If a car is moving on a straight line with a velocity of 40 m/s and it changes its velocity to 60 m/s in 4 seconds, calculate its acceleration.

Answers

Answer:

5m/s²

Step-by-step explanation:

Given :-

Initial Velocity = 40m/s Final velocity = 60 m/sTime = 4s

To Find :-

The acceleration .

Solution :-

We know that the rate of change of velocity is called acceleration. Therefore ,

\(\sf\implies a = v - u / t \\ \)

\(\sf\implies a = 60m/s - 40m/s/ 4 \\ \)

\(\sf\implies a = 20m/s \div 4 \\\)

what is the volume of the parallelepiped with sides i, 3j − k, and 6i 2j − k?

Answers

The absolute value of the determinant of the matrix formed by the given sides is 3, which represents the volume of the paralleled pipe.

What is the volume of the given paralleled pipe?

To find the volume of a parallelepiped with three sides given as vectors, we take the triple scalar product (also known as the box product) of the vectors.

Let's first find the three vectors given in the problem statement:

First vector, a = iSecond vector, b = 3j − kThird vector, c = 6i + 2j − k

Now we take the triple scalar product:

a · (b x c) = a · d

where d = b x c is the cross product of b and c.

b x c = det([[j,k], [3, -1]])i - det([[i,k], [6,-1]])j + det([[i,3], [6,2]])k

= (-3i - 7j - 18k)

So, d = b x c = -3i - 7j - 18k

Now,

a · d = (1)(-3) + (0)(-7) + (0)(-18) = -3

Thus, the volume of the parallelepiped is |-3| = 3 cubic units.

Andre, Lin, and Noah each designed and built a paper airplane. They launched each plane several times and recorded the distance of each flight in yards. Write the five-number summary for the data for each airplane. Then, calculate the interquartile range for each data set.

Andre, Lin, and Noah each designed and built a paper airplane. They launched each plane several times

Answers

Let's say the distances recorded for each airplane are:

Andre's: 18, 20, 22, 25, 28, 29, 30, 31, 32, 35
Lin's: 15, 16, 18, 20, 21, 22, 23, 25, 30, 33
Noah's: 10, 12, 13, 15, 18, 20, 21, 22, 23, 25

To find the five-number summary for each data set, we need to find the minimum, maximum, median, and quartiles. We can start by ordering the data sets from smallest to largest:

Andre's: 18, 20, 22, 25, 28, 29, 30, 31, 32, 35
Lin's: 15, 16, 18, 20, 21, 22, 23, 25, 30, 33
Noah's: 10, 12, 13, 15, 18, 20, 21, 22, 23, 25

Minimum:
Andre's: 18
Lin's: 15
Noah's: 10

Maximum:
Andre's: 35
Lin's: 33
Noah's: 25

Median:
Andre's: (28 + 29) / 2 = 28.5
Lin's: (21 + 22) / 2 = 21.5
Noah's: (18 + 20) / 2 = 19

First Quartile (Q1):
Andre's: (22 + 25) / 2 = 23.5
Lin's: (18 + 20) / 2 = 19
Noah's: (12 + 13) / 2 = 12.5

Third Quartile (Q3):
Andre's: (31 + 32) / 2 = 31.5
Lin's: (23 + 25) / 2 = 24
Noah's: (22 + 23) / 2 = 22.5

Interquartile Range (IQR):
IQR = Q3 - Q1
Andre's: 31.5 - 23.5 = 8
Lin's: 24 - 19 = 5
Noah's: 22.5 - 12.5 = 10

So the five-number summary and interquartile range for each data set are:

Andre's: Min = 18, Q1 = 23.5, Median = 28.5, Q3 = 31.5, Max = 35, IQR = 8
Lin's: Min = 15, Q1 = 19, Median = 21.5, Q3 = 24, Max = 33, IQR = 5
Noah's: Min = 10, Q1 = 12.5, Median = 19, Q3 = 22.5, Max = 25, IQR = 10

Answer:

Andre's: Min = 18, Q1 = 23.5, Median = 28.5, Q3 = 31.5, Max = 35, IQR = 8

Lin's: Min = 15, Q1 = 19, Median = 21.5, Q3 = 24, Max = 33, IQR = 5

Noah's: Min = 10, Q1 = 12.5, Median = 19, Q3 = 22.5, Max = 25, IQR = 10

Answers

Answer:

x = 8, y = -7

Step-by-step explanation:

first, find x using the second equation:

x - 9 = -1

add 9 to both sides of the equation

x - 9 + 9 = - 1 + 9

x = -1 + 9

x = 8

next, substitute x for 8 in the first equation:

2x - y = 23

2 * 8 - y = 23

16 - y = 23

16 - y + y = 23 + y

16 = 23 + y

16 - 23 = y

y = -7

intermediate models of integration are different from the enemies and allies models because

Answers

Intermediate models of integration differ from the enemies and allies models due to their approach in fostering collaboration and cooperation between different entities while maintaining a certain degree of autonomy and independence.

