Answer:

  a) 22e^-0.01t kilograms

  b) about 19.906 kilograms

Step-by-step explanation:

You want an equation for the amount of salt in a 15 kL brine tank initially containing 22 kg of salt if 150 L/min of the contents is replaced by pure water.

The quantity of salt s(t) in kilograms can be described by the differential equation ...

  s(0) = 22; s'(t) = -150/15000·s(t)

The solution can be found by separation of variables.

  [tex]\displaystyle\dfrac{ds}{dt}=-0.01s\\\\\int{\dfrac{1}{s}}\,ds=-0.01\int{}\,dt\\\\\ln{s}=-0.01t+c_1\\\\s=c_2\cdot e^{-0.01t}\qquad\text{where $c_2$ is $s(0)=22$}\\\\\boxed{s(t)=22e^{-0.01t}}[/tex]

The amount of salt remaining after 10 minutes is ...

  s(10) = 22·e^(-0.01·10) = 22·e^-0.1

  s(10) ≈ 19.906 . . . . kilograms

There is about 19.906 kg of salt in the tank after 10 minutes.

__

Additional comment

The initial rate of change of the amount of salt is -22/100 kg/min, so after 10 minutes, we expect an approximate reduction by 2.2 kg to 19.8 kg. Since the rate slows as salt is removed, the value 19.9 kg after 10 minutes is reasonable.

There are a couple of places where the integration constant can be put in the equation for the salt quantity. As a multiplier of the exponential function, its value is found in a straightforward way.

Answer:

The polynomial expression x^4 + 4x - 21 cannot be factored into linear factors with rational coefficients. This can be shown using the rational root theorem, which states that any rational roots (zeros) of the polynomial must be of the form p/q, where p is a factor of the constant term (in this case, 21) and q is a factor of the leading coefficient (1). The only possible rational roots of this polynomial are ±1, ±3, ±7, and ±21. However, plugging in each of these values does not give a zero of the polynomial, meaning it has no rational roots. Therefore, it cannot be factored into linear factors with rational coefficients. It may still be factorable using complex numbers, but it is not factorable using only real numbers.

Answer:

Step-by-step explanation:

The mean absolute deviation (MAD) of the given set of data is 3.875.

To calculate the mean absolute deviation, we first need to find the mean of the data set by adding up all the numbers and dividing by the total number of values:

Mean = (12 + 10 + 12 + 6 + 8 + 4 + 2 + 12) / 8

Mean = 8

Next, we find the absolute deviation of each number from the mean. To do this, we subtract the mean from each number and take the absolute value:

|12 - 8| = 4

|10 - 8| = 2

|12 - 8| = 4

|6 - 8| = 2

|8 - 8| = 0

|4 - 8| = 4

|2 - 8| = 6

|12 - 8| = 4

Then, we find the mean of the absolute deviations:

Mean absolute deviation = (4 + 2 + 4 + 2 + 0 + 4 + 6 + 4) / 8

Mean absolute deviation = 26 / 8

Mean absolute deviation = 3.875

The Height of the toy box is 7 feet.

The height of the toy box in the shape of a rectangular prism is calculated using the following formula:

Volume = Length * Width * Height.

In this case, Volume = 36 cubic feet, Length = 2 * Width, and Height = Width - 1.
Therefore, we can solve for the Width by substituting the values into the formula:
36 = (2 * Width) * (Width - 1)
36 = 2 * Width^2 - Width
2 * Width^2 - Width - 36 = 0

By using the quadratic formula, Width = 8.
Therefore, the Height of the toy box is 7 feet.

The length of altitude CD is 133/25 units.

What is the length if altitude?

To find the length of altitude CD, we need to find the length of the line segment CD, which is perpendicular to AB and passes through the point C.

First, let's find the equation of the line AB. We can use the two-point form:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is one of the points on the line. Using points A and B, we get:

m = (0 - 6)/(8 - 0) = -3/4

y - 6 = (-3/4)(x - 0)

y = (-3/4)x + 6

Next, let's find the slope of the line CD, which is the negative reciprocal of the slope of AB. This is because perpendicular lines have slopes that are negative reciprocals of each other. Therefore:

m_CD = 4/3

Now we can use the point-slope form to find the equation of line CD. We know that the line passes through point C (5, 8), so:

y - 8 = (4/3)(x - 5)

Simplifying, we get:

y = (4/3)x - 4/3 + 8

y = (4/3)x + 20/3

Now we need to find the intersection of line CD with line AB. We can solve the system of equations:

y = (-3/4)x + 6

y = (4/3)x + 20/3

Setting the two expressions for y equal to each other, we get:

(-3/4)x + 6 = (4/3)x + 20/3

Multiplying both sides by 12, we get:

-9x + 72 = 16x + 80

25x = -8

x = -8/25

Substituting this value of x into either equation, we get:

y = (-3/4)(-8/25) + 6 = 57/25

Therefore, the point of intersection is (-8/25, 57/25).

Finally, we can use the distance formula to find the length of CD, which is the distance between C and the point of intersection:

d = √[(5 - (-8/25))² + (8 - 57/25)²]

d = √[(125/25 + 8/25)² + (200/25 - 57/25)²]

d = √[(133/25)² + (143/25)²]

d = √(17689/625)

d = 133/25

Rent-A-Reck Incorporated should charge $95 to maximize its revenue and the company will rent 45 cars at a price of $95.

To determine the price that will maximize Rent-A-Reck Incorporated's revenue, we need to consider the relationship between the price of renting a car and the number of cars that are rented.

Based on the information provided, we know that the demand for rental cars decreases as the price increases. Specifically, for each $5 increase in price, two fewer cars will be rented.

Let's denote the price of renting a car as P and the number of cars rented as Q. Then we can express the relationship between price and quantity as:

Q = 60 - 2(P - 80)/5

This equation tells us that as the price P increases, the number of cars rented Q decreases. We can also use this equation to find the price that will maximize revenue. Revenue is calculated by multiplying the price by the number of cars rented, so we can write the revenue function as:

R = P(Q) * Q

= P * (60 - 2(P - 80)/5)

To find the price that maximizes revenue, we need to find the value of P that makes R as large as possible. One way to do this is to take the derivative of R with respect to P and set it equal to zero:

dR/dP = (60 - 2(P - 80)/5) - 2P/5 = 0

Solving for P, we get:

P = $95

To find the number of cars that will be rented at this price, we can substitute P = $95 into the demand equation:
