The leading term of the polynomial p(x) = 20 + 2x² - 8x³ is -8x³, the limit of p(x) as x approaches infinity is also negative infinity and the limit of p(x) as x approaches -0 is positive infinity.

(A) The leading term of the polynomial p(x) = 20 + 2x² - 8x³ is -8x³.

(B) To find the limit of the polynomial as x approaches infinity (∞), we examine the leading term. Since the leading term is -8x³, as x becomes larger and larger, the term dominates the other terms. Therefore, the limit of p(x) as x approaches infinity is also negative infinity.

(C) To find the limit of the polynomial as x approaches -0 (approaching 0 from the left), we again look at the leading term. As x approaches -0, the term -8x³ dominates the other terms, and since x is negative, the term becomes positive. Therefore, the limit of p(x) as x approaches -0 is positive infinity.

a) A nonzero vector orthogonal to the plane through the points P, Q, and R is N = (8, -9, 0). b) The area of triangle PQR is 1/2 * √145. c) The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 5.

a) To find a nonzero vector orthogonal to the plane through the points P, Q, and R, we can find the cross product of the vectors formed by subtracting one point from another.

Let's find two vectors in the plane, PQ and PR:

PQ = Q - P

= (2, 3, 2) - (-2, 1, 0)

= (4, 2, 2)

PR = R - P

= (1, 4, -1) - (-2, 1, 0)

= (3, 3, -1)

Now, we can find the cross product of PQ and PR:

N = PQ × PR

= (4, 2, 2) × (3, 3, -1)

Using the determinant method for the cross product, we have:

N = (2(3) - 2(-1), -1(3) - 2(3), 4(3) - 4(3))

= (8, -9, 0)

b) To find the area of triangle PQR, we can use the magnitude of the cross product of PQ and PR divided by 2.

The magnitude of N = (8, -9, 0) is:

√[tex](8^2 + (-9)^2 + 0^2)[/tex]

= √(64 + 81 + 0)

= √145

c) To find the volume of the parallelepiped with adjacent edges PQ, PR, and PS, we can use the scalar triple product.

The scalar triple product of PQ, PR, and PS is given by the absolute value of (PQ × PR) · PS.

Let's find PS:

PS = S - P

= (3, 6, 1) - (-2, 1, 0)

= (5, 5, 1)

Now, let's calculate the scalar triple product:

V = |(PQ × PR) · PS|

= |N · PS|

= |(8, -9, 0) · (5, 5, 1)|

Using the dot product, we have:

V = |(8 * 5) + (-9 * 5) + (0 * 1)|

= |40 - 45 + 0|

= |-5|

Malcolm's reasoning is correct because when comparing 8/11 and 7/10 using cross-multiplication, we find that 8/11 is indeed greater than 7/10.

Malcolm's reasoning is correct. To compare fractions, we can cross-multiply and compare the products. In this case, when we cross-multiply 8/11 and 7/10, we get 80/110 and 77/110, respectively. Since 80/110 is greater than 77/110, we can conclude that 8/11 is indeed greater than 7/10.

The joint PDF of X2 and X3 is constant within the region 0 < X2 < 1 and 0 < X3 < 1, and zero elsewhere.

To compute the sampling distribution of X2 and X3, we need to find the joint probability density function (PDF) of these two random variables.

Since X1, X2, and Xn are uniformly distributed on the interval (0, 1), their joint PDF is given by:

f(x1, x2, ..., xn) = 1, if 0 < xi < 1 for all i, and 0 otherwise

To find the joint PDF of X2 and X3, we need to integrate this joint PDF over all possible values of X1 and X4 through Xn. Since X1 does not appear in the joint PDF of X2 and X3, we can integrate it out as follows:

f(x2, x3) = ∫∫ f(x1, x2, x3, x4, ..., xn) dx1dx4...dxn

= ∫∫ 1 dx1dx4...dxn

= ∫0¹ ∫0¹ 1 dx1dx4

= 1

Therefore, the joint PDF of X2 and X3 is constant within the region 0 < X2 < 1 and 0 < X3 < 1, and zero elsewhere. This implies that X2 and X3 are independent and identically distributed (i.i.d.) random variables with a uniform distribution on (0, 1).

