5. (3 marks) Determine the area of the parallelogram formed by the following vectors:
u = (1,2,2) , v = (4.4.0)

Answers

Answer 1

The area of the parallelogram formed by the vectors u and v is 12.

The area of a parallelogram formed by two vectors u and v can be determined by finding the cross product of the two vectors and then taking the magnitude of the resulting vector.

First, we need to find the cross product of u and v:

u × v = [(2)(0) - (2)(4), (2)(4) - (1)(0), (1)(4) - (2)(4)] = [-8, 8, -4]

Next, we need to find the magnitude of the resulting vector:

|u × v| = √((-8)² + (8)² + (-4)²) = √(64 + 64 + 16) = √144 = 12

Therefore, the area of the parallelogram formed by the vectors u and v is 12.

graphing linear equations in 2 variables

Answers

By solving the given equation, we can plot these two points on a coordinate plane, and then connect the points with a line. The formed line is the graph of the linear equation 3y=2x-7.

What is a coordinate plane?

The coordinate plane is made up of two perpendicular lines called the x-axis and the y-axis. The x-axis, which is horizontal, is used to measure the distance of a point from the left and right side of the plane. The y-axis, which is vertical, is used to measure the distance of a point from the top and bottom of the plane.

To graph the equation 3y=2x-7, we first need to identify two points that satisfy the equation. We can do this by plugging in different values for x and solving for y. For example, when x=0, the equation becomes 3y=-7. Thus, one point that satisfies the equation is (0,-7). We can find a second point by plugging in a different value for x. For example, when x=2, the equation becomes 3y=-3. Thus, the second point that satisfies the equation is (2,-3).

Now, we can plot these two points on a coordinate plane, and then connect the points with a line. The formed line is the graph of the linear equation 3y=2x-7.

There are 5 yellow, 4 green and 3 black balls in a bag. All the 12 balls are drawn one by one and arranged in
a row. Find out the number of different arrangements possible.​

Answers

There are 27720 different arrangements possible.

The number of different arrangements possible can be found using the formula for permutations with repetition:

n! / ([tex]p{1}[/tex]! * [tex]p{2}[/tex]! * ... *[tex]p_{k}[/tex]!)

where n is the total number of items, and [tex]p{1}[/tex], p2, ..., pk are the number of times each item is repeated.

In this case, n = 12 (the total number of balls), [tex]p{1}[/tex] = 5 (the number of yellow balls), [tex]p{2}[/tex] = 4 (the number of green balls), and [tex]p{3}[/tex] = 3 (the number of black balls).

So the number of different arrangements possible is:

12! / (5! * 4! * 3!)

= 479001600 / (120 * 24 * 6)

= 27720

Therefore, number of different arrangements possibleis 27720.

A summer camp is organizing a hike and needs to buy granola bars for the campers. The granola bars come in small boxes and large boxes. Each small box has 10 granola bars and each large box has 30 granola bars. The camp bought a total of 6 boxes that have 100 granola bars altogether. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.

Answers

There will be 4 small boxes and 2 large boxes of granola bars.

What are variables?

A variable is an attribute or a phenomenon that can be measured and has a changing value over time.

Given,

Number of granola bars in the small box = 10

Number of granola bars in the large box = 30

The number of small boxes = three times the number of a large boxes

To Find,

The number of small boxes purchased =?

The number of large boxed purchased =?

Let the number of large boxes be y

The number of small boxes be x

Total number of boxes, x + y = 6         ..... equation i

Total number of granola bars in small box = 10x

Total number of granola bars in large box = 30x

So, 10x + 30x = 100

After dividing by 10 we get

x + 3y = 10                                               ..... equation ii

Subtracting equation ii from equation i

We get,   2y = 4

y = 2

Putting the value of y in equation i we get x = 4

So, there will be 4 small boxes and 2 large boxes of granola bars.

Train wheels are designed to slope inward toward the track to keep the train stable as it goes around curves. However, as the slope of the wheels increases, it becomes less efficient at producing speed. How might making changes in the slope of a train's wheels affect the train overall?

Answers

There is a trade-off between stability and speed when it comes to the slope of a train's wheels.

What is slope ?

Slope is a measure of the steepness of a line or a surface. In mathematics, slope is often represented by the letter "m" and is calculated as the change in the vertical direction (y-axis) divided by the change in the horizontal direction (x-axis) between two points on the line or surface.

Changing the slope of a train's wheels can have both positive and negative effects on the train's overall performance.

On the positive side, increasing the slope of the wheels can improve the train's stability and safety as it goes around curves. This is because the inward slope of the wheels helps to counteract the centrifugal force that pushes the train outward as it goes around curves. By increasing the slope of the wheels, this counteracting force can be increased, which can help prevent derailments and improve the overall safety of the train.

On the negative side, increasing the slope of the wheels can decrease the train's efficiency at producing speed. This is because the slope of the wheels creates additional friction between the wheels and the track, which can slow the train down and require more energy to maintain speed. As the slope of the wheels increases, this friction also increases, which can make the train less efficient at producing speed and more costly to operate.

