The value of R(x) term is 36.
We are given that;
The equation x³ + 2x² - 72x - 28
Now,
We divide the first term, 8x, by the first term of d(x), which is x. This gives us 8, which is the third term of Q(x). We write 8 above the division bar and multiply it by d(x), which gives us 8x - 64. We subtract this from the new dividend, which gives us 36.
Since we cannot divide 36 by x-8 any further, we stop here and write 36 as the remainder R(x).

Answer:
D) As x increases, f(x) decreases; As x decreases, f(x) decreases
Step-by-step explanation:
To determine the end behavior of a function, it's worth noting the characteristics of the function.
As the function is clearly a parabola, given that the exponent is 2, this means that the function is even, which means as x increases, f(x) increases, and as x decreases, f(x) also increases. This is because for an even function, f(x)=-f(x). However, since the leading coefficient is negative, the parabola opens downwards, showing that as x increases, f(x) decreases, and as x decreases, f(x) decreases.
Therefore, D is correct. I've attached a graph to help you visualize what I've explained.

Read It PRACTICE ANOTHER
Based on the given information, the operating characteristics of Willow Brook National Bank's drive-up teller window can be determined and the probability of customers having to wait for service can be calculated.
The arrival rate for the drive-up teller window is 0.5 customers per minute, while the service rate is 0.75 customers per minute. Since both arrival and service times follow exponential distributions, we can use the formulas for an M/M/1 queue to calculate the operating characteristics.
(a) The probability of having no customers in the system can be found using the formula P0 = 1 - (λ/μ), where λ is the arrival rate and μ is the service rate. Plugging in the values, P0 = 1 - (0.5/0.75) = 0.3333.
(b) The average number of customers waiting can be calculated using the formula Lq = (\(\lambda ^2\)) / (μ(μ - λ)). Plugging in the values,
Lq = (\(0.5^2\)) / (0.75(0.75 - 0.5)) = 0.6667.
(c) The average number of customers in the system is given by L = λ / (μ - λ). Plugging in the values, L = 0.5 / (0.75 - 0.5) = 1.
(d) The average waiting time for a customer can be calculated using the formula Wq = Lq / λ. Plugging in the values, Wq = 0.6667 / 0.5 = 1.3333 minutes.
(e) The average time a customer spends in the system is given by W = Wq + (1 / μ). Plugging in the values, W = 1.3333 + (1 / 0.75) = 2.6667 minutes.
(f) The probability that arriving customers will have to wait for service can be calculated using the formula Pw = λ / μ. Plugging in the values, Pw = 0.5 / 0.75 = 0.6667.
These calculations provide the operating characteristics of the drive-up teller window at Willow Brook National Bank.

What do you mean by Division?Division is an arithmetic operation that is the reverse of multiplication. It is used to find the number of times a quantity is contained within another quantity. Division can be represented using the division symbol (÷) or a fraction bar (/) and is performed by dividing the dividend by the divisor. The result of division is the quotient, which represents the number of times the divisor fits into the dividend. For example, if you have 8 apples and you divide them into 4 equal parts, each part would contain 2 apples. The expression 8 ÷ 4 = 2 represents this division, where 8 is the dividend, 4 is the divisor, and 2 is the quotient.
First, we need to find out how many seedlings Lara can plant with the bag of soil she bought. To do this, we divide the total amount of soil by the amount of soil required for each seedling:
16.25 cups of soil ÷ 1.25 cups of soil per seedling = 13 seedlings
Next, we divide the total cost of the soil by the number of seedlings to find the cost of the soil per seedling:
$4.55 ÷ 13 seedlings = $0.35 per seedling.
Therefore, the cost of the soil for each seedling is $0.35.

Based on the calculation, it should be noted that the solution to the system of equations is x = 5.
How to solve the equationTo represent the costs (C) in dollars for x number of nights, we can use the equation:
C(x) = $500 (one-time preparation cost) + $10 (daily utility cost) * x (number of nights).
R(x) = $110 (rent per night) * x (number of nights).
Now, let's find the solution to the system of equations, which means finding the value of x where the costs equal the revenue:
C(x) = R(x)
Substitute the expressions for C(x) and R(x):
$500 + $10x = $110x.
To solve for x, we can move all the terms involving x to one side:
$110x - $10x = $500.
Combine like terms:
$100x = $500.
Now, divide both sides by 100 to isolate x:
x = $500 / 100.
x = 5.

