The ratio of the area of triangle XBY to the area of triangle ABC is 9/25. The height of XBY with respect to BY is 24/7, and the height of ABC with respect to BC is 40/7.

To find the ratio of the area of triangle XBY to the area of triangle ABC, we need to first find the heights of both triangles with respect to base BC.

Let's use the formula for the area of a triangle

Area = 1/2 * base * height

For triangle ABC, the base is BC, which has length 5, and let h₁ be the height of triangle ABC with respect to BC.

Area of ABC = 1/2 * 5 * h₁

For triangle XBY, the base is BY, which has length 3, and let h₂ be the height of triangle XBY with respect to BY.

Area of XBY = 1/2 * 3 * h₂

Since the triangles share the same base, we can use the following proportion to find the ratio of their heights

h₁/h₂ = BC/BY

h₁/h₂ = 5/3

We can solve for h₂

h₂ = (3/5)h1

Now, we need to find h1. We can use the fact that the area of triangle ABC is equal to the sum of the areas of triangles ABY and BCY.

Area of ABC = Area of ABY + Area of BCY

1/2 * 5 * h₁ = 1/2 * 3 * (3+h2) + 1/2 * 2 3/2 * (2 3/2 - h₂)

Simplifying the above equation and substituting h₂ = (3/5)h1, we get

5h₁ = 3(3 + 8/5 h₁) + 3h₁/5

Solving for h1, we get

h₁ = 40/7

Substituting h₁ = 40/7 and h₂ = (3/5)h₁ = 24/7 into the formulas for the areas of the triangles, we get

Area of ABC = 1/2 * 5 * 40/7 = 100/7

Area of XBY = 1/2 * 3 * 24/7 = 36/7

Therefore, the ratio of the area of triangle XBY to the area of triangle ABC is

Area of XBY / Area of ABC = (36/7) / (100/7) = 9/25

Hence, the required ratio is 9/25.

75°/360° = 5/24

Area of sector = (5/24)(π)(10^2)

Length of arc = (5/24)(2π)(10)

= 25π/6 inches

The area of triangle CDE is 17.5 square units.

To find the area of triangle CDE, we can use the general formula:

Area = 1/2 * base * height where the base and height are two sides of the triangle. We can also use the distance formula to find the lengths of these sides.

First, let's find the length of side CD: CD = sqrt[(7-4)² + (8-4)²] = sqrt[3² + 4²] CD = √25 = 5

Next, let's find the length of side DE: DE = sqrt[(2-7)² + (9-8)²] = sqrt[5² + 1²] = DE = √26

Now, we need to find the height of the triangle. One way to do this is to use the formula for the area of a triangle:

Area = 1/2 * base * height

Rearranging this formula, we get: height = 2 * Area / base

We know the base is CD, which we found to be 5. We can find the area of triangle CDE using the shoelace formula, which gives:

Area = 1/2 * |(48 + 79 + 24) - (47 + 82 + 94)| = 17.5

Therefore, the height of triangle CDE is: height = 2 * Area / base = 2 * 17.5 / 5 = 7

Now we can use the formula for the area of a triangle to find the area of triangle CDE: Area = 1/2 * base * height = 1/2 * 5 * 7 = 17.5

Therefore, the area of triangle CDE is 17.5 square units.

If a hypothesis test is conducted to see if there is evidence that the average wait time is 5 minutes, the p-value is 0.040.

To calculate the p-value for the hypothesis test, we need to perform the following steps:

Step 1: State the null and alternative hypotheses.

In this case, the null hypothesis (H0) is that the average wait time for customers during the lunch hour is 5 minutes. The alternative hypothesis (Ha) is that the average wait time is not 5 minutes.

Step 2: Determine the test statistic.

We can use a t-test since we do not know the population standard deviation. We calculate the t-value using the formula:

t = (x' - μ) / (s / √n)

where x' is the sample mean, μ is the population mean (5 minutes), s is the sample standard deviation, and n is the sample size (15).

Step 3: Calculate the p-value.

We can use a t-distribution table or software to find the p-value associated with our calculated t-value. Alternatively, we can use the t-test function in Excel or other statistical software to calculate the p-value directly.

