In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their components. (You must first specify a coordinate system in order to find the components of each arrow.) This problem gives you some practice with the components. Let vectors A rightarrow = (1,0, -3), rightarrow = (-2,5,1), and C rightarrow = (3,1,1). Calculate the following, and express your answers as ordered triplets of values separated by commas.

Based on the numbers being divided, the number of significant digits that the quotient should have is 4 significant digits.

The number of significant digits from a quotient where numbers divided each other should be the significant digits in the number with the smaller number of significant digits.

The number with the lower significant digits here is 2.058 × 10^9.

In this number, there are 4 significant digits because 0 is between non zero numbers.

Considering the definition of an equation and the way to solve it, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

First, you define the variable "m" as the number of miles rented from a truck to a company in a day. You know that:

So the price of each company is:

If the rental costs for Company A and Company B are the same, the equation in this case is:

Price of company A= Price of company B

130 + 0.30m= 70 + 0.60m

Solving:

130 - 70= 0.60m - 0.30m

60= 0.30m

60÷0.30= m

200= m

In summary, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. the curve at the top is more dispersed and has a greater standard deviation than the curve at the bottom, which is more concentrated around the mean and has a lower standard deviation.

Step-by-step explanation:

Hannah had run 6 complete laps and is running the 7th lap when she surpasses the athlete Kara.

An athlete (sometimes known as a sportsman or sportswoman) is a person who participates in one or more sports that require physical stamina, speed, or strength.

Professional and amateur athletes both exist. The majority of elite athletes have extremely well-developed bodies because to rigorous physical training, stringent exercise, and a tight food regimen.

Isotonic exercisers had a greater mean left ventricular end-diastolic capacity and are less prone to experience depression. Athletes are far more prone than the general public to go to massage parlors and pay for the services of massotherapists and masseurs due to their demanding physical activity. Athletes whose sport favors endurance over strength typically consume less calories than other athletes.

Calculations:

Total length of the race (L) = 5000 m

Time taken by Kara (tk) = 17.9 min = 1074 s

Kara's speed (vk) = L/tk = 5000/1074 m/s

Time taken by Hannah (th) = 15.3 min = 918 s

Hannah's speed (vh) = L/th = 5000/918 m/s

Let the number of laps Hannah had run when she passes Kara be n

Distance travelled by Hannah in this time = n*400 = 400n meters

Time taken by Hannah to run n laps = 400n/(5000/918)=367200n/5000=73.44n

Distance travelled by Kara in this time = (n-1)*400 = 400n - 400 meters

Time taken by Kara to run (n-1) laps = (400n-400)/(5000*1074)=(429600n-429600)/5000=85.92n-85.92

= 85.92n - 85.92 = 73.44n

= 12.48n = 85.92

= n = 6.88

The lengths of the three sides of the triangular lot are: 100 feet, 200 feet and 400 feet.

What is a triangle and its perimeter?

A triangle is a polygon with three edges and three vertices.

Given:

To find: All the sides of the triangular lot.

FInding:

Let the shortest side of the triangular lot be 'x'.

Then, according to the question, one side of the triangular lot = 100 + x and other = 300 + x

As perimeter of a triangle = sum of all the sides,

=> 1300 = x + 100 + x + 300 + x

=> 1300 - 400 = 3x

=> 900 = 3x

=> 300 = x

Hence, the shortest side = 100 feet, a longer side = 200 feet, the longest side = 400 feet for the given triangular lot.

If two marbles are randomly chosen from the bag contains 22 yellow marbles and 11 teal marbles, then the probability that the both marbles are teal is [tex]\frac{10}{99}[/tex]

Given,

The number of yellow marbles = 22

Number of teal marbles = 11

Total number of marbles = 22+11= 33 marbles

Then two marbles are chosen randomly

We know,

The probability = Number of favorable outcomes/ Total outcomes

Probability that first marble is teal =[tex]\frac{11}{33}[/tex]=[tex]\frac{1}{3}[/tex]

Probability that second marble is teal =[tex]\frac{10}{33}[/tex]

The polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

Suppose the cost in dollars of producing x model kits is given by the polynomial 500,000 + 2x and the revenue generated from sales is given by the polynomial 30x - 0.00005 x².

The profit = revenue - cost

The profit = (30x - 0.00005 x²) - (500,000 + 2x)

The profit = 30x - 0.00005 x² - 500,000 - 2x

The profit = 28x - 500,000 - 0.00005 x²

Plug x = 300,000 in the profit expression.

The profit = 3400000

Thus, the polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Relationships that have a uniform or constant rate are said to be proportional relationships. Because it does not employ a uniform rate, the price of food does not follow a proportional connection.

The missing table looks like this:

Bag     cost

30        89

First, we calculate the slope (m) of the table using:

(x₁ y₁) = (0,0)

(x₂ y₂) = (5,17.5)

m₁=(y₂-y₁)/(x₂ -x₁)

m₁=(17.5-0)/(5-0)

m₁=3.5

The slope for the following points

(x₁ y₁) = (0,0)

(x₂ y₂) = (30,89)

m₂=(y₂-y₁)/(x₂ -x₁)

m₂=(89-0)/(30-0)

m₂=2.97

Where:

If we know that C = $ 2 600, C' = $ 37 000 and t = 8, then the value of the car at the end of the fifth is:
