Answer:

Step-by-step explanation:

Let w and d represent the costs of white chocolate chip cookie dough and double chocolate chip cookie dough, respectively.

  6w +12d = 204 . . . . . . Ryan's sale

  7w +7d = 147 . . . . . . . . Cody's sale

We can divide out the common factor to put these equations into standard form:

  w +2d = 34

  w +d = 21

Subtracting the second of these equations from the first, we get ...

  (w +2d) -(w +d) = (34) -(21)

  d = 13

Using the second equation, we can find w:

  w = 21 -d = 21 -13 = 8

The costs of the chocolate chip cookie dough packages are ...

  white: $8

  double: $13

A prism is a three-dimensional shape with two identical ends, called bases, and sides that are all parallelograms. The sides may be squares, rectangles, or other shapes. A prism is a solid geometric shape with two faces that are parallel and the same size and shape.

A trapezium is a four-sided shape with two parallel sides, called the bases, and two non-parallel sides, called the legs. The two non-parallel sides can be of different lengths, and the angles between them can be different as well.

In the given question,

Length of rectangular prism = 12 m

Breadth of rectangular prism = 10 m

Height of rectangular prism = 2.4 m

Volume of rectangular prism = L × B × H

Volume of rectangular prism = 12 × 10 × 2.4 = 288 m³

Area of trapezium base = 245 \(m^{2}\)

Area of trapezium base = 1/2 × (8 + 8.2) × 0.6

Area of trapezium base = 4.86 m²

Volume of trapezoidal prism = Area × Height between trapezium ends

Volume of trapezoidal prism = 4.86 × 10 = 48.6 m³

Total volume of water = 288 + 48.6 = 336.6 m³

Step-by-step explanation:

SUV was detected exceeding the posted speed limit of 60 km/hr, 40 kilometers would she have traveled if she was driving 80 km/hr for half an hour.

Given that an SUV was detected exceeding the posted speed limit of 60 km/hr. We need to calculate how many kilometers would she have traveled if she was driving 80 km/hr for half an hour.

Using the formula,

s = v.t

Where s = Distance

           v = Velocity

            t = time

In this scenario, the velocity of the SUV is given as 80 km/hrt = 0.5 hrs

The distance she will travel at 80 km/hr in 0.5 hrs will be; s = 80 x 0.5s = 40 km

Therefore, the SUV would have traveled 40 kilometers if she was driving 80 km/hr for half an hour.

To graph a piecewise function, plot the different parts of the function separately based on the specified conditions or intervals, and ensure continuity at the endpoints.

Here's a step-by-step guide on how to graph a piecewise function:

1. Identify the different conditions or intervals: A piecewise function is defined by different equations or expressions for specific intervals or conditions. Identify these conditions or intervals and the corresponding equations for each interval.

2. Plot the intervals on the x-axis: Identify the range of values for the x-axis based on the given intervals. Mark the intervals on the x-axis accordingly.

3. Graph each part of the function: For each interval, graph the corresponding equation or expression. Treat each part as a separate function within its defined interval.

4. Consider the endpoints of each interval: Pay attention to the endpoints of each interval and determine whether they are included or excluded from the graph. Use open or closed circles to represent the endpoints, depending on whether they are included or excluded.

5. Ensure continuity: Check if the function is continuous across the intervals. Make sure there are no gaps or jumps in the graph where the intervals meet.

6. Label the axes and add any necessary annotations: Label the x-axis and y-axis, and add any necessary annotations such as the function name, equation, or any important points or features.

Probability samples have the advantage of providing a more representative sample of the population over non-probability samples.

Each member of the population has a known and non-zero chance of being chosen for the sample in probability sampling. This means that every member of the population has an equal chance of being chosen, which aids in reducing selection bias.

As a result, probability samples are more likely to accurately reflect population characteristics and can provide more reliable and valid population inferences.

Non-probability samples, on the other hand, lack this property and may not accurately reflect the population. In a convenience sample, for example, people are chosen simply because they are easily accessible, which may not accurately reflect the population as a whole.

Step-by-step explanation:

The value of the rate of change when we put a glass of water at room temperature is 1/3.

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another.

The connection defining how one quantity changes in response to the change in another quantity is given by the rate of change formula. The formula for calculating the rate of change from y coordinates to x coordinates is y/x = (y2 - y1)/. (x2 - x1 ).

Rate of change  = change in temperature / time

= 10-5/15

=5 / 15

= 1/3

To convert a system of differential equations, we differentiate the second equation with respect to the independent variable and substitute for the derivative of the first equation.

Consider a system of differential equations in the form:

\(\frac{dx}{dt}\) = f(t)

\(\frac{dy}{dt}\) = g(t)

To convert this system into a second-order differential equation, we differentiate the second equation with respect to t:

\(\frac{d^{2} y}{dt^{2} }\) = g'(t)

Next, we substitute for \(\frac{dy}{dt}\) from the first equation:

\(\frac{d^{2} y}{dt^{2} }\)  = g'(t) = g'(x)

We now have a second-order differential equation in terms of x. By solving this equation, we can find the second derivative of y as a function of x.

To calculate the values of x at which certain conditions are satisfied, such as y = 0 and \(\frac{dy}{dt}\) = 0, we need additional information or initial/boundary conditions. Without specific conditions, it is not possible to find the exact values of x that satisfy these conditions.