Assuming a two-tailed test and a significance level of 0.05, if the p-value is less than 0.05, we reject the null hypothesis in favor of the alternative hypothesis. If the p-value is greater than 0.05, we fail to reject the null hypothesis.

Suppose the sample mean is 6.2 minutes, the sample standard deviation is 1.3 minutes, and the sample size is 15. Then the t-value is:

t = (6.2 - 5) / (1.3 / √15) = 2.22

Using a t-distribution table or software with 14 degrees of freedom (15 - 1), we find the p-value to be approximately 0.040, which is less than 0.05. Therefore, we reject the null hypothesis and conclude that there is evidence to suggest that the average wait time for customers during the lunch hour is not 5 minutes.

Part(2),

The formula for the shadow is,

6² + x² = 16²

A basic mathematical theorem relating to the lengths of a right-angled triangle's sides is known as the Pythagorean theorem. According to this rule, the square of the length of the hypotenuse (the side that faces the right angle) in any right-angled triangle equals the sum of the squares of the lengths of the other two sides.

Part(1),

To find the angle x, we can use the inverse tangent function. Let's call the length of Joel's shadow "s". Then we have:

tan(x) = opposite/adjacent = 16/s

Taking the inverse tangent of both sides, we get:

x = tan⁻¹(16/s)

We know that Joel's height is 6 ft, so the hypotenuse of the right triangle formed by Joel and his shadow is:

= √(6² + s²)

Now we can use the Pythagorean Theorem to solve for s. Rearranging the formula for h, we have:

s = √(h² - 6²)

Substituting the value of h with the expression above, we get:

s = √((√(6² + s²))² - 6²)

Simplifying this expression, we get a quadratic equation in terms of s:

s² - 256 = 0

Solving for s, we get:

s = ±16

Since s represents the length of the shadow, it must be positive. Therefore, s = 16 ft.

Substituting s into the equation for x, we get:

x = tan⁻¹(16/16) = tan⁻¹(1) = 45°

So the measure of the angle x is 45 degrees.

log 72 to the base 2n is equal to log 18 to the base n if n is equal to [tex]2^{1/10}[/tex].

We can use the change-of-base formula to convert both logarithms to a common base, such as base 10:

log 72 / log 2n = log 18 / log n

We can simplify log 72 as follows:

[tex]log 72 = log (2^3 * 3^2) = 3 log 2 + 2 log 3[/tex]

Similarly, we can simplify log 18 as:

[tex]log 18 = log (2 * 3^2) = log 2 + 2 log 3[/tex]

Substituting these expressions into the original equation, we get:

(3 log 2 + 2 log 3) / log 2n = (log 2 + 2 log 3) / log n

Multiplying both sides by log n * log 2n, we get:

(3 log 2 + 2 log 3) log n = (log 2 + 2 log 3) log 2n

Expanding the logarithms using the power rule, we get:

[tex]3 log (n^3) + 2 log (n^2) = log (2n) + 2 log (n^3)[/tex]

Simplifying and rearranging terms, we get:

[tex]3 log (n^3) - 2 log (n^3) = log (2n) - 2 log (n^2)[/tex]

[tex]log (n^9) = log (2n / n^2)[/tex]

[tex]log (n^9) = log (2/n)[/tex]

Taking the exponential of both sides, we get:

[tex]n^9 = 2/n[/tex]

Multiplying both sides by n, we get:

n^10 = 2

Taking the 10th root of both sides, we get:

[tex]n = 2^{1/10}[/tex]

Therefore, log 72 to the base 2n is equal to log 18 to the base n if n is equal to [tex]2^{1/10}[/tex]

We add the last two numbers to get 90. This means that we can write f(x) as:

f(x) = (x - 6)(x² - 3x + 14)

To find the zeros of f(x), we need to solve the equation (x - 6)(x² - 3x + 14) = 0.

The first factor gives us x = 6.

To solve the quadratic factor, we can use the quadratic formula:

x = (-b ± sqrt(b² - 4ac)) / 2a

In this case, a = 1, b = -3, and c = 14. Substituting these values into the formula, we get:

x = (3 ± sqrt(3² - 4(1)(14))) / 2(1)

x = (3 ± sqrt(-47)) / 2

Since the square root of a negative number is not a real number, the quadratic factor does not have any real zeros.

