Answer:

negative infinity
negative infinity
Step-by-step explanation:
Real zeros are x values where the graph f(x) crosses the x-axis. Basically what values will you put in to get 0. There are 3 such values where the graph crosses the x axis.
You can see at we move right along the x -axis (x values towards infinity) the graph goes down and keeps going down, so we can say that it is going towards negative infinity in y direction because down is negative and up is positive. Same with the other side, as x values move towards left, graph moves down.

A painter can paint 3 small rooms in the same time it takes him to finish 1 large room and 1 small room. It takes him 7 hours to finish a large room. Find the number of hours it takes the painter to finish a small room.
Answers
Answer:
It's 3.5 hours. Or 3 hours and 30 minutes.
Step-by-step explanation:
If the painting of 3 small rooms takes as much time as the painting of 1 large and 1 small rooms then it takes the same amout of time to paint 1 large room and 2 small rooms.
7 hours = 1 large room
1 large room = 2 small rooms
1 small room is half the time of a large room
1/2 of 7 = 3.5
3.5 hours is 3 hours 30 minutes.

find the distance between the planes 5x−4y−z=65x−4y−z=6 and 4y−5x z=−484y−5x z=−48.
Answers
The distance between the two planes 5x−4y−z=65x−4y−z=6 and 4y−5x z=−484y−5x z=−48 is sqrt(7/10).
What is vector ?
A vector is a mathematical object that has both magnitude (or length) and direction. Vectors can be used to represent physical quantities such as velocity, force, or displacement, where the magnitude represents the size of the quantity and the direction represents its orientation in space.
Let n1 and n2 be the normal vectors of the two planes, respectively.
The normal vectors are:
n1 = <5, -4, -1> and n2 = <5, -4, 1>.
The projection of n1 onto n2 is:
projn1 onto n2 = (n1 . n2 / ||n2||^2) * n2 = (n1 . n2 / ||n2||^2) * (n2 / ||n2||) = (n1 . n2 / ||n2||) * n2 / ||n2|| = (n1 . n2) * n2 / ||n2||^2.
The dot product of n1 and n2 is:
n1 . n2 = 5 * 5 + (-4) * (-4) + (-1) * 1 = 25 + 16 + 1 = 42.
The magnitude of n2 is:
||n2|| = sqrt(5^2 + (-4)^2 + 1^2) = sqrt(30).
Therefore, the projection of n1 onto n2 is:
(n1 . n2) * n2 / ||n2||^2 = 42 * <5, -4, 1> / 30 = <7/3, -4/3, 7/30>.
So , The distance between the two planes 5x−4y−z=65x−4y−z=6 and 4y−5x z=−484y−5x z=−48 is sqrt(7/10).

what is the mode frequency of the age variable?
Answers
The mode frequency can be a useful tool for understanding the distribution of the data and identifying any outliers or anomalies in the data set.
The mode frequency of the age variable refers to the most frequently occurring age in a given set of data. This measure of central tendency is particularly useful when working with categorical data, such as age ranges.
To calculate the mode frequency, one must first organize the data into a frequency distribution table, which lists all the different ages and the number of times each occurs. The age with the highest frequency is then considered the mode frequency.
For example, if there are 100 individuals in a data set and the ages range from 20 to 60, we would organize the data into age ranges, such as 20-29, 30-39, etc. Then we would count how many individuals fall into each age range and record this information in the frequency distribution table.
If the age range with the highest frequency occurs more than once, we have a multi-modal data set. On the other hand, if there is only one mode frequency, the data set is considered unimodal.

Answers
Depending on the value of the definite integral of f(x) calculated between two limits, α and β, the area between two vertical lines can be positive, negative or zero.
The area between two vertical lines is given by the definite integral of a function f(x) calculated between two limits, α and β. In order to determine whether the area is positive, negative or zero, the values of the definite integral of f(x) calculated between two limits, α and β, must be known.
If the value of the definite integral of f(x) calculated between two limits, α and β, is greater than zero, then the area between the two vertical lines is positive. Mathematically, this can be expressed as:
Area = ∫βαf(x)dx > 0
Similarly, if the value of the definite integral of f(x) calculated between two limits, α and β, is less than zero, then the area between the two vertical lines is negative. Mathematically, this can be expressed as:
Area = ∫βαf(x)dx < 0
Lastly, if the value of the definite integral of f(x) calculated between two limits, α and β, is equal to zero, then the area between the two vertical lines is zero. Mathematically, this can be expressed as:
Area = ∫βαf(x)dx = 0
Therefore, depending on the value of the definite integral of f(x) calculated between two limits, α and β, the area between two vertical lines can be positive, negative or zero.

