Answer:

2.50

Step-by-step explanation:

The marginal revenue when output rises from 310 to 370 pounds is $1.75 per pound.

Given that a table containing Total Output (Q), Price per Pound ($1.50), Total Revenue we need to find the marginal Revenue when output rises from 310 to 370 pounds.

To calculate marginal revenue, we need to determine the change in total revenue when output increases from 310 to 370 pounds.

Total revenue at 310 pounds = $555.00

Total revenue at 370 pounds = $660.00

Change in total revenue = $660.00 - $555.00 = $105.00

Since the change in total revenue is $105.00 and the change in output is 60 pounds, we can calculate marginal revenue as:

Marginal Revenue = Change in Total Revenue / Change in Output

= $105.00 / 60 pounds

= $1.75 per pound

Hence the marginal revenue when output rises from 310 to 370 pounds is $1.75 per pound.

Answer:
it took Sean 3 hours to write the essay.

Step-by-step explanation:

We know that the ratio of time Sean spent writing the essay to the time he spent revising the essay was 4:1, which means that for every 4 units of time he spent writing the essay, he spent 1 unit of time revising it.

Let's call the time he spent writing the essay "x" and the time he spent revising the essay "y". We know that x + y = 15 (because he spent a total time of 15 hours writing and revising the essay) and that the ratio of x to y is 4:1, so 4x = y.

We can substitute the second equation into the first equation:

x + 4x = 15

5x = 15

x = 3

So it took Sean 3 hours to write the essay.

The correct option in the given situation is (C) there are twice as many terms in sequence y as there are in sequence x.

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important.

Similar to a set, it has members (also called elements, or terms).

The length of the series is the number of elements (potentially infinite).

In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important.

A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.

An indexed family, which is a function from any index set, can be thought of as a generalization of the idea of a sequence.

So, we have:

x: begin at 2, add 3 = 5

y: begin at 4, add 6 = 10

According to the given statements, the best statement going with the situation is (C) the terms in sequence y are two times the terms in sequence x.

Therefore, the correct option in the given situation is (C) there are twice as many terms in sequence y as there are in sequence x.

Answer: [tex]y=4x+50[/tex]

Step-by-step explanation:

During Week 0, the number of specialty items that were produced at the old factory than at the new factory is 46 specialty items.

The growth rate for the old factory is 0.08 or 8%.

The weekly number of specialty items produced at the new factory would exceed the weekly number of specialty items produced at the old factory from the 5th week.

Mathematically, an equation which can be used to model an exponential growth rate is given by this mathematical expression:

A(t) = P(1 + r)^{t}    ......equation 1.

Where:

Based on the information provided, an exponential function that represents the number of specialty items that are produced at the old factory is given by:

P(w) = 236(1.08)^w     .......equation 2.

When week, w = 0, the number of specialty items that were produced at the old factory is:

P(0) = 236(1.08)^0

P(0) = 236 specialty items.

For the new factory, the number of specialty items is equal to the y-intercept of the given graph, which is equal to 190 specialty items.

Therefore, the difference = 236 - 190 = 46 specialty items.

For the growth rate for the old factory, we would compare equation 1 and equation 2 as follows:

1 + r = 1.08

Growth rate, r = 1.08 - 1

Growth rate, r = 0.08 or 8%.

Next, we would determine the exponential function that represents the new factory:

505 = 190(1 + r)^7

505/190 = (1 + r)^7

Growth rate, r = (505/190)^{1/7} - 1

Growth rate, r = 1.1499 - 1,

Growth rate, r = 0.1499 ≈ 0.15 or 15%.

Therefore, the function is given by q(w) = 190(1.15)^w.

When the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory, we have:

190(1.15)^w > 236(1.08)^w

(1.15)^w/(1.08)^w > 236/190

1.0648^w > 1.2421

Taking the ln of both sides, we have:

w > ln(1.2421)/ln(1.0648)

w > 4.3

According to the given time card the pay for the day is $96.25.

To calculate the pay for a day, we need to determine the total number of hours worked for that day. We can do this by subtracting the start time from the end time for each shift.

In the morning, the start time is 8:00 and the end time is 12:00, so the number of hours worked is 12:00 - 8:00 = 4 hours.

In the afternoon, the start time is 12:45 and the end time is 17:30, so the number of hours worked is 17:30 - 12:45 = 4 hours and 45 minutes, which we can convert to decimal form by dividing 45 by 60 to get 0.75 hours.

