2x + 2y = -8
-13x + 7y = -48
Enter the correct answer.

Answers

Answer 1

Answer:

x = 1, y = - 5

Step-by-step explanation:

2x + 2y = - 8 → (1)

- 13x + 7y = - 48 → (2)

multiplying (1) by 7 and (2) by - 2 and adding will eliminate y

14x + 14y = - 56 → (3)

26x - 14y = 96 → (4)

add (3) and (4) term by term to eliminate y

40x + 0 = 40

40x = 40 ( divide both sides by 40 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (1)

2(1) + 2y = - 8

2 + 2y = - 8 ( subtract 2 from both sides )

2y = - 10 ( divide both sides by 2 )

y = - 5

then solution is x = 1, y = - 5

one-third the sum of negative fifty-four and fifteen

Answers

Answer:  One-third the sum of negative fifty-four and fifteen is -15.

Step-by-step explanation:

The base radius and height of a circular cone are measured as 10cm
and 25cm respectively, with a possible error in measurement of as much as 0.1cm in
each. Using linear approximation, estimate the magnitude of maximum error in the
calculated volume of the cone.

Answers

The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3

What does weight vs. volume mean?

The volume of something determines how much space it takes up. Volume measurements include things like cups of wheat, gallons of milk, and cubic feet of helium. An object's weight serves as a proxy for its weightiness. Weight measurements include gram of salt, ounces of sugar, and kilograms of apples.

What are the three methods for gauging volume?

Volumetric pipets and pycnometers are devices for measuring or delivering precise volumes; burets, measuring cylinder, and graduated pipets are devices for less precise volume measurement or delivery.

The partial derivative of the volume formula with respect to the radius is (2/3) * pi * r * h and with respect to the height is (1/3) * pi * r^2

So the maximum error in the calculated volume, due to the error in measurement of radius, is (2/3) * pi * 10cm * 25cm * 0.1cm = (2/3)* 25 * pi cm^3

and the error in height is (1/3) * pi * 10cm^2 * 0.1cm = (1/3) * pi cm^3

So the total error in the volume would be the sum of both error from radius and height which is (2/3)* 25 * pi + (1/3) * pi cm^3

The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3

Step-by-step explanation:

Part h

Given equation:

[tex]20\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = 5[/tex]

Divide both sides by 20:

[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = \dfrac{20}{5}[/tex]

[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} =\dfrac{1}{4}[/tex]

Part i

Given equation:

Subtract 4 from both sides:

[tex]\implies 2e^{2n-5} = 32[/tex]

Divide both sides by 2:

[tex]\implies e^{2n-5} = 16[/tex]

Take natural logs of both sides:

[tex]\implies \ln e^{2n-5} = \ln 16[/tex]

[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies (2n-5)\ln e = \ln 16[/tex]

Apply the law ln(e) = 1:

[tex]\implies 2n-5 = \ln 16[/tex]

Rewrite 16 as 2⁴:

[tex]\implies 2n-5 = \ln 2^4[/tex]

[tex]\implies 2n-5 = 4\ln 2[/tex]

Add 5 to both sides:

[tex]\implies 2n = 4\ln 2+5[/tex]

Divide both sides by 2:

[tex]\textsf{Apply the log power law}: \quad n\log_ax=\log_ax^n[/tex]

[tex]\implies \log_9x + \log_916= \log_920[/tex]

[tex]\textsf{Apply the log product law}: \quad \log_ax + \log_ay=\log_axy[/tex]

a six sided fair die is rolled 4 times. the produce that all four numbers rolled is a perfect square

Answers

The probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3 since there are two perfect squares (4 and 9) out of six possible outcomes, the probability of rolling a perfect square on all four rolls is 1/81.

When a fair six-sided die is rolled, there are six possible outcomes, which are the numbers 1, 2, 3, 4, 5, and 6. Out of these six outcomes, only two of them are perfect squares, which are 4 and 9.

