You can use indirect measurement to estimate the height of a building. First, measure your distance from the base of the building and the distance from the ground to a point on the building that you are looking at. Maintaining the same angle of sight, move back until the top of the building is in your line of sight. Answer both A and B

Answers

Answer 1

The building is perfectly vertical and the observer is at a consistent height above the ground.

A) Explain how the method of indirect measurement can be used to estimate the height of a building?

The method of indirect measurement can be used to estimate the height of a building by using similar triangles and the principles of proportionality. First, the distance from the base of the building to the observer and the distance from the ground to a known point on the building are measured. By maintaining the same angle of sight, the observer can move back until the top of the building is in their line of sight. At this point, a second pair of measurements is taken: the distance from the new location to the base of the building and the height of the visible portion of the building from the ground. By using the principles of proportionality between similar triangles, the height of the entire building can be estimated.

Specifically, the ratio of the height of the known point on the building to the distance from the observer to that point can be set equal to the ratio of the height of the entire building to the distance from the observer to the base of the building. This proportion can be solved algebraically to find the estimated height of the entire building.

B) What are some potential sources of error or inaccuracy in this method of estimation?

There are several potential sources of error or inaccuracy in this method of estimation. One major source of error is the assumption that the two triangles being compared are similar. If the angle of sight is not maintained exactly or if the ground is not perfectly level, the triangles may not be similar and the estimated height may be incorrect.

Additionally, the accuracy of the estimated height depends on the accuracy of the distance measurements. If the distances are not measured precisely, the estimated height will be proportionally less accurate.

Finally, this method assumes that the building is perfectly vertical and that the observer is at a consistent height above the ground. If the building is not perfectly vertical or the observer's height above the ground changes, this can also affect the accuracy of the estimated height.

Establecieron un precio por metro cuadrado de 800 pesos y tienen que calcular el costo, con base en los metros cuadrados que tiene cada lote. Determina el área de cada terreno, así como su precio

Answers

The area and cost of each of the lots is given below

What is the area?

The area and cost of each of the lots is calculated below

To calculate the rectangle trapezoid, it will be:

B = 140m

h = 50m

b = 70m

Note that Area of Lot 1 : A =(B+b)h/2

Hence Height will be:

A= (140m+ 70m) 50m/2

A = 5250 m²

Cost: C = 5250m² *800 pesos = $4,200,000

Lot 2 is another rectangle trapezoid:

B = 150m

b = 80m

h = 50m

Area: A= (150m+ 80m)50m/2

A = 5750 m²

Cost: C = 5750m²  x 800 pesos = $4,600,000

So, for Lot 3 which is a rectangle:

b = 70m

to = 50m

Area: A =a x b

W=50m x 70m

A  = 3500 m²

Cost: C = 3500m² x 800 pesos = $2,800,000

Lot 4 is a right triangle:

b = 70m

h = 50m

Area: A =b x h/2

A= (50m x 70m)/2

A = 1750 m²

Cost: C = 1750 m² x 800 pesos = $1,400,000

So for Lot 5 that is a rhomboid:

b = 150 base meters

h=50m

Area: A=b x h

A= (150m  x  50m

H = 7500 m²

Cost: C = 7500m² x  800 pesos = $6,000,000

So, for Lot 6 that is an isosceles triangle:

b = 140m

h= 50m

Area: A =b x h/2

A= (140m x  50m)/2

A = 3500 m²

Lastly, the Cost: C = 3500m²  x 800 pesos = $2,800,000

Answers

The manager will need to pay $244.95 to purchase the silverware, including sales tax.

What is decimal?

Decimals are numbers that have two parts: a whole number part and a fractional part separated by a decimal point.

According to the given information:

If the silverware costs $230 and the sales tax is 6.5%, we need to calculate the amount of tax that will be added to the cost of the silverware:

Tax = 6.5% of $230 = 0.065 x $230 = $14.95

So the total cost of the silverware including tax is:

$230 + $14.95 = $244.95

Therefore, the manager will need to pay $244.95 to purchase the silverware, including sales tax.

Victoria drove 76 miles, burning 4 gallons of gasoline. She knows the total number of miles she can drive is proportional to the number of gallons of gas she burns and wants to create an equation that can be used to predict the number of miles she can drive for any number of gallons of gas used. Drag the correct values to create an equation which will accurately represent the total number of miles, m, Victoria should expect to be able to drive if she uses g gallons of gasoline

Answers

The equation that represents the total number of miles, m, Victoria should expect to be able to drive if she uses g gallons of gasoline is m = (19g).

We can determine the proportionality constant by dividing the total number of miles driven (76) by the number of gallons of gasoline burned (4), which gives us 19 miles per gallon (76/4 = 19).

We can then use this proportionality constant to create the equation m = (19g), where m represents the total number of miles Victoria should expect to be able to drive if she uses g gallons of gasoline. This equation tells us that for every additional gallon of gasoline burned, Victoria should expect to be able to drive an additional 19 miles.

