what is Y=4x^2-4x+3 in parabola

Answer:

$352

Step-by-step explanation:

David Gave 1/5 of his money to charity

$2640 / 5 = $528

$2640 - $528 = $2112

1/3 of it to his mom

$2112 / 3 = $704

$2112 - $704 = $1408

He shared the rest of it among his 4 sisters equally

$1408 / 4 = $352

So, each of his sisters get $352

The area of a rectangle is calculated by multiplying its two sides together. This is because a rectangle is a shape with four straight sides, and the area of a rectangle is the amount of space inside the rectangle.

A rectangle is a four-sided shape with four right angles and four equal sides. It is a type of quadrilateral, which means it has four sides. Rectangles are the most common type of shape and can be found in many areas of life, from art to architecture and engineering. Rectangles are sometimes referred to as geometric shapes and are used to define and measure space.

The complete question is: How do you find an area with two sides?

The equation that can be used to find the cost, c, of the pizza is c/5 = $3.25.

An equation is a mathematical statement that shows that two expressions are equal. Equations use an equals sign (=) to show that the values of the expressions on either side of the sign are equal.

Equations can include variables, numbers, and mathematical operations such as addition, subtraction, multiplication, and division. The goal of solving an equation is to find the value of the variable that makes the equation true.

If they divide the cost of a meatball pizza evenly among 5 people and each person pays $3.25, then we can write the equation as

c/5 = $3.25

where c is the cost of the pizza

Plugging in the known value of p = $3.25, we get: c = 5($3.25) = $16.25.

So the cost of the meatball pizza at the Dancing Meatball is $16.25.

Answer:

Step-by-step explanation: by using the formula, volume of cylinder= πr2h

Answer:

Step-by-step explanation:

The measurement of the angle 7 is,

[tex]5+6+7=180\\ 5+90+7=180\\58+90+7=180\\ 7=180-90-58\\ 7=32[/tex]

Therefore, the desired angle is 32.

The values of Q(C1), Q(C2), and Q(C3) are 4, 4, and π, respectively.

The concept of the integral is a fundamental part of calculus and it is used to calculate the area under a curve or the volume of a 3-dimensional object. In this context, we will be exploring the integral of a two-dimensional set in the R^2 plane.

For every two-dimensional set C contained in R^2 for which the integral exists, the function Q(C) is defined as the double integral of the function (x^2 + y^2) over the set C. The double integral is a mathematical tool for finding the total volume under a surface.

Let's consider the three sets C1, C2, and C3 and find Q(C1), Q(C2), and Q(C3).

C1={(x,y) : −1 ≤ x ≤ 1, −1 ≤ y ≤ 1}

Q(C1) = ∬C1 (x^2 + y^2) dxdy = ∫^1_{-1}∫^1_{-1} (x^2 + y^2) dxdy = ∫^1_{-1} [(x^2 + y^2)/2]^1_{-1} dx = 4.

C2 ={(x,y):−1≤x≤1,−1≤y≤1}

Q(C2) = Q(C1) = 4.

C3 = {(x,y):x^2 + y^2 ≤1}

Q(C3) = ∬C3 (x^2 + y^2) dxdy = π.

In conclusion, the values of Q(C1), Q(C2), and Q(C3) are 4, 4, and π, respectively.

The correct answer is option c. 50%;

50% of scores in a normal distribution are above the mean.

A normal distribution is symmetrical, which means that the mean, median, and mode are all equal and that the percentage of scores below the mean is equal to the percentage of scores above the mean.

For a normal distribution with a mean of 40, exactly half of the scores (50%) will be above the mean, and the other half (50%) will be below the mean. This is true for any normal distribution, regardless of the standard deviation or any other characteristic of the distribution.

In a normal distribution, the data is symmetrically distributed around the mean. This means that if the mean is represented by a line, the same number of data points will be on either side of the line.

Mowing Andre's uncle's lawn paid better than the other two jobs.

The job that paid better compared to the others is mowing Andre's uncle's lawn. He earned $30 for 1 hour of work, which is more than the $10 he earned for mowing a neighbor's lawn for 1 hour or the $15 he earned each hour for mowing the community's lawn for 2 hours.