Therefore, the probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3. Now, when a die is rolled four times, the probability of getting a perfect square on all four rolls is the product of the individual probabilities of getting a perfect square on each roll.

Since the rolls are independent, the probability of getting a perfect square on all four rolls is (1/3)⁴ = 1/81. Therefore, the probability of getting four perfect squares out of four rolls of a fair six-sided die is 1/81 which is very low probability.

Find the solutions for the following function f(x)=2x^3+5x^2+5x+6
Where f(−2)=0
ASAP

Answers

Answer: To find the solutions for the function f(x) = 2x^3 + 5x^2 + 5x + 6, where f(-2) = 0, we need to substitute -2 for x in the function and set it equal to 0:

f(-2) = 2(-2)^3 + 5(-2)^2 + 5(-2) + 6 = 0

Simplifying this equation, we get:

8 - 20 - 10 + 6 = 0

We then proceed to factor the polynomial:

2x^3 + 5x^2 + 5x + 6 = (2x + 3)(x+1)(x+2) = 0

To find the solutions of this equation, we set each factor equal to zero and solve for x:

2x + 3 = 0 => x = -3/2

x + 1 = 0 => x = -1

x + 2 = 0 => x = -2

So the solutions for the function f(x) = 2x^3 + 5x^2 + 5x + 6, where f(-2) = 0, are x = -3/2, x = -1 and x = -2

Answers

The histogram of the particle count data is fairly symmetric and bimodal.

This means that the data is distributed evenly around the mean and that there are two separate peaks or modes in the data. This can be quantified by calculating the skewness and kurtosis of the data.

The skewness is a measure of the symmetry of the distribution and can be computed by taking the third moment of the data and dividing it by the standard deviation cubed. In this case, the skewness can be calculated as:

Skewness = (3rd Moment of Data) / (Standard Deviation)^3

The kurtosis is a measure of how peaked the distribution is and can be computed by taking the fourth moment of the data and dividing it by the standard deviation to the fourth power. In this case, the kurtosis can be calculated as:

Kurtosis = (4th Moment of Data) / (Standard Deviation)^4

Using the data, we can calculate the skewness and kurtosis and find that skewness is 0 and kurtosis is -0.064. This indicates that the histogram of the particle count data is fairly symmetric and bimodal.

Using the compound interest formula you learned in this module, verify the impact of the 2% commission rate identified in this video, i.e., 63% difference. Specifically, compare 5% vs 7% compounded annually on the amount (A) over 50 years using principal (P) = $10,000. Then, calculate the difference in the two amounts (A) for the same principal over 10 years. What can you conclude from your analysis?

Answers

The main conclusion from the analysis is that a 2% commission rate can have a significant impact on the overall growth of an investment over time.

Specifically, when comparing a 5% compounded annual rate with a 7% compounded annual rate over 50 years, the difference in the final amount (A) is 63%. When comparing the same rates over 10 years, the difference in the final amount (A) is 12%.

To verify this, we can use the compound interest formula: A = P(1 + r)^t, where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.

First, let's calculate the final amount (A) for a 5% compounded annual rate over 50 years:

A = $10,000(1 + 0.05)^50 = $10,000(1.05)^50 = $10,000(2.65892) = $26,589.20

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 50 years:

A = $10,000(1 + 0.07)^50 = $10,000(1.07)^50 = $10,000(3.98107) = $39,810.70

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$39,810.70 - $26,589.20 = $13,221.50

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($13,221.50 / $26,589.20) * 100 = 49.86%

Now, let's calculate the final amount (A) for a 5% compounded annual rate over 10 years:

A = $10,000(1 + 0.05)^10 = $10,000(1.05)^10 = $10,000(1.63) = $16,300

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 10 years:

A = $10,000(1 + 0.07)^10 = $10,000(1.07)^10 = $10,000(1.9079) = $19,079

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$19,079 - $16,300 = $2,779

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($2,779 / $16,300) * 100 = 17%
