Vector V Is Shown In The Graph.Which Are The Magnitude And Direction Of V? Round The Answers To The Thousandths

Answers

Answer 1

Step 1:

First, draw and label the vertical and the horizontal units of the vector.

Step 2:

Write the column vector

[tex]v\text{ = }\begin{bmatrix}{4} & \\ {8} & {}\end{bmatrix}[/tex]

Step 3:

[tex]\begin{gathered} \text{Magnitude of v = }\sqrt[]{v^2_x+v^2_y} \\ v_x\text{ = 8 } \\ v_y\text{ = }4 \\ \text{Magnitude of v = }\sqrt[]{8^2+4^2} \\ =\text{ }\sqrt[]{64\text{ + 16}} \\ =\text{ }\sqrt[]{80} \\ MagnitudeofV=\text{ 8.944} \end{gathered}[/tex]

Step 4:

Find the direction using the formula below

[tex]\begin{gathered} tan\theta\text{ = }\frac{v_y}{v_x} \\ \tan \theta\text{ = }\frac{4}{8} \\ \tan \theta\text{ = 0.5} \\ \theta=tan^{-1}(0.5) \\ \theta\text{ = }26.565 \end{gathered}[/tex]

Final answer

[tex]\begin{gathered} \text{Magnitude = 8.944} \\ \text{Direction = 26.565} \\ \mleft\Vert v\mleft\Vert\text{ = 8.944 , }\theta\text{ = 26.565}\mright?\mright? \end{gathered}[/tex]

Answers

Using the given scatter plot, let's describe the relationship between the average income in a city and the average rent for a 1-bedroom apartment in that city.

Here, the average income is represented on the x-axis while the average rent is represented on the y-axis.

Using the scatter plot, we can see that as the average income increases, the average rent also increases.

Since one variable increase as the other increases, and the points show a straight line pattern, we can say the relationship between them is a positive linear association.

Therefore, the relationship between the average income and the average rent for a 1-bedroom apartment in that city is a positive linear association.

ANSWER:

A. Positive linear association.

Given the mean score of a group of people in a quiz, the standard deviation of the scores of the people, and the score of a person, we can easily determine the z-score like this:

[tex]z=\frac{x-μ}{σ}[/tex]

Where σ is the standard deviation, μ is the mean score and x is the score. By replacing 78 for μ, 4.2 for σ and 80 for x, we get:

[tex]z=\frac{80-78}{4.2}=0.4762[/tex]

Then the z-score equals 0.4762. In this case, the score of 80 is a usual value since it is within one standard deviation of the mean.

point a is to the left of point B on the horizontal number line what could be the valves of point a and point B

Answers

Answer:

If point A is to the left of point B, point A is less than B. Therefore, the values of point A and B could be:

A = 7 and B = 9

A = -8 and B = -5

A = -10 and B = 2

Because 7 is less than 9, -8 is less than -5, and -10 is less than 2.

The value of (3.22 - 2.96)×10³ is  0.26×10³.

What is scientific notation?

We use scientific notation for writing large numbers in compact form.

Scientific notation is written in base multiplied by 10 raised to some power where 0 ≤base < 10 scientific notation also has an alternative name which is known as engineering notation.

We know when we have numbers in scientific notation with the same exponent value we can do arithmetic operations to the base.

∴ (3.22x10³) - (2.96x10³).

= (3.22 - 2.96)×10³.

A certain group of women has a 0.97​% rate of​ red/green color blindness. If a woman is randomly​ selected, what is the probability that she does not have​ red/green color​ blindness?

Answers

The probability that a randomly selected women does not have red/ green color blindness is 0.9903.

The probability of a woman has red/ green color blindness is,

P (Color blindness) = 0.0097.

The probability that a randomly selected women does not have red/ green color blindness is,

P (No Color blindness) = 1 - P (Color blindness)

                                    = 1 - 0.0097

                                    = 0.9903

Thus, the probability that a randomly selected women does not have red/ green color blindness is 0.9903.

Hence the probability that the women does not have red/green color blindness is 0.9903.

