Displament is defined as the what and what of an objects change in position from the starting point

Answers

Displacement is defined as the magnitude and direction of an object's change in position from the starting point.What is displacement?Displacement refers to the overall change in the position of an object over a specified period of time. It takes both magnitude and direction into account.

Displacement, as opposed to distance traveled, is a vector amount that considers not only the total distance traveled but also the direction in which the object moved.

Displacement is the length of the straight line connecting the beginning and ending positions of an object, as well as the direction of this line.

There are a few key things to keep in mind about displacement:Displacement is calculated using the formula: Displacement (Δd) = Final Position - Initial Position (d₂ - d₁)

Displacement is a vector amount since it includes both magnitude and direction.

If an object moves around in a circle and finishes where it began, its displacement will be zero but the distance it travels will not.

In the coordinate plane, what is the length of the line segment that connects points at (4, - 1) and (9, 7)? Enter your answer in the box. Round to the nearest hundredth.

Answers

The length of the line segment that connects the points (4, -1) and (9, 7) is approximately 9.43 units.

What is the length of the line segment?

The distance formula used in finding the distance between two points is expressed as;

[tex]d = \sqrt{(x_2 - x_1)^2+( y_2 - y_1)^2}[/tex]

Given that; the coordinates are (4, -1) and (9, 7), so we have:

x₁ = 4

y₁ = -1

x₂ = 9

y₂ = 7

Substituting these values into the distance formula, we get:

[tex]d = \sqrt{(x_2 - x_1)^2+( y_2 - y_1)^2}\\\\d = \sqrt{(9 - 4)^2+( 7 - (-1))^2}\\\\d = \sqrt{(5)^2+( 7 + 1)^2}\\\\d = \sqrt{(5)^2+( 8)^2}\\\\d = \sqrt{ 25 + 64}\\\\d = \sqrt{ 89}\\\\d = 9.43[/tex]

Answers

The false statement is option d. summary(patient History) can be used if you precede it by entering attach(patientHistory$summary)

a. patient History$age will print all the elements of the age column.

This statement is true.

If you want to print all the elements of the age column in a data frame called patient History, you can use the dollar sign ($) operator to access the column by name.

So patient History$age will give you a vector containing all the age values.

b. gender <("M", "F", NA) is a valid column vector.

This statement is false.

The syntax of this statement is not correct. If you want to create a valid column vector with the values "M", "F", and NA, you can use the c() function like this: gender <- c("M", "F", NA). The c() function is used to combine values into a vector.

c. Using the attach() function can reduce the number of characters needed to create an R script. This statement is true, but it's important to be aware of the potential risks of using attach().

The attach() function can make it easier to access columns in a data frame without having to specify the data frame name every time.

However, it can also create confusion and errors if there are multiple objects with the same name in different environments. It's generally recommended to avoid using attach() and instead use the $ operator or the with() function.

d. summary(patient History) can be used if you precede it by entering attach(patientHistory).

This statement is false. The correct syntax to use the summary() function on a data frame is summary(patient History), without the attach() function.

The summary() function provides a summary of the statistics for each column in the data frame.

So, the false statement is option d. I hope this helps! Let me know if you have any further questions.

determine the general solution of x′ = (−1 1 −1 −1 ) x

Answers

The general solution of the given system is x(t) = c1t(1 1) + c2t(1 -1).

To find the general solution of x′ = (−1 1 −1 −1 ) x, we first need to find the eigenvalues and eigenvectors of the matrix A = (−1 1 −1 −1).

The characteristic polynomial of A is given by det(A - λI) = 0, where I is the 2x2 identity matrix and λ is the eigenvalue:

|−1-λ 1 |

|-1 -λ| = (-1-λ)(-1-λ) - (-1)(1) = λ^2 + 2λ = λ(λ+2) = 0.

So the eigenvalues of A are λ1 = 0 and λ2 = -2.

To find the eigenvectors corresponding to each eigenvalue, we need to solve the equations:

(A - λ1I)x1 = 0 and (A - λ2I)x2 = 0.

For λ1 = 0, we have:

(A - λ1I)x1 =

| -1 1 |

| -1 -1 | x1 = 0.

Solving this system of equations, we get x1 = t(1 1), where t is any scalar.

For λ2 = -2, we have:

(A - λ2I)x2 =

| 1 1 |

| -1 -3 | x2 = 0.

Solving this system of equations, we get x2 = t(1 -1), where t is any scalar.

Thus, the general solution of x′ = (−1 1 −1 −1 ) x can be written as a linear combination of the eigenvectors:

x(t) = c1t(1 1) + c2t(1 -1),

Let P(A∩B)= 0.3 and P(A∩B^c)= 0.15 and and P(A^c∩B)=0.35P. Compute P(A^c∩B^c)

Answers

The value of probability is P(A^c∩B^c) = 0.2.

Using the formula P(A) = P(A ∩ B) + P(A ∩ B^c) and P(A^c) = 1 - P(A), we can compute P(A) and P(B) as follows:

P(A) = P(A ∩ B) + P(A ∩ B^c) = 0.3 + 0.15 = 0.45

P(A^c) = 1 - P(A) = 1 - 0.45 = 0.55

Similarly, we can compute P(B) using P(B ∩ A) + P(B ∩ A^c) = P(B ∩ A) + P(A^c ∩ B) = 0.35P, which gives P(B) = 0.35P.

Using the formula P(A ∪ B) = P(A) + P(B) - P(A ∩ B), we can compute P(A ∪ B) as follows:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = 0.45 + 0.35P - 0.3 = 0.15 + 0.35P

Since P(A ∪ B) + P(A^c ∪ B^c) = 1, we have

P(A^c ∪ B^c) = 1 - P(A ∪ B) = 1 - (0.15 + 0.35P) = 0.85 - 0.35P

Finally, using the formula P(A^c ∩ B^c) = 1 - P(A ∪ B) = 1 - (0.15 + 0.35P) = 0.85 - 0.35P. Therefore, P(A^c ∩ B^c) = 0.85 - 0.35P.

find the radius of convergence, r, of the series. [infinity] (−1)n xn 3n ln(n) n = 2

Answers

Answer: The radius of convergence of the series Σ(-1)ⁿ xⁿ 3ⁿ ln(n) with n=2 is 3.

To find the radius of convergence of the series Σ(-1)ⁿ xⁿ 3ⁿ ln(n) from n=2 to infinity, we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges absolutely, and the radius of convergence r is the reciprocal of the limit. If the limit is greater than 1, then the series diverges, and if the limit is equal to 1, the test is inconclusive.

So, applying the ratio test to our series, we have:

|(-1)(ⁿ+¹+¹) x(ⁿ+¹) 3(ⁿ+¹) ln(n+1)| / |(-1)ⁿ xⁿ 3ⁿ ln(n)|

= |x|/3 * ln(ⁿ+¹)/ln(n)

As n approaches infinity, the limit of this expression is:

lim n->inf |x|/3 * ln(n+1)/ln(n) = |x|/3 * 1 = |x|/3

So the series converges absolutely if |x|/3 < 1, or equivalently, if |x| < 3. Therefore, the radius of convergence is r = 3.

A rectangle with a width of 0. 75 miles and height of 0. 5 miles. The 2 mile finish comes out of one corner. Using the equation w (1. 5 1) 2 = 17, the race’s organizer determined the cyclists will need to ride 9 laps before the sprint to the finish. Which explains the error? The equation should be 0. 75 w 0. 5 w 2 = 17, and the cyclists will need to ride 12 laps before the sprint to the finish. The equation should be 2 (0. 75 w 0. 5) 2 = 17, and the cyclists will need to ride 21 laps before the sprint to the finish. The solution should be 6, and the cyclists will need to ride 6 laps before the sprint to the finish. The solution should be 8, and the cyclists will need to ride 8 laps before the sprint to the finish.

Answers

The correct equation is 0.75w + 0.5w + 2 = 17.

To determine the error in the given equation and find the correct number of laps needed before the sprint to the finish, we can follow these steps:

Step 1: Examine the given equation, w(1.5 + 1)^2 = 17, and identify the error.

The equation provided is incorrect because it does not account for the width and height of the rectangle, as well as the 2-mile sprint to the finish line.

Step 2: Formulate the correct equation based on the given information.

The correct equation should be 0.75w + 0.5w + 2 = 17, where w represents the number of laps. This equation includes the distance covered by riding laps around the block (0.75w + 0.5w) and the additional 2-mile sprint to the finish line.

Step 3: Solve the equation to find the correct number of laps.

By simplifying the equation, we get 1.25w + 2 = 17. Subtracting 2 from both sides gives us 1.25w = 15. Dividing both sides by 1.25 yields w = 12.

Therefore, the correct equation is 0.75w + 0.5w + 2 = 17, and the cyclists will need to ride 12 laps before the sprint to the finish. The given equation and the incorrect number of laps mentioned in the other options do not accurately represent the race distance and the laps required.

find the particular solution that satisfies the differential equation and the initial condition. f ''(x) = 6, f '(2) = 14, f(2) = 19

Answers

The particular solution that satisfies the differential equation f''(x) = 6, f'(2) = 14, f(2) = 19 is f(x) = 3x² + 2x + 3.

To find the particular solution that satisfies the given differential equation and initial conditions, we need to integrate the differential equation twice and use the initial conditions to solve for the constants of integration.

The given differential equation is

f''(x) = 6

First, integrating the differential equation once gives us

f'(x) = 6x + C₁

where C₁ is a constant of integration.

Next, integrating again with respect to x, we get

f(x) = 3x²  + C₁x + C₂

where C₂ is another constant of integration.

To find the values of C₁ and C₂, we can use the initial conditions

f '(2) = 14,

f(2) = 19

f'(2) = 6(2) + C₁ = 14

C₁ = 2

From the second initial condition, we have

f(2) = 3(2)²  + C₁(2) + C₂ = 3(2)²  + 2(2) + C₂ = 19

C₂ = 3

The missing coordinate of point P is sqrt(5/9). The complete coordinates of P in quadrant II are (-2/3, sqrt(5/9)).

To find the missing coordinate of p, we need to use the fact that p lies on the unit circle in the given quadrant. The coordinates of a point on the unit circle are (cosθ, sinθ), where θ is the angle that the point makes with the positive x-axis.
In this case, we know that p lies in quadrant ii, which means that its x-coordinate is negative and its y-coordinate is positive. We also know that the length of the vector OP, where O is the origin and P is the point on the unit circle, is 1.
Using the Pythagorean theorem, we can write:
(OP)^2 = x^2 + y^2 = 1
Substituting the given coordinates of p, we get:
(-2)^2 + 3^2 = 1
4 + 9 = 1
This is clearly not true, so there must be an error in the given coordinates of p.
Therefore, we cannot find the missing coordinate of p using the given information.

b.-25 c.-27 d.-23

Answers

The arithmetic sequence are solved and the missing terms are

a) -3.5, -8, -12.5, -17

b) 1, 5, 17, 53, 161

c) 15th term is a15 = -25

Given data ,

The nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

a)

The common difference is d = (a5 - a1)/(5-1) = (-17 - 1)/4 = -4.5, so the missing terms are

a2 = a1 + d = 1 - 4.5 = -3.5

a3 = a2 + d = -3.5 - 4.5 = -8

a4 = a3 + d = -8 - 4.5 = -12.5

Therefore, the answer is (d) -3.5, -8, -12.5, -17

b)

a2 = 3a1 + 2 = 3(1) + 2 = 5

a3 = 3a2 + 2 = 3(5) + 2 = 17

a4 = 3a3 + 2 = 3(17) + 2 = 53

a5 = 3a4 + 2 = 3(53) + 2 = 161

Therefore, the answer is (c) 1, 5, 17, 53, 161

c)

The common difference is d = a6 - a3 = -11 - (-5) = -6, so we get

a4 = a3 + d = -5 - 6 = -11

a5 = a4 + d = -11 - 6 = -17

a6 = a5 + d = -17 - 6 = -23

a7 = a6 + d = -23 - 6 = -29

a8 = a7 + d = -29 - 6 = -35

Therefore, the 15th term is a15 = a14 + d = a6 + 8d = -11 + 8(-6) = -53

Therefore, the answer is (b) -25

Hence , the arithmetic progression is solved

Write an equation of the graph shown in terms of cosine:

Answers

Answer:

Step-by-step explanation:

A squiggly line can refer to a variety of different shapes or patterns. To create an equation using cosine that resembles a squiggly line, you can use a combination of sine and cosine functions with different frequencies and amplitudes. Here's an example equation that produces a squiggly pattern:

y = A * cos(B * x) + C * sin(D * x)

In this equation, A, B, C, and D are constants that you can adjust to modify the shape and characteristics of the squiggly line. By experimenting with different values for these constants, you can create various squiggly patterns. Keep in mind that the specific equation may vary depending on the exact shape and features you have in mind for the squiggly line.

The results of a company’s study shows that it sells its product to 58% ofall people who make telephone enquiries to them.(i) What is the percentage of enquiries where no sale is made?(ii) If in a month 2800 enquiries are made, how many sales would the company expect to make?

Answers

i) The percentage of enquires where no sale is made is 42%.

ii) If in a month 2,800 inquiries are made, the company would expect to make sales of 1,624.

What is the percentage?

The percentage refers to the quotient of a number or value multiplied by 100.

The quotient is the result of a division operation that compares a portion of a quantity with the whole.

The percentage of people who make telephone enquires and buy the company's products = 58%

i) The percentage of the people who make telephone inquiries but do not buy the company's products = 42% (100% - 58%)

ii) The number of inquiries made in a month = 2,800

The expected number of sales for the month = 1,624 (2,800 x 58%)

Thus, based on the percentage of expected sales, when 2,800 inquiries are made, the company should make 1,624 sales.

let f : r3 -- r2 satisfy the conditions /(0) = (1, 2) and [ 1 2 3 ] d/(0) = . 0 0 1 let g : r2 -- r2 be defined by the equation g(x, y) = (x 2y 1, 3xy) . find d(g o /)(0).

Answers

df(0) = [0 0 0; 0 0 0]

d(g o f)(0) = [0 0; 0 0].

We have f: R^3 → R^2 and g: R^2 → R^2.

Using the chain rule, we have:

d(g o f)(0) = dg(f(0)) ◦ df(0)

First, let's find df(0):

df(0) = [∂f₁/∂x₁(0) ∂f₁/∂x₂(0) ∂f₁/∂x₃(0); ∂f₂/∂x₁(0) ∂f₂/∂x₂(0) ∂f₂/∂x₃(0)]

We know that f(0) = (0, 0, 0) and f(0) = (1, 2), so:

f₁(0) = 1, f₂(0) = 2

∂f₁/∂x₁(0) = ∂f₁/∂x₂(0) = ∂f₁/∂x₃(0) = 0

∂f₂/∂x₁(0) = ∂f₂/∂x₂(0) = ∂f₂/∂x₃(0) = 0

Next, let's find dg(f(0)):

dg(x, y) = [∂g₁/∂x ∂g₁/∂y; ∂g₂/∂x ∂g₂/∂y]

dg(1, 2) = [2 1; 6 3]

Finally, we can find d(g o f)(0):

d(g o f)(0) = dg(f(0)) ◦ df(0) = [2 1; 6 3] ◦ [0 0 0; 0 0 0] = [0 0; 0 0]

The derivative of the composition g o f at (0) given by applying the chain rule is [2 4; 3 1].

The problem requires finding the derivative of the composition g o f at (0).

Using the chain rule, we can express this derivative as the product of the Jacobian matrix of g with respect to its inputs and the Jacobian matrix of f with respect to its inputs, evaluated at (0).

The Jacobian matrix of g is given by:

[ 2y 1 2x ]

[ 3y 3x ]

If T : Rn → R

m is a linear transformation, then T(0) = 0.

Evaluating this at f(0) = (1, 2) gives:

[ 4 2 ]

[ 6 3 ]

The Jacobian matrix of f is given by:

[ 1 0 0 ]

[ 0 1 0 ]

Evaluating this at 0 gives:

[ 1 0 0 ]

[ 0 1 0 ]

Multiplying these two matrices, we get:

[ 2 4 ]

[ 3 1 ]

Therefore, d(g o /)(0) = [2 4; 3 1].

In summary, we used the chain rule to find the derivative of the composition g o f at (0), which is given by the product of the Jacobian matrix of g and the Jacobian matrix of f, both evaluated at the same point.
