Stage 1: Cartesian Plane INFORMATION: A Cartesian Plane is used for sketching Graphs as well as to perform transformations. 1.1 Describe the features of a Cartesian Plane in terms of its axes, the direction of the axes and its centre.
A cartesian plane is a plane with two axes namely x axis and y axis.
A Cartesian plane is a graph with one x-axis and one y-axis and thus is also sometimes known as a x y graph.
These two axes are perpendicular to each other that is they form an angle of 90° with each other.
The origin (O) is in the exact center of the graph and is the point where the two axes intersect.
Numbers to the right of the zero on the x-axis are positive and the numbers to the left of zero are negative. ( as the case in number line as well)
Similarly, the number on the top of the center on y axis are positive and the numbers below are negative.
It can be used to represent any 2 D figure.
Therefore, a cartesian plane is a plane with two axes namely x axis and y axis.

A fair spinner is used with four equal sections numbered 1,2,3,4. Assume that the pointer cannot land on a line. But the spinner is spun only once. Determine the probability. P(2 or even)
Probability of getting a 2 or even(4) is expected outcomes divided by total outcomes(4). The answer is P(2 or even)= 2/4 = 1/2.
A fair spinner is used with four equal sections numbered 1,2,3,4.
Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. Probability of an Event. Assume an event E can occur in r ways out of a sum of n probable or possible equally likely ways. Then the probability of happening of the event or its success is expressed as; P(E) = r/n. The probability that the event will not occur or known as its failure is expressed as: P(E’) = (n-r)/n = 1-(r/n).
P(2) = expected outcomes/total number of outcomes
=> 1/4
P( even:4) = 1/4
So; P(2 or even)= 1/4 + 1/4 = 2/4 or 1/2

Answer:
Expected results are divided by total outcomes to determine the probability of getting a 2 or even (4). (4). P(2 or even) = 2/4 = 1/2 is the response.
Step-by-step explanation:
There are four equal portions on a fair spinner, designated 1, 2, 3, and 4.
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution. the likelihood of an event. Assume that there are n probable or plausible equally likely ways for an event E to occur. Then, P(E) = r/n is used to represent the likelihood that the event will occur or that it will be successful. P(E') = (n-r)/n = 1-(r/n) denotes the chance that the event will not occur, also known as its failure.
P(2) = expected outcomes/total number of outcomes
=> 1/4
P( even:4) = 1/4
So; P(2 or even)= 1/4 + 1/4 = 2/4 or 1/2

What is the minimum score you need on the fourth test to get an B for the course?To get a B, you need to get an average of 80% in all four scores.
The first 3 tests have a total of 100 points, and you got:
79, 77, and 91
So the percentage that you got in these 3 tests is:
79%, 77%, 91%
Now, let's say that X is the percentage you get in the last test, we must have that the average is 80%, then:
(79% + 77% + 91% + X)/4 = 80%
Solving that for x, we will get:
X = 4*80% - $79 - 77% - 91% = 73%
So you need to get at least a 73% of the last test, and that test has 200 points, so you need to get:

One could calculate an affordable monthly rate for rent and expenses by dividing annual income by 12 and calculating 30% of that figure
write this as an equation
One popular rule of thumb is the 30% rule,
which says to spend around 30% of your gross income on rent.
So if you earn $2,800 per month before taxes,
you should spend about $840 per month on rent.
To calculate,
simply divide your annual gross income by 40 - if you make $120,000 a year, you can spend $3,000 on rent.
An equivalent is the 30% rule, meaning that you can put 30% of your annual gross income in rent.
If you make $90,000 a year, you can spend $27,000 on rent, and so your monthly rent will be $2,250.
Typically, the rents that landlords charge fall between 0.8% and 1.1% of the home's value.For example, for a home valued at $250,000, a landlord could charge between $2,000 and $2,750 each month.
If your home is worth $100,000 or less, it's best to charge rent that's close to 1% of its value.
To determine daily rent, the total number of days are divided by the monthly rent.
The daily rent is then multiplied by the number of days the tenant occupies the property.To get an appropriate calculation for how much each roommate should pay depending on the size of their room, take the square footage of each room and divide by the total square footage of the apartment. This will give you a percentage for the size and value of each room, which you can apply to the total cost of rent.

