Any equation that does not contain a discontinuity, defined as a point where the graph of the equation has a sudden break or jump, is considered continuous. Examples of continuous equations include linear equations, polynomial equations, and exponential equations.

Continuity is an important concept in mathematics and related disciplines. A continuous equation is defined as any equation that does not contain a discontinuity, which is a point where the graph of the equation has a sudden break or jump. Discontinuous equations are equations with discontinuities that cause the graph of the equation to have sudden jumps or breaks. Linear equations, polynomial equations, and exponential equations are all examples of continuous equations, since they do not contain any discontinuities. Continuous equations are important because they are used in many areas of mathematics, such as calculus, to solve problems and understand the behavior of certain function

Answer:

Step-by-step explanation:

Let's call the two numbers x and y, where x is the smaller number and y is the larger number. We are given that x and y differ by 3, which means y - x = 3. We are also given that the product of x and y is 88, which means x * y = 88. We can solve this system of equations by substituting the second equation into the first equation:

y - x = 3

y = x + 3

Substituting this expression for y into the second equation, we get:

x * (x + 3) = 88

x^2 + 3x - 88 = 0

This is a quadratic equation that we can solve using the quadratic formula:

x = (-3 +/- sqrt(3^2 - 41(-88))) / (2*1)

= (-3 +/- sqrt(9 + 352)) / 2

= (-3 +/- sqrt(361)) / 2

= (-3 +/- 19) / 2

= -11/2 or 8/2

Therefore, the two numbers are x = -11/2 and y = 8/2, or x = -5.5 and y = 4. These are the solutions to the original system of equations.

The sum of roots of x2 + 5x + 6 = 0 is -5.

x2 + 5x + 6 = 0

To find the sum of roots, we need to factor the equation :

x2 + 5x + 6 = 0

x2 + 3x + 2x + 6

= 0

x(x + 3) + 2(x + 3)

= 0

(x + 3)(x + 2) = 0

x = -3, -2

Sum of Roots = -3 + (-2) = -5

x2 + 5x + 6 = 0

To find the sum of roots, we need to factorize the given equation. To do that, we can divide the equation into two parts, x2 + 3x and 2x + 6. We can factorize the first part as x(x + 3) and the second part as 2(x + 3). Then, we can multiply both parts to get the factorized equation, (x + 3)(x + 2) = 0. We can solve this equation to get the roots, x = -3 and -2. Finally, we can add both roots to get the sum of roots, -3 + (-2) = -5.

Either Pythagorean Theorem or the Law of Cosines is used to solve for y in a triangle, you can use either of these equations.

The Pythagorean Theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the longest side. This is written as:

                                            a2 + b2 = c2,

where a and b are the lengths of the two shorter sides, and c is the length of the longest side. In this equation, y is the length of the longest side.

The Law of Cosines states that:

                                          a2 = b2 + c2 - 2bc cos A

where A is the angle opposite side a. In this equation, y is side a.

Therefore, to solve for y in a triangle, you can use either the Pythagorean Theorem or the Law of Cosines, depending on the information given.

What is a sweepstake?

A sweepstake is a type of contest in which a prize or prizes are given to the winner or winners. Sweepstakes began as a type of lottery tied to the sale of a product. Sweepstakes became strictly "No purchase necessary to enter or win" and "A purchase will not increase your chances of winning" under these laws, especially because many sweepstakes companies skirted the law by stating only "no purchase necessary to enter," removing the consideration (one of the three legally required elements of gambling) to prevent sweepstakes abuse.

The quadratic equations are

b) x² - 5x + 6 = 0  ( the roots are x = 2 , x = 3 )

c) x² + 2x - 3 = 0  ( the roots are x = -3 , x = 1 )

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation in the standard form is ax² + bx + c = 0

Now , the value of A is

a)

Let the quadratic equation be x² + 5x - 6 = 0

Now , on simplifying the equation , we get

x² + 5x - 6 = 0

x² - x + 6x - 6 = 0

Taking the common factors in the equation , we get

x ( x - 1 ) + 6 ( x - 1 ) = 0

On factorizing the equation , we get

( x + 6 ) ( x - 1 ) = 0

So , ( x + 6 ) = 0 or ( x - 1 ) = 0

And , x = -6 or x = 1

So , the roots of the quadratic equations are x = -6 or x = 1

b)

Let the quadratic equation be x² - 5x + 6 = 0

Now , on simplifying the equation , we get

x² + 5x + 6 = 0

x² + 2x + 3x - 6 = 0

Taking the common factors in the equation , we get

x ( x + 2 ) + 3 ( x + 2 ) = 0

On factorizing the equation , we get

( x + 3 ) ( x + 2 ) = 0

So , ( x + 3 ) = 0 or ( x + 2 ) = 0

And , x = -3 or x = -2

So , the roots of the quadratic equations are x = -2 or x = -3

c)

Let the quadratic equation be x² + 2x - 3 = 0

Now , on simplifying the equation , we get

x² + 2x - 3 = 0

x² - x + 3x - 3 = 0

Taking the common factors in the equation , we get

x ( x - 1 ) + 3 ( x - 1 ) = 0

On factorizing the equation , we get

( x + 3 ) ( x - 1 ) = 0

So , ( x + 3 ) = 0 or ( x - 1 ) = 0

And , x = -3 or x = 1

Answer:

Step-by-step explanation:

When the population standard deviation is not known, the sample size needed for a confidence interval can be determined using the t-distribution.

The t-distribution is used to calculate the margin of error, which is the amount of variation that is allowed in the sample results. The sample size needed for a confidence interval is determined by calculating the critical value of the t-distribution for a given level of confidence and degree of freedom. The degree of freedom is the number of independent observations in the sample minus one.

The confidence level determines the critical value of the t-distribution, which is used to calculate the margin of error. The sample size is then calculated by dividing the margin of error by the desired confidence level. This method allows us to determine the sample size needed for a confidence interval even when the population standard deviation is unknown.

The value of k is -3, if x-1 is a factor of 4x³+3x² −4x + k

Quadratic Equation:

A quadratic equation is a second-order algebraic equation in x. The quadratic equation in standard form is ax2 + bx + c = 0. where a and b are the coefficients, x is the variable, and c is the constant term. The first condition of the quadratic equation is that the coefficients of x² are non-zero terms (a ≠ 0). To write a quadratic equation in standard form, first write the x² term, then the x term, and finally the constant term. The numbers for a, b, and c are generally written as whole numbers, not as fractions or decimals.

According to the Question:

Let P(x) = 4x³+3x² −4x + k

Given,  (x−1) is a factor of P(x)

x−1 = 0

x= 1

∴ p(1) = 4×(1)³+3×(1)² −4×(1)+k = 0

⇒ 4+3−4+k = 0

⇒ k+3=0

In such a case, each of the interior angles will have a measure of 60°

Since the angles of an equilateral triangle are the same, it is also known as an equiangular triangle.

A property of equilateral triangles includes that all of their angles are equal to 60°

The AAA Triangle Similarity Postulate asserts that if all of the angles in a triangle are equal to the corresponding angles in another triangle, then those two triangles are equal.

Since every equilateral triangle’s angles are, 60°every equilateral triangle is similar to one another due to this AAA Postulate.
