Find the supplementary angles formed by the line y=3x-5 and the line 4x-3y=1

Answers

Answer 1
Answer:

= 55.3 degrees

Step-by-step explanation:

To find the supplementary angles formed by two lines, we need to find the angles formed by each line and then subtract the sum of those angles from 180 degrees.

Let's begin by finding the slope of each line. The first line y=3x-5 is in slope-intercept form,
where the slope is the coefficient of x, which is 3.

The second line 4x-3y=1 can be rearranged to slope-intercept form by solving for y:

4x - 3y = 1
-3y = -4x + 1
y = (4/3)x - 1/3

The slope of the second line is 4/3.

Next, we can find the angle formed by each line with the x-axis using the formula:

angle = arctan(slope)

where arctan is the inverse tangent function. We can use a calculator to find the angle in degrees.

For the first line, angle = arctan(3) ≈ 71.57 degrees.

For the second line, angle = arctan(4/3) ≈ 53.13 degrees.

To find the supplementary angles, we subtract the sum of these angles from 180 degrees:

supplementary angle = 180 - (71.57 + 53.13) = 55.3 degrees.

Therefore, the supplementary angles formed by the line y=3x-5 and the line 4x-3y=1 are 55.3 degrees.

how would i find an equation algebraicaly when my points are (0,3) to (5,3) and would what would be my domain and range? 20 points!!

Answers

Answer:

Step-by-step explanation:

To find the equation of a line when you have two points, you can use the point-slope formula. Here's how to do it:

1. Find the slope of the line using the two points:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, 3) and (x2, y2) = (5, 3)

slope = (3 - 3) / (5 - 0) = 0/5 = 0

2. Use the point-slope formula to find the equation of the line:

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is one of the points on the line. Using (0, 3) as the point, we get:

y - 3 = 0(x - 0) or y = 3

So the equation of the line is y = 3, a horizontal line passing through y = 3.

The domain of this equation is all real numbers, since x can take on any value and y will always be 3.

The range of this equation is a single value, y = 3, since the line is horizontal and every point on the line has the same y value of 3.

The triangle below is equilateral. Find the length of the side x to the nearest tenth.

Answers

To the nearest tenth, the length of each side of the equilateral triangle is roughly [tex]10(\sqrt{(3) - 1)[/tex].

What characteristics define equilateral?

An equilateral triangle has the following three characteristics: identical lengths on all three sides. The three angles are identical. Three symmetry lines may be seen in the figure.

All of the triangle's sides are equal in length since it is equilateral. Call this length "s" for short.

The distance from vertex A to side x, measured in altitude, is equal to the length of side x. Call the intersection of the altitude and side x "P" for short.

The length of AP is [tex](s/2) * \sqrt{}[/tex] because we know that the altitude from vertex A creates a triangle with sides of 30-60-90. (3).

Since side BP is half the length of side AB, we also know that its length is (s/2).

As a result, x's length equals the product of AP and BP:

x = AP + BP

= (s/2) * [tex]\sqrt{(3) + (s/2)[/tex]

= [tex](s/2)(\sqrt{(3) + 1)[/tex]

We are told that x equals 10. We may put the formula we discovered for x equal to 10 and do the following calculation to find s:

[tex](s/2)(\sqrt{(3) + 1)[/tex] = 10

The result of multiplying both sides by two is:

[tex]s(\sqrt{(3) + 1) = 20[/tex]

When you divide both sides by [tex](\sqrt{(3) + 1)[/tex], you get:

[tex]s = 20/(\sqrt{3) + 1)[/tex]

The result of multiplying the numerator and denominator by the conjugate of [tex](\sqrt{(3) + 1), (\sqrt{(3) - 1)[/tex], is as follows:

s = [tex]20(\sqrt{3) - 1)/(3 - 1)[/tex]

= [tex]10(\sqrt{(3) - 1[/tex]

As a result, to the nearest tenth, the length of each side of the equilateral triangle is about [tex]10(\sqrt{(3) - 1[/tex].

if customer interarrival times are exponentially distributed with rate 6 customers per hour, then to simulate the minutes between customer arrives in excel, one would use: group of answer choices

Answers

To simulate the minutes between customer arrivals in Excel, one would use the Exponential distribution function in Excel.

