the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride is approximately 51.54 degrees.

What is Angle of Elevation?

The angle of elevation is the angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is the angle of elevation.

To find the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride in Disney World, Florida, we can use trigonometry.

The angle of elevation can be calculated using the tangent function, which relates the opposite side (height of the tower) to the adjacent side (distance from the base to where Josh is standing).

Tangent(theta) = Opposite / Adjacent

In this case, the opposite side is the height of the tower (199 feet) and the adjacent side is the distance from the base to where Josh is standing (132 feet).

Tangent(theta) = 199 / 132

To find the angle of elevation (theta), we can take the inverse tangent (arctan) of both sides:

theta = arctan(199 / 132)

Using a calculator, the approximate value of the angle of elevation is:

theta ≈ 51.54 degrees

Therefore, the angle of elevation from the point where Josh is standing to the top of the Tower of Terror ride is approximately 51.54 degrees.

The angle D is 29 degrees, side DF is 9 and side DE is 10.3 rounded to nearest tenth.

Assuming the remaining angle of triangle to be x. Calculating the same we get:

90 + 61 + x = 180

151 + x = 180

x = 180 - 151

x = 29 degrees

Now, cos theta = base (EF)/hypotenuse (DE) (for 61 degree angle)

cos 61 = 5/hypotenuse

Hypotenuse = 5/cos 61

Hypotenuse = 10.3

Working out sin 90 degree to find DF

sin 61 = perpendicular (DF)/ hypotenuse (DE)

0.87 = Perpendicular/10.31

Perpendicular = 0.87 × 10.31

Perpendicular = 9

Hence, the remaining angle is 29 degrees and sides are 10.3 and 9.

Therefore, the only critical number of g(y) is y = -1/12.

To find the critical numbers of a function, we need to find the values of the independent variable (in this case, y) at which the derivative of the function is zero or undefined.

First, we find the derivative of g(y):

g'(y) = 1 - 12y - 2

Setting g'(y) = 0, we get:

1 - 12y - 2 = 0

-12y = 1

y = -1/12

Since the derivative is defined for all values of y, there are no values of y at which it is undefined.

The critical points occur when the derivative of the function is equal to zero or undefined. The absolute maximum value of f(x) = ln(x)/x is approximately 0.3679.

Taking the derivative of f(x), we get:

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

Setting this equal to zero, we get:

1 - ln x = 0

ln x = 1

x = e

We also need to check for any values of x that make the derivative undefined. The derivative is undefined when x = 0.

Now we need to check the values of f(x) at these critical points and the endpoints of the domain, which is (0, infinity).

f(0) is undefined as ln 0 is undefined.

f(e) = (ln e)/e = 1/e

As x approaches infinity, f(x) approaches zero.

So the absolute maximum value of f(x) is 1/e, which occurs at x = e.

To find the absolute maximum value of the function f(x) = ln(x)/x, we need to follow these steps:

Step 1: Determine the domain of the function
The function is defined for x > 0, since ln(x) is only defined for positive values of x.

Step 2: Find the first derivative of the function
Using the quotient rule, we find the first derivative:
f'(x) = (1/x - ln(x))/x^2

Step 3: Find the critical points
To find the critical points, set the first derivative equal to zero and solve for x:
(1/x - ln(x))/x^2 = 0
1/x - ln(x) = 0
ln(x) = 1/x

Step 4: Solve the equation for x
The equation ln(x) = 1/x does not have a simple algebraic solution. However, using numerical methods (e.g. the Newton-Raphson method) or by graphing the two functions, we can find that the critical point occurs at x ≈ 3.591.

Step 5: Evaluate the function at the critical point
Now we plug this value of x into the original function to find the absolute maximum value:
f(3.591) ≈ ln(3.591)/3.591 ≈ 0.3679

Thus, the absolute maximum value of f(x) = ln(x)/x is approximately 0.3679.

Rolling two 8-sided dice will yield 8 outcomes that result in a sum that is a square of something.

To find the number of outcomes that result in a sum that is a square, we need to determine the possible sums and identify which of them are perfect squares.

Let's analyze the possible outcomes when rolling two 8-sided dice. Each die has 8 faces, numbered from 1 to 8. Therefore, the maximum sum we can obtain is 8 + 8 = 16.

To determine the number of outcomes that result in a square sum, we need to identify the perfect square sums between 2 and 16. The perfect squares in this range are 4, 9, and 16.

Now, let's find the outcomes that yield these square sums:

To obtain a sum of 4, we can roll (1, 3), (2, 2), or (3, 1) on the two dice. That's 3 possible outcomes.

To obtain a sum of 9, we can roll (3, 6), (4, 5), (5, 4), or (6, 3) on the two dice. That's 4 possible outcomes.

To obtain a sum of 16, we can only roll (8, 8) on the two dice. That's 1 possible outcome.

Therefore, there are a total of 3 + 4 + 1 = 8 outcomes that result in a sum that is a square.

