How to determine the slopes

The slope is represented as m, The slope by definition is the ratio change of the output values to the input values

The slope, m using the points A(-2, 4), and B(-1, 1)

m = (y₀ - y₁) / (x₀ - x₁)

m = (4 - 1) / (-2 - -1)

m = (3) / (-1)

m = -3

The slope, m using the points B(-1, 1), and C(2, 2)

m = (1 - 2) / (-1 - 2)

m = (-1) / (-3)

m = 1/3

The slope, m using the points A(-2, 4), and C(2, 2)

m = (4 - 2) / (-2 - 2)

m = (2) / (-4)

What is function ?

A function is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs. A mapping from A to B will only be a function if every element in set A has one end and only one image in set B. Let A & B be any two non-empty sets.

a = t, b = -t and c = 2t

So, the magnitude of r(t) =  √(a² + b² + c²)

Suppose a 3 X 3 real matrix A has only two (real) distinct eigenvalues. Suppose that tr(A) -2 and det(A) 96. Find the eigenvalues of with their algebraic multiplicities. smaller eigenvalue has mulitiplicity and larger eigenvalue has mulitiplicity

Answers

The smaller eigenvalue is -4 with multiplicity 2 and larger eigenvalue is 6 has multiplicity 1

If A is a square matrix of order n x n and v is a non-zero column vector of order n x 1 such that Av = λv , then the scalar (real number) λ is called an eigenvalue of the matrix A that corresponds to the eigenvector v.

According to the question,

We have a 3 x 3 matrix that has only two real distinct eigenvalues

Let two distinct eigen values be a and b

Its given that tr(A) = - 2

Det(A) = 96

If we add all the eigen values of a matrix it gives us trace of this and product of eigen values result to the determinant

Therefore , 2a + b = -2 --------(1)

a²b = 96 --------(2)

Using substitution method for solving these equations

=> b = -2 - 2a

Substituting the value of b in equation (2)

=> a²( -2 -2a) = 96

=> -2a² - 2a³ = 96

=> a²(1 + a) + 48 = 0

=> a³ + a² + 48 =0

Solving the cubic equation

a = -4 , 1.5-3i , 1.5+3i (but eigen values are only real)

therefore , a = -4

b = -2 -2(-4)

=> -2+8

=> 6

hence, the eigen values = -4 and 6

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

What is an expression?

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

Calculation:

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

A coefficient is a number that is placed in front of a variable. A variable and a rational number are preceded by a rational coefficient, which may be an integer, decimal, or fraction.

(x - (-4))(x-8) = (x+4)(x-8) = x² - 8x + 4x - 32 = x² - 4x - 32

1x² - 4x - 32 is a polynomial function of least degree with rational coefficients that satisfices the given conditions. The leading coefficient here is 1, we call this a monic polynomial.

2. There may be something missing in the question here

3. We can use the factoring techniques to find the roots :

x^3 - 5x² + 9x - 45 let us group x^3 with -5x² and 9x with -45 :

(x^3 - 5x²) + (9x - 45) = x²(x - 5) + 9(x - 5)

We can notice now that there is a common factor : (x-5) this allows us to factor again by (x-5) :

Y = (x-5)(x²+9)

This is the maximum we can do on R, but on C the set of complex we can still factor again.

x² + 9 has a negative discriminant : Δ = b² - 4ac where b = 0 , a = 1, c = 9

Δ < 0, Δ = - 36

Applying the formulas for the roots x1 and x2 we get x1 = -3i, and x2 = + 3i

Y = (x-5)(x-3i)(x+3i)

So the solution is S = {5, 3i, -3i} the three roots of the function.

What is causality in linear regression?

Causality means that there is a clear cause-effect relationship between two variables. By using a controlled study is the most effective way of establishing causality among variables. In a controlled study, the sample or population is split in two, with both groups being comparable in almost every way. Then, the two groups receive different treatments, and the outcomes of each group are assessed.

Say that a woman and a man (who are unrelated) each has two children. We know that at least one of the woman's children is a boy and that the man's oldest child is a boy. Can you explain why the chances that the woman has two boys do not equal the chances that the man has two boys?My algebra teacher insists that the probability is greater that the man has two boys, but I think the chances may be the same. What do you think?

Answers

Therefore, the probability that a woman will give birth to two boys is only one in three, whereas the probability that a man will do so is one in two.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here,

The woman may have at least one boy in the three following ways: 1) older boy, younger girl; 2) older girl younger boy; 3) older boy, younger boy.

But the man's children may be distributed in only two ways: 1) older boy, younger girl; or 2) older boy, younger boy.

So the chances are only 1 out of 3 that the woman has two boys, but the chances are 1 out of 2 that the man has two boys.

8 a What percentage of $680 is $490 ?
b A price is reduced from $680 to $490. What is the percentage decrease?

Answers

a) The percentage of $680 which is $490 is 72.06%.

b) When a price is reduced from $680 to $490, the percentage decrease is 27.94%.

What is the percentage?

The percentage is the ratio of a value to another.

Percentages are depicted as fractional values expressed over 100.

To determine percentages, the smaller value is expressed as the numerator, while the more considerable value is described as the denominator.

The result is then multiplied by 100.

For instance:

$490 of $680 is 72.06% ($490/$680 x 100)

Price reduction from $680 to $490, the percentage decrease is computed as the difference between $680 and $490 divided by $680, multiplied by 100.

Thus, the percentage decrease in price from $680 to $490 is 27.94%, showing that the original price of the good or service has been reduced from 100% to 72.06%.

Answers

If ∠2=10x+7 and one angle is 67 degrees then value of x is 6.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given that the triangle has two equal sides which makes the triangle as isosceles.

In an isosceles triangle the two sides will be always equal and the angles will be also equal.

One angle of the triangle is 67 degrees

We need to find the ∠2.

As we know that the equal sides make equal angles.

∠2=67 degrees

and from given ∠2=10x+7

Now equation 67 with the 10x+7 to find the value of x.

So 67=10x+7

subtract 7 from both sides

67-7=10x+7-7

60=10x

Divide both sides by 10

x=60/10

x=6

Hence, the value of x is 6.
