No, molar mass is a constant and does not depend on pressure or temperature.

Molar mass is a physical property of a substance and is the mass of one mole of a given substance. It is a constant value that represents the amount of grams of a substance that contains 022 x 1023 atoms or molecules. Since molar mass is a constant, it does not depend on pressure or temperature. Pressure and temperature can affect the physical and chemical properties of a substance, but they do not have an effect on the molar mass. The molar mass of a substance can be useful in determining molecular and empirical formulas, as well as calculating densities and molar concentrations.

Step-by-step explanation:

First, find 5/8 of 48

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:

48

1

So now that we've converted 48 into a fraction, to work out the answer, we put the fraction 5/8 side by side with our new fraction, 48/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

5 x 48/8 x 1 = 240/8

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 240 and 8 is 8.

We can now divide both the new numerator and the denominator by 8 to simplify this fraction down to its lowest terms.

240/8 = 30

8/8 = 1

When we put that together, we can see that our complete answer is:

30/1

The complete and simplified answer to the question what is 5/8 of 48 is:

Now that we have found 5/8 of 48. It can be confirmed that Sue gave her sister 30 dolls.

Answer:

|h - 1.6| ≤ 0.2

Step-by-step explanation:

Given:

1.4≤ h ≤ 1.8

To write the compound inequality as an absolute value inequality, follow the following steps:

(i) Find the mid-point between the given extremes of the inequality.

The given extremes are 1.4 and 1.8

The mid-point is therefore, (\(\frac{1.4 + 1.8}{2}\)) = 1.6

(ii) With the mid-point value calculated in (i) above, form the inequality around that by subtracting 1.6 from each term in the given compound inequality. i.e

1.4 - 1.6 ≤ h - 1.6 ≤ 1.8 - 1.6

(iii) Solve the result from (ii) above.

-0.2 ≤ h - 1.6 ≤ 0.2

(iv) Re-write the result from (iii) above in absolute value inequality. i.e

-0.2 ≤ h - 1.6 ≤ 0.2 becomes

|h - 1.6| ≤ 0.2

Therefore, the absolute value inequality of the given compound inequality is |h - 1.6| ≤ 0.2

Answer:

so your answer is below

x=1/2

To estimate the absolute error in approximating tan(0.25) using the 2nd-order Taylor polynomial centered at 0, we need the remainder term expression.

In Taylor series approximation, the remainder term represents the difference between the actual value of a function and its approximation using a truncated Taylor polynomial. It helps estimate the absolute error of the approximation.

The remainder term for the 2nd-order Taylor polynomial centered at 0 is given by the formula: Rn(x) = f'''(c) * (x - a)^n / (n+1)!, where f'''(c) represents the third derivative of the function at some point c between 0 and 0.25.

To estimate the absolute error in approximating tan(0.25) using the 2nd-order Taylor polynomial, we need the value of the third derivative of the tangent function and the point c between 0 and 0.25 at which we evaluate it. Without this information, we cannot calculate the exact value of the remaining term or the absolute error.

To obtain an estimate of the absolute error, we would need to evaluate the remainder term at a specific value of c and substitute it into the expression. Without the given value of c or the third derivative of the tangent function, we cannot provide a numerical estimation of the absolute error in this case.

Answer:

10000

Step-by-step explanation:

Answer:

1,000

Step-by-step explanation:

thx so much for the free points ur actions are and will be appriciated.

Answer:

a).

\( \sin(2x) = \frac{1}{2 \sqrt{2} } \\ \\ 2x = { \sin }^{ - 1} ( \frac{1}{2 \sqrt{2} } ) \\ \\ 2x = 45 \degree\)

since sine is in the 2nd quadrant, other angle = 180° - x:

\(2x = 45 \degree, \: 135 \degree\)

we must make two rotations since it's a double angle:

\(2x = 45 \degree, \: 135\degree, \: 225\degree, \: 315\degree, \: 495\degree, \: 675\degree \\ \)

divide each angle by 2:

\(x = 22.5\degree, \: 67.5\degree, \: 112.5\degree, \: 157.5\degree, \: 247.5\degree, \: 337.5\degree \\ \)

Answer = {x: x = 22.5°, 67.5°, 112.5°, 157.5°, 247.5, 337.5°}

b).

\( \sin(3z) = - 0.42 \\ 3z = { \sin }^{ - 1} ( - 0.42) \)

since ans is negative, we take the quadrants of cosine and tangent:

\(3z = 204.8\degree, \: 335.2\degree \)

we make three rotations:

\(3z = 384.8\degree, \: 515.2\degree, \: 695.2\degree, \: 875.2\degree, \: 1055.2\degree, \\ \)

answer is {z : z = 128.3°, 171.7°, 231.7°, 291.7°, 351.7°}

Answer:

y = -2x - 6  

Step-by-step explanation:

Use slope-intercept form to start the equation. y2 - y1 / x2 -x1

-6 - 0 / 0 - (-3) = -6 / 3 = m = -2

Then plug m (-2) into your y=mx+b equation.

y = -2x + b

substitute -6 for y value and 0 for x value to find value of b.

