Write in slope intercept form 6y+y=5

The function h(x) = |x - 2| + 5 is increasing for x values greater than 2. Mathematically, we can express this interval as (2, ∞).

So, the correct option is A. (2, ∞)

To determine on which interval the function h(x) = |x - 2| + 5 is increasing, we need to examine the behavior of the function as x increases.

First, let's analyze the absolute value function |x - 2|. The absolute value of a number is always non-negative, so |x - 2| is greater than or equal to zero for all values of x. Therefore, it does not affect the overall increasing or decreasing behavior of the function h(x).

Now, let's consider the term |x - 2| + 5. As x increases, the value of |x - 2| remains constant (as long as x is greater than or equal to 2), but the value of the entire expression |x - 2| + 5 increases. This is because we are adding a positive constant (5) to |x - 2|.

Therefore, the function h(x) = |x - 2| + 5 is increasing for x values greater than 2. Mathematically, we can express this interval as (2, ∞).

So, the correct option is A. (2, ∞)

Answer:

[tex](x - 3)^2 + (y + 2)^2 = 16[/tex]

Step-by-step explanation:

The equation of a circle with a center at (h, k) and radius r is given by:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

We are given that the points G(5,-2) and H(1, −2) lie on the circle. We can use the distance formula to find the distance between these two points.

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]d = \sqrt{(5 - 1)^2 + ((-2) - (-2))^2} = \sqrt{16} = 4[/tex]

Therefore, the radius of the circle is 4.

We can now find the center of the circle by taking the average of the x-coordinates and y-coordinates of the points G and H.

[tex](h, k) = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) = \left(\frac{5 + 1}{2}, \frac{-2 - 2}{2}\right) = (3, -2)[/tex]

Therefore, the equation of the circle is:

[tex](x - 3)^2 + (y + 2)^2 = 4^2[/tex]

Simplifying the equation, we get:

[tex]\bold{(x - 3)^2 + (y + 2)^2 = 16}[/tex] is a required equation.

To find the quotient when dividing the polynomial [tex]P(x) = 2x^3 + 5x^2 - 3x + 4[/tex] by the binomial (x - 2), we can use synthetic division. Synthetic division is a method used to divide polynomials quickly and efficiently.

First, we set up the synthetic division table by writing the coefficients of the polynomial in descending order:

    2  |   5   -3   4

        |___________

Next, we bring down the first coefficient, which is 5:

    2  |   5   -3   4

        |___________

        |   5

To calculate the next row, we multiply the divisor (2) by the value in the previous row (5) and write the result below the next coefficient:

    2  |   5   -3   4

        |___________

        |   5

        |___________

             10

We add the values in the second and third rows:

    2  |   5   -3   4

        |___________

        |   5

        |___________

            10    7

We repeat this process until we reach the last coefficient:

Answer: Let's try x = 1 as a potential solution:

Substituting x = 1 into the inequality:

3(1) - 7 ≥ -10

3 - 7 ≥ -10

-4 ≥ -10

Since -4 is greater than or equal to -10, x = 1 is a solution to the inequality.

Let's try x = -3 as a potential solution:

Substituting x = -3 into the inequality:

3(-3) - 7 ≥ -10

-16 ≥ -10

Since -16 is not greater than or equal to -10, x = -3 is not a solution to the inequality.

There is 90% confidence that the population standard deviation is between 5.094 weeks and 19.803 weeks.

The correct option is C.

To construct a confidence interval for the population standard deviation, we can use the chi-square distribution.

Given data:

Sample size (n) = 12

Sample standard deviation (s) = 9.904 weeks

The chi-square distribution is right-tailed and at 90% confidence level, the significance level is 0.1 on each tail.

Degrees of freedom (df) = n - 1

Degrees of freedom (df) = 12 - 1

Degrees of freedom (df) = 11

From the chi-square distribution table, the critical values for a 90% confidence level with 11 degrees of freedom are 3.816 and 22.362.

Therefore, the 90% confidence interval for the population standard deviation is:

Lower bound = √(n-1) * s² / χ² upper)

Lower bound = √(11 * 9.904²) / 22.362)

Lower bound = 5.094

Upper bound = √(n-1) * s² / χ² lower)

Upper bound = √(11 * 9.904²) / 3.816)

Upper bound = 19.803

To calculate the amount of money needed to deposit into the account today, we can use the concept of present value. The present value represents the current value of future cash flows, taking into account the time value of money.