Therefore, there is a trade-off between stability and speed when it comes to the slope of a train's wheels. Train designers must find the optimal balance between these two factors to ensure that the train is both stable and efficient.

Answers

Step-by-step explanation:

Since the new poison kills half the population every 2 months, we can say that the remaining half will survive for another 2 months. Therefore, after 2 months, the rodent population will be half of 1,000,000, which is 500,000.

After another 2 months, the remaining half of the 500,000 will survive, which is 250,000.

After another 2 months, the remaining half of the 250,000 will survive, which is 125,000.

After 6 months, the rodent population will be 125,000.

Since 12 months is six 2-month periods, we can repeat this process again. After another 2 months, the rodent population will be 62,500.

After another 2 months, the rodent population will be 31,250.

After another 2 months, the rodent population will be 15,625.

Therefore, after 12 months, the rodent population will be 15,625.

There are 6 people in a group. Their names are selected randomly and they act independently. a) Calculate probability that the first person arriving has the same name as 1 or more people. b) Calculate probability that there are people in the group with a same name.

Answers

There are 6 people in a group. Their names are selected randomly and they act independently. The probability that the first person arriving has the same name as 1 or more people is 0. The probability that there are people in the group with the same name is 98.46%.

The probability that the initial arrival shares a name with one or more others is 0 percent. This is because the first person arriving has no one to compare their name with, so there is no chance that they will have the same name as someone else.

The probability that there are people in the group with the same name can be calculated using the formula

P(same name) = 1 - P(different names).

The probability of everyone having different names is calculated by multiplying the probabilities of each person having a different name from the previous person. This can be represented as

(6/6) * (5/6) * (4/6) * (3/6) * (2/6) * (1/6) = 0.0154.

When given a problem such as (5 + 3i)(7 – 4i), what are 2 important processes to remember to simplify your answer?

Answers

To simplify the expression (5 + 3i)(7 – 4i), two important processes to remember are to use the distributive property to multiply the real parts and imaginary parts separately and simplify the resulting expression by combining any like terms.

Use the distributive property:

For the expression (5 + 3i)(7 – 4i),

(5 + 3i)(7 – 4i) = 5(7) + 5(-4i) + 3i(7) + 3i(-4i)

= 35 - 20i + 21i - 12i^2

Note that i^2 = -1,

35 + i(21 - 20) - 12(-1) = 47 + i(41)

Simplify the resulting expression:

After using the distributive property to expand the expression, we can simplify the resulting expression by combining any like terms. In this case, there are no like terms to combine, so our final answer is:

A labour economist aims to estimate the variance of unemployed workers' mathematic test scores. Assume that a random sample of 18 scores had a sample standard deviation of 10.4. To form a 90% confidence interval for the population varianceis The confidence interval is exactly between 46.64 and 202.07. The correct answer is option (a)



Find the degrees of freedom (df) by subtracting 1 from the sample size:
df = n - 1 = 18 - 1 = 17

Find the chi-square values for the 90% confidence interval using a chi-square table or calculator. The lower value corresponds to the 5th percentile (0.05) and the upper value corresponds to the 95th percentile (0.95):
χ² lower = 27.488
χ² upper = 8.672

Calculate the lower and upper limits of the confidence interval using the formula:
CI lower = (df * s²) / χ²_upper
CI upper = (df * s²) / χ²_lower

Where s² is the sample variance (the square of the sample standard deviation):
s² = 10.4² = 108.16

Plugging in the values:
CI lower = (17 * 108.16) / 27.488 = 46.64
CI upper = (17 * 108.16) / 8.672 = 202.07

The 90% confidence interval for the population variance is between the lower and upper limits:
CI = (46.64, 202.07)

Therefore, the correct answer is option (a) The confidence interval is exactly between 46.64 and 202.07.

Step-by-step explanation:

What is dilation?

The original image is DEFG. It is called the pre-image

The dilated image is D'E'F'G' and is called image

A transformed image has the coordinates labeled with a '

In this case the transformed image is a dilation of the original pre-image. A dilated image is a cop.y of the pre-image but with either an expansion or a compression

If the image is larger than the pre-image it is an expansion, if smaller than the pre-image then it is a compression

With dilation, comes a scale factor which indicates how much a pre-image has been expanded or compressed

Solution

If you look at the two images, take any side in the pre-image and compare its length with the corresponding side you can find the scale factor

Here if you take a side, say DE = 4 and look at the corresponding side D'E' = 6you see that the DE side has been expanded with a scale factor of 6/4 = 3/2

This scale factor applies to all sides, so you need to take only one side to find the scale factor

Answers

This is a horizontal line passing through the point (-9, -3).

What is Slope?

Slope is a measure of how steep a line is. It is defined as the ratio of the change in the y-coordinates of two points on a line to the change in the x-coordinates of those same points. In other words, slope is the amount by which the y-coordinate changes when the x-coordinate changes by 1 unit.

Since the given line is vertical, its slope is undefined. The slope of a line perpendicular to it is zero. Therefore, the slope of the graph of f is zero.

