A gallon of milk costs $2.30. What is the cost per quart?

Any value in the interval (-∞,-2√5] ∪[2√5,∞) will cause the quadratic equation x2+bx+5 = 0 to have two real number solutions.

Given quadratic equation is:

[tex]x^{2} +bx+5=0[/tex]

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0.

To have two real number solutions the discriminant of a quadratic equation should be greater than or equal to zero.

[tex]D\geq 0[/tex]

[tex]b^{2} -4(1)(5)\geq 0[/tex]

[tex]b^{2}-20 \geq 0[/tex]

[tex]b^{2} -(2\sqrt{5}) ^{2}\geq 0[/tex]

[tex](b+2\sqrt{5} )(b-2\sqrt{5} )\geq 0[/tex]

b∈[tex](-\infty,-2\sqrt{5}][/tex]∪[tex][2\sqrt{5},\infty)[/tex]

Hence, any value in the interval (-∞,-2√5] ∪[2√5,∞) will cause the quadratic equation x2+bx+5 = 0 to have two real number solutions.

Answer:

$24.42

Step-by-step explanation:

3.14*r^2= area

3.14*1.2^2=4.52

5.40*4.52=24.42

Answer:

Step-by-step explanation:

Remark

First find the area of the circular piece of fabric. Then deal with cost per square foot.

Area of the fabric

Area =  pi * r^2

Area = 3.14 * 1.2^2

Area = 3.14 * 1.44

Area = 4.5216 square feet

Cost

1 square foot costs 5.40 dollars

4.5216 square feet costs x                   Cross multiply

x = 5.40 * 4.5216

Answerx = 24.42 dollars for the fabric bought.

For ellipses:

-First, let's use completing the square method to determine values of a(semi-major axis), b(semi-minor axis), and the coordinates of the center of the ellipse.

-The center of the ellipse is at C(5, 3), semi-major axis, a = 4, and semi-minor axis, b = 2.

-Since the major axis of the ellipse is horizontal, the distance between the center of the ellipse and the co-vertices of the ellipse is ±b.

-The coordinates of the co-vertices of the ellipse are:

For the parabola:

-We have the following data:

The parabola is opening to the left and axis symmetry along the major axis of the ellipse (axis of symmetry: y = 3):

The focus of the parabola is the center of the ellipses.

-The parabola is passing through the co-vertices of the ellipse:

-The parabola is passing through poînts (5, 5) and (5, 1)

-From the first data, we know that the value of k is equal to 3 because the axis of symmetry of the parabola is y = 3.

-From the second data, we know that the x-coordinate of the vertex is at h = 5 + a. (Note: the distance of the focus of the parabola and the vertex of the parabola is equal to ±a, since the parabola is opening the the left we use -a)

[tex]\mathsf{F=(5,3)}[/tex]

-Substitute the coordinates of the vertex of the parabola

-From the third data, we know that if the poînts lies on the parabola, the coordinates of the poînts must satisfy the equation of the parabola.

Using the point (5, 5), x = 5, y = 5:

-Another way to solve for the value of a is using the formula for the length of the latus rectum (LR = 4a). Since the length of the latus rectum is equal to the minor axis of the ellipse, we can easily solve for the value of a.

-Substitute the value of a in the equation:

The method which is used for every third person on a list of soccer players selected for a survey is known as systematic sampling.

The sampling method is the method of selecting the subset from the set to make a statical inference.

Because of its simplicity, systematic sampling, also known as the nth name selection approach, is frequently employed instead of random sampling. Following the collection of the sample, every nth person of the population is registered in the sample.

Thus, the systematic sampling method is used.

Percentages and decimals are closely related. As a matter of fact, we don't need to use any actual math to solve this question because there is a shortcut.

Answer by Dividing

One way to solve the question is by dividing. Percentages are numbers that represent a portion of 100. So, to find the decimal form we can divide the percentage by 100.

Shortcut

While dividing by 100 can work, there is an easier way to find the decimal form. Dividing by 100 will always be equivalent to moving the decimal point 2 digits to the left.

The probability that client D will be able to live to be 59 years old is 0.4.

Youe information is incomplete. Therefore, an overview of probability will be given.

Let's assume that there is an entire population of 50 people and the number of those that lives to 59 years is 20.

Therefore, the probability that can be deduced of those that live to 59 years will be:

= 20/50 × 100

= 2/5 × 100.

= 40%

The second statement is true. It is a reduction because 0 < n < 1.

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

Given: A triangle is dilated by a scale factor of n = 1/3. As n is less than 1 but greater than 0.

A dilation is a rigid transformation that forms an image that is the same shape as of the original figure but with a different size.  A dilation transforms a figure by scalar factor 'n' about the center of dilation is a fixed point in the plane which never changes.

A dilation that forms a larger image is known as enlargement.  A dilation that forms a smaller image is known as reduction.

• If n is greater than 1, then the image is an enlargement.

• If n is between 0 and 1, then the image is a reduction.

• If n is 1, the figure and then the image is exactly the same.

Hence the second statement is true. It is a reduction because 0 < n < 1.

I use the foil method, but if you need to use a different method you can look online at how it is done, but this should give you the correct answer.

First

Outside

Inside

Last

First you multiply 5x and 3x together (the first values in each bracket), which gives you 15x squared (15x^2)

Then you multiply the 5x and 3 (the values on the "outside" of the equation --> first and last) which gives you 15x

Then you multiply the "inside" values (the ones in the middle of all the terms), which is 2 and 3x, and gives you 6x

Last you multiply the 2 values that are last in each bracket, 2 and 3, which gives you 6

So then you put then in order of the exponent

15x^2+15x+6x+6

Then you collect like terms (which means terms that have the same number of the variable) and you're left with the answer

15x^2+21x+6

Then most likely you need to further simplify and you can common factor a number out (take the highest number that evenly mutiplies into each term and divide it out of each), so that you have,

3(5x^2+7x+2)

The graph of this equation runs through the point (2/3, 9/5), and it illustrates an inverse proportion, where y is inversely proportional to x.

An inverse proportion in mathematics is a relationship between two variables where a rise in one variable causes a fall in the other and vice versa. The two variables are thus inversely proportional to one another.

Let x be the independent variable and y be the dependent variable in an inverse proportion. Then the general form of an inverse proportion is:

y = k/x

where k is a constant of proportionality.

To find the specific formula for an inverse proportion that goes through the point (2/3, 9/5), we can substitute these values into the equation and solve for k:

y = k/x

9/5 = k/(2/3)

Multiplying both sides by (2/3), we get:

k = (9/5) * (2/3) = 6/5

Therefore, the specific formula for the inverse proportion is:

y = (6/5) / x

y = 6/(5x)

This equation represents an inverse proportion, where y is inversely proportional to x, and the graph of this equation passes through the point (2/3, 9/5).
