Answer:
The point from which measurements are made. The point where all coordinate values are zero.
Step-by-step explanation:
In the Newtonian/Euclidean universe, the laws of geometry and physics are the same everywhere. Hence, in order to tell one place from another, we define a point of origin from which all coordinates are measured. Then, every point in space can be named in terms of its coordinates relative to the origin.

Talk of the Town is a cell phone provider. They charge by the month. The first month of service costs $72.99. The second month of service costs $101.44. The third month of service costs $129.89. Write an equation in the form of
y=c+d(x−1)
to represent this situation. Explain how you got your equation.
Answer:
[tex]y=72.99+28.45(x-1)[/tex]
Step-by-step explanation:
Linear Modeling
Some situations in real life are bound to be modeled as mathematical functions. A model allows scientists and analysts to take decisions based on predicted values coming from those models.
To construct them we usually take or measure values of the variables of interest and find the general equation of the model. In this case, we'll find the relation between the service costs (y) of a cell phone provider and the number of months (x).
There are three points available: ( 1 , 72.99 ) , ( 2 , 101.44 ) , ( 3 , 129.89 ) and we only need two to find a function of the form
[tex]y=c+d(x-1)[/tex]
We'll use the first two points and use the third point to verify the validity of the model. Let's plug in the first point:
[tex]72.99=c+d(1-1)[/tex]
Operating
[tex]72.99=c\\c=72.99[/tex]
Now for the second point
[tex]101.44=72.99+d(2-1)[/tex]
Operating and rearranging
[tex]d=101.44-72.99=28.45[/tex]
Our model is complete:
[tex]\boxed{y=72.99+28.45(x-1)}[/tex]
Let's check the third point ( 3 , 129.89 ) by plugging x=3
[tex]y=72.99+28.45(3-1)=72.99+56.9=129.89[/tex]
The point belongs to the function.
Final answer:
The cell phone provider's escalating monthly charges can be represented by a linear equation, demonstrating the initial cost plus the consistent monthly increase. The equation is y = 72.99 + 28.45(x - 1).
Explanation:
To find the equation representing the cell phone provider Talk of the Town, we observe the costs for the first three months: $72.99 for the first month, $101.44 for the second, and $129.89 for the third. The increase in cost from one month to the next is consistent, increasing by $28.45 each time. This situation can be expressed as a linear equation in the form y=c+d(x−1), where y is the total cost, c is the starting value, d is the difference per period, and x represents the month number.
To find c (the initial cost), we look at the first month's charge: $72.99. d, the monthly increase, is $28.45. Thus the equation for the total cost of service from Talk of the Town over x months is y = 72.99 + 28.45(x - 1). This equation accounts for the initial cost in the first month and the consistent monthly increase thereafter.

A train has 3 passenger cars and each car has 4 columns of seats and each column holds 40 passengers. If one of the cars has 15 people standing in addition to all of the sitting passengers, and the rest of the cars are full without anyone standing, how many passengers are on the train?
Answer:
There are a total of 495 people on the train
Step-by-step explanation:
Let's identify what we know:
1) The train has 3 passenger cars
2) Each passenger car has 4 columns, and each can accommodate 40 people.
3) All three passenger cars are full, but one of them has 15 additional people standing.
We can create a formula to model the problem:
x = ((3 x 4) x 40) + 15
x = the total number of passengers!
There are a total of 180 people sitting, and 15 additional people standing in one of the passengers cars, equaling a total of 495 passengers on the train.
The train has a total of 495 passengers.
Explanation:To calculate the number of passengers on the train, we first need to determine the seating capacity of each car. Since each car has 4 columns of seats and each column holds 40 passengers, each car can seat a total of 4 x 40 = 160 passengers.
Next, we need to account for the 15 people standing in one of the cars. This means that one car has 160 + 15 = 175 passengers.
Finally, since the rest of the cars are full without anyone standing, we can assume that the other two cars also have 160 passengers each. Therefore, the total number of passengers on the train is 175 + 160 + 160 = 495.

