Answer:

all whole numbers

all whole-number multiples of 125

Step-by-step explanation:

The domain and the range of a function is the set of input and output values of the function.

Let the number of tickets be x, and the revenue be y.

So, the revenue function will be:

\(\mathbf{y = 125x}\)

The number of tickets cannot be less than 0.

So, the domain of the revenue function is:

\(\mathbf{Domain = [0,\infty)}\)

The above means that, the domain is the set of all whole numbers

Similarly, the revenue cannot be less than 0.

So, the range of the revenue function is:

\(\mathbf{Range = [0,\infty)}\)

The above means that, the range is also the set of all whole numbers (in multiples of 125)

the following expressions are defined:

b) BC

c) \(B^T\)

d) B-C

e) A+B

f) \(BA^T\)

To determine which of the given expressions are defined, we need to consider the compatibility of matrix dimensions.

a) CA: Matrix multiplication is defined when the number of columns in the first matrix matches the number of rows in the second matrix. In this case, A is a 7x6 matrix and C is an 8x7 matrix. The number of columns in A (6) does not match the number of rows in C (8), so CA is not defined.

b) BC: Matrix multiplication is defined when the number of columns in the first matrix matches the number of rows in the second matrix. Both B and C are 7x6 matrices, so the number of columns in B (6) matches the number of rows in C (6). Therefore, BC is defined.

c) \(B^T\): The transpose of a matrix is defined for any matrix. So, \(B^T\)is defined.

d) B-C: Matrix subtraction is defined when the matrices have the same dimensions. Both B and C are 7x6 matrices, so B-C is defined.

e) A+B: Matrix addition is defined when the matrices have the same dimensions. Both A and B are 7x6 matrices, so A+B is defined.

f) \(BA^T\): Matrix multiplication is defined when the number of columns in the first matrix matches the number of rows in the second matrix. A is a 7x6 matrix, and \(A^T\)is a 6x7 matrix. The number of columns in A (6) matches the number of rows in \(A^T\) (6). Therefore, \(BA^T\) is defined.

So, the following expressions are defined:

b) BC

c) \(B^T\)

d) B-C

e) A+B

f) \(BA^T\)

The required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line is called a parabola.

Given that, a parabola has the directrix x=6 and the focus (3,-5), we need to find the equation of the parabola,

The standard form of a left-right parabola is given as:

4p(x-h) = (y-k)²

Focus = (p+h, k)

Therefore,

h+p = 3....(i)

Directrix =

x = h-p

h-p = 6...(ii)

Solving the equations we get,

h = 9/2

p = -3/2

Substitute into the standard form:

4p(x-h) = (y-k)²

4(-3/2)(x-9/2) = (y+5)²

-6(x-9/2) = (y+5)²

\(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

Hence, the required equation of the parabola in the vertex form is \(x = - \frac{1}{6} (y+5)^2+\frac{9}{2}\)

The solution of the given differential equation using the substitution u = y − 3x is:(1/6) * ln|y − 3x - 3/y − 3x + 3| = -x^3 + C, where C is the constant of integration.

Given: y′= 3/3x^2(y-3x)^2. Let u = y − 3xdy/dx = dy/du * du/dx= dy/du * 1/(d/dx(y-3x))= dy/du * 1/(-3)

Therefore, y′ = dy/du * 1/(-3)Substitute in the differential equationy′ = 3/3x^2(y-3x)^2dy/du * 1/(-3) = 3/3x^2(y-3x)^2.

Multiply both sides by -3du = -3x^2(y-3x)^2 dyWe get, du/dy = -3x^2/(y-3x)^2

Now differentiate u with respect to xu = y − 3xdu/dx = dy/dx - 3 => dy/dx = du/dx + 3

Putting the values of dy/dx and u into the differential equation, we get;du/dx + 3 = -3x^2/u^2du/dx = -3x^2/(u^2 - 9)

Integrate both sides by separating the variables∫[1/(u^2 - 9)]du = -∫3x^2dx= (1/6) * ln|u - 3/u + 3| = -x^3 + C. Substitute the value of u(=y − 3x) in the above expression and get the solution, C.

Therefore, the solution of the given differential equation using the substitution u = y − 3x is:(1/6) * ln|y − 3x - 3/y − 3x + 3| = -x^3 + C, where C is the constant of integration.

