Find the standard matrix of the given linear transformation from R2R2 to R2R2 Projection onto the line y=2xy=2x So basically, I got the standard matrix to be (1200),(1020), my question is: is this actually right? I have been looking online and it appears that maybe I am wrong?
The standard matrix of the linear transformation given in the question is
= 1/ 5 [ 1 2 ]
[ 2 4 ]
The direction vector of the given line is , v = ( 1 ,2 ).
So the projection of the line will be,
projection ( x ,x ) = ( (x , y ) . v / v^2 )v
= ( ( x + 2y)/5 ) v
Therefore, the required standard matrix will be ,

A bus makes a stop at 2:30, letting off 15 people and letting on 9. The
bus makes another stop ten minutes later to let off 4 more people.
How many more or fewer people are on the bus after the second stop
compared to the number of people on the bus before the 2:30 stop?
After the second stop, there are 10 fewer people on the bus compared to the number of people on the bus before the 2:30 stop.
Before the 2:30 stop, the bus let off 15 people and let on 9 people. The total change in the number of people at that stop is -15 (let off) + 9 (let on) = -6.
Therefore, there are 6 fewer people on the bus after the 2:30 stop compared to before that stop.
Ten minutes later, the bus makes another stop and lets off 4 more people. This additional change needs to be considered.
Since the previous calculation only accounted for the changes up until the 2:30 stop, we need to adjust the total change by including the subsequent stop.
Adding the change of -4 (let off) to the previous total change of -6, we get a new total change of -10.
Therefore, after the second stop, there are 10 fewer people on the bus compared to the number of people on the bus before the 2:30 stop.

1,0008 = 10w
W =
The simplified equation 1,0008 = 10w can be represented as 1024 = 10w, and we can determine that w is equivalent to 24 by comparing the exponents. This implies that the value of w required to make the equation true is 24.
To simplify the equation\(1,000^{8}\)= \(10^{w}\), we need to recognize that 1,000 is equal to \(10^{3}\). Therefore, we can rewrite the equation as \((10^{3})^{8}\) = \(10^{w}\)
Using the property of exponents, when raising a power to another power, we multiply the exponents. Applying this property, we get \(10^{3*8}\) = \(10^{w}\).
Simplifying further, we have \(10^{24}\) = \(10^{w}\).
In order for two exponential expressions to be equal, their bases must be the same. In this case, both bases are 10. Therefore, we can conclude that the exponents must also be equal.
Hence, w = 24.
The simplified equation 1,000^8 =\(10^{w}\)can be expressed as \(10^{24}\) = \(10^{w}\), and by comparing the exponents, we find that w is equal to 24. This means that the value of w that makes the equation true is 24.

A firm makes two products X and Y, and has a total production capacity of 9 tones per day, X and Y requiring the same production capacity. The firm has a permanent contract to supply at least 2 tones of X and at least 3 tones of Y per day to another company. Each tone of X requires 20 machine hours of production time and each tone of Y requires 50 machine hours of production time. The daily maximum possible number of machine hour is 360. All the firm’s output can be sold, and the profit made is birr 80 per tone of X and birr 20 per tone of Y. it is required to determine the production schedule for maximum profit.
The production schedule for maximum profit is; X = 3 and Y = 6 with a maximum profit of $960
How to solve Linear Programming problems?We are told that two products X and Y, has a total production capacity of 9 tones per day, X and Y requiring the same production capacity
The firm has a permanent contract to supply at least 2 tones of X and at least 3 tones of Y per day to another company.
Let product A be x and product B be y. Therefore we have the following inequalities and constraints as;
x + y ≤ 9
x ≥ 2
y ≥ 3
Now, we are told that each tonne of A requires 20 machine hours of production time and each tonne of B requires 50 machine hours of production time. The daily maximum possible number of machine hours is 360. Thus, we have;
20x + 50y ≤ 360
Wea re told that all the firm's output can be sold and the profit made is $80 per tonne of A and $120 per tonne of B. Thus, we have the inequality as;
Z = 80x + 120y maximize
The solution from the graph attached is;

Find the equation for the line that passes through (-1, 10) that has slope 5/7. You do not need to simplify.
Give your answer in point-slope
Answer:
y = (5/7)x + (75/7)
Step-by-step explanation:
If you ever find yourself in a math class where you have to write the equation of a line that goes through a certain point and has a certain slope, don't panic. There is a simple formula that can help you out. It's called the point-slope form and it looks like this:
y - y1 = m (x - x1)
It may look scary, but it's actually pretty easy to use. All you have to do is plug in the values that you know and solve for the ones that you don't. For example, let's say you have a line that passes through the point (-1, 10) and has a slope of 5/7. You can use the point-slope form to write the equation of the line like this:
y - 10 = (5/7) (x - (-1))
See? That wasn't so bad. Now you can simplify the equation by distributing the 5/7 and adding 10 to both sides. You get:
y = (5/7)x + (75/7)
And that's it! You have written the equation of the line in slope-intercept form, which is another way of writing the equation of a line. You can check your answer by plugging in the values of x and y from the original point and seeing if they make the equation true. If they do, you're good to go. If not, you made a mistake somewhere and you should go back and fix it.
Congratulations! You have learned how to use the point-slope form to write the equation of a line. Now you can impress your math teacher and your friends with your skills. Remember, with great power comes great responsibility.

The sample proportion based on the question that we have here is 0.85
What is sample proportion?
The sample proportion (p) indicates the percentage of people in a sample who exhibit a particular quality or attribute. Divide the number of individuals (or items) who have the desired attribute by the overall sample size to obtain the sample proportion.
P=X/N, where X represents the number of successes and N represents the sample size, yields the sample proportion.
Hence from the question, we see that 85% of the passengers booked for flights actually show up. hence the proportion is 0.85.