In other words, the sampling distribution of X2 and X3 is also a uniform distribution on the interval (0, 1).

The quotient is 3x^2 - x - 2.

To use synthetic division to find the quotient of (3x^3 - 7x^2 + 2x + 1) divided by (x - 2), we set up the synthetic division table as follows:

Copy code

  |   3    -7     2     1

2 |_____________________

First, we write down the coefficients of the dividend (3x^3 - 7x^2 + 2x + 1) in descending order: 3, -7, 2, 1. Then, we bring down the first coefficient, 3, as the first value in the second row.

Next, we multiply the divisor, 2, by the number in the second row and write the result below the next coefficient. Multiply: 2 * 3 = 6.

Copy code

  |   3    -7     2     1

2 | 6

Add the result, 6, to the next coefficient in the first row: -7 + 6 = -1. Write this value in the second row.

Copy code

  |   3    -7     2     1

2 | 6 -1

Again, multiply the divisor, 2, by the number in the second row and write the result below the next coefficient: 2 * (-1) = -2.

Copy code

  |   3    -7     2     1

2 | 6 -1 -2

Add the result, -2, to the next coefficient in the first row: 2 + (-2) = 0. Write this value in the second row.

Copy code

  |   3    -7     2     1

2 | 6 -1 -2 0

The bottom row represents the coefficients of the resulting polynomial after the synthetic division. The first value, 6, is the coefficient of x^2, the second value, -1, is the coefficient of x, and the third value, -2, is the constant term.

Thus, the quotient of (3x^3 - 7x^2 + 2x + 1) divided by (x - 2) is:

3x^2 - x - 2

The probability that the machine will function between 50 and 150 hours without a major breakdown is 0.3736.

The probability that it will work another extra 20 hours properly is 0.0648.

To solve these questions, we can use the properties of the exponential distribution. The exponential distribution is often used to model the time between events in a Poisson process, such as the time between major breakdowns of a machine in this case.

For an exponential distribution with a mean value of λ, the probability density function (PDF) is given by:

f(x) = λ * e^(-λx)

where x is the time, and e is the base of the natural logarithm.

The cumulative distribution function (CDF) for the exponential distribution is:

F(x) = 1 - e^(-λx)

Q7) To find this probability, we need to calculate the difference between the CDF values at 150 hours and 50 hours.

Let λ be the rate parameter, which is equal to 1/mean. In this case, λ = 1/100 = 0.01.

P(50 ≤ X ≤ 150) = F(150) - F(50)

= (1 - e^(-0.01 * 150)) - (1 - e^(-0.01 * 50))

= e^(-0.01 * 50) - e^(-0.01 * 150)

≈ 0.3935 - 0.0199

≈ 0.3736

Q8) In this case, we need to calculate the probability that the machine functions between 100 and 120 hours without a major breakdown.

P(100 ≤ X ≤ 120) = F(120) - F(100)

= (1 - e^(-0.01 * 120)) - (1 - e^(-0.01 * 100))

= e^(-0.01 * 100) - e^(-0.01 * 120)

To calculate the future value of $12,250 after 8 years with an annual interest rate of 4% compounded quarterly, we can use the formula for compound interest:

FV = PV * (1 + r/n)^(n*t)

Where:

FV is the future value

PV is the present value (initial amount)

r is the annual interest rate (in decimal form)

n is the number of compounding periods per year

t is the number of years

Given:

PV = $12,250

r = 4% = 0.04 (as a decimal)

n = 4 (compounded quarterly)

t = 8 years

Plugging in these values into the formula, we get:

FV = $12,250 * (1 + 0.04/4)^(4*8)

= $12,250 * (1 + 0.01)^(32)

= $12,250 * (1.01)^(32)

Using a calculator, we can evaluate this expression to find the future value:

FV ≈ $12,250 * 1.349858807576003

FV ≈ $16,495.11

a. The function for Above the Bored's monthly profit is P(x) = $226x.

b. Above the Bored will have a net profit of $39,098.

c. Above the Bored needs to sell a minimum of 1 wakeboard in a month to break even.