The thinking behind this is basic. The rate of pay for mowing Andre's uncle's lawn was higher than the rate of pay for the other two jobs.

This is still up in the air by isolating the sum earned by the number of hours worked.

For the uncle's lawn, the rate was $30/1 hour = $30 each hour.

For the neighbor's lawn, the rate was $10/1 hour = $10 each hour. Furthermore, for the community center's lawn, the rate was $30/2 hours = $15 each hour.

Therefore, Mowing Andre's uncle's lawn paid better compared to the next two jobs.

A stem-and-leaf diagram separates each value of a data set into two parts: the stem and the leaf.

The stem is the first part of the number, typically the largest place value, and it is used to group similar values together. The leaves are the last part of the number, typically the smallest place value, and they provide the specific values within each group.

For example, consider a data set with the values 15, 19, 10, 11, 15. In a stem-and-leaf diagram, the stem for these values would be 1 and the leaves would be 5, 9, 0, 1, and 5, respectively.

False. If the mean of "u" (unobserved ability) is independent of education, it only means that the average level of ability is not affected by the level of education. It does not imply that the average level of ability is the same for all levels of education.

In economics, "u" is often used to represent unobserved ability or talent, which can affect an individual's income or job performance. If the mean of "u" is independent of education, it means that the average level of ability is not affected by the level of education, i.e., the mean of "u" is the same for all individuals regardless of their level of education.

However, it does not imply that the average level of ability is the same for all levels of education.

For example, individuals with higher levels of education may have higher levels of "u" on average, due to factors such as better access to resources, more opportunities for learning and development, or self-selection of individuals with higher levels of "u" into higher levels of education.

In such a case, the mean of "u" would still be independent of education, but the average level of ability would not be the same for all levels of education.

The measure of the angle BCD is 60 degrees.

Ok, remember that the sum of the interior angles of a triangle is always equal to 180°.

And we can write the top angle at C as:

(5x + 10) + C = 180°

C = 180 - 5x - 10

Then the sum of the interior angles gives:

3x + 3x + (180 - 5x - 10) = 180

Now we can solve that for x to get:

6x -5x - 10 = 180 - 180

x - 10 = 0

x = 10

Then the measure of BCD is:

BCD = 5x + 10

The fly is located at the point having coordinates (2.00, 1.00) m

Cartesian and Polar Coordinates:

In the Cartesian system the coordinates are perpendicular to one another with the same unit length on both axes. A Polar coordinate system is determined by a fixed point, a origin or pole, and a zero direction or axis. Each point is determined by an angle and a distance relative to the zero axis and the origin.

If the cartesian coordinates of a point is given (x,y), the polar coordinates r,θ is given by the following relation

Take the wall as the xy plane so that the coordinates are x=2.00m and y=1.00m; and the fly is located at point P.

The distance between two points in the xy plane is

then let's change that. you don't want to stay a dumdum, right ?

midpoint. what does that mean ? it is the point exactly in the middle between 2 other points.

what does that mean to be in the middle between 2 other things ?

well, it means that the distance is the same to both other things. otherwise it would not be the middle.

therefore,

4.

QS = 56 ft

exactly the same distance as PQ.

PS = PQ + QS

because Q is the point in the middle between P and S.

it is really that simple.

5.

the line segment PQ is bisected (cut in half) by the line segment MN at point R.

so, we know what the intersection of PQ and MN did to PQ (cut PQ in half). but this does not tell us what it did to MN. it could be also one of the ends of MN that cut PQ in half. we simply don't know.

therefore, we cannot say anything about the midpoint of MN.

and therefore the first 2 answer options are not generally correct. they COULD be correct, but they could be also wrong. therefore they are mathematically and logically not a true statement per se. for that the statement needs to be true unconditionally = in all possible cases.

R is the midpoint of PQ. yes, correct. that's what is meant by being bisected or cut in half at that point.

since the 3rd answer option is correct, the 4th answer option (none of these) is incorrect.
