There are a total of 6 homework assignments that need to be completed one night. The number of ways to arrange n items in a specific order is n! (n factorial).

Therefore, for 6 homework assignments, the number of different orders in which they can be completed is 6! = 720.

This means that there are 720 different ways in which you can complete these 6 assignments on one night. Each permutation represents a unique order in which the assignments can be completed, such as starting with assignment 1, then 2, then 3, and so on, or starting with assignment 4, then 5, then 6, and then 1, and so on.

It is worth noting that this formula is only applicable when the order of the assignments matters. If the order of the assignments does not matter, then we would use the formula for combinations, which is n! / (r!(n-r)!).

Multiplying all of these options together results in 6 x 5 x 4 x 3 x 2 x 1 = 720 possible ways to complete the assignments in a different order. This is known as the permutation formula, which states that the number of ways to arrange n items in a specific order is n! (n factorial).

Answer:

Slope = 4/3

Step-by-step explanation:

The coordinates are,

→ x1 = 6, y1 = 0

→ x2 = 0, y2 = -8

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (-8 - 0)/(0 - 6)

→ m = (-8)/(-6)

→ m = 8/6

→ [ m = 4/3 ]

Hence, the slope is 4/3.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.

The three main sorts of fractions are as follows. Proper fractions, improper fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions. We categorize its kinds based on these two parameters.

The fractions are x/3y, x/6y and z(say)

The average cost per​ tape is 10.

The average cost is the ratio of the total of cost of all the products to the total number of products. We can calculate the average cost by dividing the total cost by the total output quantity.

The cost of manufacturing a particular videotape is :

C(x) = 9000+9x

Where

x is the number of tapes produced.

We need to find the value of average per tape i.e.  lim x →9000 C (x)

C (x) = 9000 + 9x

                 x

= 9000   + 9

   x    

Lim n→ 9000 C (x) = 9000    +9

The associated probabilities are A = At least two but no more than five buffers occupied.

There are a total of 2^6 = 64 possible outcomes when rolling 6 dice.

To find the probability of event A, we need to find the number of outcomes where at least two but no more than five buffers are occupied.

This can be done by summing the probabilities of each individual outcome where two, three, four, or five buffers are occupied and subtracting the probabilities where six or zero buffers are occupied.

The probability of two buffers being occupied is (6 choose 2)(1/64) = 15/64

The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64

The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64

The probability of five buffers being occupied is (6 choose 5)(1/64) = 6/64

So the probability of event A is (15/64) + (20/64) + (15/64) + (6/64) = 56/64.

B = At least three but no more than five buffers occupied.

To find the probability of event B, we need to find the number of outcomes where at least three but no more than five buffers are occupied.

This can be done by summing the probabilities of each individual outcome where three, four, or five buffers are occupied and subtracting the probability where six buffers are occupied.

The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64

The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64

The probability of five buffers being occupied is (6 choose 5)*(1/64) = 6/64

So the probability of event B is (20/64) + (15/64

y- intercept = - 26

Step-by-step explanation:

to find the y- intercept, obtain the equation of the line in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (34, - 52) and (x₂, y₂ ) = (68, - 78) ← 2 ordered pairs from the table

m = [tex]\frac{-78-(-52)}{68-34}[/tex] = [tex]\frac{-78+52}{34}[/tex] = [tex]\frac{-26}{34}[/tex] = - [tex]\frac{13}{17}[/tex] , then

y = - [tex]\frac{13}{17}[/tex] x + c

to find c substitute any of the ordered pairs into the equation and solve for c

x to the power of z:  2.00^3.00 = 8.00

x to the power of (y to the power of z):  2.00^(4.00^3.00) = 2.00^64.00 = 4096.00

The absolute value of (x minus y):  |2.00 - 4.00| = |-2.00| = 2.00

The square root of (x to the power of z):  √(2.00^3.00) = √8.00 = 4.00

Given three floating-point numbers x, y, and z, the output would be x to the power of z, x to the power of (y to the power of z), the absolute value of (x minus y), and the square root of (x to the power of z). The formula for each output is as follows:

x to the power of z:  x^z

x to the power of (y to the power of z):  x^(y^z)

The absolute value of (x minus y):  |x-y|

The square root of (x to the power of z):  √(x^z)

For example, if x = 2.00, y = 4.00, and z = 3.00, then the output would be:  8.00 4096.00 2.00 4.00

The calculation for each output is as follows:

x to the power of z:  2.00^3.00 = 8.00

x to the power of (y to the power of z):  2.00^(4.00^3.00) = 2.00^64.00 = 4096.00

The absolute value of (x minus y):  |2.00 - 4.00| = |-2.00| = 2.00

In this problem we find a parametric function with coordinates, that is, a vector of the form (x, y) = (f(t), g(x)) and we are supossed to determine the rectangular form of such function, that is, a function of the form:

y = f(x)

The rectangular form of the function is a line if and only if the resulting expression is of the form:

y = m · x + b

Where:

First, write the components of the parametric functions:

x = 2 · t + 3

y = 24 · t + 1

Second, clear variable t in each parametric expression:

t = (x - 3) / 2

t = (y - 1) / 24

Third, eliminate parameter t by transitive property:

(x - 3) / 2 = (y - 1) / 24

Fourth, obtain the equation of the line:

In order to calculate the acceleration of the object, we would apply the second equation of motion. Mathematically, the second equation of motion is given by this mathematical expression:

S = ut + ½at²

Where:  

At time, t = 1.00 seconds, the position is given by:

x₁ = 0 + 1/2(1²)a

x₁ = ¹/₂(a)

At time, t = 2.00 seconds, the position is given by:

A function that may reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y.

Given that the equation of the function is:

f(x) = √x + 7

Covert the given function into an equation:

y = √x + 7

Interchange the variables in the equation:

x = √y + 7

Isolate the value of y.

Subtract, 7 from both sides of the equation:

x - 7 = √y + 7 - 7

x - 7 = √y

Take square on both sides of the equation:

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2.

The range of sina(3cos2a cos4a 3sin2a sin2a cos2a) ^ tan a(sec a -sina tana) where a is not an integer multiple of 7t/2 can be calculated using the following formula:

Range = Maximum Value - Minimum Value

The expression inside the parentheses can be simplified to 3cos2a cos4a + 3sin2a sin4a and the expression inside the exponential can be simplified to tan2a (1 / cos2a - sin2a). This gives us the expression

Range = 3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)

To calculate the maximum and minimum values, we can use derivatives to find the critical points of the expression. Taking the first derivative with respect to a, we get

d/da (3cos2a cos4a + 3sin2a sin4a ^ tan2a (1 / cos2a - sin2a)) = 0

Solving this equation gives us the critical points of a = ±7t/6. Using these values, we can calculate the maximum and minimum values of the expression.

Maximum Value = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6)

Minimum Value = 3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6)

Finally, using the formula for the range, we can calculate the range of the expression to be

Range = 3cos14t/6 cos8t/6 + 3sin14t/6 sin8t/6 ^ tan4t/3 (1 / cos14t/6 - sin14t/6) - (3cos22t/6 cos16t/6 + 3sin22t/6 sin16t/6 ^ tan4t/3 (1 / cos22t/6 - sin22t/6))