Therefore, without further information, we cannot determine the specific values of x and y that satisfy the conditions y = 0 and \(\frac{dy}{dt}\) = 0. Additional conditions or information are necessary to obtain specific values.

Answer:

-2.41

Step-by-step explanation:

rearrange:

12x + 10 + 5x + 31

Or

12x + 5x + 10 + 31

Simplify and set that is = to zero so we can isolate x

17x + 41 = 0

To solve for x, we can isolate x on one side of the equation by subtracting 41 from both sides:

17x = -41

Finally, we can solve for x by dividing both sides by 17:

x = -41/17

therefore, x is equal to approximately -2.41 when we plug it back into the original equation:

12x + 10 + 5x + 31 = 0

12(-2.41) + 10 + 5(-2.41) + 31 = 0

-28.92 + 10 - 12.05 + 31 = 0

0 (which is true)

Step-by-step explanation:

We have given a linear transformation T: R³→R². We have to find the standard matrix A and use it to find T(2,-3,1). The two linearly independent columns of the standard matrix will be images of standard basis vectors of R³ under the linear transformation T. The given linear transformation is:T(x, y, z) = (5x + y - 2z, 7x + 2y) = x(5, 7) + y(1, 2) + z(-2, 0)Now, the standard matrix of this linear transformation A is given by A = [T(e₁), T(e₂), T(e₃)], where e₁, e₂, e₃ are standard basis vectors of R³.So, A = [T(1,0,0), T(0,1,0), T(0,0,1)] = [T(e₁), T(e₂), T(e₃)]Using the given transformation, we haveT(1,0,0) = (5, 7)T(0,1,0) = (1, 2)T(0,0,1) = (-2, 0)Therefore, A = [T(1,0,0), T(0,1,0), T(0,0,1)] = [5, 1, -2; 7, 2, 0]Hence, the standard matrix A is A = [5, 1, -2; 7, 2, 0]. Now, using this matrix, we can find T(2,-3,1) as:T(2,-3,1) = A [2, -3, 1]T(2,-3,1) = [5, 1, -2; 7, 2, 0] [2, -3, 1]T(2,-3,1) = [(5x2) + (1x-3) + (-2x1), (7x2) + (2x-3) + (0x1)]T(2,-3,1) = [7, 11]Therefore, T(2,-3,1) = (7, 11). Conclusion:We have found the standard matrix A for the linear transformation T: R³→R² and used it to find T(2,-3,1). The standard matrix A is A = [5, 1, -2; 7, 2, 0] and T(2,-3,1) = (7, 11). The main answer is as follows: A = [5, 1, -2; 7, 2, 0]T(2,-3,1) = (7, 11)The answer is more than 100 words.

The value of standard matrix is,

A = [5, 1, -2; 7, 2, 0]

We have given,

A linear transformation T: R³→R².

We have to find the standard matrix A and use it to find T(2,-3,1).

The two linearly independent columns of the standard matrix will be images of standard basis vectors of R³ under the linear transformation T.

The given linear transformation is:

T(x, y, z) = (5x + y - 2z, 7x + 2y)

             = x(5, 7) + y(1, 2) + z(-2, 0)

Now, the standard matrix of this linear transformation A is given by,

A = [T(e₁), T(e₂), T(e₃)],

where e₁, e₂, e₃ are standard basis vectors of R³.

So, A = [T(1,0,0), T(0,1,0), T(0,0,1)]

A = [T(e₁), T(e₂), T(e₃)]

By Using the given transformation, we have;

T(1,0,0) = (5, 7)T(0,1,0)

           = (1, 2)T(0,0,1)

            = (-2, 0)

Therefore, A = [T(1,0,0), T(0,1,0), T(0,0,1)] = [5, 1, -2; 7, 2, 0]

Hence, the standard matrix A is,

A = [5, 1, -2; 7, 2, 0].

Now, using this matrix, we can find T(2,-3,1) as:

T(2,-3,1) = A [2, -3, 1]

T(2,-3,1 = [5, 1, -2; 7, 2, 0] [2, -3, 1]

T(2,-3,1) = [(5x2) + (1x-3) + (-2x1), (7x2) + (2x-3) + (0x1)]

T(2,-3,1) = [7, 11]

Therefore, T(2,-3,1) = (7, 11).

Hence, We found the standard matrix A for the linear transformation T: R³→R² and used it to find T(2,-3,1). The standard matrix A is,

A = [5, 1, -2; 7, 2, 0]

and T(2,-3,1) = (7, 11).

Answer:

Se pueden obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad de 5 kg del medicamento

Step-by-step explanation:

La cantidad en masa de paracetamol en una tableta = 500 mg de paracetamol / tableta

El número de comprimidos que contienen 500 mg de paracetamol que se pueden obtener a partir de 5 kg del medicamento (paracetamol) se calcula dividiendo los 5 kg del medicamento por los 500 mg de paracetamol / comprimido de la siguiente manera;

\(El \ nmero \ de \ tableta = \dfrac{5 \ kg \ paracetamol}{500 \ mg \ paracetamol/tableta }\)

Observamos que 5 kg = 5,000,000 mg

Por lo tanto;

\(El \ numero \ de \ tableta = \dfrac{5,000,000 \ mg \ paracetamol}{500 \ mg \ paracetamol/tableta } = 10,000 \ tabletas\)

Por tanto, podemos obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad dada de 5 kg del medicamento.