-6 = -2(0) + b

simplify

-6 = 0 +b

subtract 0 from both sides

-6 = b

plug b value back into the equation

final equation of line is: y = -2x -6

Answer:

200%

Step-by-step explanation:

if you substitute in numbers you'll find this as the answer.

as an example:

suppose the sides of the rectangle was 1 unit long.

area before change: 1 * 1 = 1

then, the length gets increase by 50% making it 1.5 ( 50% of 1 is 0.5, then you add it onto 1, 1 + 0.5 = 1.5 )

the width gets increased by 100% making it 2 ( 1 + 1 = 2 )

new area: 1.5 * 2 = 3

1 increased by 200% is 3, therefore the answer is 200%

The value of x for which the matrix does not have an inverse is x = -4, option (B). For all other values of x (x ≠ -4), the matrix will have an inverse.

To determine the value of x for which a 2x2 matrix 2 -2 4 x does not have an inverse, we need to consider the determinant of the matrix.

The determinant of a 2x2 matrix is calculated by multiplying the values on the main diagonal and subtracting the product of the values on the off-diagonal. For the given matrix, the determinant is:

Determinant = (2 * x) - (-2 * 4) = 2x + 8

For a matrix to have an inverse, the determinant must not be equal to zero.

Therefore, we need to find the value of x that makes the determinant zero:

2x + 8 = 0

2x = -8

x = -4

Answer & Step-by-step explanation:

(5√2 - 4√3)(5√2 - 4√3)

We can rewrite this equation into a more simpler form.

(5√2 - 4√3)²

Now, we multiply. When multiplying, its important we multiply each term instead of combining them together.

When you multiply a radical by itself, then the base number will be by itself as the product.

So......

(5)² = 25

(4)² = 16

(√2)² = 2

(√3)² = 3

So, now the equation looks like this..

(25 * 2) + (16 * 3)

Multiply the terms.

50 + 48

Add the numbers.

50 + 48 = 98

So, your answer will be answer choice D. The radical in choice D represents the radicals that are in the problem multiplied together.

Step-by-step explanation:

The concentrations of the other three tubes are 1500 ng/ml, 15000 ng/ml, and 150000 ng/ml, respectively.

In order to answer the question, we need to have more information about the dilution factor of the tubes. Assuming that all the tubes have the same dilution factor, we can use the formula:C1V1 = C2V2

Where,C1 = concentration of the initial solution,V1 = volume of the initial solution,C2 = concentration of the final solution,V2 = volume of the final solution

Given that the concentration of the first tube is 150 ng/ml, we can use the above formula to calculate the concentrations of the other three tubes, provided we know the dilution factor.

Let's assume that the dilution factor is 10, which means that the initial volume was diluted by a factor of 10 to obtain the final volume in each tube.

Using the formula,C1V1 = C2V2

For tube 1, C1 = 150 ng/ml, V1 = 1 ml (assuming initial volume is 1 ml), C2 = concentration of tube 2, V2 = 0.1 ml (assuming a dilution factor of 10)

Substituting the values,150 x 1 = C2 x 0.1C2 = 1500 ng/ml

Therefore, the concentration of tube 2 is 1500 ng/ml.

Repeating the same process for the other two tubes, we get:C3 = 15000 ng/mlC4 = 150000 ng/ml

The probability that her third child would be a girl is 50%.

Probability:

In math probability means the possible of happening a particular event amount the total number of event.

Given,

Here we need to find if a woman's first child is a girl and her second child is also a girl, what is the probability that her third child would be a girl.

We already know that, there are two sex chromosomes X and Y.

And in the humans are diploid having two sex chromosomes, in females a pair of the X chromosome is found while in males an X and Y chromosome is present.

So, there is  50% chance that the subsequent child is going to be a girl because it entirely depends upon the chromosome of the sperm which fertilizes the ovum.

For each pregnancy features a  50% chance of leading to a boy or girl and this doesn't include the likelihood of multiples.

Here already having 2 girls previously doesn't affect the probabilities of any resulting pregnancy.

Therefore, the prospect of getting a girl remains at  50%.

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.

7. Review and refine: Step back and review the graph to ensure accuracy and clarity. Make any necessary adjustments to the graph to improve its presentation.

When you take a look at the first image, you will see that

Throughot the graph, the distance increases as the time increases, and we can see a rapid in the distance

So the first graph matches with table B

As for the second graph, when you take a look at it

you will see that the distance increases with time initially, but after a while the distance decreases with time

so table A best descibe the second graph

Hence the second graph matches with table A

Finally, the third graph, taking a closer look at the third graph, you will see that the distance also increases with time, but not a rapid increase

so the table C best discribe the third graph

Hence the third graph matches table C