For example, if Victoria were to burn 6 gallons of gasoline, she should expect to be able to drive 114 miles (6 x 19 = 114). This equation assumes that Victoria's car has a constant fuel efficiency of 19 miles per gallon.

Required:


a. Find the long-term average number of people in line.


b. Find the long-term probability that there are at least two people in line

Answers

The required answer is P(at least 2) = P(at least 1) * (1/2) = (1 - e^(-λ * a)) * (1/2)

a. To find the long-term average number of people in line, we will use the following formula:

Average number of people in line = λ * a

Here, λ is the arrival rate of customers following a Poisson process, and a is the average time taken by the chef to process an order.

b. To find the long-term probability that there are at least two people in line, we first need to calculate the probability that there is at least one person in line. Then, we will subtract this probability from 1 to find the probability of having at least two people in line.

Probability of at least one person in line = 1 - Probability of no one in line

Since the arrival of customers follows a Poisson process, the probability of having no one in line is given by:

P(0) = e^(-λ * a)

Thus, the probability of at least one person in line is:

P(at least 1) = 1 - e^(-λ * a)

Now, we can calculate the probability of having at least two people in line by considering that the second person joins the line with probability 1/(1 + 1) = 1/2. So, the probability of at least two people in line is:

P(at least 2) = P(at least 1) * (1/2) = (1 - e^(-λ * a)) * (1/2)

3. The insurance company also offers safety glass coverage. There is a 50% chance of no repairs ($0), a 30% chance of minor repairs ($50), and a 20% chance of full replacement ($300). Which plan for optional safety glass coverage has the lower expected cost?

Enter your answer.

Answers

Plan C has the lower expected cost, so, this is best to minimize costs for safety glass coverage.

How can we compare the plans?

In order to compare expected cost of Plan C and D, we must calculate expected payout for each plan and add to the premium.

For Plan C, expected payout is:

= 0.5*(0) + 0.3*(50) + 0.2*(300)

= 15 + 60

= 75

The total expected cost of Plan C is:

= 75 + 50 + 20

= 145

For Plan D, expected payout is:

= 0.5*(0) + 0.3*(50) + 0.2*(300)

= 15 + 60

= 75

The total expected cost of Plan D is:

= 75 + 100 + 0

= 175

Therefore, the Plan C has the lower expected cost.

Answers

(a) Miguel had the greatest spread in training times.

(b) The middle 50% of Adam's training times had the least spread.

(a) To find the greatest spread in training times, we need to calculate the range of each person's training times. Range is the difference between the maximum and minimum values. Comparing the ranges, we can say that Miguel had the greatest spread in training times since his range is the largest.

(b) The middle 50% of the training times refers to the interquartile range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1).

To find the least spread in the middle 50% of the training times, we need to compare the IQRs of each person. Adam's IQR is the smallest, which means the middle 50% of his training times had the least spread.

(c) The answers to parts (a) and (b) indicate that Miguel had a wider range of training times compared to Adam. However, Adam's middle 50% of training times had the least spread.

Answer is:

For the south region, the proportion of sales from current stores is approximately 58 %.

because this proportion is relatively close to the sales director's statistical model, the data is consistent with the model.

The given information states that the proportion of sales from current stores in the South region is approximately 58%. This value falls within the range of the sales director's statistical model, which could be an estimated value or a range of values based on past data or other sources. Since the proportion of sales falls within the expected range, the data is consistent with the model. This means that the actual value observed is not significantly different from the expected value, and there is no evidence to suggest that the model needs to be revised or updated.

Therefore, the answer to the second drop-down menu is "consistent". If the actual proportion of sales from current stores in the South region was significantly different from the expected value in the sales director's statistical model, then the answer would be "inconsistent".

We also know that b is the base of the triangle, 3.

So, solve for c:

4+9=c²

15=c²

take the square root of both sides

c=3.9

So, the spider and the fly are 3.9 ft apart from each other

Hope this helps :)

Answer:

3.6 feet

Step-by-step explanation:

The Pythagorean theorem states that a^2+b^2=c^2, where c is the hypotenuse, or longest side of the triangle opposite to the right angle, and a and b are the two legs of the triangle (the other two sides.)

In the question, sides a and b are given as 2ft and 3ft long. Plugging 2 and 3 into the equation, we will get that 2^2+3^2=c^2. 2 x 2 = 4 and 3 x 3 = 9, so 4 + 9 = c^2, or, c^2 = 13.

However, this is still c^2, not c, so we must take the square root of both sides. This is because the equation is now essentially saying that c x c = 13, so if we find a number that when multiplied by itself equals 13, that number will be c. to do this, we must take the square root of 13. This will give us an irrational number- approximately 3.605551275. The question asks to round it to the nearest tenth though, so this will simply become 3.6.

In the context of this question, it means that the spider and the fly are 3.6ft apart.

