what type of scale is used on the map?

Answers

Answer 1

The type of scale commonly used on maps is a graphic scale, which uses a line or bar to represent distances accurately.

The type of scale used on a map is known as a map scale. It is a graphical representation that shows the relationship between distances on the map and their corresponding measurements in the real world. A map scale allows us to understand the size and proportion of features depicted on the map.

There are three main types of map scales: verbal scales, graphic scales, and representative fraction scales.

Verbal Scale: A verbal scale uses words to describe the relationship between distances on the map and real-world measurements. For example, a verbal scale might state "1 inch represents 1 mile" or "1 centimeter represents 10 kilometers." Verbal scales are commonly used on small-scale maps, where the level of detail is not as important.

Graphic Scale: A graphic scale, also known as a bar scale or linear scale, uses a line or a bar marked with specific distances. This line is divided into equal segments that represent units of measurement. By comparing the length of the line on the map to the corresponding distance in the real world, you can determine distances accurately. Graphic scales are often found on the margin or the legend of a map and are commonly used on medium- to large-scale maps.

Representative Fraction (RF) Scale: A representative fraction scale expresses the relationship between map distances and real-world distances using a ratio. For example, a representative fraction of 1:100,000 means that one unit of measurement on the map represents 100,000 of the same units in the real world. This type of scale is useful because it allows for precise calculations and conversions between map distances and real-world distances. Representative fraction scales are commonly used on topographic maps and engineering plans.

It's important to note that a map may include multiple scales to accommodate different levels of detail. For instance, a large-scale map of a city may have a more detailed scale than a small-scale map of an entire country.

6. Kibo is a Japanese laboratory on the
International Space Station. It is a cylinder
11.2 meters long with a radius of 2.2 meters.
Compare its volume to the volumes of Destiny
and Columbus.

Answers

Based on the provided information, we can say that Kibo has a volume of approximately 54.01 cubic meters.

To compare the volume of Kibo, Destiny, and Columbus, we need to calculate the volumes of each module.

The volume of a chamber can be determined utilizing the equation V = πr^2h, where r is the span and h is the level (or length for this situation) of the chamber.

For Kibo:

Radius (r) = 2.2 meters

Length (h) = 11.2 meters

V_kibo = π * (2.2^2) * 11.2

      = 4.84 * 11.2

      ≈ 54.01 cubic meters

For Destiny and Columbus, we would need their respective dimensions to calculate their volumes using the same formula.

Destiny is a U.S. laboratory module on the International Space Station. It is a multi-sided module, so we would need the measurements of each side to calculate its volume.

Columbus is a European laboratory module, which is also multi-sided.

Without the specific dimensions of Destiny and Columbus, we cannot accurately compare their volumes to Kibo. However, based on the provided information, we can say that Kibo has a volume of approximately 54.01 cubic meters.

The correct statement is that "Line p must be drawn in plane B."

If a new line, p, is drawn parallel to line /, the statement that is true is "Line p must be drawn in plane B."

To understand this, let's analyze the given information:

Planes A and B are shown.

Line m is shown in plane A.

Line n is shown in plane B.

Line / is the line that connects planes A and B.

When a new line, p, is drawn parallel to line /, it means that line p will also connect planes A and B. However, since line / itself is connecting planes A and B, line p must also lie in plane B to maintain its parallel relationship with line /. This is because parallel lines lie in the same plane.

This ensures that line p remains parallel to line / and maintains its connection between planes A and B.

It is important to note that line p being drawn in plane B does not necessarily imply that it intersects with line n. It simply means that line p lies within plane B and remains parallel to line /.

Omaha’s city council approved a special growth incentive that decreases the company’s tax burden for production levels above last year’s average. Explain how this is reflected by the Cost Function for Omaha’s factory.

Need this ASAP

Answers

a)

The cost per unit decreasing by 0.00001 for production levels above 12,000.

Given,

From the graph it is clear that the graph passes through the points (12000,0.85) and (38000,0.59).

Now,

If a line passes through two points then the slope of the line is

m = y2 - y1 / x2 - x1

The rate of change in cost per unit for production levels above 12,000 is

m = 0.59 - 0.85 / 38000 - 12000

m = -0.00001

Here negative sign represents the decreasing rate. It means the cost per unit decreasing by 0.00001 for production levels above 12,000.

b)

The function for the domain over [12000, 38000] is :

y = -0.00001x + 0.97

The point slope form of a linear function is,

(y-y1) = m (x - x1)

m = slope.

