You have found the value of K when an equation has equal roots.

An equation is a mathematical statement that expresses the equality of two expressions. It is usually written in the form of an equation, which uses an equals sign ("=") between two expressions to show that they are equal. Equations can be used to solve for a single unknown value or to express a relationship between multiple variables. Equations can be used to model real-world situations and to solve problems.

When an equation has equal roots, that means that both of its roots are the same. This means that the equation can be written in the form of (x-K)^2 = 0, where K is the value of the root. To find K, you can take the square root of both sides of the equation to get x-K = 0. Then, by adding K to both sides, you can find that K equals x. Thus, you have found the value of K when an equation has equal roots.

If you doubled a penny every day, you would have $5,368,709.12

You can see that the decision is rather straightforward: having a single penny that doubles every day for a month are preferable to receiving $1 million upfront. This is due to compound interest's strength.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

It is thought that Italy in the 17th century is where the concept of "interest on interest" or compound interest first appeared. It will accelerate the growth of a total more quickly than simple interest, which is solely calculated on the principal sum.

Money multiplies more quickly thanks to compounding, and the more compounding periods there are, the higher the compound interest will be.

If I double this particular penny every day, I would have 30 extra pennies, plus my original one. I have $0.31 literal dollars

On day 30, if you doubled a penny every day, you would have $5,368,709.12.

The range of the function representing the baseball's height is 4 ≤ f(x) ≤ 24.

An equation is a mathematical statement that expresses the relationship between two or more quantities and usually contains one or more unknowns, represented by a letter or symbol. An equation is written in symbolic form and is used to solve a problem or to describe a physical law. Equations can be used to describe anything from simple arithmetic operations to complex scientific equations.

This is because the highest value of the function is f(x) = 24, which is the starting height of the ball before it is thrown, and the lowest value of the function is f(x) = 4, which is the height of the ball when it returns to the ground. Therefore, the range of the function is 4 ≤ f(x) ≤ 24.

To eliminate the x variable, you should multiply the equation by -(coefficient of x in the second equation)/(coefficient of x in the first equation)

One way of solving systems of linear equations is by using the method of elimination. This method involves adding or subtracting a multiple of one equation to the other in order to eliminate one of the variables.

In order to eliminate one of the variables, you should multiply the first equation by a coefficient that will make one of the variables in the first equation the opposite of the corresponding variable in the second equation when they are added.

For example, if you want to eliminate the variable x, you should multiply the first equation by a coefficient that makes the coefficient of x in the first equation the opposite of the coefficient of x in the second equation.

So if the equation is y = mx + b, to eliminate the x variable, you should multiply the equation by -(coefficient of x in the second equation)/(coefficient of x in the first equation).

It's important to note that you should be careful when choosing the coefficient, you should make sure that you don't divide by zero.

If Sarah answered 12 questions correctly, then there must have been 15 questions on the quiz in total. This is because 80% of 15 is 12. To calculate this, you would use the equation: (number of correct answers/total number of questions) x 100.

Since Sarah got 80%, if you plug in 12 for the number of correct answers, the total number of questions must be 15.   To check this answer, you can also use the equation: (percentage/100) x total number of questions = number of correct answers. If you plug in 80 for the percentage and 15 for the total number of questions, the answer would be 12, which is the number of correct answers Sarah got.

The probability that a number less than 1 will be rolled is 0 and the probability that the the number rolled will be less than 7 is 1

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Probability = sample space / total possible outcome

A fair die has 6 sides and each sides named from 1 to 6. Therefore the highest number one can get on a die is 6 and the least is 1

Therefore the probability to get a number less than 1 = 0/6 = 0

To find the value of the integral of [tex]{x}^{3}[/tex] from 0 to 2, we need to evaluate the definite integral:

[tex]\int_{0}^{2} {x}^{3} dx[/tex]

Using the power rule of integration, we can integrate the function as follows:

where C is the constant of integration.

Plugging in the limits of integration, we get:

[tex]\int_{0}^{2} {x}^{3} dx = \left[\frac{{x}^{4}}{4}\right]_{0}^{2}[/tex]

Simplify it like this: [tex]\frac{6}{30} :\frac{30}{30}[/tex] [tex]= \frac{1}{5}: \frac{1}{1}[/tex]    

You travel a fifth of a mile in 1 minute. Now you must find out how much it takes to get from [tex]\frac{1}{5}[/tex] to 21.

The polygon with vertices A(11, 3), (3, -11), C(-13, -9) and D(-5, 9) is a rhombus

The vertices of a polygon are the points where the sides of the polygon meet. A polygon is a closed shape that is made up of a finite number of straight line segments. The number of sides in a polygon is called its order or its degree.

The vertices of a polygon can be used to identify the shape of the polygon, for example a triangle with vertices (2,3), (4,5) and (6,7) are different from triangle with vertices (3,4), (5,6) and (7,8)

In addition, the vertices can be used to find the lengths of the sides of the polygon and to calculate its area and perimeter. Vertices can also be used to indicate the relative position of a polygon to other shapes or figures.

It's worth noting that the term "vertex" is also used to refer to the top of a pyramid or cone and the peak of a mountain. In these cases, it refers to the highest point of the object.

In this problem, the vertices A(11, 3), (3, -11), C(-13, -9) and D(-5, 9) when plotted on a graphing calculator shows that the two opposite sides are not equal to one another.

The ordered pairings (-2, 3), and (-5, 3), respectively, depict points along a horizontal line.

Let's go over some information on the horizontal line.

If the y-coordinates of every point along the line are equal, the line is horizontal.

The horizontal line's slope is zero and it is perpendicular to the x-axis.

Because the y-coordinates of every point on the line equal b, the equation of the horizontal line through point (a, b) is y = b.

Find the points with the same y-coordinates in order to identify the ordered pairs that represent points along a horizontal line.

Response A:

The paired numbers are (-2, 3), and (-5 , 3)

X is located between -2 and -5.

The difference in speed between Explorer B and Explorer A is 1440 miles per hour.

Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.

The speed formula is speed = distance / time.

Given;

Space Explorer B, flies 40000 miles in 20 hours

Average speed = total distance / total time

Average speed of Space Explorer B = 40000 / 20 = 2000 miles per hour

Average speed of Space Explorer A = 72,80 / 13 = 5,60 miles per hour
