In conclusion for part A  it would take T - 32.5 minutes to cook a 1.5 kg joint. For part B w is given by the formula w = (T - 25) / (-35). For part C 6.6 kg of beef needs to be cooked for 207 minutes. For part D  5.91 kg of beef needs to be cooked for 3 hours and 48 minutes.

How to solve?

a) To find how long it would take to cook a 1.5 kg joint, we can substitute w = 1.5 into the formula:

T - 35w + 25 = T - 35(1.5) + 25 = T - 32.5

So, it would take T - 32.5 minutes to cook a 1.5 kg joint.

b) To make w the subject of the formula, we need to isolate w on one side of the equation. We can start by subtracting 25 from both sides:

T - 35w = T - 25

Next, we can divide both sides by -35:

w = (T - 25) / (-35)

Therefore, w is given by the formula w = (T - 25) / (-35).

c) To find the weight of beef that needs to be cooked for 207 minutes, we can substitute T = 207 into the original formula:

T - 35w + 25 = 207

Simplifying this equation, we get:

-35w = -232

Dividing both sides by -35, we get:

w = 6.6 kg

Therefore, 6.6 kg of beef needs to be cooked for 207 minutes.

d) To find the weight of beef that needs to be cooked for 3 hours and 48 minutes (which is equivalent to 3 × 60 + 48 = 228 minutes), we can substitute T = 228 into the original formula:

T - 35w + 25 = 228

Simplifying this equation, we get:

-35w = -207

Dividing both sides by -35, we get:

w = 5.91 kg

Therefore, 5.91 kg of beef needs to be cooked for 3 hours and 48 minutes.

Step-by-step explanation:

Answer: C. $5166,667

Step-by-step explanation:

AI-generated answer

Let's begin with calculating the total amount saved over 15 years. The savings decrease by 3% every year from $25,000 in year 1. To calculate this, we can use the geometric series formula:

S = a(1 - r^n) / (1 - r)

Where S is the sum of the geometric series, a is the first term, r is the common ratio, and n is the number of terms.

In this case, a = 25000, r = 0.97 (since the savings decrease by 3% every year), and n = 15.

S = 25000(1 - 0.97^15) / (1 - 0.97)

S = $267,929.90

Next, we need to calculate the total amount at the end of year 15 with a 120% interest rate per year. We can use the compound interest formula:

A = P(1 + r/n)^(nt)

Where A is the total amount, P is the principal (in this case, $267,929.90), r is the interest rate (in decimal form), n is the number of times the interest is compounded per year (in this case, 1 since it's compounded annually), and t is the number of years (in this case, 15).

r = 120% = 1.2

A = 267929.90(1 + 1.2/1)^(1*15)

A = $5,166,667.00

Therefore, the closest option is C. $5,166,667.

When calculating a multiplicative seasonal index, the trend and seasonal factor are related using the multiplication operator.

The multiplicative seasonal index is a statistical technique used to decompose time series data into seasonal and trend components. When calculating the multiplicative seasonal index, the trend and seasonal factor are related using the multiplication operator.

The multiplication operator is used to combine the trend and seasonal components in the formula for the multiplicative seasonal index. This is because the trend and seasonal factors are not additive, but instead interact multiplicatively to produce the overall pattern observed in the time series data.

The formula for calculating the multiplicative seasonal index involves dividing the actual value by the trend estimate to remove the trend component, and then multiplying by the inverse of the average of seasonal indices for that period to isolate the seasonal component. By using the multiplication operator, we can account for both the trend and seasonal components in the time series data and accurately predict future values.

The objective function that has the same slope (parallel) as the given function $4x + 2y = 20 is

option d. $2x + $4y = $20.

To determine which objective function has the same slope as $4x + 2y = 20, we need to rearrange the given equation into slope-intercept form, y = mx + b, where m represents the slope. In this case, we have:

$4x + $2y = $20

$2y = -$4x + $20

y = -2x + 10.

By comparing this equation with the slope-intercept form, we can see that the slope is -2. Therefore, we need to find the objective function with the same slope. Among the options, option d, $2x + $4y = $20, has a slope of -2 since its coefficient of x is 2 and its coefficient of y is 4 (2/4 simplifies to -1/2, which is the same as -2/1). Thus, option d is the correct answer.