(a) To find the function P(x) for Above the Bored's monthly profit, we need to subtract the cost of producing x wakeboards from the revenue generated by selling x wakeboards.

Revenue = Selling price per wakeboard * Number of wakeboards sold

Revenue = $480 * x

Cost = Cost per wakeboard * Number of wakeboards produced

Cost = $254 * x

Profit = Revenue - Cost

P(x) = $480x - $254x

P(x) = $226x

Therefore, the function for Above the Bored's monthly profit is P(x) = $226x.

(b) If Above the Bored produces and sells 173 wakeboards in a month, we can substitute x = 173 into the profit function to find the net profit:

P(173) = $226 * 173

P(173) = $39,098

Therefore, for that month, Above the Bored will have a net profit of $39,098.

(c) To break even, Above the Bored needs to have a profit of $0. In other words, the revenue generated must equal the cost incurred.

Setting P(x) = 0, we can solve for x:

$226x = 0

x = 0

Since the number of wakeboards cannot be zero (as it is not possible to sell no wakeboards), the minimum number of wakeboards Above the Bored needs to sell in a month to break even is 1.

Therefore, Above the Bored needs to sell a minimum of 1 wakeboard in a month to break even.

To approximate the number of sandwiches the deli manager should anticipate selling when 178 customers visit the deli, we can use the given data to estimate the linear relationship between the number of customers and the number of sandwiches sold.

We can start by calculating the average number of sandwiches sold per customer based on the data provided:

Total number of customers = 104 + 70 + 111 + 74 + 170 + 114 + 199 + 133 + 163 + 109 + 131 + 90 = 1558

Total number of sandwiches sold = Sum of sandwich data = 104 + 70 + 111 + 74 + 170 + 114 + 199 + 133 + 163 + 109 + 131 + 90 = 1498

Average sandwiches per customer = Total number of sandwiches sold / Total number of customers = 1498 / 1558 ≈ 0.961

Now, we can estimate the number of sandwiches for 178 customers by multiplying the average sandwiches per customer by the number of customers:

Number of sandwiches ≈ Average sandwiches per customer × Number of customers

Number of sandwiches ≈ 0.961 × 178 ≈ 172.358

To calculate the number of heavy equipment operators, let's assume the number of heavy equipment operators as "x" and the number of general laborers as "y."

The cost of hiring a heavy equipment operator per day is $120, and the cost of hiring a general laborer per day is $93.

We can set up two equations based on the given information:

Equation 1: x + y = 40 (since a total of 40 people were hired)

Equation 2: 120x + 93y = 4746 (since the total payroll was $4746)

To solve these equations, we can use the substitution method.

From Equation 1, we can solve for y:

y = 40 - x

Substituting this into Equation 2:

120x + 93(40 - x) = 4746

120x + 3720 - 93x = 4746

27x = 1026

x = 38

Substituting the value of x back into Equation 1, we can find y:

Multiplying both sides of the equation by |x|, we have |x|y' + y = 3xcos(2x). Now, we can rewrite the left side as (|x|y)' = 3xcos(2x). Integrating both sides with respect to x, we get |x|y = ∫(3xcos(2x))dx. Evaluating the integral and simplifying, we obtain |x|y = (3/2)sin(2x) + C, where C is the constant of integration. Dividing both sides by |x|, we finally have y = (3/2)(sin(2x)/|x|) + C/|x|.