How can you use rational expressions and equations to describe relationship and solve problems?

Answers

Rational expressions and equations can be used to describe relationships and solve problems that involve proportions or rates of change.

They involve expressions that are fractions of polynomials, where the numerator and denominator can be thought of as values that change according to some variable.

For example, rational expressions can be used to represent rates of change in physics or finance, such as the speed of an object or the interest rate on a loan. By setting up equations with rational expressions, we can solve for unknown values or relationships between variables.

Rational equations can also be used to describe relationships between quantities that are proportional, such as the volume of a container and the amount of liquid it can hold. By solving for an unknown variable in a rational equation, we can determine the relationship between the two quantities and use it to make predictions or solve practical problems.

Statistics from Cornell's Northeast regional Climate Center indicate that Ithaca, NY, gets an average of 36. 1 inches of rain each year with a


standard deviation of 5. 2 inches,


My friend stayed in Ithaca, NY there for 10 years, she said that the average while she was there was less than 34 inches. What is her vscore for


the 10 years?


(Round to the thousandth place) (Use a Standard Deviation that is rounded to the thousandth place)

Answers

Rounded to the thousandth place, your friend's z-score for the 10 years is approximately -0.404.

To calculate your friend's z-score for the 10 years she stayed in Ithaca, NY, you can use the following formula:

z = (X - μ) / σ

where:
- z is the z-score
- X is the sample mean (in this case, 34 inches)
- μ is the population mean (in this case, 36.1 inches)
- σ is the standard deviation of the population (in this case, 5.2 inches, rounded to 5.200 for thousandth place)

Plugging in the values:

z = (34 - 36.1) / 5.200
z = -2.1 / 5.200
z = -0.404

Therefore, your friend's z-score for the 10 years is approximately -0.404, rounded to the thousandth place.

For what values of a and b will this equation have infinitely many solutions?

5(x + 3) = a(x + 4) + 3x + b

Answers

Answer: To have infinitely many solutions, the equation must be true for all values of x. In other words, the left side and right side of the equation must be equivalent, meaning that the coefficients of x on both sides of the equation must be equal, and the constant terms on both sides must be equal.

We can simplify the given equation as follows:

5(x + 3) = a(x + 4) + 3x + b

5x + 15 = ax + 4a + 3x + b

Simplifying further, we get:

8x + 4a + b = 5x + 15

Rearranging terms, we get:

3x + 4a + b - 15 = 0

For this equation to have infinitely many solutions, the coefficients of x on both sides must be equal to zero, meaning that:

3 = 0

This is not possible, so the equation cannot have infinitely many solutions for any values of a and b.

Therefore, there are no values of a and b for which the given equation will have infinitely many solutions.

The outside of a closed glass display case measures 22" x 15" x 12". The glass is half inch thick. How much air is contained in the case

Answers

The volume of the air in the container is: 3,585.125 in³

What is the Volume of the Box?

The volume of a box or cuboid is given by the formula:

V = L * W * H

Where:

L is length

W is width

H is height

We are given the external dimensions as:

Length = 22 inches

Width = 15 inches

Height = 12 inches

Since the glass is 1/2 inch thick, then the interior dimensions are:

New length = 22 - 1/2 = 21.5 inches

New Width = 15 - 1/2 = 14.5 inches

New height = 12 - 1/2 = 11.5 inches

Thus:

Volume of air in container = 21.5 * 14.5 * 11.5

= 3,585.125 in³

Find the inverse of the function

Answers

The inverse of the function f(x) = √(x+1) is [tex]f^-1[/tex](x) = x² - 1.

What is inverse function?

Given a function f(x), its inverse function, denoted as [tex]f^-1[/tex](x), is a function that takes the output of f(x) and returns the original input. In other words, if y = f(x), then x = [tex]f^-1[/tex](y).

According to question:

To find the inverse of the function f(x), we follow these steps:

Step 1: Replace f(x) with y:

   y = √(x+1)

Step 2: Interchange x and y:

   x = √(y+1)

Step 3: Solve for y:

   x² = y+1

   y = x² - 1

Step 4: Replace y with f^-1(x):

   f^-1(x) = x² - 1

Therefore, the inverse of the function f(x) = √(x+1) is [tex]f^-1[/tex](x) = x² - 1.

To verify this, we can check that ([tex]f^-1[/tex] o f)(x) = x and (f o [tex]f^-1[/tex])(x) = x for all x in the domain of the functions:

([tex]f^-1[/tex] o f)(x) = [tex]f^-1[/tex](f(x)) = (√(x+1))² - 1 = x

(f o [tex]f^-1[/tex])(x) = f([tex]f^-1[/tex](x)) = √((x² - 1) + 1) = √(x²) = |x| + 1

Since the range of f(x) is [0, infinity), we restrict the domain of [tex]f^-1[/tex](x) to [1, infinity) to ensure that the inverse is a function.
