x is an obtuse angle and sin x = 0.43.
Find the value of x.

Answer:

  A. x ≠ -4 or +4

  B. no solution

Step-by-step explanation:

You want the restrictions on x and the solution to the equation ...

  3/(x+4) +2/(x-4) = 16/((x +4)(x -4))

The denominator factors are (x+4) and (x-4). The values of x that make these zero are -4 and +4, respectively.

The variable may not have values -4 or +4.

In order to avoid extraneous solutions, it often works well to rewrite the equation in the form f(x) = 0. We can subtract 16/((x+4)(x-4)) from both sides to make that happen.

  [tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}-\dfrac{16}{(x+4)(x-4)}=0\\\\\\\dfrac{3(x-4)+2(x+4)-16}{(x+4)(x-4)}=0\\\\\\\dfrac{5x-20}{(x+4)(x-4)}=\dfrac{5(x-4)}{(x+4)(x-4)}=\dfrac{5}{x+4}=0[/tex]

There is no value of x that will make this true. The equation has no solution.

Any complex number can be divided into four categories based on the characteristics of the real component and imaginary part:

Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota." I has the value (-1). As an illustration, the complex number 2+3i is made up of the real number 2 (Re) and the imaginary number 3i (Im).

The real and imaginary halves of a complex number are represented by the first and second values, respectively, of the complex data type in Python.

Algebraic expressions involving radicals are known as radical expressions.  The root of an algebraic expression makes up the radical expressions (number, variables, or combination of both).

The main symbol attached to any algebraic expression is  x. Each radical expression consists of three separate components: first the "square root" sign itself serves as the radical sign.

The component of the expression inside the radical is known as the radicand

The degree outside the root indicates which root the radical refers to. Expressions without degree symbols have a degree of 2. A cube root is indicated by a degree of 3, a fourth root is shown by a degree of 4, and so on.

The probability that fewer than 58% of the residents in the sample enjoy riding roller coasters is b) 0.433.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

The mean value is 0.62

Z value formula is

z = (x' -mean)/([tex]\sqrt{n}[/tex])

Substituting the given values, we get -

sigma = Sqrt {[tex](x'-mean)^2[/tex]/n}

Sigma = sqrt { [tex](0.58-0.62)^2[/tex]/75} = 0.09

z = (0.58-0.62)/(0.09)

z = -0.433

The likelihood that less than 58% of the sample's residents enjoy going on roller coasters is 0.433.

Probability is the possibility that something will occur. The total number of conceivable outcomes.

The probability of an event is a number between 0 and 1, where, broadly speaking, 0 represents the event's impossibility and 1 implies certainty.

The average is 0.62.

The formula for the Z value is

Z = (x' – mean) ([tex]\sqrt{n}[/tex])

By substituting the provided values, we get -

Sigma Equals [tex]\sqrt{\frac{(x' - mean)^2}{n} }[/tex]

Sigma is equal to sqrt {[tex]{(0.58-062)^2/75[/tex]} = 0.09

The gradient of the line y = x - 10 is 1

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x).

Given the equation of a line is y = x - 10.

The general equation of the line is y = mx + c.

We now get the equation y = x – 10. This will give us the following results when we compare it to the previous line: m = 1 and c = -10.

As a result, the supplied line has a slope of 1.

We must now locate the intercepts. In order to get the y-intercept, let's first enter x = 0 in the equation y = x - 10.

Adding x = 0 to y = x – 10 results in y = – 10.

Therefore, the provided line's y-intercept is equal to -10.

Let's now enter y = 0 to determine the x-intercept in the equation y = x - 10.

By substituting y = 0 for y = x - 10, we obtain x - 10 = 0.

The result of adding 10 from one side to the other is x = 10.

Therefore, the provided line's x-intercept is 10.

The 5th equivalent fraction to 1/5 is 5/25.

An equivalent fraction is a fraction that has the same value as another fraction, but a different numerator and denominator. There are an infinite number of equivalent fractions for any given fraction. To find the 5th equivalent fraction to 1/5, you can use the fact that equivalent fractions have a common multiple as a denominator.

The first step is to find a common multiple of the denominators of the fractions you want to compare. In this case, the denominator of the first fraction is 5, and you are looking for the 5th multiple of 5, which is 5*5 = 25.

The next step is to find the numerator that corresponds to the common denominator found in step 1. To do this, you can use the concept of cross-multiplication: the product of the original denominator and the new numerator is equal to the product of the original numerator and the new denominator.

1/5 * 5/5 = 1 * 5/5 * 5 = 5/25

So such a triangle cannot exist. And the sides can't be that lengths.

Thank you! :))

No, the sides of a triangle cannot have lengths 8, 16, and 18.

What is known as a triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

This is because the length of any side of a triangle must be less than the sum of the other two sides and greater than the difference of the other two sides. This is called the triangle inequality theorem.

For a triangle with sides 8, 16, and 18, the side 8 is less than the sum of the other two sides 16+18=34, but greater than the difference of the other two sides 16-18=-2. Therefore, the sides of a triangle cannot have lengths 8, 16, and 18.

Proof by contradiction is a kind of proof that demonstrates the truth or the validity of a proposition by showing that assuming the proposition to be false leads to a contradiction.

More broadly, proof by contradiction is a form of argument that shows a statement by arriving at a contradiction, even when the initial assumption is not the disproof of the statement to be proved. In general, proof by contradiction is also known as indirect proof.

A mathematical proof utilising proof by contradiction usually proceeds as follows:

1. The proposition to be proved is P.

2. We consider P to be false, i.e., we assume ¬P.

3. It is then shown that ¬P implies falsehood. This is typically accomplished by deriving two mutually contradictory assertions, Q and ¬Q, and appealing to the Law of noncontradiction.

4. Since assuming P to be false leads to a contradiction, it is concluded that P is, in fact, true.