Answer:
The lines blue and green are perpendicular
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
step 1
Find the slope of the blue line
we have the points
(-1,-3) and (0,3)
substitute
[tex]m=\frac{3+3}{0+1}[/tex]
[tex]m=\frac{6}{1}=6[/tex]
step 2
Find the slope of the red line
we have the points
(3,-3) and (4,2)
substitute
[tex]m=\frac{2+3}{4-3}[/tex]
[tex]m=\frac{5}{1}=5[/tex]
step 3
Find the slope of the green line
we have the points
(-4,-1) and (2,-2)
substitute
[tex]m=\frac{-2+1}{2+4}[/tex]
[tex]m=-\frac{1}{6}[/tex]
step 4
Compare the slopes
Blue line ----> [tex]m=6[/tex]
Red line ----. [tex]m=5[/tex]
Green line ---> [tex]m=-\frac{1}{6}[/tex]
so
The slope of the blue line and the green line are opposite reciprocal ( their product is equal to -1)
therefore
The lines blue and green are perpendicular
On a planet far far away from Earth, IQ of the ruling species is normally distributed with a mean of 118 and a standard deviation of 18. Suppose one individual is randomly chosen. Let X = IQ of an individual.
b. Find the probability that a randomly selected person's IQ is over 115.
Answer:
0.5675
Step-by-step explanation:
We have that, the IQ of the ruling species is normally distributed with a mean of 118 and a standard deviation of 18.
We want to find the probability that a randomly selected person's IQ is over 115.
We need to find the z-score of 115
using
[tex]z = \frac{x - \mu}{ \sigma} [/tex]
We substitute x=115 to get:
[tex]z = \frac{115 - 118}{18} [/tex]
This implies that:
[tex]z = \frac{ - 3}{18} = - \frac{1}{6} = - 0.17[/tex]
We read from the normal distribution table to get;
P(X>115)=0.5675
By converting the IQ score of 115 into a Z score and finding the area to the right of this Z score in a standard normal distribution, we find that the probability of a randomly selected individual's IQ being over 115 is approximately 0.57 or 57%.
Explanation:To answer this question, we need to understand how a normal distribution works. A random variable X, such as an individual's IQ, that is normally distributed can be converted into a standard normal variable Z, using the formula Z = (X - mean) / standard deviation.
In our case, the mean IQ is 118 and the standard deviation is 18. Therefore, to find the probability that a randomly selected individual's IQ is over 115, we convert 115 into a Z score using the aforementioned formula: Z = (115 - 118) / 18 = -0.167. This is the Z score for an IQ of 115.
To find the probability that a randomly selected individual's IQ is more than 115, we find the area to the right of Z = -0.167. From standard normal tables, we know that the area to the left of Z = -0.167 is approximately 0.4332. Therefore, the area to the right (which is the probability we want) is 1 - 0.4332 = 0.5668.
So, the probability that a randomly selected individual's IQ is over 115 is approximately 0.57 (or 57% when expressed as a percentage).

with a head wind, it takes 7 hours to fly 2800 miles from miami to seattle. with a tailwind, and the same airspeed, it takes 5 hours to fly in the opposite direction, from seattle to miami. find the airspeed and the windspeed
Answer:
Plane speed: 480mph
Wind speed: 80mph
Step-by-step explanation:
Miami to Seattle: time = 7hrs
Speed (s) = 2800mph
D = speed/time = 2800/7
= 400mph
Seattle to Miami:
Same speed = 2800mp
Time = 5hrs
Distance (D) = speed/time
= 2800/5 = 560mph
Let p be speed of plane and w wind speed.
Therefore, P+w = 560. . .1
P-w = 400. . .2
2p = 960
P = 960/2 = 480
Therefore, P + w = 560
480 + w = 560
W = 80mph
While P = 480mph