The total number of hours worked is 4 + 4.75 = 8.75 hours.

Since the wage is $11/hr, the pay for the day is 8.75 hours * $11/hr = $96.25.

Rounding to the nearest hundredth, the pay for the day is $96.25.

a) At the instant when the radius of the oil slick is 100 centimeters and the height is 0.5 centimeters, the volume of the oil slick is given by V = πr^2h = π(100^2)(0.5) = 50,000π cubic centimeters.

Since the volume of the oil slick is increasing at the constant rate of 2000 cubic centimeters per minute, the rate of change of the height with respect to time can be found using the equation:

dV/dt = 2πrh dr/dt + 2πr^2 dh/dt

Setting r = 100 cm, h = 0.5 cm, dr/dt = 2.5 cm/min, and dV/dt = 2000 cm^3/min, we get:

2000 = 2π(100)(0.5) dr/dt + 2π(100^2) dh/dt

Solving for dh/dt, we get:

dh/dt = (2000 - 2π(100)(0.5) dr/dt)/(2π(100^2)) = (2000 - 500π dr/dt)/(200π)

Substituting dr/dt = 2.5 cm/min, we get:

dh/dt = (2000 - 500π * 2.5)/(200π) = (2000 - 1250)/200π = (850 - 1250)/200π = -400/200π cm/min

So, the rate of change of the height of the oil slick with respect to time at this instant is -0.63 cm/min.

b) Let t be the time elapsed since the recovery device began working. The volume of the oil slick at time t is given by:

V(t) = πr^2(h) = π(100^2 + 2.5t)^2(0.5 + 0.63t)

Since the rate of oil removed by the recovery device is R(t) = 400V(t) cubic centimeters per minute, the rate of change of the volume of the oil slick with respect to time is:

dV/dt = 2πr dr/dt h + 2πr^2 dh/dt - 400V(t)

Setting r = 100 + 2.5t, h = 0.5 + 0.63t, dr/dt = 2.5 cm/min, and dh/dt = 0.63 cm/min, and substituting into the equation, we get:

dV/dt = 2π(100 + 2.5t)(2.5) (0.5 + 0.63t) + 2π(100 + 2.5t)^2(0.63) - 400π(100 + 2.5t)^2(0.5 + 0.63t)

Since dV/dt = 2000 - 400V(t), we get:

2000 = 2π(100 + 2.5t)(2.5) (0.5 + 0.63t) + 2π(100 + 2.5t)^2(0.63) - 400π(100 + 2.5t)^2(0.5 + 0.63t) + 400V(t)

This is a nonlinear differential equation that can be solved using numerical methods to find the time when the oil slick reaches its maximum volume. The exact time when the oil slick reaches its maximum volume cannot be determined analytically.

Answer:

Step-by-step explanation:

A security is a financial instrument, generally any financial asset that can be traded. The nature of what is and is not considered a security generally depends on the jurisdiction in which the asset is traded. Securities are transferable financial instruments issued by companies or governments that convey ownership, debt obligations, or the right to buy, sell, or trade options.

It may represent a company represented by an ownership interest in the company in the form of shares, a creditor relationship with a government agency, or an ownership interest in the bonds of that agency or property rights represented by options.

Debt or fixed income securities represent loans that must be repaid on terms that indicate the amount borrowed, interest rate, and maturity date. In other words, a debenture is an instrument of debt such as a bond or a certificate of deposit (CD) that can be traded between parties. Debt securities, such as bonds and certificates of deposit, typically require the owner to make periodic interest payments, repay principal, and other contractual rights. Such securities are typically issued for a period of time and eventually repaid by the issuer.

Random sampling is a method of selecting a sample of items from a population in which the probabilities of selecting each item are the same.

Random sampling is used to ensure that each item in the population has an equal opportunity to be selected in the sample.

In this scenario, a random sample of size 40 is needed from a population of 200 items. The random start of 4 will be used to begin the sample selection process.

To begin, a list of all the items in the population should be created. Then, a random number generator can be used to select the first item in the sample, based on the random start of 4.

The next item in the sample should be selected at random from the remaining items in the population, and so on until the desired sample of 40 items is obtained.

Random sampling is an important method for ensuring that a sample is representative of the population it is drawn from.

This method helps to eliminate bias from the sample selection process and ensures that the sample accurately reflects the characteristics of the population.

Random sampling is used in many areas of research, including surveys, data collection, and experiments.