The dP/dt of the adiabatic expansion is -42/11 kPa/min

An adiabatic process is a process in which there is no exchange of heat from the system to its surrounding neither during expansion nor during compression

Given b=1.5, P=7 kPa, V=110 cm³, and dV/dt=40 cm³/min

PVᵇ = C

Taking logs of both sides gives:

ln P + b ln V = ln C

Taking partial derivatives gives:

\(\frac{1}{P}\frac{∂P}{∂t} + \frac{b}{V}\frac{∂V}{∂t} = 0\)

Substitutituting the values b, P, V and dV/dt into the derivative above:

1/7 x dP/dt +  1.5/110 x 40 = 0

1/7 x dP/dt +  6/11 = 0

1/7 x dP/dt = - 6/11

The correct answer is option d. The theoretical Probability of spinning a multiple of 3 with one spin is 0.

The theoretical probability of an event, we need to identify the number of favorable outcomes (the desired event) and the total number of possible outcomes.

In this case, the event is spinning a multiple of 3 on the spinner. Let's examine the possible outcomes and identify the favorable outcomes:

Possible outcomes on the spinner: {1, 2, 3, 4, 5, 6}

Favorable outcomes (multiples of 3): {3, 6}

The total number of possible outcomes is 6, and the number of favorable outcomes is 2.

The theoretical probability of spinning a multiple of 3 can be calculated as:

P(multiple of 3) = (Number of favorable outcomes) / (Total number of possible outcomes)

P(multiple of 3) = 2 / 6

Answer:

Minimum

Need to know:

Derivative power rule: d/dx xⁿ = nxⁿ⁻¹

Derivative constant rule: d/dx c = 0

Step-by-step explanation:

A way to determine whether the quadratic equation has a maximum or a minimum is by graphing it.

If we look at the image below, we notice that the graph does not go to the bottom infinitely, but it keeps going up infinitely. This means there is a minimum to this graph.

Another way to determine this is through calculus.

First, we have to find the point of extremum

Find the derivative of the given equation

d/dx 4x² -  3x - 43

You can separate the terms and solve them individually

d/dx 4x² = 4(2)(x²⁻¹) = 8x

d/dx -3x = -3(1)(x¹⁻¹) = -3(1)(1) = -3

d/dx -43 = 0

y' = 8x - 3

Set y' to equal 0

8x - 3 = 0

Add 3 to both sides

8x - 3 = 0

    + 3   + 3

8x = 3

Divide both sides by 8

8x/8 = 3/8

x = 3/8

There is only one point of extremum

Now we have to test whether the equation changes from negative to positive or positive to negative

If it changes from negative to positive, that point is a minimum

If it changes from positive to negative, that point is a maximum

To find this, pick a number less than 3/8 and plug it in the place of x in the derivative equation. We'll use 0.

y' = 8(0) - 3 = -3

Now we will do the same for a number larger than 3/8. We'll use 1

y' = 8(1) - 3 = 5

Since the lesser side of 3/8 is negative and the larger side of 3/8 is positive, that means it changes from negative to positive. This point is a minimum.

Approximately 15,418.646 cubic feet of rice are in the silo when it is 34% full.

To calculate the approximate volume of rice in the silo when it is 34% full, we need to find the volume of a cylindrical segment.

First, let's calculate the height of the rice-filled portion. If the silo is 40 feet tall and it is 34% full, the height of the rice-filled portion is 34% of 40 feet, which is 0.34 * 40 = 13.6 feet.

Now, let's calculate the radius of the rice-filled portion. The diameter of the silo is 16 feet, so the radius is half of the diameter, which is 16 / 2 = 8 feet.

Using the formula for the volume of a cylindrical segment:

V = (1/3) * π * h * (3r^2 + h^2)

where V is the volume, π is approximately 3.14159, h is the height of the rice-filled portion, and r is the radius of the rice-filled portion.

Plugging in the values:

V = (1/3) * 3.14159 * 13.6 * (3 * 8^2 + 13.6^2)

Calculating this expression gives us:

V ≈ 3.14159 * 13.6 * (3 * 64 + 184.96)

≈ 3.14159 * 13.6 * (192 + 184.96)

≈ 3.14159 * 13.6 * 376.96

≈ 15418.646 cubic feet

Therefore, approximately 15,418.646 cubic feet of rice are in the silo when it is 34% full.