This function is part of the Statistical functions category and can be found under the "Statistical" tab in Excel.

An exponential distribution is a probability distribution that describes the time between events in a Poisson process, where events occur continuously and independently at a constant average rate.

The Exponential distribution function in Excel takes two arguments: Lambda and x.

Lambda is the rate parameter, which describes the average number of events per unit of time.

In this case, the rate is 6 customers per hour, so Lambda would be equal to 6.

X is the time interval, and in this case, it would be the time between customer arrivals in minutes.

Therefore, to simulate the minutes between customer arrivals, one would use the following formula in Excel: =EXPON.DIST(x/60,1/6,TRUE)

The "x/60" part of the formula is used to convert the time interval from minutes to hours, as the rate is given in customers per hour.

The "1/6" part of the formula is used to set the Lambda value to 6.

The "TRUE" part of the formula is used to specify that we want the cumulative distribution function (CDF), which gives the probability that the time between events is less than or equal to x.

To simulate the minutes between customer arrivals in Excel, we would use the Exponential distribution function with Lambda = 6 and x being the time interval between customer arrivals in minutes.

The formula would be = EXPON.DIST(x/60,1/6,TRUE).

When we say that liquid water is unstable on Mars, we mean that

Answers

Therefore, liquid water is considered to be unstable on Mars due to the cold temperatures, low atmospheric pressure, and the UV radiation. All of these environmental factors make it difficult for liquid water to persist.

Liquid water is unstable on Mars due to its cold, dry environment. Because the atmospheric pressure is too low to hold liquid water, the water on Mars quickly evaporates, sublimates, and/or is broken down by the ultraviolet radiation in the atmosphere.
The average temperature of the surface of Mars is −63 °C, which is well below the freezing point of water. Because of this, liquid water cannot exist on the surface of Mars. When temperatures are slightly higher, water can exist as a liquid, but it cannot stay in this state for very long.
The atmosphere on Mars also does not contain enough pressure to sustain liquid water. Even when water vapor is present, it will quickly evaporate in the low-pressure environment. Additionally, the UV radiation in the Martian atmosphere will break down water molecules quickly.

Find the surface area of the solid. Round your answer to the nearest tenth
if necessary.

Answers

Area of the solid composite shape with triangle and rectangle is =832cm².

Define area of composite shapes?

The area of a composite shape can be determined by adding or subtracting its component pieces.

Hence, we can use two formulas:

Area of Composite Shape + Area of Composite Shape + Area of Basic Shape A (additive)

Basic Shape Area A, Basic Shape Area B, and Composite Shape Area (subtractive)

In the figure,

Dimensions of the triangle are height, h = 16cm and base, b = 12cm.

Area = 1/2 ×b ×h

= 1/2 × 16× 12

=96cm²

There are two triangles, so the total area = 96+ 96 = 192cm².

Now area of the rectangle = length × width

= 20 × 32

= 640cm².

Total area of the solid= 192 + 640 = 832cm².

the volume of the right cone below is 392\piπ units^3 3 . Find the value of xx.

Answers

The value of x is approximately 8.15.

To find the value of x, we need to use the formula for the volume of a cone, which is V = (1/3)πr^2h, where r is the

radius of the base and h is the height of the cone. We know that the volume of the cone below is 392π, so we can set

up the equation:

[tex]392π = (1/3)πx^2h[/tex]

Simplifying, we can divide both sides by π and multiply by 3 to get:

[tex]1176 = x^2h[/tex]

Using the Pythagorean theorem, we can relate the height, radius, and slant height of the cone:

[tex]h^2 + r^2 = x^2[/tex]

Since the cone is a right cone, we know that the radius is half of the diameter, which is equal to x/2. Substituting this in,

we get:

[tex]h^2 + (x/2)^2 = x^2[/tex]

Simplifying:

[tex]h^2 = x^2 - (x/2)^2

h^2 = 3x^2/4[/tex]

Now we can substitute this expression for [tex]h^2[/tex] into our equation for the volume:

[tex]1176 = x^2(3x^2/4)[/tex]

Simplifying again:

[tex]1176 = 3x^4/4[/tex]

[tex]1568 = 3x^4[/tex]

[tex]x^4 = 1568/3[/tex]

Taking the fourth root of both sides:

[tex]x = (1568/3)^(1/4)[/tex]

The Perimeter of the parallelogram whose vertices are given by the coordinates (3 ,6), (-5, 6), (6, -1), (-2, -1) is: 16 + 2√(58)

What is the explanation for the above response?