THE CORRECT ANSWER ON KHAN IS -9/4

For equation 3 + 2y = √(-y) the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

When Lea squares both sides of the equation 3 + 2y = √(-y), she gets:

(3 + 2y)² = (-y)

Expanding the left side, we get:

9 + 12y + 4y² = -y

Bringing all the terms to one side, we get a quadratic equation:

4y² + 13y + 9 = 0

We can solve this quadratic equation using the quadratic formula:

y = (-b ± √(b² - 4ac)) / 2a

Substituting the coefficients a = 4, b = 13, and c = 9, we get:

y = (-13 ± √(13² - 4(4)(9))) / 2(4)

y = (-13 ± √97) / 8

So the solutions are:

y = (-13 + √97) / 8 or y = (-13 - √97) / 8

Hence, the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8

The sampling method must be random. It's not specified in the problem whether the method of selecting the vehicles was random or not, so it's impossible to say whether this condition is met.

The sample size must be large enough. A sample size of 100 vehicles is considered to be large enough for the normal/large sample condition to be met.

The population must be approximately normally distributed or the sample size must be large. Since the problem does not specify anything about the distribution of the population, it is not clear if this condition is met.

Three decisions made by President Roosevelt were the implementation of Lend-Lease Act, decision to intern Japanese-Americans, establishment of Manhattan Project.

The Lend-Lease Act, enacted in 1941, allowed the United States to provide military aid to countries fighting against Axis powers. This policy was beneficial to the outcome of the war as it bolstered the resources and capabilities of Allied nations, helping them withstand Axis aggression. It played a crucial role in supporting countries like Britain, the Soviet Union, and China, strengthening their ability to resist Nazi Germany and Imperial Japan. However, the decision to intern Japanese-Americans was highly controversial and detrimental to the principles of civil liberties and human rights. Under Executive Order 9066, over 120,000 Japanese-Americans, mostly American citizens, were forcibly relocated and incarcerated in internment camps. This policy was widely criticized as discriminatory and a violation of constitutional rights. It had a significant impact on the affected individuals and their communities, causing long-lasting social and psychological consequences.

The establishment of the Manhattan Project, a top-secret research program aimed at developing atomic weapons, was a significant decision with far-reaching implications. The successful development of the atomic bomb under Roosevelt's leadership led to the eventual bombings of Hiroshima and Nagasaki. While this decision played a pivotal role in hastening Japan's surrender and effectively ending World War II, it also ushered in the nuclear age, raising complex ethical and geopolitical concerns regarding the use and proliferation of nuclear weapons.

Overall, President Roosevelt's decisions as Commander in Chief during World War II had a mixed impact. The Lend-Lease Act provided crucial support to Allied nations, contributing to the eventual victory against the Axis powers. However, the internment of Japanese-Americans and the development and use of atomic weapons had significant negative consequences, violating civil liberties and introducing new challenges and risks to the world. These decisions shaped not only the outcome of the war but also the future of the United States and the world, leaving a lasting legacy and lessons to be learned.

Company revenue quadratic function.

Angel

The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?

To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:

r(x) = a(x - h)^2 + k

where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

We can use the given revenue values to set up a system of three equations:

2.7 = a(0 - h)^2 + k

3.4 = a(1 - h)^2 + k

2.7 = a(6 - h)^2 + k

Subtracting the first equation from the second, and the first equation from the third, we get:

0.7 = a(1 - h)^2

0 = a(6 - h)^2

Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:

6 - h = 10

which gives us h = -4.

Substituting h = -4 into the first equation, we get:

2.7 = a(0 - (-4))^2 + k

2.7 = 16a + k

Substituting the revenue value for 2005, we get:

3.9 = a(3 - (-4))^2 + k

3.9 = 49a + k

Solving for a and k, we get:

a = -0.1

k = 4.3

Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:

r(x) = -0.1(x + 4)^2 + 4.3

The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?

We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:

3 - 4 + 5 - 6 + ... + 101

We can group the terms into pairs:

(3 - 4) + (5 - 6) + ... + (99 - 100) + 101

Each pair of terms adds up to -1, so we can simplify the expression to:

-1 -1 -1 ... -1 + 101

where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:

-50 + 101 = 51

Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

What is 12 7/8 - 56/17?