(b) To solve the differential equation xy' + 2y = e^x, we can use the method of integrating factors. The integrating factor is given by μ(x) = e^(∫(2/x)dx) = e^(2ln|x|) = |x|^2.

To find the transformed function g(x), we need to apply the transformations to f(x) one by one.

Step 1: Vertical compression of factor 1/3This compression will cause the graph to shrink vertically by a factor of 1/3. This means the y-values will be one-third of their original values, while the x-values remain the same. We can achieve this by multiplying the function by 1/3. Therefore, the function will now be g(x) = (1/3) * f(x)

Step 2: Translation of 3 units upThis translation will move the graph 3 units up along the y-axis. This means that we need to add 3 to the function g(x) that we got from the previous step.

The transformed function g(x) will be:g(x) = (1/3) * f(x) + 3 Substituting f(x) = 1/x, we getg(x) = (1/3) * (1/x) + 3g(x) = 1/(3x) + 3Hence, the transformed function g(x) is g(x) = 1/(3x) + 3.

Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100%

To determine the system capacity and the bottleneck stage and utilization of Stage 3:

The system capacity is calculated by the product of the processing capacity of each stage:

1 x 1 x 2 = 2 units per minute

The bottleneck stage is the stage with the lowest capacity and it is Stage A. Therefore, Stage A has the lowest capacity and determines the system capacity.The utilization of Stage 3 can be calculated as the processing time per unit divided by the available time per unit:

Process time per unit = 1 + 2 + 3 = 6 minutes per unit

Available time per unit = 90% x 100% x 100% = 0.9 x 1 x 1 = 0.9 minutes per unit

The utilization of Stage 3 is, therefore, (6/0.9) x 100% = 666.67%.

However, utilization cannot be greater than 100%, so the actual utilization of Stage 3 is 100%.

To show that it is not one-to-one, we need to demonstrate that there exist two different polynomials in S that map to the same derivative. Consider two polynomials in S: f(x) = x^2 and g(x) = x^2 + 1. The derivatives of both f(x) and g(x) are equal to 2x. Therefore, the function maps both f(x) and g(x) to the same derivative, indicating that it is not one-to-one.

On the other hand, the function is onto. This means that for any polynomial in T (which is a set of polynomials with real coefficients), there exists at least one polynomial in S that maps to it. In this case, for any polynomial g(x) in T, we can find a polynomial f(x) in S such that f'(x) = g(x). We can choose f(x) to be the antiderivative of g(x), which exists since g(x) is a polynomial. Therefore, the function is onto.

The derivative of the function y = (x² + 4x + 3)/(√x) is shown below:

Given function,y = (x² + 4x + 3)/(√x)We can rewrite the given function as y = (x² + 4x + 3) * x^(-1/2)

Hence, y = (x² + 4x + 3) * x^(-1/2)

We can use the Quotient Rule of Differentiation to differentiate the above function.

Hence, the derivative of the given function y = (x² + 4x + 3)/(√x) is

dy/dx = [(2x + 4) * x^(1/2) - (x² + 4x + 3) * (1/2) * x^(-1/2)] / x = [2x(x + 2) - (x² + 4x + 3)] / [2x^(3/2)]

We simplify the expression, dy/dx = (x - 1) / [x^(3/2)]

Hence, the derivative of the given function y = (x² + 4x + 3)/(√x) is

(x - 1) / [x^(3/2)].

The derivative of the function f(x) = [(1/x²) - (3/x^4)](x + 5x³) is shown below:

Given function, f(x) = [(1/x²) - (3/x^4)](x + 5x³)

We can use the Product Rule of Differentiation to differentiate the above function.

Hence, the derivative of the given function f(x) = [(1/x²) - (3/x^4)](x + 5x³) is

df/dx = [(1/x²) - (3/x^4)] * (3x² + 1) + [(1/x²) - (3/x^4)] * 15x²

We simplify the expression, df/dx = [(1/x²) - (3/x^4)] * [3x² + 1 + 15x²]

Hence, the derivative of the given function f(x) = [(1/x²) - (3/x^4)](x + 5x³) is

[(1/x²) - (3/x^4)] * [3x² + 1 + 15x²].

