what is the projection of u onto v with "U" having points (-9,-5) and "V" having points (-6,5)
The projection of u onto v is proj_v(u) = (u•v)/(||v||²) * v = (29/61) * (-6,5) = (-174/61, 145/61).
Explain the term projection
Projection is the process of representing a three-dimensional object or scene onto a two-dimensional surface. It involves the use of mathematical principles to create a flat image that accurately depicts the shape and position of the object or scene. Projections are widely used in fields such as engineering, architecture, and computer graphics to create visual representations of complex structures and designs.
According to the given information
The projection of a vector u onto a vector v is given by the formula proj_v(u) = (u•v)/(||v||²) * v, where u•v is the dot product of u and v, and ||v|| is the magnitude of v.
In this case, u = (-9,-5) and v = (-6,5). The dot product of u and v is u•v = (-9)(-6) + (-5)(5) = 54 - 25 = 29. The magnitude of v is ||v|| = √((-6)² + (5)²) =
√(36 + 25) = √61.
So the projection of u onto v is proj_v(u) = (u•v)/(||v||²) * v = (29/61) * (-6,5) = (-174/61, 145/61).

the vegetable garden is 24 square feet larger than the herb garden. The area of the square vegetable garden is equal to the length of one side squared.
what is larger than ?
"larger than" is a comparative term used to describe a situation where one thing has a greater size, quantity, value, or magnitude than another thing. It is used to indicate a comparison between two or more objects or quantities.
In the given question,
The area of the square vegetable garden is equal to the length of one side squared. Each side of the square garden is 6 feet long, so the area of the vegetable garden is:
6 feet × 6 feet = 36 square feet
The area of the rectangular herb garden is equal to its length multiplied by its width. The length of the herb garden is 4 feet and the width is 3 feet, so the area of the herb garden is:
4 feet × 3 feet = 12 square feet
To find the difference in area between the two gardens, we subtract the area of the herb garden from the area of the vegetable garden:
36 square feet - 12 square feet = 24 square feet
Therefore, the vegetable garden is 24 square feet larger than the herb garden.

One of the legs of a right triangle measures 16 cm and the other leg measures 2 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
[tex]2\sqrt{65}[/tex] cm, decimal form is about 16.1 cm
Step-by-step explanation:
Use the pythagorean theorem:
A^2 + B^2 = C^2
A and B are legs, c is hypotenuse
First leg is 16, second leg is 2
Plug it in:
16^2 + 2^2 = hypotenuse^2
256 + 4 = hypotenuse ^2
260 = h^2
[tex]\sqrt[2]{260}[/tex] = h
To simplify the square root of 260, we can factor 260 into its prime factors:
260 = 2 x 2 x 5 x 13
Then, we can take out the pairs of identical factors from under the square root symbol:
sqrt(260) = sqrt(2 x 2 x 5 x 13)
= sqrt(2 x 2) x sqrt(5) x sqrt(13)
= 2sqrt(65)

Toshi predicted that he will perform a card trick successfully 95% of the time. He went on to perform the card trick successfully 24 out of 30 times. How did Toshi’s prediction compare with his actual results?
Toshi's actual results were significantly different from his prediction. Specifically, his actual success rate of 80% was lower than his predicted success rate of 95%.
What is probability?Probability is a way to gauge how likely or unlikely something is to happen. It is denoted by a number between 0 and 1, with 1 denoting a certain event and 0 denoting an impossibility.
According to question:Toshi's prediction was that he would perform the card trick successfully 95% of the time. This means that out of 100 card tricks, he expects to perform the trick successfully in 95 of them. We can represent this mathematically by:
P(success) = 0.95
This is the probability of success for one card trick.
Toshi actually performed the card trick 30 times and was successful in 24 of them. We can represent this as:
P(actual success) = 24/30 = 0.8
This is the proportion of successful card tricks that Toshi actually performed.
To compare Toshi's prediction with his actual results, we can use probability theory. The probability of getting exactly x successes in n trials when the probability of success is p is given by the binomial distribution formula:
P(x) = (n choose x) * pˣ * [tex](1-p)^(n-x)[/tex]
In this case, we can use the formula to calculate the probability of getting exactly 24 successes in 30 trials if Toshi's prediction of 95% success rate is accurate. This is given by:
P(24 successes) = (30 choose 24) * 0.95²⁴ * 0.05⁶ ≈ 0.0045
This means that if Toshi's prediction is accurate, the probability of getting exactly 24 successes in 30 trials is very low (less than 0.5%).
Therefore, we can conclude that Toshi's actual results were significantly different from his prediction. Specifically, his actual success rate of 80% was lower than his predicted success rate of 95%.