To subtract mixed numbers like 12 7/8, we first need to convert it to an improper fraction. We can do this by multiplying the whole number by the denominator of the fraction, and adding the result to the numerator. This gives us:

12 7/8 = (12 × 8 + 7)/8 = 103/8

Now we can subtract 56/17 from 103/8. To do this, we need to find a common denominator for the two fractions. The least common multiple of 8 and 17 is 136, so we can rewrite the fractions with this denominator:

103/8 = (103/8) × (17/17) = 1751/136

56/17 = (56/17) × (8/8) = 448/136

Now we can subtract the two fractions:

1751/136 - 448/136 = (1751 - 448)/136 = 1303/136

We can simplify this fraction by finding a common factor to divide both the numerator and denominator. Since both 1303 and 136 are relatively prime, we cannot simplify it any further. Therefore, the final answer is:

12 7/8 - 56/17 = 1303/136

A circle in the xy-plane has a diameter with endpoints (2,4) and (2,14). An equation of this circle is (x-2)^2+(y-9)^2=r^2 ,where r is a positive constant. What is the value of r?

The center of the circle is the midpoint of the diameter, which is at (2, (4+14)/2) = (2, 9). We can substitute this center point into the equation of the circle to get:

(x - 2)^2 + (y - 9)^2 = r^2

(2 - 2)^2 + (9 - 9)^2 = r^2

0 + 0 = r^2

So we see that r = 0. Therefore, the equation of the circle is just:

(x - 2)^2 + (y - 9)^2 = 0

This describes a single point in the xy-plane, which is the center of the circle. Note that this point is already on the given diameter, so it makes sense that the radius is zero.

  $4.64/gal

Step-by-step explanation:

€1.09/(1 L) × $1/(€0.89) × (1 L)/(0.264172 gal) ≈ $4.64/gal

__

To convert units, multiply by a fraction that has numerator and denominator equal, but with different units. The units you don't want should be placed in the fraction so they cancel the units in the measure you're converting.

Here, we want dollars per gallon. So, we start with the currency value and quantity we're given: euros per liter.

Since euros is in the numerator and we want dollars there, we multiply by a fraction that has dollars in the numerator and euros in the denominator: $1/€0.89.

We have liters in the denominator and we want gallons there. We can cancel the liters unit by putting it in the numerator of our conversion factor: (1 L)/(0.264172 gal).

Multiplying euros per liter by these two conversion factors give us the equivalent in dollars per gallon.

F = 9/5 C + 32

They want to know what -30°C is in Fahrenheit.

Fill in -30 for C in the equation.

F = 9/5 (-30) + 32

Multiply first, before adding. In order to multiply the fraction × the -30, times

-30 ×9 and then divide by 5. (Or for easier mental math, times -30÷5 and then times that answer (-6) times 9.)

F = -54 + 32

F = -22

This means that -30°C is the same as -22°F.

Four technicians make repairs when breakdowns occur on an automated production line. 20% of the breakdowns are serviced by Janet, 60% of the breakdowns are serviced by Tom, 15% of the breakdowns are serviced by Georgia, and 5% of the breakdowns are serviced by Peter.

When making repairs, each technician has a chance of making an incomplete repair. Janet makes an incomplete repair 1 time in 20, Tom makes an incomplete repair 1 time in 10, Georgia makes an incomplete repair 1 time in 10, and Peter makes an incomplete repair 1 time in 20.

If the next problem with the production line is diagnosed as being due to an initial repair that was incomplete, we can find the probability that the initial repair was made by each technician as follows:
- Probability that the initial repair was made by Janet: (20/100) x (1/20) = 0.001
- Probability that the initial repair was made by Tom: (60/100) x (1/10) = 0.006
- Probability that the initial repair was made by Georgia: (15/100) x (1/10) = 0.0015
- Probability that the initial repair was made by Peter: (5/100) x (1/20) = 0.00025

Therefore, the probability that the initial repair was made by Janet is 0.001, the probability that it was made by Tom is 0.006, the probability that it was made by Georgia is 0.0015, and the probability that it was made by Peter is 0.00025. The total probability is 0.00875.