To find the perimeter of the parallelogram, we need to find the distance between each pair of adjacent vertices and add them up.

First, let's find the distance between (3, 6) and (-5, 6). This is simply the difference between their x-coordinates, which is 3 - (-5) = 8.

Next, let's find the distance between (-5, 6) and (-2, -1). To do this, we need to find the difference between their x-coordinates and their y-coordinates, and then use the Pythagorean theorem. The difference in x-coordinates is -5 - (-2) = -3, and the difference in y-coordinates is 6 - (-1) = 7. So the distance between these two points is √((-3)^2 + 7^2) = √(58).

We can use the same method to find the distance between (6, -1) and (3, 6), which is also √(58).

Finally, we need to find the distance between (6, -1) and (-2, -1), which is simply the difference between their x-coordinates, which is 6 - (-2) = 8.

Adding up all these distances, we get 8 + √(58) + √(58) + 8 = 16 + 2√(58).

So the exact perimeter of the parallelogram is 16 + 2√(58)

What is the relationship between the mean and median? a. the mean is approximately the same as the median. b. the mean is greater than the median. c. the mean is less than the median.

Answers

The relationship between the mean and median depends on the shape of the distribution of the data, therefore correct options are

(a) The mean is approximately the same as the median

(b) The mean is greater than the median

(c)  The mean is less than the median.

The relationship between the mean and the median depends on the shape of the distribution of the data. In a symmetric distribution, the mean and median will be approximately the same. In a skewed distribution, the mean will be pulled in the direction of the skew, and the median will be a better representation of the "typical" value.

If the distribution is symmetrical (i.e., evenly distributed around the center), the mean and median will be approximately the same.

If the distribution is positively skewed (i.e., has a long tail on the right side), the mean will be greater than the median.

If the distribution is negatively skewed (i.e., has a long tail on the left side), the mean will be less than the median.

Therefore, correct options are

(a) The mean is approximately the same as the median

(b) The mean is greater than the median

(c)  The mean is less than the median.

ten percent of computer parts produced by a certain supplier are defective. what is the probability that a sample of 10 parts contains more than 3 defective ones?

Answers

The probability of a sample of 10 parts containing more than 3 defective ones is approximately 0.026.

We can use the binomial distribution to calculate the probability of getting more than 3 defective parts in a sample of 10 parts. Let X be the number of defective parts in the sample. Then X follows a binomial distribution with parameters n=10 and p=0.1, where n is the sample size and p is the probability of a part being defective.

We can calculate the probability of getting more than 3 defective parts is:

P(X > 3) = 1 - P(X ≤ 3) = 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3)]

Next, we can find that:

P(X > 3) = 0.026

Mark has a key ring with 10 similar keys. There are 3 gym locker keys, 2 car keys, I door key, and 4 toolbox keys. If Mark selects one key without looking, what is the probability he
selects a car key or door key?

Answers

The probability that Mark selects a car key or door key from the key ring is 0.3 or 30%.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability theory provides a framework for understanding random events and the laws of chance, and it is an important tool for modeling and simulating complex systems.

Calculating the probability that he selects a car key or door key :

In this context, we are asked to find the probability of Mark selecting a car key or door key from the key ring. To calculate this probability, we need to first determine the total number of keys on the key ring and then count the number of car keys and door keys.

Total number of keys = 10

Number of car keys = 2

Number of door keys = 1

The probability of selecting a car key or door key can be found by adding the probability of selecting a car key to the probability of selecting a door key. Since there is only one door key and two car keys, the probability of selecting a car key is higher, and we can simplify the calculation by finding the probability of selecting a car key and then adding the probability of selecting a door key that hasn't already been selected.

Probability of selecting a car key = 2/10 = 0.2

Probability of selecting a door key = 1/9 (since one key has already been selected) = 0.1111...

Therefore, the probability of Mark selecting a car key or door key from the key ring is 0.2 + 0.1111... ≈ 0.3 or 30%.