What is the solution to the system
The solution to system is x = 0 and y = -1
Solution:
Given system of equations are:
-8x + 2y = -2 ----------- eqn 1
4x + 4y = -4 ---------- eqn 2
We have to solve the system of equations
We can solve the equations by elimination method
Multiply eqn 2 by 2
8x + 8y = -8 ------ eqn 3
Add eqn 1 and eqn 3
-8x + 2y = -2
8x + 8y = -8
( + ) ---------------
0x + 2y + 8y = -2 - 8
10y = -10
Divide both sides by 10
y = -1
Substitute y = -1 in eqn 1
-8x + 2(-1) = -2
-8x - 2 = -2
-8x = -2 + 2
x = 0
Thus the solution to system is x = 0 and y = -1
There are 19 animals , total of legs are 54 and the animals are pigs and ducks. How many pigs and ducks are there?
Final answer:
Using a system of equations, we established that there are 8 pigs and 11 ducks among the 19 animals with a total of 54 legs.
Explanation:
To solve the problem of determining how many pigs and ducks there are when there are 19 animals in total and 54 legs, we set up two equations. Let's assume the number of pigs is x and the number of ducks is y. Pigs have 4 legs, and ducks have 2 legs. We can summarize this information in the following system of equations:
Equation 1: x + y = 19 (because there are 19 animals total)
Equation 2: 4x + 2y = 54 (because the total number of legs is 54)
We can solve this system using the substitution or elimination method. Simplifying Equation 2 by dividing every term by 2 gives us 2x + y = 27, which we'll call Equation 3.
Equation 3: 2x + y = 27
We can now subtract Equation 1 from Equation 3 to find the value of x:
(2x + y) - (x + y) = 27 - 19
(2x - x) + (y - y) = 8
x = 8 (number of pigs)
Substitute x back into Equation 1:
x + y = 19
8 + y = 19
y = 19 - 8
y = 11 (number of ducks)
Therefore, there are 8 pigs and 11 ducks among the 19 animals.

A certain number was multiplied by 7.4 was then taken away from the product. Finally that difference was then divided by 9, resulting in 5. Find the initial number.
The initial number is 7.
Step-by-step explanation:
Let the initial number be 'x'.
The number was multiplied by 7 ⇒ 7x4 was then taken away from the product ⇒ 7x-4That difference was then divided by 9 resulting in 5 ⇒ (7x-4)/9 = 5⇒ 7x-4 = 45
⇒ 7x = 49
⇒ x = 7
The initial number is 300. Multiply by 7.4 to get 2220, subtract 2220, then divide by 9 to get 247. Confirming: 7.4(300) - 2220 = 247(9) = 5.
Let's denote the initial number as ( x ). According to the given information:
1. Multiply by 7.4: ( 7.4x )
2. Take away from the product: ( 7.4x - (7.4x) )
3. Finally, divide by 9:[tex]\( \frac{{7.4x - 7.4x}}{9} \)[/tex]
We know that this resulting expression equals 5:
[tex]\[ \frac{{7.4x - 7.4x}}{9} = 5 \][/tex]
Now, let's solve for ( x ):
[tex]\[ \frac{{0}}{9} = 5 \][/tex]
As ( 7.4x ) cancels out, we are left with ( 0 = 5 ), which is not a valid equation.
What is the nth term of the geometric sequence -2,10,-50
Answer:
[tex]T_n=-1(-5)^n^-^1[/tex]
Step-by-step explanation:
We are given;
A geometric sequence;
-2,10,-50
Required to determine the nth term
The nth term in a geometric sequence is given by the formula;
[tex]T_n=a_1r^n^-^1[/tex]
where [tex]a_1[/tex] is the first term and r is the common ratio;
In this case;
[tex]a_1=-2[/tex]
r = 10 ÷ -2
= -5
Therefore;
To get the nth term in the given geometric sequence we use;
[tex]T_n=-1(-5)^n^-^1[/tex]
Thus, the nth term is [tex]T_n=-1(-5)^n^-^1[/tex]

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.
To find the circumference of a circle, use the formula C = 2πr. To find the area, use the formula A = πr^2.
Explanation:The question asks to match each circular flower bed on the left to its circumference and its area on the right. In order to find the circumference of a circle, we use the formula C = 2πr, where r is the radius of the circle.
To find the area of a circle, we use the formula A = πr^2. We can use these formulas to calculate the circumference and area of each circular flower bed and match them to the options on the right.
For example, if a circular flower bed has a radius of 3 meters, we can find its circumference by plugging the radius into the formula: C = 2π(3) = 6π meters. Similarly, we can find its area by plugging the radius into the formula: A = π(3^2) = 9π square meters.