The slope of the line over [12000, 38000] is -0.00001 and the point is (12000,0.85). So, the function for the domain over [12000, 38000] is

y-0.85 = -0.00001(x-12000)

y =  -0.00001x + 0.97

c)

The cost per unit at the production level of 19,000 is 0.78.

Substitute x=19000 in the above equation, to find the cost per unit at the production level of 19,000.

y = -0.00001(19000) + 0.97

y = 0.78

Thus the cost per unit at the production level of 19,000 is 0.78.

In the diagram below of triangle BCD, E is the midpoint of BD and Fis
the midpoint of CD. If EF = -9x + 82, and BC = 80 - 6x, what is
the measure of BC?

Answers

The measure of BC is 48x - 168.

In the given diagram of triangle BCD, we are told that E is the midpoint of BD and F is the midpoint of CD. Let's denote the measure of BC as y.

Since E is the midpoint of BD, we can say that BE = ED. Similarly, F is the midpoint of CD, so CF = FD.

Using the information given, we can write the equation EF = -9x + 82. Since F is the midpoint of CD, we can substitute FD for EF, so FD = -9x + 82.

Also, we know that BC = 80 - 6x.

In triangle BCD, we can write the equation BC = BE + EF + FD.

Substituting the given values, we have:

80 - 6x = (BE) + (-9x + 82) + (-9x + 82).

Simplifying the equation:

80 - 6x = BE - 9x + 82 - 9x + 82.

Combining like terms:

80 - 6x = BE - 18x + 164.

Moving the variables to one side and constants to the other side:

6x - BE + 18x = 164 - 80.

Combining like terms:

24x - BE = 84.

Rearranging the equation:

BE = 24x - 84.

Since E is the midpoint of BD, we can write:

BE = BD/2.

Substituting the value of BE:

BD/2 = 24x - 84.

Simplifying the equation:

BD = 48x - 168.

We are required to find the measure of BC, which is y. From the equation BC = BD, we have:

y = 48x - 168.

A ball will be thrown upward from a height of 20 meters above the ground, with an initial velocity of 15 meters per second. Its distance from the ground, d, is a function of the time in seconds since the ball was thrown, t. This function is graphed below. How many seconds after the ball is thrown will it be 20 meters from the ground again ?

Answers

From the graph, we can calculate that 6 seconds after the ball is thrown, it will be 20 meters from the ground again.

How do we calculate?

The equation is as follows:

d = d0 + v0 * t - (1/2) * g * t²

d =  distance from the ground

d0 = the initial height

v0 =  initial velocity

g  =  acceleration due to gravity = 9.8 m/s²

t=  time

20 = 20 + 15 * t - (1/2) * 9.8 * t^2

We simplify as follows:

0 = -4.9 * t² + 15 * t

We then go ahead to solve  this quadratic equation to find the values of t when the ball is 20 meters from the ground again.

t * (-4.9t + 15) = 0

t = 0 or

-4.9t + 15 = 0.

-4.9t + 15 = 0

-4.9t = -15

Answers

The angle the vector v, that has components of 9,6 makes with the x- axis is 33.7°

What is the angle of a vector?

The angle of a vector with x and y components (x,y) is given by

Ф = tan⁻¹(y/x)

Given that vector v has components of 9,6. To determine the angle, Ф, in degrees , that vector v makes with the x-axis, we proceed as follows.

Answers

A. A table of values and graph of the function is shown below.

B. The object would hit the ground at approximately 8.963 seconds.

How to create a table of values and graph the function?

Based on the information provided, we can logically deduce that the height (s) in meters, of this object above the​ ground is related to time by the following quadratic function:

s(t) = -4.9t² +39.2t + 42.3

When t = 0, s(t) is given by;

s(0) = -4.9(0)² +39.2(0) + 42.3

s(0) = 42.3

When t = 1, s(t) is given by;

s(1) = -4.9(1)² +39.2(1) + 42.3

s(1) = 76.6

When t = 2, s(t) is given by;

s(2) = -4.9(2)² +39.2(2) + 42.3

s(2) = 101.1

Therefore, the table can be created as follows;

Time (t)     Height s(t)

0                  43.3

1                   76.6

2                  101.1

3                  115.8

4                  120.7

5                  115.8

Generally speaking, the height of this object would be equal to zero (0) when it hits the ground. By critically observing the graph (see attachment), we can logically deduce that the object would hit the ground at approximately 8.963 seconds.