1. To calculate the present value of the cash flows, we can use the formula for the present value of an annuity:

PV = C * (1 - (1 + r)^(-n)) / r

Where PV is the present value, C is the cash flow per period, r is the interest rate per period, and n is the number of periods.

In this case, the cash flow per period is $100, the interest rate per period is 6% (0.06), and the number of periods is 20.

Plugging in the values into the formula:

PV = 100 * (1 - (1 + 0.06)^(-20)) / 0.06

Calculating this value gives us the amount of money needed to deposit into the account today.

2. To show explicitly using an Excel spreadsheet, you can set up a column for each year, starting from year 0 (the present year) to year 20. In the first row, enter the initial deposit amount calculated in step 1. In the subsequent rows, use a formula to calculate the value for each year by adding the interest earned and subtracting the annual withdrawal of $100. The last value in year 20 should be zero, indicating that the account will have no remaining balance after the last withdrawal.

3. If the bank's annual interest rate changes to 10%, you would need to recalculate the present value using the new interest rate. Repeat step 1 with the new interest rate of 10% (0.10) to find the updated amount of money needed to deposit into the account today. Compare this value with the previous amount calculated with a 6% interest rate to determine the difference.

The remaining credit after 65 minutes of calls is approximately $15.45.

To find the remaining credit after 65 minutes of calls, we can use the given information to determine the linear function that relates the remaining credit to the total calling time.

Let's assume the total calling time in minutes is represented by the variable "x," and the remaining credit in dollars is represented by the variable "y."

We are given two data points:

When x = 43, y = $19.41.

When x = 56, y = $17.72.

We can use these data points to form a system of linear equations.

Let's solve it to find the equation of the linear function.

Using the point-slope form of a linear equation:

y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope, we can substitute the values:

For the first data point:

x1 = 43

y1 = 19.41

Using the second data point:

x2 = 56

y2 = 17.72

The slope (m) can be calculated as:

m = (y2 - y1) / (x2 - x1)

m = (17.72 - 19.41) / (56 - 43)

m = -1.69 / 13

m ≈ -0.13

Now, we can use the point-slope form with one of the data points to find the equation of the linear function:

Using (x1, y1) = (43, 19.41):

y - 19.41 = -0.13(x - 43)

Simplifying the equation:

y - 19.41 = -0.13x + 5.59

y = -0.13x + 24

Now that we have the equation of the linear function, we can substitute x = 65 to find the remaining credit after 65 minutes:

y = -0.13(65) + 24

y ≈ $15.45

Therefore, the remaining credit after 65 minutes of calls is approximately $15.45.

Answer:

The passenger train is traveling at 45 mph, and the freight train is traveling at 27 mph.

Step-by-step explanation:

Let's assume the speed of the passenger train is represented by x mph.

According to the given information, the freight train leaves the depot 2 hours before the passenger train. Therefore, when the passenger train starts, the freight train has already been traveling for 2 hours.

Let's represent the speed of the freight train as (x - 18) mph, which is 18 mph slower than the passenger train.

Now, we know that the passenger train overtakes the freight train in 3 hours. This means that the passenger train traveled for 3 hours, while the freight train traveled for 3 + 2 = 5 hours.

Since speed = distance/time, we can set up the following equation based on the distances covered by each train:

Distance covered by passenger train = Distance covered by freight train

Using the formula, distance = speed × time, we get:

x × 3 = (x - 18) × 5

Simplifying the equation:

3x = 5x - 90

90 = 5x - 3x

90 = 2x

Dividing both sides by 2:

45 = x

So, the speed of the passenger train is 45 mph.

The speed of the freight train is 45 - 18 = 27 mph.

Step-by-step explanation:

To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.

In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.

To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.

The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.

Therefore, the correct answer is 03.841.

As the degrees of freedom increase, the Chi-square distribution becomes less skewed.

Option C is the correct answer.

We have,

The Chi-square distribution is a probability distribution that is commonly used in statistics.

It is often used in hypothesis testing and in constructing confidence intervals for population variances.

The shape of the Chi-square distribution depends on the degrees of freedom (df). The degrees of freedom represent the number of independent pieces of information used to estimate a parameter or make an inference.

When the degrees of freedom are small, such as 1 or 2, the Chi-square distribution is highly skewed to the right.

This means that the distribution has a long tail on the right side and is concentrated toward the lower values.

However, as the degrees of freedom increase, the Chi-square distribution becomes less skewed.

The distribution becomes more symmetrical and approaches a bell shape, similar to the shape of a normal distribution. This means that the values are more evenly spread out and there is less concentration towards the lower values.

Therefore,
