Jamal is asked to draw a circle. He is given the center and two points on the
circle, but he isn't told which point is which. The points are (-4,7), (3,6), and
(-1,3). Jamal draws the accurate circle from this information.
What is the equation of the circle he draws?

The roots of this quadratic equation are real and equal.

given equation:

[tex]x^{2}[/tex] - 6x + 9 =0

now we need to find discriminant

discriminant = D = [tex]b^{2}[/tex] - 4ac

from the given equation

a = 1

b = -6

c = 9

D = [tex](-6)^{2}[/tex] - 4(1)(9)

  = 36 - 36

D = 0

1.  [tex]b^{2}[/tex] - 4ac < 0 there roots are imaginary

2.  [tex]b^{2}[/tex] - 4ac = 0 there roots are real and equal

3. [tex]b^{2}[/tex] - 4ac >0  there roots are real and  distinct

The roots of this quadratic equation are real and equal.

A quadratic equation is graphically represented by a parabola with vertex located at the origin , below the x-axis , or above the x-axis . Therefore , a quadratic function may have one ,two or zero roots.

If the quadratic function is always more than zero that means, when graphed on coordinate system, the function never have intersects the

Answer:

-6r+48

Step-by-step explanation:

The answer above is what you end up when you use distributive property.

The point of intersection of these two lines is (2,1)

Point of intersection means the point at which two lines intersect.

These two lines are represented by the equation a1x + b1y + c1= 0 and    a2x + b2y + c2 = 0, respectively.

When the graphs of y = f(x) and y = g(x) intersect, both graphs have exactly the same x and y values.

So we can find the point or points of intersection by solving the equation f(x) = g(x)

We have been given that line l1  is horizontal and passes through the point (1,1). The line l2 is vertical and passes through points (2,2). We are asked to find a point of intersection between line l1 and line l2.  

Line l1 is a horizontal line so the y-coordinate will be 1 for any value of x. Line l2  is a vertical line, so the x-coordinate will be 2 for any value of y.

Based on Paul's batting scores for cricket in a season, his mean score to the nearest whole number is equal to 13.

In Mathematics, a mean is sometimes referred to as an average and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

Mathematically, the mean for this set of scores can be calculated by using the following formula:

Mean = [F(x)]/n

For the total scores, we have;

F(x) = 17 + 23 + 9 + 0 + 8 + 21 + 12

F(x) = 90.

Now, we can determine the mean score as follows;

Mean score = 90/7

Mean score = 12.86 ≈ 13.

h = size of the class interval

f₁ = frequency of the modal class

f₀ = frequency of the class preceding the modal class

f₂ = frequency of the class succeeding the modal class

The value that consistently appears in a given set is the mode. The mode or modal value in a data set is sometimes referred to as the value or number that occurs most frequently in the data set. In addition to mean and median, it is one of the three measures of central tendency.

A mode is described as the value in a group of values that occurs more frequently. The value that appears the most frequently is this one.

To find the mode we use the formula Mode = l + [(f₁-f₀)/(2f₁-f₀-f₂)] * h

Answer:

a) 27.9069767442

b} 75.439%

Step-by-step explanation:

No, the Square root of an integer is not always irrational because the square root of perfect squares is not irrational.

Any real number that cannot be written as p/q, where p and q are both integers, the quotient of two integers.

If a number is not a perfect square, the square root of that number is not rational.

For example, the square root is 4 is 2.

The square root of 9 is 3.

But whereas the square root of 5 is 2.23606797755555...... which is irrational

The square root of 8 is 2.8284271247555..... which is irrational.

Answer: 3,385.00

Step-by-step explanation: To find the number of student tickets sold, we need to first figure out the total number of tickets sold at the football game. We can do this by dividing the total amount of money collected by the cost of each ticket. In this case, we have:

Total number of tickets = 8,816.00 / (5.00 + 8.00)

                      = 8,816.00 / 13.00

                      = 677.5

Since the total number of tickets sold must be an integer, we can round this number down to 677. This means that 677 student tickets were sold at the football game.

We can verify this answer by calculating the total amount of money collected from the student tickets and checking that it is equal to the total amount collected at the game:

Total amount collected from student tickets = 677 * 5.00

                                          = 3,385.00

Since the total amount collected from the student tickets is less than the total amount collected at the game, we know that this is the correct answer.

We determine the mean and standard deviation for a statistical observation by considering the available data set and size of data.

In the statistics, the mean value is the average value of all available data set.

The standard deviation is an estimation that implies how far each data is apart from the mean value.

Suppose we have a list of data. The data list is denoted by X and the total number of data is N. Now we will add all the data set and the result is denoted by ∑X

Mean value formula = the sum of data / number of data = ∑X/N

In the next, we will determine the square value of all data and the list is denoted by X². Finally, we add all the X² and the result is ∑X²

now, standard deviation is calculated by the formula,

  standard deviation = √[∑X²/N - (∑X/N)²]

hence, we can solve for mean and SD

The answer is 40, by using addition.

Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division.The addition of two whole numbers results in the total amount or sum of those values combined. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (that is, "3 plus 2 is equal to 5").

Besides counting items, addition can also be defined and executed without referring to concrete objects, using abstractions called numbers instead, such as integers, real numbers and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces and subgroups.

Answer:

  C.) The only extreme point is (-1, 18).

Step-by-step explanation:

You want the local and global extrema of f(x) = -2x² - 4x + 16.

Unless the domain is restricted to a particular interval, the extrema of a polynomial function will be its turning points. The number of possible turning points is 1 less than the degree of the equation.

An even-degree polynomial equation will always have at least one global extreme on the domain of all real numbers.

The given 2nd-degree equation will have exactly one extreme point: its vertex at (-1, 18).

__

Additional comment

The vertex of ax² +bx +c is located at x=-b/(2a). Here, that is x=-(-4)/(2(-2)) = -1. The value of f(-1) is -2 -(-4) +16 = 18, so the extreme point is (-1, 18). A graphing calculator finds it quickly.

The lines y = - 4x + 5 and y = x + 4y = - 40 is neither parallel nor perpendicular.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, Are two lines y = - 4x + 5 and y = x + 4y = - 40.

Now,

x + 4y = 40

4y = - x + 40.

y = - (1/4)x + 10.

We know lines parallel to each other have the same slope and lines perpendicular to each other have a slope that is negative reciprocal of each other.