If the events A and B are mutually exclusive, meaning they cannot occur simultaneously, then the probability of both events occurring together is zero. In this case, the formula simplifies to P(A or B) = P(A) + P(B).

The probability that either event A or event B will occur can be calculated using the addition rule of probability. According to this rule, the probability of either event A or event B occurring is equal to the sum of the individual probabilities of each event minus the probability of both events occurring together.

In other words, P(A or B) = P(A) + P(B) - P(A and B)



However, if the events A and B are not mutually exclusive, then the probability of both events occurring together needs to be subtracted from the sum of their individual probabilities to avoid double-counting.

The carrying capacity of a drain pipe is directly proportional to the area of its cross- section. If a cylindrical drain pipe can carry 36 litres per second, determine the percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second.​

Answers

Step-by-step explanation:

Let's start by using the formula for the volume of a cylinder:

V = πr^2h

where V is the volume of the cylinder, r is the radius of the cylinder, h is the height of the cylinder, and π is a mathematical constant (approximately equal to 3.14).

Since we are dealing with a drain pipe, we can assume that the height of the cylinder is fixed and does not change. Therefore, we can rewrite the formula as:

V = πr^2h = Ah

where A is the cross-sectional area of the cylinder.

Now, let's use the given information that the drain pipe can carry 36 litres per second. We know that the volume of water that passes through the pipe in one second is equal to 36 litres. We can therefore write:

36 = Ahv

where v is the velocity of the water flowing through the pipe. Since we are assuming that the height of the cylinder is fixed, we can simplify this equation to:

36 = Av

Now we need to determine the percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second. Let's call the new diameter d2 and the old diameter d1. We can set up a proportion to solve for d2:

A1/A2 = d1^2/d2^2

We know that A1 and A2 are proportional to the volumes of water the pipe can carry, so we can write:

A1/A2 = 36/60

Simplifying this equation, we get:

A1/A2 = 3/5

Substituting in the formula for the cross-sectional area of a cylinder, we get:

πd1^2/4 / πd2^2/4 = 3/5

Simplifying further, we get:

d1^2/d2^2 = 3/5

Taking the square root of both sides, we get:

d1/d2 = sqrt(3/5)

Now we can solve for d2:

d2 = d1 / sqrt(3/5)

We want to know the percentage increase in the diameter, which we can find using the formula:

% Increase = (New Value - Old Value) / Old Value x 100%

Substituting in our values, we get:

% Increase = (d1 / sqrt(3/5) - d1) / d1 x 100%

Simplifying, we get:

% Increase = (1 / sqrt(3/5) - 1) x 100%

Using a calculator, we get:

% Increase ≈ 34.64%

Therefore, the percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second is approximately 34.64%.

[(3/4) is to -9]

Cross-multiplying:

x * (3/4) = (3/4) * (-9)

Simplifying:

(3/4) * x = -27/4

To solve for x, we can multiply both sides of the equation by the reciprocal of (3/4), which is 4/3:

(4/3) * [(3/4) * x] = (4/3) * (-27/4)

Simplifying:

x = -9

The value of all the expression which have x = 5 asymptotes are,

⇒ g (x) = 3 log (x - 5)

⇒ g (x) = log₁₀ (- x + 5) -  4

⇒ f (x) = (3x + 20) / (x - 5)

We have to given that,

All the expressions are,

⇒ g (x) = 3 log (x - 5)

⇒ f (x) = √(x - 5) + 2

⇒ h (x)= eˣ⁻⁵

⇒ g (x) = log₁₀ (- x + 5) -  4

⇒ h (x) = - ∛(x - 5) + 1

⇒ f (x) = (3x + 20) / (x - 5)

Now, We can check all the expressions for which have x = 5 asymptotes.

Hence, We can substitute x = 5 in each expression and check all expression as which are not defined at x = 5,

⇒ g (x) = 3 log (x - 5)

Substitute x = 5;

⇒ g (x) = 3 log (5 - 5)

⇒ g (x) = 3 log (0)

Which is undefined.

⇒ f (x) = √(x - 5) + 2

Substitute x = 5;

⇒ f (x) = √(5 - 5) + 2

⇒ f (x) = 2

Which is defined.

