Answer 1

Answer:

-39

Step-by-step explanation:

||u|| = sqrt(5² + (-12)²)

= sqrt(25 + 144)

= sqrt(169)

= 13

||cu|| = c ||u||

c = -3

c ||u|| = -3 × 13 = -39

Answer 2

Answer:

-39

Step-by-step explanation:

The magnitude of a vector is given by

|| u|| = sqrt( x^2 + y^2)

       = sqrt( 5^2 + (-12)^2)

       = sqrt(25+144)

      = sqrt(169)

     = 13

We are then multiplying by a scalar

||cu|| = -3*13 = -39

if the number of hot lunches sold at school this week was 1,350 and the relative frequency on friday was 0.22, how many lunches were sold on friday?

Answers

296 hot lunches were sold on Friday.

The number of hot lunches sold on Friday can be calculated by multiplying the total number of hot lunches by the relative frequency on Friday:

Hot lunches sold on Friday = 1,350 * 0.22 = 296

What is Relative frequency ?

Relative frequency is a measure of the number of times an event occurs in a sample, expressed as a proportion of the total number of events. To find the number of hot lunches sold on Friday, we multiply the total number of hot lunches sold in the week by the relative frequency of Friday. This gives us the number of hot lunches sold on Friday, which is 296 in this case. Understanding relative frequency is important in statistics as it helps to summarize data and understand the distribution of events.

Answers

The constant proportionality between the x-coordinates and y-coordinates of these four points is 12.

What is Proportionality?

Proportionality refers to the relationship between two quantities that change in a consistent and predictable way. In a proportional relationship, when one quantity changes, the other quantity changes in a constant ratio or proportion to the first.

Assuming that you want to find the constant proportionality between the x-coordinates and y-coordinates of these four points:

First, we can calculate the ratios of the y-coordinates to the x-coordinates for each point:

For (3,36): y/x = 36/3 = 12

For (5,60): y/x = 60/5 = 12

For (6,72): y/x = 72/6 = 12

For (7,84): y/x = 84/7 = 12

We can see that the ratios are all equal to 12. Therefore, the constant proportionality between the x-coordinates and y-coordinates of these four points is 12.

Note that if you had asked for the constant proportionality between the differences in the y-coordinates and the differences in the x-coordinates of these points, the answer would be different. That constant proportionality is known as the slope of the line passing through these points.

Answers

A perpendicular bisector is a bisector to a line segment which makes an angle of 90° with the line segment.

A perpendicular bisector is usually constructed by using a compass and a straightedge. It can also be constructed using a protractor.

Construction of perpendicular bisector using a compass and straightedge.

First draw the line segment, lets say AB.Using your compass measure a radius which is more than half of the line segment. We can measure this by keeping the compass ant point A, and take a measure beyond the mid point.Now place the compass at A, and draw an arc with the measured radius.Place the compass at B and draw an arc with the same radius.The arcs meet above and below the line. Take the straightedge and draw a line which passes through both the intersection of arcs.

Thus we get the perpendicular bisector.

Consider this system of equations.

p=2n

p-5 = 1. 5n

What value of n makes the system of equations true?

Enter your answer in the box.

Answers

Therefore, the value of n that makes the system of equations true is n = 10.

Given:

p = 2n

p - 5 = 1.5n

Substituting the value of p from the first equation into the second equation, we have:

2n - 5 = 1.5n

Next, we can solve for n by subtracting 1.5n from both sides of the equation:

2n - 1.5n - 5 = 0.5n - 5

Simplifying further:

0.5n - 5 = 0

Adding 5 to both sides of the equation:

0.5n = 5

Dividing both sides by 0.5:

n = 10

Therefore, the value of n that makes the system of equations true is n = 10.

Answers

Average number of planes that will stack up waiting to land:  This can vary greatly depending on the size of the airport, the number of flights per day, and the number of runways available.

What is average?

Average, mean, median, and norm all refer to something that sits in the middle. The average is the ratio created by dividing the total number of figures in a set by the total number of figures.

To determine the average number of planes that will stack up waiting to land, we need to know the rate at which planes arrive at the airport and the rate at which they are able to land.

Generally, an airport can expect to experience a queue of up to 10 planes waiting to land at peak times.

Average time a plane must wait in line before it can land: This also varies significantly depending on the airport and the conditions. Generally, a plane must wait an average of 5-7 minutes before it is able to land.

Average time it takes a plane to clear the runway once it has notified the airport that it is in the vicinity and wants to land: This time will depend on the size of the airport, the number of planes in the queue, and the amount of time it takes for the plane to taxi off the runway.

In a normal distribution, data points are referred to as x, whereas in a z-distribution, they are referred to as z or z scores. A z score is a standard score that indicates how many standard deviations a given number (x) is from the mean:

If your x value is higher than the mean, your z score will be positive.If your z score is negative, it indicates that your x value is below the meanYour x value is the same as the mean if your z score is zero.

Every z score has a corresponding p-value that indicates the likelihood that all values below or above that z score will occur.

Let f(x) be a nonnegative smooth function (smooth means continuously differentiable) over the interval [a, b]. Then, the area of the surface of revolution formed by revolving the graph of y f(x) about the x-axis is given by
S= b∫a πf(x)1√+[f′(x)]^2 dx

Answers

The formula for the surface area of revolution, S, formed by revolving the graph of y = f(x) about the x-axis over the interval [a, b], is given by S = ∫(a to b) 2πf(x) √(1 + [f'(x)]^2) dx.