Answer:
m= -3/2
Step-by-step explanation:
To find slope
[tex]m \: = \frac{y2 - y1}{x2 - x1} [/tex]
We have our x1 and y1 of (2,5)
We have our x2 and y2 of (8,-4)
Now we plug in
= (-4-5)/(8-2)
= (-9)/(6)
Simplifying it would be
[tex]m = - \frac{3}{2} [/tex]
Answer: slope 'm' = -3 / 2
Step-by-step explanation: Using the formula m=(y2-y1)/(x2-x1), where 'm' is the slope of the line connecting the two points, we can plug in our x and y values:
x1 = 2
x2 = 8
y1 = 5
y2 = -4
Once we plug in our x and y values, we get the equation
m = (-4 - 5) / (8 - 2)

throwing the ball deep to the receivers _____ the wisest thing to do when it is third and long.
Answers
When it is third and long, the best move is typically to make a long pass to a wide receiver because it has the probability to gain the greatest yardage.
Throwing the ball far downfield is frequently the best move when the team has to gain a lot of yardage to continue the drive on third and long. The most yards may be gained by a deep pass to a wide receiver since it might extend the action past the original line of scrimmage. The prospect of a huge play, in which the receiver catches the ball and runs for a bigger gain, is also made possible. A deep pass might also throw the defense off because they might not be anticipating the offense to go for a long gain. But a deep pass can also be dangerous because it might result in a turnover if the receiver doesn't pay attention.

Adult tickets cost $17.95 and children’s tickets cost $12.95. Disney made $7355 from ticket sales from a total of 500 people. How many adults and children bought tickets?
Answers
Answer:
To figure out how many adults and children bought tickets, we can set up a system of equations using the information provided. Let x be the number of adults and y be the number of children. We know that:
x + y = 500 (because a total of 500 people bought tickets)
17.95x + 12.95y = 7355 (because the total revenue from ticket sales is $7355)
We can use the first equation to solve for one of the variables in terms of the other variable. For example, we can substitute y = 500 - x into the second equation:
17.95x + 12.95(500 - x) = 7355
This simplifies to:
17.95x + 6475 - 12.95x = 7355
5x = 1880
x = 376
so there are 376 adults bought tickets and 500-376=124 children bought tickets.

Answers
At a price of $44, the quantity demanded is equal to q*, which is 30 units.
The market for good X is given with a price of $15 at q0 (10 units), a price of $21 at pa, a price of $31 at p* (30 units), a price of $44 at pb, a price of $57 at p1 (50 units), and a price of $70 at q2 (70 units). To calculate the quantity demanded when the price is $44, we first need to identify the price points on either side of $44. In this case, $31 and $57 are the two price points. We then look at the corresponding quantities at those two points, which are q* (30 units) and q1 (50 units). Since the demand curve is downward sloping, the quantity demanded at $44 (pb) will be between 30 and 50 units. Since 30 is the lower number, the quantity demanded at $44 will be q*, or 30 units.

if v × w = 6 i − 7 j 9k, and v · w = 9, find tan where is the angle between v and w.
Answers
The tangent of the angle between vectors v and w is 2√(21) / 9
We can use the dot product and cross-product formulas to find the angle between two vectors.
The dot product of two vectors v and w is given by:
v · w = ||v|| ||w|| cos(θ)
where ||v|| and ||w|| are the magnitudes of the vectors v and w, and θ is the angle between them.
The cross product of two vectors v and w is given by:
v × w = ||v|| ||w|| sin(θ) k
where k is a unit vector in the direction of the cross product.
Since v × w = 6i - 7j + 9k and v · w = 9, we can find the angle between v and w as follows:
[tex]\theta = sin^{-1}\frac{||v \times w||}{||v|| \ ||w||} = sin^{-1}\frac{||6i - 7j + 9k||}{||v|| \ ||w||}[/tex]
We can find the magnitude of v × w by using the formula for the magnitude of a cross-product:
[tex]||v \times w|| = ||6i - 7j + 9k|| \\\\= \sqrt{6^2 + (-7)^2 + 9^2} = \sqrt{6^2 + 49 + 9^2}\\\\=\sqrt{84} = \sqrt(2^2 \times 3 \times 7) = 2\sqrt{(3 \times 7)[/tex]
We can find the magnitude of v and w using the given dot product formula:
v · w = ||v|| ||w|| cos(θ) = 9
||v|| ||w|| = 9 / cos(θ)
Since we know that ||v|| and ||w|| are positive, we can square both sides to obtain:
[tex](||v|| \ ||w||)^2 = \frac{9 }{cos(\theta))^2} \\\\||v||^2 \ ||w||^2 = \frac{81}{cos^2(\theta)}[/tex]
Finally, using the tangent formula, we can find tanθ:
tan(θ) = sin(θ) / cos(θ) = ||v × w|| / ||v·w|| = 2√(3 × 7) / 9 = 2√(21) / 9.

The standard deviation of a simple random sample of 15 customer waiting times is found to be 4.8 minutes. Find the test statistic to test the claim that the standard deviation of all customer waiting times is greater than 3.5 minutes. Use a 0.01 significance level.
Answers
The test statistic to test the claim that the standard deviation of all customer waiting times is greater than 3.5 minutes, 7.444
What is Standard deviation ?Standard deviation is a measure of the spread or dispersion of a set of data. It quantifies how much the individual data points in a set deviate from the mean (average) value of the set. In other words, it tells you how much the data is scattered around the mean.
The test statistic to test the claim that the standard deviation of all customer waiting times is greater than 3.5 minutes can be calculated using the following formula:
Z = (s / σ) x √n
where s is the sample standard deviation (4.8 minutes), σ is the population standard deviation (3.5 minutes), and n is the sample size (15).
Z = (4.8 / 3.5) x √15
= 7.444
So the test statistic is 7.444.
