Find the component form of vector v with initial point (-6,2) and terminal point (7,-3).
Answers
The component form of vector v with initial point (-6,2) and terminal point (7,-3) is (13,-5).
What is component form of vector?The component form of a vector is represented as x, y >, where x denotes the direction of travel (right or left) and y denotes the direction of travel (up or down) of the vector. Any two-dimensional vector may be conceived of as exerting influence in two separate directions. In other words, it can be considered to have two pieces. Components are the individual pieces that make up a two-dimensional vector. A vector's elements show how that vector will act in a specific direction.
Here,
initial point A=(-6,2)
terminal point B=(7,-3).
AB=(Bx-Ax, By-Ay)
=(7-(-6), -3-2)
= (13, -5)
The component form of the vector v with the starting points (-6, 2) and terminal points (7, -3) is (13,-5).

Which set of numbers best defines the domain of f(x)?A) IntegersB) Positive real numbersC) Positive rational numbersD) Whole numbers
Answers
Recall that the domain of a function is the set of numbers to which the function is defined. That is, if you replace the value of the independant variable (normally represented as x), then the function will give another number as a result.
In this case, we are given the function 400+13x. Since x is the independant variable, to determine the domain we must think on what possible values the variable x can take. Since in this case x represents the number of products made, it is impossible that it takes negative values, since in real life you can't produce negative amounts of products.
So far, we know that x should be greater or equal to zero. Once again, in this context, it doesn't make sense that, for example, x=7.8, since this would mean that 7.8 number of products were made. Since x represents the number of products made, it can only take values as x=0,x=1, x=2, x=3 and so on.
This set receives the name of whole numbers.

people with type o-negative blood are universal donors. that is, any patient can receive a transfusion of o-negative blood. only 7.2% of the american population have o-negative blood. if we choose 10 americans at random who gave blood, what is the probability that at least 1 of them is a universal donor?
Answers
The probability that any given person is a universal donor is 7.2%. This means that the probability that a person is not a universal donor is 92.8%.This indicates that there is a 0.65 percent chance that at least 1 out of every 10 randomly selected individuals is a universal donor.
Now, if we choose 10 people at random, we can use the binomial distribution to calculate the probability that at least 1 of them is a universal donor. The binomial distribution tells us that the probability of getting exactly k successes in n trials is:
P(k; n, p) = (n choose k) p^k (1-p)^(n-k)
where n is the number of trials, p is the probability of success on a single trial, and k is the number of successes.
plugging in our values, we get:
P(1; 10, 0.072) = (10 choose 1) (0.072)^1 (1-0.072)^9
P(1; 10, 0.072) = 10(0.072) (0.928)^9
P(1; 10, 0.072) = 0.65
This means that the probability that at least 1 out of 10 people chosen at random is a universal donor is 0.65.

Which image shows triangle A dilated by a scale factor of 2 with a center at the origin?
Answers
The triangle ABC undergoes a dilation of scale factor 2 centered at the origin.
Dilation About the Origin
Given a point P(x,y), its dilation about the origin by a scale factor of k maps the point to a point P'(kx,ky).
If we are given the dilated point, then we can find the original point by dividing by the scale factor.
Triangle ABC was dilated by a scale factor of 2 about the origin mapping it to triangle A'B'C' with vertices A'(-4,4), B'(-4,6), and C(2,4).
The coordinates of triangle ABC are:
A=(-4/2,4/2) = (-2,2)
B=(-4/2,6/2) = (-2,3)
C=(2/2,4/2) = (1,2)
The coordinates of ABC are respectively (-2,2), (-2,3), and (1,2).
Hence the answer is the triangle ABC undergoes a dilation of scale factor 2 centered at the origin.

Playing basketball carries a met value of 8 and you weigh 130lbs or roughly 59kg, approximately how many calories per minute would you burn?.
Answers
The average person burns 575-775 calories per hour in a game of basketball. If they are shooting baskets, they will burn 325-450 calories per hour.
What is Calories?
Calories are a measure of energy. Two main definitions of "calorie" are frequently used due to historical factors. The amount of heat required to increase the temperature of one kilogramme of water by one degree Celsius was the original definition of the large calorie, food calorie, as well as kilogramme calorie (or one kelvin). The amount of heat required to produce the same increase in one gramme of water was known as the small calorie or gramme calorie. As a result, 1000 small calories are equal to 1 large calorie.
How many calories do basketball players burn?
Calories expended per minute equal (MET x body weight in kg x 3.5) / 200
"MET" is a unit of measurement for the energy expended during a given period of physical exercise. The chart above shows the MET for each activity.The energy required to perform a task with a MET of 1 is roughly equivalent to what it would take to sit stationary at room temperature without actively digesting food.When compared to a task with a MET of 1, one with a MET of 2 requires twice as much energy. Ten times as much energy is expended on a work with a MET of 10 as on one with a MET of 1.Hence, the average person burns 575-775 calories per hour in a game of basketball. If they are shooting baskets, they will burn 325-450 calories per hour.

By using division of decimal numbers, it is obtained that cost of 1 pound of coffee is $8.99
What is decimal number and division?
Decimal numbers are those numbers which consist of an integer part and a fractional part.
Decimal are of two types-
Terminating decimals are those decimals which has finite number of figures after decimal point
Non terminating decimals are those decimals which has infinite number of figures after decimal point.
Division is the process by which value of single unit can be calculated from the value of multiple unit
The number which is divided is the dividend, the number by which dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.
There is a well known formula in division
Divisor x Quotient + Remainder = Dividend
Here, division of decimal will be used
Cost of 5 pounds of coffee = $44.95
Cost of 1 pound of coffee = $[tex]\frac{44.95}{5}\\[/tex]
= $8.99
Cost of 8 pounds of coffee = $71.92
Cost of 1 pound of coffee = $[tex]\frac{71.92}{8}\\[/tex]
= $8.99
Cost of 14 pounds of coffee = $125.86
Cost of 1 pound of coffee = $[tex]\frac{125.86}{14}\\[/tex]
= $8.99
Cost of 20 pounds of coffee = $179.80
Cost of 1 pound of coffee = $[tex]\frac{179.80}{20}\\[/tex]
= $8.99
So cost of 1 pound of coffee = 8.99