The total cost of the phone, including taxes, is $150.

When buying a new phone, it is important to factor in the sales tax in order to determine the total cost. In this case, Desmond paid 8.5% sales tax on the phone and the amount came out to be $12.75. We can use this information to determine the total cost of the phone.

To calculate the total cost of the phone, we can start by finding out what percentage of the original cost $12.75 represents. To do this, we can set up a proportion:

8.5% = $12.75 / X

where X is the original cost of the phone.

To solve for X, we can cross-multiply and simplify:

8.5X = $12.75
X = $12.75 / 8.5%
X = $150

Therefore, the total cost of the phone, including taxes, is $150. It is important to note that sales tax rates may vary by state and location, so it is always a good idea to double-check the tax rate in your area before making a purchase.

To estimate how many of the next 720 shirts claimed should be size small, we can use the proportion of people who have taken size small so far.

First, we need to find the total number of people who have claimed T-shirts:

110 (size small) + 154 (other sizes) = 264

The proportion of people who have taken size small so far is:

110/264 ≈ 0.4167

This means that approximately 41.67% of people have taken size small so far.

To estimate how many of the next 720 shirts claimed should be size small, we can multiply the proportion by the total number of shirts:

0.4167 × 720 ≈ 300

Therefore, we can expect that approximately 300 of the next 720 shirts claimed should be size small.

However, it's important to note that this is just an estimate based on the data so far.

To estimate the sum, we can use the formula for the sum of an infinite geometric series, which is a/(1-r), where a is the first term and r is the common ratio.

In this case, the first term is (2(1) + 1)−9 = 1/512, and the common ratio is 2/3. Therefore, the sum can be estimated as (1/512)/(1-(2/3)) = 1/2560 = 0.000390625.

However, since this only gives us two decimal places of accuracy, we need to add more terms to the sum to get a more accurate estimate. By adding more terms using a calculator or computer program, we find that the sum converges to approximately 0.00253, correct to five decimal places.

Answer: What Must the Cooker Setting Be if it Takes 3 minutes to Boil the Water?

Step-by-step explanation: We can start by using the formula for inverse proportionality: T = k/H, where k is a constant of proportionality. We can find the value of k by using the information given: when H = 7.5, T = 240.

240 = k/7.5

Solving for k, we get:

k = 1800

Now we can use this value of k and the new value of T (3 minutes = 180 seconds) to find the new value of H:

180 = 1800/H

Solving for H, we get:

H = 10

Therefore, the cooker setting must be 10 if it takes 3 minutes to boil the water.

To write the equation of a line parallel to 2y=5x+10 and goes through point (6,12), you first need to find the slope of the given line. You can do this by rearranging the equation into slope-intercept form y=mx+b, where m is the slope.

Rearranging 2y=5x+10 gives y=(5/2)x+5. So the slope of the given line is 5/2. Since parallel lines have the same slope, the slope of the new line will also be 5/2.

Next, you can use point-slope form to find the equation of the new line. The point-slope form is y-y1=m(x-x1), where (x1,y1) is a point on the line and m is the slope. Plugging in the point (6,12) and the slope 5/2 gives y-12=(5/2)(x-6).

Finally, you can rearrange this equation into slope-intercept form to get y=(5/2)x-3. So the equation of the line parallel to 2y=5x+10 and goes through point (6,12) is y=(5/2)x-3.

The third odd number is 7. So, adding 7 to 11 gives 18. But we need to add one more to get the next odd number, which is 19. So, adding 8 to 11 gives 19.

The fourth odd number is 9. So, adding 9 to 19 gives 28. But we need to add one more to get the next odd number, which is 29. So, adding 10 to 19 gives 29.

The fifth odd number is 11. So, adding 11 to 29 gives 40. But we need to add one more to get the next odd number, which is 41. So, adding 12 to 29 gives 41.

The sixth odd number is 13. So, adding 13 to 41 gives 54. But we only need the next number in the sequence, which is 47.

The statement "this is an example of sampling without replacement" is true. When it is mentioned that there are 130 eligible people, and out of those, 60 are women, it implies that the selection is done without replacement.

This means that once someone is selected or chosen, they are removed from the pool of eligible people for subsequent selections.

b) To calculate the probability that all four of the excused potential jurors are women, we need to consider the number of women in the eligible pool and the reduced pool after each excusal.

Initially, there are 60 women out of 130 eligible people. After the first excusal, there are 129 eligible people remaining, with 59 women. After the second excusal, there are 128 eligible people remaining, with 58 women. After the third excusal, there are 127 eligible people remaining, with 57 women. Finally, after the fourth excusal, there are 126 eligible people remaining, with 56 women.

To calculate the probability, we multiply the probabilities of each excusal:

P(all four are women) = (60/130) * (59/129) * (58/128) * (57/127)

Calculating this expression gives us the probability that all four excused potential jurors are women.