⇒ h (x)= eˣ⁻⁵

Substitute x = 5;

⇒ h (x)= e⁻⁵

Which is defined.

⇒ g (x) = log₁₀ (- x + 5) -  4

Substitute x = 5;

⇒ g (x) = log₁₀ (- 5 + 5) -  4

⇒ g (x) = log₁₀ (0) -  4

Which is undefined.

⇒ h (x) = - ∛(x - 5) + 1

Substitute x = 5;

⇒ h (x) = - ∛(5 - 5) + 1

⇒ h (x) =  1

Which is defined.

⇒ f (x) = (3x + 20) / (x - 5)

Substitute x = 5;

⇒ f (x) = (3x + 20) / (5 - 5)

[tex]f(x)=\sqrt[3]{2x-1}[/tex]

Answers

The function [tex]f(x) = \sqrt[3]{2x-1}[/tex] is a cubic root function with a linear transformation applied.

How to solve

The expression inside the root, 2x-1, is a linear function that scales and shifts the input x. The cubic root function then takes the cube root of the result.

This function is defined for all real numbers x, as the cubic root can be calculated for any real number.

Its graph is a transformed version of the standard cubic root function, skewed and shifted depending on the coefficients in the linear function. The function increases monotonically as x increases, and it is continuous and differentiable everywhere.

The non-linear graph of the function y = -(x - 1)² + 1. is given by the image presented at the end of the answer.

When a function is positive and when it is negative?

We have to look at the graph of the function relative to the x-axis, as follows:

A function is positive when it is above the x-axis.A function is negative when it is below the x-axis.

The function has a maximum point at (1,1), meaning that:

The function is increasing for x > 1.The function is decreasing for x < 1.

Considering the end behavior of the function, that it goes to negative infinity at both tails of the graph, a function that satisfies these features is given as follows:

y = -(x - 1)² + 1.

Line AB is congruent to line CD , proved.

What is the proof for line AB and CD?

The proof that line AB is congruent to line CD is determined as follows;

If line AB ≅ CD, then will have the following to be true;

m∠BAE = m∠DCEm∠ABE = m∠CDEm∠AEB = m∠DEC

Let angle A = x

The value of angle C will be equal to x (alternate angles are equal)

Let angle B = y

The value of angle D will be equal to y (alternate angles are equal)

Let angle m∠AEB = z

The value of m∠DEC will be equal to z (vertical opposite angles are equal).

So line AB is congruent to line CD , proved.

A tour from the Zoo to the Park and the Port and back to the Zoo is 15 km long. How long is the shortest tour from A to B to Cand back to A? (A) 18 km (B) 20 km (C) 25 km (D) 35 km (6) 50 km​

Answers

The shortest tour from A to B to C and back to A is 50 km.

We have,

A to Zoo and Port and back to A: 10 km

B to Park and Zoo and back to B: 12 km

C to Port and Park and back to C: 13 km

Zoo to Park and Port and back to Zoo: 15 km

To calculate the shortest tour from A to B to C and back to A, we can add up the distances between each pair of stations:

A to Zoo and Port and back to A (10 km)

Zoo to Park and Port and back to Zoo (15 km)

B to Park and Zoo and back to B (12 km)

C to Port and Park and back to C (13 km)

So, Total distance: 10 + 15 + 12 + 13 = 50 km

Therefore, the shortest tour from A to B to C and back to A is 50 km.

C. In the context of the problem, a meaningful domain is {x | x ≤ 0} and a meaningful range is {y | y ≥ 0}.

How to construct and plot the function on a graph?

In this exercise, we would plot the illumination on the y-axis (y-coordinates) of a graph while the square of the distance would be plotted on the x-axis (x-coordinate) of a graph on a coordinate plane.

Part B.

The illumination in foot-candles that this object would receive at a distance of 20-feet from the light source can be calculated by substituting the value of d, which is 20 feet into the function as follows;

I(d) = 4500/d²

I(20) = 4500/20²

I(20) = 4500/400

I(20) = 11.25 foot-candles.

Part C.

By critically observing the graph shown in the image attached below, we can reasonably and logically deduce the following domain and range:

Domain = [-∞, 0] ∪ [0, ∞] or {x | x ≤ 0}.

Range = [0, ∞] or {y | y ≥ 0}