Therefore, the zeros of f(x) are x = 6, and the complex numbers x = (3 ± sqrt(-47)) / 2.

Answer:

Step-by-step explanation:

To find the solution for p(x) = m(x), we need to set the two expressions equal to each other and solve for x:

2ln(x) - 1 = ln(x+6)

First, we can simplify the left side by using the logarithmic identity that states ln(a^b) = b ln(a):

ln(x^2) - 1 = ln(x+6)

Next, we can eliminate the natural logarithm by exponentiating both sides with the base e:

e^[ln(x^2) - 1] = e^[ln(x+6)]

e^[ln(x^2)] * e^[-1] = x + 6

x^2 * 1/e = x + 6

Multiplying both sides by e gives:

x^2 = e(x + 6)

Expanding the right side gives:

x^2 = ex + 6e

Rearranging gives:

x^2 - ex - 6e = 0

This is a quadratic equation in x. We can solve for x using the quadratic formula:

x = [e ± sqrt(e^2 + 4*6e)]/2

Simplifying gives:

x = [e ± sqrt(e^2 + 24e)]/2

Therefore, the solution for p(x) = m(x) is x = [e ± sqrt(e^2 + 24e)]/2.

Answer:

x ≈ 3.40295

Step-by-step explanation:

We want to find the value(s) of x that satisfy the equation p(x) = m(x), where p(x) = 2ln(x) - 1 and m(x) = ln(x + 6).

So, we have:

2ln(x) - 1 = ln(x + 6)

First, let's simplify the equation by using the properties of logarithms:

ln(x^2) - ln(e) = ln(x + 6)

ln(x^2/e) = ln(x + 6)

Now we can eliminate the natural logarithm by taking the exponential of both sides:

x^2/e = x + 6

x^2 - ex - 6e = 0

We can solve this quadratic equation using the quadratic formula:

x = [-(-e) ± sqrt((-e)^2 - 4(1)(-6e))] / (2(1))

Simplifying:

x = [e ± sqrt(e^2 + 24e)] / 2

Therefore, the solutions for p(x) = m(x) are:

x = [e + sqrt(e^2 + 24e)] / 2  or  x = [e - sqrt(e^2 + 24e)] / 2

Note that since the argument of the natural logarithm must be positive, we must discard the negative solution, which is not valid. So the only solution is:

x = [e + sqrt(e^2 + 24e)] / 2

We can approximate this value using a calculator or computer software. For example, if we use e = 2.71828, we get:

x ≈ 3.40295

Therefore, the solution for p(x) = m(x) is x ≈ 3.40295.

Step-by-step explanation:

Let's begin by finding the midpoint of 2 and 14. To do this, we'll add the numbers and then divide by 2.

2+14=16

16/2=8

The number that is the same distance between 2 and 14 is 8.

Now, let's find how far away each number is from 8.

8-2=6

14-8=6

2 and 14 are 6 away from 8.

Let's set up the absolute value equation using these two values.

Since 8 is the midpoint, this will be what the absolute value expression is equal to.

Since each number is 6 away from 8, this is the number (6) we will be taking away from 2 and 14.

Remember that absolute value is just distance.

In other words, 2 is 6 away from 8, and 14 is also 6 away from 8.

Or, the distance between a number x and 8 is 6.

(50/100)×60= 30

(5/100)× 60= 3

(1/100)×60= 0.6

The x-coordinate of the point of intersection of the two lines is 2.

To get the x-coordinate of the spot where the two lines intersect:

1. We can solve the system of equations given by the two lines simultaneously, which means we need to eliminate one of the variables (x or y) to obtain an equation in one variable that we can solve.

2. One way to eliminate a variable is to add or subtract the two equations in a way that cancels out one of the variables. In this scenario, we can combine the two equations:

(7x + 4y) + (9x - 4y) = 18 + 14

16x = 32

Dividing both sides by 16, we get:

x = 2

So the x-coordinate of the point of intersection of the two lines is 2.