We can use the point-slope form of a linear equation to write the equation of the line passing through the point (-9, -3) with a slope of zero:

y - (-3) = 0(x - (-9))

Simplifying, we get:

y + 3 = 0

Subtracting 3 from both sides, we get:

y = -3

Answers

We can write tanz in terms of secz using the Pythagorean Identity as:
tanz = -sqrt(sec^2z - 1)

Part 1 of 2:
The Pythagorean Identity states that sin^2z + cos^2z = 1. We can use this identity to write tan^2z in terms of sec^2z.

First, let's rearrange the Pythagorean Identity to isolate cos^2z:
cos^2z = 1 - sin^2z

Next, we can divide both sides of the equation by cos^2z to get:
1 = sec^2z - (sin^2z)/(cos^2z)

Since tan^2z = (sin^2z)/(cos^2z), we can substitute this into the equation:
1 = sec^2z - tan^2z

Finally, we can rearrange the equation to isolate tan^2z:
tan^2z = sec^2z - 1

Now, let's consider the case when z is in Quadrant II. In this quadrant, tanz is negative and secz is negative. Therefore, we can write:
tanz = -sqrt(sec^2z - 1)

Part 2 of 2:
In the case when z is in Quadrant IV, tanz is negative and secz is positive. Therefore, we can write:
tanz = -sqrt(sec^2z - 1)

The expression cannot be factored over integers since the roots are not integers.

1. This is an alternating series, and therefore, the series converges by the Alternating Series Test. This is because the sequence of the absolute value of the terms, {|3n+5|}^(1/3), is a monotonically decreasing sequence, and it is bounded. To determine how many terms are necessary to get within 0.05 of the sum, we use the formula:

Sn≈s​[infinity]​+a1r1/1−r

where a1 is the first term, and r is the common ratio. In this case, we have a1 = (3+5)^(1/3) = 2, and r = (-1)^(1/3) = -1. Thus, Sn ≈ 2 + (2)(-1)/1 - (-1) = 4.

Since the series is alternating, it is absolutely convergent.

11. The distance round a circular hut is 17.6 m. What is the area of its floor?
12.A string measures 220 cm. Its two ends are joined to form a circle. What area
does the string enclose?
13. The area of a circular mat is 1.54 m². What is its circumference?

Answers

11. The area of the floor is 24. 62 m²

12. The area of the enclosed string is 3, 853. 09cm²

13. The circumference of the circular mat is  4.39m

How to determine the area

The formula for the area of a circle is expressed with the equation;

A = πr²

Where;

A is the area.π takes the value 3.14r is the radius of the circle.

Also, circumference of a circle is 2πr

For a circumference of 17. 6m, we have

17. 6 = 2×3.14r

r = 2. 80

Substitute the value

Area = 3.14 × (2. 80)²

Area = 24. 62 m²

For the string, circumference = 220cm

220 = 2× 31.4r

r = 35. 03 cm

Area of the enclosed string = 3.14 × (35. 03)²

Area = 3, 853. 09cm²

For the circular mat

1.54 = 3.14r²

r² = 0. 49

Take the square root

r = 0. 7m

Circumference = 2× 3.14 × 0. 7 = 4.39m

Linier ALgebra : Let W E R^nxn, s E R, and λ an eigenvalue of W. Prove that λ – s is an eigenvalue of W – sλ. (As usual, I = Inxn denotes the n x n identity matrix.)

Answers

$\lambda - s$ is an eigenvalue of W – s$\lambda$ and $\mathbf{v}$ is the corresponding eigenvector.



Linear Algebra: Let W $\in$ $\mathbb{R}^{n \times n}$, s $\in$ $\mathbb{R}$, and $\lambda$ an eigenvalue of W. To prove that $\lambda$ – s is an eigenvalue of W – s$\lambda$, we will use the definition of eigenvalues and eigenvectors:

An eigenvalue $\lambda$ of a square matrix A $\in$ $\mathbb{R}^{n \times n}$ is a scalar such that there exists a nonzero vector $\mathbf{v} \in \mathbb{R}^n$ for which the following equation holds:

A$\mathbf{v}$ = $\lambda \mathbf{v}$

Therefore, we can rearrange the equation to show that W – s$\lambda$ $\mathbf{v}$ = $(\lambda -s) \mathbf{v}$, which implies that $\lambda - s$ is an eigenvalue of W – s$\lambda$ and $\mathbf{v}$ is the corresponding eigenvector.

The volume of a cylinder is 180 pi cubic inches and the radius of the cylinder is 3 inches. what is the height of the cylinder 

Answers

Using the formula of the cylinder we know that the height of the given cylinder is 6.36 inches.

What is a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid.

It is regarded as a prism with a circle as its base in basic geometry.

In several contemporary fields of geometry and topology, a cylinder can alternatively be characterized as an infinitely curved surface.

So, the cylinder formula for the volume is:

V = πr²h

Now, substitute the values as follows:

V = πr²h

180 = 3.14*3²h

180 =  28.26h

180/28.26 = h

6.36 = h

Therefore, using the formula of the cylinder we know that the height of the given cylinder is 6.36 inches.