Intermediate models of integration, in contrast to enemies and allies models, aim to establish a framework where entities can work together while retaining their individual identities and interests. These models recognize that complete integration or isolation may not be the most optimal or feasible approaches. Instead, they emphasize the importance of collaboration and cooperation between different entities, such as organizations or countries, while respecting their autonomy.

In intermediate models of integration, entities seek to identify shared goals and interests, leading to mutually beneficial outcomes. They acknowledge the value of diversity and differences in perspectives, considering them as assets rather than obstacles. This approach encourages open communication, negotiation, and compromise to bridge gaps and find common ground. Rather than viewing other entities as adversaries or allies, the emphasis is on building relationships based on trust, transparency, and shared values.

Intermediate models of integration often involve the establishment of frameworks, agreements, or platforms that facilitate collaboration while allowing for flexibility and adaptation to changing circumstances. These models promote inclusivity, recognizing that integration can be a complex process that requires active participation from all involved entities. By combining the strengths and resources of different entities, intermediate models of integration strive to achieve collective progress and shared prosperity while acknowledging the importance of maintaining individual identities and interests.

Arrange from shortest to longest time:
3.44 ns
7.48 x 10^2 ps
1.55 x 10^-3 ms

Answers

To arrange the given times from shortest to longest, let's convert all the times to a common unit for easier comparison. Let's convert all the times to seconds (s). The correct arrangement from shortest to longest time is: 7.48 x \(10^{-4}\)µs, 3.44 x \(10^{-3}\) µs, 1.55 µs

1 ns = 10^-9 s (nanoseconds to seconds)

1 ps = 10^-12 s (picoseconds to seconds)

1 ms = 10^-3 s (milliseconds to seconds)

3.44 ns = 3.44 x 10^-9 s

7.48 x 10^2 ps = 7.48 x 10^-10 s

1.55 x 10^-3 ms = 1.55 x 10^-6 s

Arranging the times from shortest to longest:

7.48 x 10^-10 s (ps)

3.44 x 10^-9 s (ns)

1.55 x 10^-6 s (ms)

Therefore, the arranged times from shortest to longest are:

7.48 x 10^-10 s (ps) < 3.44 x 10^-9 s (ns) < 1.55 x 10^-6 s (ms)

the cross section of a prism is a triangle having base angles each 60 degree . if the height of prism is 6√3 cm and volume 162cm^3 , find the side of the cross - section.

Answers

Answer:

6

Step-by-step explanation:

volume of prism = area of cross section * height

area of cross section =162/6√3 =27/√3

since the base angles are each 60 degrees, the triangle is an equilateral triangle. for equilateral triangles, area =(√3 * side^2)/4

hence,

27/√3 = (√3 * side^2)/4

side^2 = (27/√3) / (√3/4) = 108/3 = 36

square $aime$ has sides of length 10 units. isosceles triangle $gem$ has base $\overline{em}$, and the area common to triangle $gem$ and square $aime$ is 80 square units. find the length of the altitude to $\overline{em}$ in triangle $gem$.

Answers

The length of the altitude to line segment $\overline{em}$ in triangle $gem$ is 16 units.

Let's denote the length of the altitude to line segment $\overline{em}$ in triangle $gem$ as $h$.

The area of a triangle is given by the formula:

Area = (base * height) / 2

The area common to triangle $gem$ and square $aime$ is 80 square units. Since the base of triangle $gem$ is $\overline{em}$, we have:

80 = (10 * h) / 2

160 = 10h

Solving for $h$, we have:

h = 160 / 10

h = 16

What are the tax consequences to Euclid from the following independent events? In your computations, do not round intermediate division. If required, round the per share answer to two decimal places. Round all other answers to the nearest dollar. a. Euclid bought 500 shares of common stock five years ago for $50,000. This year, Euclid receives 20 shares of common stock as a nontaxable stock dividend. As a result of the stock dividend, Euclid's per share basis is $ X. b. Assume instead that Euclid received a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000. After the receipt of the stock dividend, the basis of the preferred stock is $ X, and the basis of the common stock is Φ

Answers

Euclid receives 20 shares of common stock as a nontaxable stock dividend.The basis of the common stock remains the same as in scenario a, which is $96.15 per share.

To calculate the per share basis, we divide the original purchase cost by the total number of shares (including the dividend shares).  In scenario b, Euclid receives a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000.

The tax consequences involve determining the new basis of the preferred stock and the common stock after the dividend. a. To find the per share basis of Euclid's common stock after receiving the stock dividend, we divide the original purchase cost by the total number of shares. The original purchase cost was $50,000 for 500 shares, which means the per share basis was $50,000/500 = $100. After receiving 20 additional shares as a dividend, the total number of shares becomes 500 + 20 = 520.

Therefore, the new per share basis is $50,000/520 = $96.15. b. In this scenario, Euclid receives a preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock has a fair market value of $75,000. To determine the new basis of the preferred stock, we consider its fair market value.

Since the preferred stock dividend is nontaxable, its basis is equal to the fair market value, which is $5,000.