To calculate the surface area of revolution, we consider the small element of arc length on the graph of y = f(x). The length of this element is given by √(1 + [f'(x)]^2) dx, which is obtained using the Pythagorean theorem in calculus. We can approximate the surface area of revolution by summing up these small lengths over the interval [a, b]. Since the surface area of a revolution is a collection of circular disks, we multiply the length of each element of arc by the circumference of the disk formed by revolving it, which is 2πf(x). Integrating this expression from a to b, we obtain the formula for the surface area of revolution:

S = ∫(a to b) 2πf(x) √(1 + [f'(x)]^2) dx.

This formula takes into account the variation in the slope of the function f(x) as given by f'(x), ensuring an accurate representation of the surface area of revolution. By evaluating this integral, we can determine the precise surface area for the given function f(x) over the interval [a, b].

Consider the polynomials p1(t) = 1 + t , p2(t) = 1 -t , and p3(t) = 2 (for all t). By inspection, write a linear dependence relation among p1, p2, and p3. Then find a basis for Span{ p1 , p2 , p3 }.
I've already concluded that the polynomials are linearly dependent since 1p1 + 1p2 + (-2)p3 = 0. It's the second part that I'd like help with.

Answers

The basis for Span{ p1, p2, p3 } is { p1, p2 } or equivalently { 1+t, 1-t }.

To find a basis for Span{ p1, p2, p3 }, we need to eliminate any redundant vectors. In this case, since we already know that p1, p2, and p3 are linearly dependent, we can remove one of them from the set and still have the same span.One option is to remove p3, since it is a constant polynomial and doesn't add any new information. So we are left with Span{ p1, p2 }.
To check that { p1, p2 } is indeed a basis for this span, we need to show that they are linearly independent (so we don't have any redundancy) and that they span the same subspace as { p1, p2, p3 }.To show that { p1, p2 } is linearly independent, we assume that a(1+t) + b(1-t) = 0 for some scalars a and b, and show that this implies a = b = 0. Expanding the left side gives a + at + b - bt = (a + b) + (a - b)t. Since this polynomial is identically zero, we must have a + b = 0 and a - b = 0. Solving these equations gives a = b = 0, so { p1, p2 } is indeed linearly independent.To show that { p1, p2 } spans the same subspace as { p1, p2, p3 }, we need to show that any linear combination of p1, p2, and p3 can be written as a linear combination of p1 and p2. But since we already know that 1p1 + 1p2 - 2p3 = 0, we can substitute p3 = (1/2)p1 + (1/2)p2 into any linear combination of p1, p2, and p3 to get a linear combination of just p1 and p2. So { p1, p2 } spans the same subspace as { p1, p2, p3 }.

find minimum number of coins that make a given value

Answers

The given coins [1, 2, 5] and the value 11, the minimum number of coins needed is 2.

Here are the steps to find the minimum number of coins:

1. First, we create an array of size equal to the given value, initialized with a very large number. This array will store the minimum number of coins needed to make each value from 0 to the given value.

2. We set the first element of the array to 0, as it doesn't require any coins to make a value of 0.

3. Next, we iterate through all the coins available and for each coin, we iterate through all the values from the coin value to the given value.

4. For each value, we calculate the minimum number of coins needed by taking the minimum of the current minimum and the value obtained by subtracting the coin value from the current value and adding 1 to it.

5. Finally, we return the value stored in the last element of the array, which represents the minimum number of coins needed to make the given value.

Let's consider an example to better understand the process:

Given coins: [1, 2, 5]
Given value: 11

1. Initialize the array with [INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF] (INF represents infinity).

2. Set the first element of the array to 0, so it becomes [0, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF].

3. For the first coin (1), iterate through the array from index 1 to 11.

  - For index 1, the minimum number of coins needed is 0 + 1 = 1.
  - For index 2, the minimum number of coins needed is 0 + 1 = 1.
  - For index 3, the minimum number of coins needed is 0 + 1 = 1.
  - ...
  - For index 11, the minimum number of coins needed is 0 + 1 = 1.

  The array becomes [0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1].

4. For the second coin (2), iterate through the array from index 2 to 11.

  - For index 2, the minimum number of coins needed is 1 (minimum of 1 and 0 + 1 = 1).
  - For index 3, the minimum number of coins needed is 1 (minimum of 1 and 0 + 1 = 1).
  - For index 4, the minimum number of coins needed is 1 (minimum of 1 and 1 + 1 = 2).
  - ...
  - For index 11, the minimum number of coins needed is 1 (minimum of 1 and 1 + 1 = 2).

  The array becomes [0, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2].

5. For the third coin (5), iterate through the array from index 5 to 11.

  - For index 5, the minimum number of coins needed is 2 (minimum of 2 and 0 + 1 = 1).
  - For index 6, the minimum number of coins needed is 2 (minimum of 2 and 1 + 1 = 2).
  - ...
  - For index 11, the minimum number of coins needed is 2 (minimum of 2 and 2 + 1 = 3).

  The array becomes [0, 1, 1, 1, 2, 1, 2, 2, 2, 2, 3, 2].