Step-by-step explanation:

The answer ic C plug log into th calculator

The slope of the line that passes through the points (8, 4) and (5, 3) is 1/3.

To find the slope of a line with two given points, you can use the formula:

slope = (y2 - y1) / (x2 - x1)

Let's take the points (8, 4) and (5, 3) as an example.

1. Identify the coordinates of the two points: (x1, y1) = (8, 4) and (x2, y2) = (5, 3).

2. Substitute the coordinates into the slope formula:

slope = (3 - 4) / (5 - 8)

3. Simplify the equation:

slope = -1 / -3

4. Simplify further by multiplying the numerator and denominator by -1:

slope = 1 / 3

Therefore, the slope of the line that passes through the points (8, 4) and (5, 3) is 1/3.

To find the slope with three points, you would need to use a different method, such as finding the equation of the line and then calculating the slope from that equation. If you provide the three points, I can guide you through the process.

Remember, slope represents the steepness or incline of a line. A positive slope indicates an upward trend, while a negative slope indicates a downward trend. A slope of zero represents a horizontal line, and an undefined slope represents a vertical line.

The difference in their commute distances is 1654 meters.

To compare Mikko's commute distance of 8 km to Jason's commute distance of 6 miles, we need to convert one of the distances to the same unit as the other.

Given that 1 mile is equal to 1609 meters, we can convert Jason's commute distance to kilometers:

6 miles * 1609 meters/mile = 9654 meters

Now we can calculate the difference in their commute distances:

Difference = Mikko's distance - Jason's distance

         = 8 km - 9654 meters

To perform the subtraction, we need to convert Mikko's distance to meters:

8 km * 1000 meters/km = 8000 meters

Now we can calculate the difference:

Difference = 8000 meters - 9654 meters

         = -1654 meters

The negative sign indicates that Jason's commute distance is greater than Mikko's commute distance.

Therefore, their commute distances differ by 1654 metres.

Answer:

100 Billion

Step-by-step explanation:

Let's say the number of planets is equal to P.

[tex]P = x^{2} - (m^4+15)\\x = 14\\m = 3[/tex]

Now we substitute 14 and 3 for x and m in the first equation.

[tex]P = 14^2-(3^4+15)\\P = 196-(81+15)\\P = 196-96\\P = 100[/tex]

The question said in billions, so the answer would be 100 billion which is the first option.

The selling price should be $9054.61 to recoup the income that the rental company loses by selling the equipment "early."

a) It is an annuity due problem.

An annuity due is a sequence of payments, made at the start of each period for a fixed period.

For instance, rent on a property, which is usually paid in advance at the start of the month and continues for a set period, is an annuity due.

In an annuity due, each payment is made at the start of the period, and the amount does not change over time since it is an agreed-upon lease agreement.

Now, the selling price can be calculated using the following formula:

[tex]PMT(1 + i)[\frac{1 - (1 + i)^{-n}}{i}][/tex]

Here,

PMT = Monthly

Rent = $200

i = Rate per period

= 4.4% per annum/12

n = Number of Periods

= 4.5 * 12 (since 4 and a half years of useful life are left).

= 54

Substituting the values in the formula, we get:

[tex]$$PMT(1+i)\left[\frac{1-(1+i)^{-n}}{i}\right]$$$$=200(1+0.044/12)\left[\frac{1-(1+0.044/12)^{-54}}{0.044/12}\right]$$$$=200(1.003667)\left[\frac{1-(1.003667)^{-54}}{0.00366667}\right]$$$$= 9054.61$$[/tex]

Therefore, the selling price should be $9054.61 to recoup the income that the rental company loses by selling the equipment "early."