B. Find the area of the rectangle. Show your work
A. The area of the rectangle is 29.16 square inches.
B. The width of the rectangle is 2.7 inches and the height (or length) is 10.8 inches
What is rectangle?A parallelogram in which each pair of adjacent sides is perpendicular is referred to as a rectangle.
We should utilize "w" to address the width and "l" to address the length of the square shape.
A. Since the width equals one quarter of the length, we are able to write:
w = (1/4)l
We also know that the perimeter of the rectangle is 27 inches, and
the formula for the perimeter of a rectangle is:
P = 2l + 2w
Substituting the first equation into the second equation, we get:
P = 2l + 2(1/4)l
27 = 2.5l
l = 10.8
Now that we know the length, we can use the first equation to find the width:
w = (1/4)l
w = (1/4)(10.8)
w = 2.7
As a result, the rectangle has a width of 2.7 inches and a height of 10.8 inches.
B. To find the area of the rectangle, we can use the formula:
Area = length *width
Substituting the values we found above, we get:
A = (2.7)*(10.8)
A = 29.16

what order do they go in?
At sunrise, shadows are longest and point towards the west as the sun rises in the east. Therefore, the correct order would be:
Longest shadows of the day, and they point to the west → shadows gradually become shorter → very short shadows or no shadows → shadows gradually become longer → longest shadows of the day, and they point to the east.
What is the shadows about?As the sun moves across the sky, shadows change in length and direction, reaching their shortest length at noon when the sun is directly overhead. After noon, the sun starts to move towards the west, and shadows gradually become longer until sunset when they are longest again, but this time pointing towards the east as the sun sets in the west.
Therefore, correct order of descriptions of shadows during the day, from sunrise to sunset, would be:
Very short shadows or no shadows - This occurs during sunrise when the sun is low on the horizon and its rays are nearly vertical, resulting in very short shadows or no shadows at all.Shadows gradually become longer - As the sun rises higher in the sky, shadows start to lengthen gradually.Longest shadows of the day, and they point to the west - During late morning or early afternoon, shadows are at their longest and they point towards the west, opposite to the direction of the sun.Shadows gradually become shorter - As the sun starts to descend towards the horizon in the late afternoon, shadows gradually become shorter.Longest shadows of the day, and they point to the east - During sunset, shadows are again at their longest, but this time they point towards the east, following the direction of the setting sun.Read more about shadows here:

a sample of 1600 computer chips revealed that 64% of the chips do not fail in the first 1000 hours of their use. the company's promotional literature claimed that above 61% do not fail in the first 1000 hours of their use. is there sufficient evidence at the 0.02 level to support the company's claim? state the null and alternative hypotheses for the above scenario.
The test statistic (3.46) is greater than the critical value (2.05), we reject the null hypothesis and conclude that there is sufficient evidence at the 0.02 level to support the company's claim that above 61% of the chips do not fail in the first 1000 hours of their use.
The null hypothesis for this scenario is that the proportion of computer chips that do not fail in the first 1000 hours of their use is equal to or less than 61%, while the alternative hypothesis is that the proportion is greater than 61%. Mathematically:
H0: p ≤ 0.61
Ha: p > 0.61
where p is the true proportion of computer chips that do not fail in the first 1000 hours of their use.
To test this hypothesis, we can use a one-tailed z-test for proportions. Using the given sample information, we can calculate the test statistic as:
z = (0.64 - 0.61) / sqrt((0.61 * 0.39) / 1600) = 3.46
where 0.39 is the complement of 0.61, and sqrt denotes the square root. The critical value for a one-tailed test at the 0.02 level of significance is 2.05.
Since the test statistic (3.46) is greater than the critical value (2.05), we reject the null hypothesis and conclude that there is sufficient evidence at the 0.02 level to support the company's claim that above 61% of the chips do not fail in the first 1000 hours of their use.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{314-348}{6-4}\\m=\frac{-34}{2}\\m= -17[/tex]
(a).now,equation of line ,y=mx+c
⇒y= -17x+420..(i)
(b). for 2012,x=2012
now value of x is substitute in (i),
⇒y= -(17*2012)+420
⇒y = -34204+420
⇒y= -33784.