Find what X equals [tex]2(x + 7) = - 4x + 14[/tex]

Answers

To solve the expression: 2(x + 7) = - 4x + 14, just follow these steps:

1. Distribute the product on the left side of the equation:

2(x + 7) = - 4x + 14

2*x + 2*7 = - 4x + 14

2x + 14 = -4x + 14

2. subtract 14 on both sides:

2x + 14 - 14 = -4x + 14 - 14

2x = - 4x

3. Add 4x on both sides:

2x + 4x = -4x + 4x

6x = 0

4. Divide both sides by 6:

6x/6 = 0

x*6/6 = 0

x*1 = 0

x=0

Then x equals 0

if a (9,18) and b = (1,12) what is the length of ab

To calculate the lenght of AB we'll use the formula for distance between two points.

Remember that the disnatce between points

is:

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

Using this, and the data given,

Zena's Z-score on the chemistry final was 0.65. If the class mean on the final was 78, the the standard deviation was 12, and the distribution was normal, what was Zena's raw score?

Answers

Zena's raw score in the chemistry test is 85.8

How to determine the raw score of the test?

From the question, the given parameters are

Mean score of the class = 78Standard deviation of the class = 12z-score of the test = 0.65

The z-score of the distribution is calculated using the following z-score  formula

z = (raw score - mean value)/standard deviation

Substitute the given parameters in the above equation

So, we have the following equation

0.65 = (Raw score - 78)/12

Cross multiply in the above equation

Raw score - 78 = 7.8

Add 78 to both sides

Raw score = 78 + 7.8

Evaluate

Raw score = 85.8

Hence, the raw score is 85.8

A line includes the point (7,5)has a slope of 1.What is its equation in slope intercept form?

Answers

Given:

Point( 7, 5)

x = 7 and y=5

slope(m) = 1

We need to first find the intercept.

Substitute x=7, y=5 and m=1 into y=mx + b and solve for intercept(b)

5 = 1(7) + b

5 = 7 + b

5 - 7 = b

-2 = b

Now, form the equation by substituting the value of the slope and intercept into y=mx + b

y = x - 2

Find the area of the shaded region.6005 cmA = [?] cm2Enter a decimal rounded to the nearest tenth.

Answers

To determine the area of the shaded region we first need to calculate the area of the whole circle, then we need to calculate the area of the circular sector of 60º, then finally we will calculate the area of the triangle and subtract the area of the triangle from the area of the circular sector, this will be the area of the part that isn't painted. Finally we can subtract the area that isn't painted by the area of the circle to determine the shaded region.

To calculate the area of the circle we will do as follows:

[tex]A_{\text{circle}}=\pi\cdot r^2=\pi\cdot5^2=25\cdot\pi=78.5[/tex]

The circular sector can be calculated by the following expression:

[tex]A_{\text{sector}}=\frac{60\cdot\pi\cdot r^2}{360}=\frac{\pi\cdot5^2}{6}=\frac{25\cdot\pi}{6}=13.08[/tex]

All of the sides of the triangle are equal, so we can use the following expression:

[tex]A_{\text{triangle}}=\frac{l^2\sqrt[]{3}}{4}=\frac{5\cdot\sqrt[]{3}}{4}=2.163[/tex]

Now we will subtract the area of the triangle from the area of the sector to determine the area that isn't shaded.

[tex]A_{\text{blank}}=13.1-2.163=10.937[/tex]

To finish we will subtract the area that isn't shaded from the area of the circle.

[tex]A_{\text{shaded}}=78.54-10.937=67.6[/tex]

The area of the shaded region is 67.6 cm²

The slope of the line is. (Type an integer or a simplified
fraction.)
B. The slope of the line is undefined.

Answers

Option A. The slope of the line is zero

How is the slope calculated?

First point = [tex](x_1,y_1)=(-3, -1)[/tex]

Second point = [tex](x_2,y_2)= (3,-1)[/tex]

Slope of the line = m

                       [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\m =\frac{-1+1}{3+3} \\\\m = \frac{0}{3} \\\\m= 0[/tex]

Thus the slope of the line is zero.

What is a zero slope?

The slope will be 0 if time passes without any change and is called a zero slope. Here each y point in a horizontal line is identical. This implies that the slope will always be zero because the numerator of the fraction will always equal zero.A vertical line is an undefined slope where the x-points  never change as the y-points rise and fall. The zero slope equation, or y = b, is the formula for a line with no slope, also known as a horizontal line.