We can solve using cross products
x * x = 6(x+5)
x^2 = 6x+30
Subtract 6x from each side
x^2 -6x= 6x+30-6x
x^2 -6x= 30
Subtract 30 from each side

x^2 -6x -30 =0
Using the quadratic formula
x = -b ± √(b^2 -4ac)

Given the following functions, find the indicated values.
Answer:
(a) f(-3) = 27
(b) f(0) = 6
(c) f(4) = -22
Step-by-step explanation:
To solve, we will input x as -3 into the function.
f(x) = 6 - 7x
f(-3) = 6 - 7(-3)
f(-3) = 27
We will do this for the other values as well.
f(x) = 6 - 7x
f(0) = 6 - 7(0)
f(0) = 6
-
f(x) = 6 - 7x
f(4) = 6 - 7(4)
f(0) = -22
The supply and demand for a product are given by
2p − q = 60 and pq = 100 + 25q,
respectively. Find the market equilibrium point
The market equilibrium point will be at a price of 70 and the quantity of 80.
How to calculate the equilibrium?From the information, the supply and demand for a product are given by 2p − q = 60 and pq = 100 + 25q.
From 2p − q = 60
q = 2p - 60
Substituting this in pq = 100 + 25q.
p(2p - 60) = 100 + 25(2p - 60)
2p² - 70p = 100 + 50p - 1500
2p² - 70p - 50p - 100 + 1500 = 0
2p² - 120p + 1400 = 0
Divide through by 2
p² - 60p + 700 = 0
p² - 70p + 10p - 700 = 0
p(p - 70) + 10(p - 70) = 0
p - 70 = 0
p = 0 + 70 = 70
Since 2p − q = 60
2(70) - q = 60
140 - q = 60
q= 140 - 60 = 80
Therefore, the market equilibrium point will be at a price of 70 and the quantity of 80.

A basket of fruits, which is on a top of a 1.5m high table has a GPE of 44.12. What is the mass of the basket of fruits?
Answer:
3.00 kg (2 d.p.)
Step-by-step explanation:
Gravitational Potential Energy (GPE): Energy stored in a mass due to its position. The amount of GPE an object has depends on its mass and its height above the ground.
[tex]\large\boxed{\textsf{GPE}=mgh}[/tex]
where:
GPE = gravitational potential energy in joules (J).m = mass in kilograms (kg).g = gravitational field strength in newtons per kilogram (N/kg).h = change in height in meters (m).Given:
GPE = 44.12 Jg = 9.8 N/kgh = 1.5 mSubstitute the given values into the formula and solve for m:
[tex]\implies 44.12=m \times 9.8 \times 1.5[/tex]
[tex]\implies 44.12=14.7m[/tex]
[tex]\implies m=\dfrac{44.12}{14.7}[/tex]
[tex]\implies m=3.001360544...[/tex]
[tex]\implies m=3.00\:\:\sf kg\:(2\:d.p.)[/tex]

Select Choice
kilometers per hour faster.
Using the relation between velocity, distance and time, it is found that the penny has a faster unit rate per hour. It travels about 56.4 kilometers per hour faster.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
The rocket traveled 208 kilometers in 50 minutes = 5/6 of an hour, hence it's velocity, which is the unit rate, is given by:
v = 208/(5/6) = 208 x 6/5 = 249.6 km/hour.
The penny travels 153 kilometers in a half an hour, hence it's velocity is given by:
v = 153/0.5 = 306.
306 > 249.6, 306 - 249.6 = 56.4, hence:
The penny has a faster unit rate per hour. It travels about 56.4 kilometers per hour faster.
