

8) 90+30+30=150

9) 90+40+40=170

If all the hoops fall on the different cone.

10) 30+40+90=160

Hence, 10 different total we can make.

Error Analysis A contractor purchases 5 dozen pairs of padded work gloves for $69.60. He
incorrectly calculates the unit price as $13.92 per pair for the expense report What is the correct unit
price? What is the error?
The correct unit price is $ per pair

Answers

Answer:

The correct unit price is $1.16 per pair.

The contractor calculated the unit price in terms of per dozen.

Step-by-step explanation:

Given that:

Cost of 5 dozen pairs = $69.60

Unit price per dozen = [tex]\frac{69.60}{5} =\$13.92[/tex]

Unit price means the price of one pair of padded work gloves, so we will convert dozens into unit.

1 dozen = 12 pairs

5 dozen = 60 pairs

Unit price = [tex]\frac{69.60}{60}[/tex]

Unit price = $1.16 per pair

Hence,

The correct unit price is $1.16 per pair.

The contractor calculated the unit price in terms of per dozen.

Answers

Answer:

Slope of XZ = -5/9

Slope of YZ  = 2/7

Slope of XY  = -7/2

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

For XZ

X(−5, 5), and Z(4, 0)

Slope of XZ = 0-5/4-(-5)

Slope of XZ = -5/4+5

Slope of XZ = -5/9

For YZ

Y(−3, −2), and Z(4, 0).

Slope of YZ = 0-(-2)/4-(-3)

Slope of YZ = 2/4+3

Slope of YZ  = 2/7

For XY

X(−5, 5), Y(−3, −2)

Slope of XY = -2-5/-3-(-5)

Slope of XY = -7/-3+5

Slope of XY = -7/2

For two lines to be perpendicular, the product of their slope must be -1

Taking the product of XY and YZ

mXY * mYZ = -7/2 * 2/7

mXY * mYZ  = -1

since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle
