Given V=4ti-6tj Find The Integral Of The Magnitude Over The Bounds [-2,2]?

Answers

Answer 1

The integral of the magnitude of a given vector is 0.

What is vector ?

Vector can be defined as the object  in which it has both magnitude and direction.

Given

vector ,  V=4t i-6t j

we have to find the Integral of the magnitude over the bounds [-2,2]

So, Lets integrate the given vector

we get,

-[tex]\int\limits^2_2 { v dt } \, dx[/tex]    =

|v| =   √4t^2 + (-6t)^2

=  √16t^2 + 36t^2

= √52t^2

=  2√13 t

-[tex]\int\limits^2_2 {2\sqrt{13}t } \, dt[/tex]  =   2√13 t^2 / 2

when we integrate t , we get t = t^2 / 2

= √13 t^2  

=√13 (2^2 - (-2)^2 )

=√13 (4 - 4 )

= 0

Hence, The integral of the magnitude of a given vector is 0.

What is function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in 1837 by the German mathematician Peter Dirichlet.

This relationship is commonly symbolized as y = f(x)—which is said “f of x”—and y and x are related such that for every x, there is a unique value of y. That is, f(x) can not have more than one value for the same x. To use the language of set theory, a function relates an element x to an element f(x) in another set.

there are 24 psychiatrists and 30 psychologists attending a certain conference. three of these 54 people are randomly chosen to take part in a panel discussion. what is the probability that at least one psychologist is chosen?

Answers

Answer: There are a few different ways to approach this problem, but one common method is to use the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening. In this case, we want to find the probability of at least one psychologist being chosen, which is the same as 1 minus the probability of no psychologists being chosen.

To find the probability of no psychologists being chosen, we first need to calculate the total number of ways to choose 3 people from a group of 54, which is:

54 choose 3 = 54! / (3! * 51!) = 19,958

Then we need to find the number of ways to choose 3 psychiatrists from a group of 24, which is:

24 choose 3 = 24! / (3! * 21!) = 1,344

Now, we can use these values to calculate the probability of no psychologists being chosen:

P(no psychologists) = (24 choose 3) / (54 choose 3) = 1,344 / 19,958 = 0.067 or 6.7%

Finally, we can use the complement rule to find the probability of at least one psychologist being chosen:

P(at least one psychologist) = 1 - P(no psychologists) = 1 - 0.067 = 0.93 or 93%

So the probability that at least one psychologist is chosen from the conference is 93%

For this polynomial function, state the coordinate points of the zeros

Answers

The zeros of this polynomial are (1, 0), (2, 0), and (0, 4).

How determine the zeros of the polynomial?

The zeros of the polynomial can be determined by setting the equation equal to zero and solving for the roots.

For example, if the polynomial is given as [tex]ax^{2}[/tex] + bx + c, then the zeros can be determined by solving the equation [tex]ax^{2}[/tex] + bx + c=0.

Step 1: To determine the zeros of the polynomial, set the polynomial equal to 0 and solve for x.

f(x) = [tex]x^{3}[/tex] - [tex]3x^{2}[/tex] + 4 = 0

Step 2: Factor the polynomial to solve for x.

[tex]x^{3}[/tex] - [tex]3x^{2}[/tex] + 4 = 0

x([tex]x^{2}[/tex] - 3x + 4) = 0

Step 3: Factor the quadratic equation.

x(x - 1)(x - 2) = 0

Step 4: Set each factor equal to 0 and solve for x.

x = 0, x = 1, x = 2

Step 5: Plug each x-value into the original equation to determine the corresponding y-value for each zero.

When x = 0, y = 4

When x = 1, y = 0

When x = 2, y = 0

Answers

The decrease in Kaitlin's investment account is 7%, which is calculated by multiplying the initial $5200 by 0.07.

This gives a decrease of $364. The amount in her account at the end of the year is the initial $5200 minus the decrease of $364, which equals $4836.

Solve the system of equations x+3y=5 and -3x-2y=20 by combining the equations

Answers

The value of x and y is -10 and 5 respectively in the given equations.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The first linear equation is - x + 3y = 5

The second linear equation is - -3x - 2y = 20

On evaluating individually the equation obtained is -

-3x - 2y + x + 3y = 20 + 5

-2x + y = 25

Multiply equation (1) with 3 -

3(x + 3y) = 5 × 3

3x + 9y = 15.....(3)

Adding equation (3) and (2) -

-3x - 2y + (3x + 9y) = 20 + 15

-3x - 2y + 3x + 9y = 35

-2y + 9y = 35

7y = 35

y = 35/7

y = 5

Substituting the value of y in equation (1) -

x + 3y = 5

x + 3(5) = 5

x + 15 = 5

x = 5 - 15

x = -10

Therefore, the value of x and y is -10 and 5 respectively.

2FePO4 + 3Na2SO4 Right arrow. Fe2(SO4)3 + 2Na3PO4


What is the theoretical yield of Fe2(SO4)3 if 20.00 g of FePO4 reacts with an excess of Na2SO4?

Answers

The theoretical yield of Fe₂(SO₄)³ if 20.00 g of FePO₄ reacts with an excess of Na₂SO₄ is 26.52g.

What is a theoretical yield?

The amount of a product produced by a reaction is expressed in terms of the reaction's yield.

Given the chemical equation:

2FePO₄ + 3Na₂SO₄ → Fe₂(SO₄)₃ + 2Na₃PO₄

Theoretical molar ratios:

2 mol FePO₄  : 3 mol Na₂SO₄ : 1 mol Fe₂(SO₄)₃ : 2 mol Na₃PO₄

Convert 20.00 g of FePO₄  into a number of moles

number of moles = mass in grams / molar mass

molar mass of FePO₄  = 150.82 g/mol

Number of moles = 20.00 g / 150.82 g/mol = 0.1326 mol FePO₄

Proportionality

1 mol Fe₂(SO₄)₃                x

----------------------- =  ------------------------

2 mol FePO₄            0.1326 mol FePO₄

Solve for x:

x = (0.1326 / 2) x 1 mol Fe₂(SO₄)₃ = 0.0663 mol Fe₂(SO₄)₃

Convert 0.0663 mol Fe₂(SO₄)₃ into grams

mass in grams = number of moles x molar mass

molar mass Fe₂(SO₄)₃ = 399.88 g/mol

mass = 0.0663 mol x 399.88 g/mol = 26.51 g

Depending on the number of decimal digits used by one or other you might obtain 26.52 instead 26.51, that difference does not count.

Therefore, the theoretical yield of Fe₂(SO₄)³ is 26.52g.

1) The end behavior of a rational function is equal to

A) Holes

B) Horizontal Asymptote

C) Vertical Asymptote

D) Domain

Answers

Answer:

B) Horizontal Asymptote

A horizontal asymptote is a horizontal line that the graph of a function approaches as the input values get larger or smaller. The end behavior of a rational function is determined by the degree of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, the function will approach a horizontal asymptote as the x-values get larger or smaller. If the degree of the numerator is greater than the degree of the denominator, the function will not have a horizontal asymptote.

Answers

The proportion of the individuals that spend more than $400 is 0.35 and  the percent of calls answered in less than 5 minutes is 5.3%

How to determine the probabilities

Probability 1

From the question, we have the following parameters that can be used in our computation:

Mean = 384

Standard deviation = 48

x = 400

The z-score is calculated as

z = (x - Mean)/Standard deviation

So, we have

z = (400 - 384)/40

z = 0.4

The required probability is

P = P(z > 0.4)

So, we have

P = 0.345

Probability 2

Here, we have

Mean = 12.4

Standard deviation = 4.3

x = 5

The z-score is calculated as

z = (x - Mean)/Standard deviation

So, we have

z = (12.4 - 4.3)/5

z = 1.62

The required probability is

P = P(z > 1.62)

So, we have

P = 5.3%