Use Green's Theorem to find the counterclockwise circulation and outward flux for the field F=(8x−3y)i+(2y−3x)j and curve C : the square bounded by x=0,x=3,y=0, y=3 The flux is (Simplify your answer.) The circulation is (Simplify your answer.)
the counterclockwise circulation is also 0.Answer: The flux is 0. The circulation is 0.
Green's theorem is an important formula used in mathematics and physics to relate line integrals around a simple closed curve C to a double integral over the plane region D bounded by the curve C.
It states that for a vector field F in the plane, where F is continuously differentiable in a region containing D,
we have\($$\oint_C F\cdot dr = \iint_D \left(\frac{\partial F_2}{\partial x}-\frac{\partial F_1}{\partial y}\right)\,dx\,dy.$$
Here, F = (8x - 3y)i + (2y - 3x)j.\)
Therefore, \(F_1 = 8x - 3y and F_2 = 2y - 3x.\)
The curve C is a square with vertices at (0,0), (0,3), (3,3), and (3,0).
Let us first calculate the outward flux.
By Green's theorem,\($$\oint_C F\cdot dr = \iint_D \left(\frac{\partial F_2}{\partial x}-\frac{\partial F_1}{\partial y}\right)\,dx\,dy.$$$$\frac{\partial F_2}{\partial x}
= -3 \qquad \text{and} \qquad \frac{\partial F_1}{\partial y} = -3.$$\)
Thus,\($$\oint_C F\cdot dr = \iint_D (-3 + 3)\,dx\,dy = 0.$$\)
So, the outward flux is 0.
Next, let us calculate the counterclockwise circulation.
Again, by Green's theorem\(\(,$$\oint_C F\cdot dr = \iint_D \left(\frac{\partial F_2}{\partial x}-\frac{\partial F_1}\)
\({\partial y}\right)\,dx\,dy.$$$$\frac{\partial F_2}{\partial x} = -3 \qquad \text{and} \qquad \frac{\partial F_1}{\partial y} = -3.$$\)
Thus,\($$\oint_C F\cdot dr = \iint_D (-3 + 3)\,dx\,dy = 0.$$\)\)

5. Suppose X 1and X 2are random variables with mean 10,20 respectively, and SDs 2, 3 respectively.
Let T=11X 1−2X2
Find the mean and SD of T when X 1and X 2are independent.
Find the mean and SD of T when X1and X 2 have correlation of
−0.76
In the case that X1and X 2 are independent, normally distributed
variables, find P(T>30)
The mean of T is -10 and the standard deviation of T is √425 when X1 and X2 are independent.
To find the mean of T, we can use the properties of expected values. Since T = 11X1 - 2X2, the mean of T can be calculated as follows: E(T) = E(11X1) - E(2X2) = 11E(X1) - 2E(X2) = 11(10) - 2(20) = -10. To find the standard deviation of T, we need to consider the variances and covariance of X1 and X2. Since X1 and X2 are independent, the covariance between them is zero. Therefore, Var(T) = Var(11X1) + Var(-2X2) = 11^2Var(X1) + (-2)^2Var(X2) = 121(2^2) + 4(3^2) = 484 + 36 = 520. Thus, the standard deviation of T is √520, which simplifies to approximately √425. When X1 and X2 have a correlation of -0.76, the mean and standard deviation of T remain the same as in the case of independent variables. To calculate the probability P(T > 30) when X1 and X2 are independent, normally distributed variables, we need to convert T into a standard normal distribution. We can do this by subtracting the mean of T from 30 and dividing by the standard deviation of T. This gives us (30 - (-10))/√425, which simplifies to approximately 6.16. We can then look up the corresponding probability from the standard normal distribution table or use statistical software to find P(T > 30). The probability will be the area under the standard normal curve to the right of 6.16.

The equation of the plane is ax + by + cz + d = 0, where a = -1, b = -5, c = -5, and d = 11.
The equation of the plane that passes through points (1, 1, 1), (2, 0, 3), and (-1, 4, 2) can be found using the point-normal form of the equation of a plane.
To find the normal vector of the plane, we can take the cross product of two vectors formed by the given points. Let's call the vectors formed by (1, 1, 1) and (2, 0, 3) as vector A, and the vectors formed by (1, 1, 1) and (-1, 4, 2) as vector B.
Vector A = (2-1, 0-1, 3-1) = (1, -1, 2)
Vector B = (-1-1, 4-1, 2-1) = (-2, 3, 1)
Now, taking the cross product of A and B, we get the normal vector of the plane:
Normal vector = A x B = (1, -1, 2) x (-2, 3, 1) = (-1, -5, -5)
Using the normal vector and one of the given points (let's use (1, 1, 1)), we can write the equation of the plane as:
-1(x - 1) - 5(y - 1) - 5(z - 1) = 0
Simplifying the equation, we get:
-x - 5y - 5z + 11 = 0