Find the areas of the figures whose vertices are
(a) (0,0), (3,7), (5,1)
(c) (-4,2), (0,-8), (5,11)
(e) (-2,-4), (3,1), (-1,5), (6,-3)
(b) (-1,-2), (-2,3), (4,-4)

Answers

(a) The area of the triangle is 16 square units.

(b) The area of the triangle is 54 square units.

(c) the area of the quadrilateral is 20 square units.

(d) The area of the triangle is 12.5 square units.

What is the area of the figures?

(a) To find the area of the triangle with vertices (0,0), (3,7), and (5,1), we can use the formula:

A = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |

Plugging in the values, we get:

A = 1/2 | 0(7 - 1) + 3(1 - 0) + 5(0 - 7) |

= 1/2 | 0 + 3 - 35 |

= 1/2 |-32|

= 16

(b) To find the area of the triangle with vertices (-4,2), (0,-8), and (5,11), we can again use the same formula:

A = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |

Plugging in the values, we get:

A = 1/2 | (-4)(-8 - 11) + (0)(11 - 2) + (5)(2 - (-8)) |

= 1/2 | 108 |

= 54

(c) To find the area of the quadrilateral with vertices (-2,-4), (3,1), (-1,5), and (6,-3), we can divide it into two triangles and find the area of each triangle.

We can use the formula for the area of a triangle:

A = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |

For the triangle with vertices (-2,-4), (3,1), and (-1,5), we get:

A1 = 1/2 | (-2)(1 - 5) + (3)(5 + 4) + (-1)(-4 - 1) |

= 1/2 | (-8 + 35 + 5) |

= 16

For the triangle with vertices (3,1), (-1,5), and (6,-3), we get:

A2 = 1/2 | (3)(5 + 3) + (-1)(-3 - 1) + (6)(1 - 5) |

= 1/2 | (24 + 4 - 20) |

= 4

Therefore, the area of the quadrilateral is:

A = A1 + A2

= 16 + 4

= 20 square units

(d) To find the area of the triangle with vertices (-1,-2), (-2,3), and (4,-4), we can use the same formula:

A = 1/2 | x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2) |

Plugging in the values, we get:

A = 1/2 | (-1)(3 + 4) + (-2)(-4 + 2) + (4)(-2 - 3) |

= 1/2 | (-7 - 4 - 14) |

= 12.5

R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}

Find the values of a and b that complete the mapping diagram.

Answers

what is diagram mapping?

An effective visual representation of a function or a mapping between two sets is a mapping diagram. It consists of two vertical columns, one of which represents the domain set items and the other of which represents the range set elements. The items in the range set that match to those in the domain set are listed in the right column, and vice versa.

I assume you are given a mapping rule that relates elements in a set to other elements in another set, and you are asked to complete a mapping diagram based on this rule.

If the mapping rule is not specified, we cannot determine the values of a and b. However, assuming that the mapping rule is such that each element (x, y) in the set R is mapped to [tex](x + a, y + b)[/tex], we can complete the mapping diagram as follows:

The given set R is:

R = {(-3, -2), (-3, 0), (-1, 2), (1, 2)}

If we apply the mapping rule to each element in R, we get:

(-3, -2) → (-3 + a, -2 + b)

(-3, 0) → (-3 + a, 0 + b)

(-1, 2) → (-1 + a, 2 + b)

(1, 2) → (1 + a, 2 + b)

To complete the mapping diagram, we need to find the values of a and b such that each mapped element is in the set R. That is, we need to find a and b such that:

(-3 + a, -2 + b) ∈ R

(-3 + a, 0 + b) ∈ R

(-1 + a, 2 + b) ∈ R

(1 + a, 2 + b) ∈ R

Substituting the values of R into each of these equations, we get:

(-3 + a, -2 + b) = (-3, -2), which gives a = 0 and b = 0

(-3 + a, 0 + b) = (-3, 0), which gives a = 0 and b = 0

(-1 + a, 2 + b) = (-1, 2), which gives a = 0 and b = 0

(1 + a, 2 + b) = (1, 2), which gives a = 0 and b = 0

Therefore, the values of a and b that complete the mapping diagram are a = 0 and b = 0.
