find projvu and projuv. use the euclidean inner product. u = (5, −7, 1), v = (1, −1, 0)
Answers
The projection of vector v onto vector u (projvu) (6, -6, 0).
where v • u represents the dot product of vectors v and u, and ||u||^2 represents the squared magnitude of vector u.
we use the formula:
projvu =\( (v • u / ||u||^2) * u\)
Using the given values of u and v, we can compute their dot product:
\( v • u = (5*1) + (-7*-1) + (1*0) = 12\)
We can also find the squared magnitude of vector u:
\( ||u||^2 = (5^2 + (-7)^2 + 1^2) = 75\)
Plugging these values into the formula for projvu, we get:
projvu =\( (12 / 75) * (5, -7, 1) = (0.16, -0.22, 0.03)\)
Therefore, the projection of vector v onto vector u is approximately (0.16, -0.22, 0.03).
To find the projection of vector u onto vector v (projuv), we use the same formula but with the vectors reversed:
projuv = \( (u • v / ||v||^2) * v\)
We can compute the dot product of u and v as before:
\( u • v = (5*1) + (-7*-1) + (1*0) = 12\)
We can also find the squared magnitude of vector v:
\( ||v||^2 = (1^2 + (-1)^2 + 0^2) = 2\)
Plugging these values into the formula for proj uv, we get:
projuv =\( (12 / 2) * (1, -1, 0) = (6, -6, 0)\)
Therefore, the projection of vector u onto vector v is (6, -6, 0).

Sateen fabric costs $6 per yard and quilting fabric costs $4 per yard. Which system of equations can be used to find the amount x (in yards) of regular quilting fabric and the amount y (in yards) of sateen fabric she purchased?
Answers
Answer:
\(\left \{ {{6x+4y=76} \atop {x+y=16}} \right.\)
Step-by-step explanation:
1) if (according to the condition) the amount of quilting is 'x' and the amount of sateen is 'y', then the price of the quilting fabric is 6*x and the price of then sateen fabric is 4*y;
2) the 76$ she spends can be written as 6x+4y=76;
3) total of 16 yards can be written as x+y=16;
4) finally, the required system is:
\(\left \{ {{6x+4y=76} \atop {x+y=16}} \right.\)
A system of equations is a collection of two or more equations with a same set of unknowns. 4x+6y=76, x+y=16 are required system of equations.

The angle between 0∘ and 360∘ that is coterminal with the −252∘ angle is degrees.
Answers
The angle coterminal with -252° between 0° and 360° is 108°.
To find the angle between 0° and 360° that is coterminal with the -252° angle, we can add or subtract multiples of 360° until we get an angle within the desired range.
Since the given angle is negative, we can add 360° to it repeatedly until we get a positive angle:
-252° + 360° = 108°
Therefore, the angle between 0° and 360° that is coterminal with the -252° angle is 108°.
Coterminal angles are angles that have the same initial and terminal sides but may differ in the number of complete revolutions made. In this case, by adding 360° to the given angle, we obtain an angle that falls within the desired range.

Round this number to the

5.460
Answers
When dealing with figures that are round to the closest tenth, such as 5.460, it may be simpler to round the number to 5.5.
How is the rounding off done?We must look at the hundredth digit, which is 6, in order to round 5.460 to the nearest tenth. We must round up to the next higher digit, which is 4, because 6 is bigger than or equal to 5. The result is 5.5, which has been rounded to the nearest tenth.
If the digit in the hundredths place is 5 or above, we round up the tenths digit; if it is less than 5, we leave the tenths digit as is. This is the basic rule we use when rounding numbers to the closest tenth. In this instance, we round up the tenths digit from 4 to 5 because the hundredths digit is 6. When we want to streamline calculations or explain numbers in a more understandable or natural way, rounding might be helpful.

Question 1
A pair of running shoes is on sale for $125.99. If the sale price is discounted 9% from the original price, what is the
original price?
Answers
Answer:
$138.45
Step-by-step explanation:
The original price was 100% of the original price since 100% is the whole thing.
The price was discounted by 9%.
100% - 9% = 91%
That means the discounted price is 91% of the original price.
Let x = original price.
91% of x = $125.99
0.91x = 125.99
x = 125.99/0.91
x = 138.45

In a science lab, a number of rock samples are weighed. If the scientist finds one of the rocks to weigh 6.5 pounds and this is 23.3% of the total weight of all of the rocks, what is the weight of all of the rocks
Answers
The scientist concludes that the weight of a 6.5 pounds rock is equal to 23.3% of the total weight of all the rocks. Hence the total weight of all rocks is 27.9 pounds.
Given that:
Weight of one rock= 6.5 pounds
A 6.5-pound rock weighs the same as 23.3 percent of the overall weight.
Let the total weight of all the rocks is = A
So, by using the given statement:
6.5= 23.3% of A
6.5= 23.3% × A
6.5= (23.3/100)×A
(23.3/100)×A = 6.5
Multiplying both sides by (100/23.3) we obtain,
A= 6.5×(100/23.3)
A= 6500/233
A= 27.9
Therefore, the overall weight of all the rocks is 27.9 pounds.

