Since x > 0, the tangent of f'(x) is always positive, and the denominator is always positive. Therefore, f'(x) is always positive, which means that f(x) is always increasing and can only cross the x-axis once. Hence, f(x) has only one root on its entire domain.

To find the y-intercept of line L, we need to determine the equation of line L.

Since line L is tangent to the graph of y = ex at the point (k, ek), the slope of line L must be equal to the slope of the tangent line to y = ex at (k, ek), which is simply ek.

Therefore, the equation of line L is:

y - ek = ek(x - k)

Simplifying, we get:

y = ekx - ek2

To find the y-intercept, we set x = 0 and solve for y:

y = ek(0) - ek2 = -ek2

Therefore, the y-intercept of line L is -ek2.

We need to find the value of k such that the y-intercept of line L is 1/2.

-ek2 = 1/2

Solving for k, we get:

k = ln(sqrt(2))

So the answer is (A) 0.405.

To prove that the function has only one root on its entire domain, we take the derivative of f(x) and show that it is always positive.

f(x) = ln(x) - 1/x

f'(x) = 1/x + 1/x^2 = (x+1)/x^2

Answer:    2,318 miles

Step-by-step explanation:

Answer:

YZ = 12

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of XZ = 13

Lenght of XY = 5

Lenght of YZ =?

The length of YZ can be obtained by using pythagoras theory since the figure is a right angle triangle. This can be obtained as follow:

XZ² = XY² + YZ²

13² = 5² + YZ²

169 = 25 + YZ²

Collect like terms

169 – 25 = YZ²

144 = YZ²

Take the square root of both side.

YZ = √144

YZ = 12

Therefore, the length of YZ is 12

RM =20

Step-by-step explanation:

Find the diagram of the parallelogram attached

From the diagram, GP = PA

8x = 2x+18

8x - 2x = 18

6x = 18

x = 18/6

x = 3

Since RM = 2RP

RM = 2(x+7)

RM = 2(3+7)

RM = 2(10)

RM =20

Hence the length of RM is 20

The probability that the sample mean would differ from the true mean by more than $2.5 is 0.0062

Mean cost of the five pound shrimp bag = $40

Variance of the five pound shrimp bag = $36

The number of the shrimp bag = 43

The given mean value = $2.5

The z-score = $2.5

The probability of the sample mean differ by $2.5 from the true mean can be calculated by

  P(z > 2.5) = 1 - P(z < 2.5)

From the z table , we can get the value of  z < 2.5 which is 0.9938

    P(z > 2.5) = 1 - 0.9938

   P(z > 2.5) = 0.0062

Therefore , the probability of sample mean from the true mean by 2.5 is 0.0062

The product of 2 odd numbers will be odd and any number that is a multiple of 2 is even.

Odd numbers are those numbers that cannot be divided into two equal parts, whereas even numbers are those numbers that can be divided into two equal parts

let the odd number be 2x+ 1

and the even number be 2x

Now, the product of two odd numbers

=(2x + 1)(2x + 1)

= 4x² + 4x + 1.

Here, 4x² is even because 4x² can be expressed as multiple of 2.

Also, 4x is even because 4x can be expressed as multiple of 2.

So, the expression 4x² + 4x + 1 is odd because an even number + 1 is odd.

Hence, the product of 2 odd numbers will be odd.

Option C. Regression models can be used for both linear and non-linear associations, but they are particularly well-suited for linear relationships.

Regression models are useful for modeling the relationship between variables, particularly for predicting the value of one variable based on the value of another.

Linear regression models are used for linear associations, while non-linear regression models are used for non-linear associations. However, even for non-linear associations, linear regression models can be useful for approximating the relationship between variables in certain cases. Nonetheless, in general, non-linear regression models are more appropriate for non-linear associations.

Therefore, if the null hypothesis is rejected, the evidence supports the alternative hypothesis. This means that the test results provide enough evidence to conclude that the alternative hypothesis is more likely true than the null hypothesis.

In hypothesis testing, if the null hypothesis is rejected, it means that there is sufficient evidence to support the alternative hypothesis. A null hypothesis is a statement that there is no significant difference or relationship between variables, while the alternative hypothesis states that there is a significant difference or relationship. To determine if the null hypothesis is true or not, we conduct a statistical test and calculate the p-value. If the p-value is less than the level of significance, usually set at 0.05, we reject the null hypothesis and accept the alternative hypothesis. Therefore, the correct answer is that the evidence supports the alternative hypothesis. This means that we have found significant results that support our research hypothesis.
Keep in mind that rejecting the null hypothesis does not prove the alternative hypothesis, but it does suggest that it's more plausible based on the data collected.

Therefore, if the null hypothesis is rejected, the evidence supports the alternative hypothesis. This means that the test results provide enough evidence to conclude that the alternative hypothesis is more likely true than the null hypothesis.

Step-by-step explanation:

Answer:

\(y = -4x + 5\)

Step-by-step explanation:

We want to find the equation of the line that is perpendicular to:

\(\displaystyle y = \frac{1}{4} x - 5\)

And which passes through the point (2, -3).

Recall that the slopes of perpendicular lines are negative reciprocals of each other.

In other words, since the slope of the original line is 1/4, the slope of the perpendicular line will be -4.

We are also given that it passes through the point (2, -3). Hence, we can consider using the point-slope form:

\(\displaystyle y - y_1 = m(x- x_1)\)

Substitute:

\(\displaystyle y - (-3) = -4 (x - (2))\)

Simplify:

\(y + 3 = -4(x - 2)\)\(y = -4x + 5\)

Distribute:

\(y + 3 = -4x +8\)

And subtract:

\(y = -4x + 5\)

In conclusion, our equation is:

\(y = -4x + 5\)

The probability that all three letters are identical is the product of the probability that each individual letter is identical, which is (1/26) * (1/26) * (1/26) = (1/26)^3.

The probability that all three letters selected are identical would be (1/26)^3, assuming that the pool of letters contains an equal number of each letter of the alphabet (a, b, c, ..., z) and that each letter is selected independently and with replacement. This is because there is only a 1 in 26 chance of selecting any given letter on the first draw, and the same is true for the second and third draws. Since all three draws are independent, the probability that all three letters are identical is the product of the probability that each individual letter is identical, which is (1/26) * (1/26) * (1/26) = (1/26)^3.

The closest percent markup cost to the bracelets Anna sells is 181%.

To determine the percent markup cost for the bracelets Anna sells, we need to calculate the difference between the selling price and the cost price, and then express it as a percentage of the cost price.

The selling price of the bracelets is $45, and the cost price is $16.

Markup = Selling Price - Cost Price

= $45 - $16

= $29

Now, to calculate the percent markup cost, we divide the markup by the cost price and multiply by 100:

Percent Markup Cost = (Markup / Cost Price) \(\times\) 100

= ($29 / $16) \(\times\) 100

= 181.25

Rounded to the nearest whole number, the percent markup cost is approximately 181%.

Therefore, the closest percent markup cost to the bracelets Anna sells is 181%.

This means that Anna is charging customers approximately 181% more than what it cost her to make the bracelets.

The markup cost represents the additional amount she adds to cover expenses, overhead, and to make a profit.