Step-by-step explanation:
I did the test too :)
The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.
To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.
Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:
For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup
For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup
For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup
For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup
From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.
Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

A garden is shaped in the form of a regular heptagon (seven-sided), MNSRQPO. A circle with center T and radius 25m circumscribes the heptagon as shown in the diagram. The area of ΔMSQ is left for a children's playground, and the rest of the garden is planted with flowers. Find the area of the garden planted with flowers.
Answers
The relationship between the sides MN, MS, and MQ in the given regular heptagon is \(\dfrac{1}{MN} = \dfrac{1}{MS} + \dfrac{1}{MQ}\)
The area to be planted with flowers is approximately 923.558 m²
The reason the above value is correct is as follows;
The known parameters of the garden are;
The radius of the circle that circumscribes the heptagon, r = 25 m
The area left for the children playground = ΔMSQ
Required;
The area of the garden planted with flowers
Solution:
The area of an heptagon, is;
\(A = \dfrac{7}{4} \cdot a^2 \cdot cot \left (\dfrac{180 ^{\circ}}{7} \right )\)
The interior angle of an heptagon = 128.571°
The length of a side, S, is given as follows;
\(\dfrac{s}{sin(180 - 128.571)} = \dfrac{25}{sin \left(\dfrac{128.571}{2} \right)}\)
\(s = \dfrac{25}{sin \left(\dfrac{128.571}{2} \right)} \times sin(180 - 128.571) \approx 21.69\)
\(The \ apothem \ a = 25 \times sin \left ( \dfrac{128.571}{2} \right) \approx 22.52\)
The area of the heptagon MNSRQPO is therefore;
\(A = \dfrac{7}{4} \times 22.52^2 \times cot \left (\dfrac{180 ^{\circ}}{7} \right ) \approx 1,842.94\)
\(MS = \sqrt{(21.69^2 + 21.69^2 - 2 \times 21.69 \times21.69\times cos(128.571^{\circ})) \approx 43.08\)
By sine rule, we have
\(\dfrac{21.69}{sin(\angle NSM)} = \dfrac{43.08}{sin(128.571 ^{\circ})}\)
\(sin(\angle NSM) =\dfrac{21.69}{43.08} \times sin(128.571 ^{\circ})\)
\(\angle NSM = arcsin \left(\dfrac{21.69}{43.08} \times sin(128.571 ^{\circ}) \right) \approx 23.18^{\circ}\)
∠MSQ = 128.571 - 2*23.18 = 82.211
The area of triangle, MSQ, is given as follows;
\(Area \ of \Delta MSQ = \dfrac{1}{2} \times 43.08^2 \times sin(82.211^{\circ}) \approx 919.382^{\circ}\)
The area of the of the garden plated with flowers, \(A_{req}\), is given as follows;
\(A_{req}\) = Area of heptagon MNSRQPO - Area of triangle ΔMSQ
Therefore;
\(A_{req}\)= 1,842.94 - 919.382 ≈ 923.558
The area of the of the garden plated with flowers, \(A_{req}\) ≈ 923.558 m²

According to the information we can infer that Dora's conclusion may be incorrect because the information provided only states that the number of people who spent time reading falls within specific ranges (0-2 hours, 2-4 hours, and 2-10 hours), but it does not give a specific count for those who spent at least 4 hours. Therefore, Dora's assumption that "most people spent at least 4 hours a week reading" is not supported by the given data.
How to calculate the range of the time that Dora's friends spent reading?The range of the time spent reading cannot be determined from the information provided because the ranges are overlapping. For example, a person who spent exactly 2 hours reading could fall into both the first range (0-2 hours) and the second range (2-4 hours). Without more specific data or non-overlapping ranges, it is not possible to determine the exact range of time spent reading.
To estimate the mean time spent reading by Dora's friends, we can calculate the midpoint of each range and use it as an approximate value. The midpoint for the first range (0-2 hours) is 1 hour, for the second range (2-4 hours) is 3 hours, and for the third range (2-10 hours) is 6 hours. We can then calculate the estimated mean by taking the weighted average of these midpoints using the respective number of people as weights.
Estimated mean = [(4 * 1) + (5 * 3) + (11 * 6)] / (4 + 5 + 11) = 4.53 hours (approximately)
So, an estimate of the mean time spent reading by Dora's friends is approximately 4.53 hours.

It is possible, however, that some individuals in the sample may have had heights that were close to the average, either slightly above or slightly below it.
It is unlikely that any individual in Dr. Vickers' sample (or anyone at all) would have had the exact average number of feet, as the average is typically calculated as a mathematical mean that may or may not correspond to an actual measurement.
For example, if the average (mean) number of feet in a sample of 10 people is calculated to be 6 feet, it is highly unlikely that any individual in the sample actually has a height of exactly 6 feet. Rather, the average is a statistical summary of the data that provides insight into the central tendency of the sample as a whole.

brooke found the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form as follows
Answers
Answer:
The equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is \(\mathbf{y=-4x-3}\)
Step-by-step explanation:
Equation of line passing through the points (-7,25) and (-4,13) in slope-intercept form.
The general equation of slope-intercept form is: \(y=mx+b\)
First we need to find slope
The formula used for finding slope is: \(Slope=\frac{y_2-y_1}{x_2-x_1}\)
We are given: \(x_1=-7, y_1=25, x_2=-4, y_2=13\)
Putting values in formula and finding slope
\(Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{13-25}{-4-(-7)}\\Slope=\frac{13-25}{-4+7}\\Slope=\frac{-12}{3}\\Slope=-4\)
So, slope m= -4
Now finding y-intercept
Using slope m=-4 and point (-7,25) we can find y-intercept
\(y=mx+b\\25=-4(-7)+b\\25=28+b\\b=25-28\\b=-3\)
So, y-intercept b =-3
Now, the equation of required line having slope m=-4 and y-intercept b=-3 is:
\(y=mx+b\\y=-4x-3\)
So, the equation of the line passing through the points (-7,25) and (-4,13) in slope-intercept form is \(\mathbf{y=-4x-3}\)
