How do you know if a function is continuous or discontinuous?
A function is continuous if its graph is a single, unbroken line without any gaps. A function is discontinuous if its graph has breaks in it, or if it is undefined at certain points.
A function is continuous if its graph is a single, unbroken line without any gaps. This means that the function must have a defined value for every value of the independent variable. If the graph of the function is smooth, without any abrupt changes or jumps, then it is continuous. A function is discontinuous if its graph has breaks in it, or if it is undefined at certain points. This means that the function is not defined at certain values of the independent variable and hence, the graph is not a single, unbroken line. Discontinuities can arise from various sources, such as a function having an infinite value, a function having a zero value or a function having an undefined value. The graph of a discontinuous function typically has gaps or jumps, and it is not a single, unbroken line.

What is arithmetic sequence?
The difference between each consecutive term in an arithmetic sequence is constant.
An explicit formula for an arithmetic sequence is a = d(n - 1) + c, where d is the common difference between consecutive terms.
According to the given question:
The first term in an arithmetic sequence is 5 that is a = 5
Now, the third term in the sequences is -1
a₃ = a + 2d
By substituting the value of a and a₃ we can find d for the arithmetic sequence.
-1 = 5 + 2d
2d = -6
d = -3
So, the explicit form that would be used to find the nth term in the sequence is

What is the slope of the line y =- 3x 1 3?
The slope of the line y =3x(1 ,3) is 3.
Describe slope.The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same). In math, we frequently want to quantify the steepness. Slopes B and C are clearly higher than slope A. While slope A is just four units high, they are both seven units high. Therefore, it would seem that height and steepness are related.

What is Circumcentre and Orthocentre?
Step-by-step explanation:
circumcentre:
In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polygon has a circumscribed circle.
othocentre:
The orthocenter is the intersection point of three altitudes drawn from the vertices of a triangle to the opposite sides. A centroid is the intersection point of the lines drawn from the midpoints of each side of the triangle to the opposite vertex.
we define a bow-tie quadrilateral as a quadrilateral where two sides cross each other. an example of a bow-tie quadrilateral is shown below. seven distinct points are chosen on a circle. we draw all chords that connect two of these points. four of these chords are selected at random. what is the probability that these four chosen chords form a bow-tie quadrilateral?
The probability of forming a bow-tie quadrilateral from four randomly chosen chords is approximately 6.25%.
This is because there are exactly 28 possible quadrilaterals that can be formed from the seven given points, and only one of those 28 quadrilaterals is a bow-tie quadrilateral. This means that the probability of forming a bow-tie quadrilateral is 1/28, which is equal to 0.0357, or 3.57%.
To explain further, when we draw all of the chords from the seven given points, we have 21 distinct chords. Out of these, 10 chords form triangles, leaving us with 11 chords that form quadrilaterals.
Since four of these chords are randomly chosen, the number of possible combinations of quadrilaterals that can be formed is equal to 11C4, or 495. Out of these 495 combinations, only one is a bow-tie quadrilateral. This means that the probability of forming a bow-tie quadrilateral is 1/495, or 0.002041, or 0.2041%.
Since 0.2041% is too small to be expressed as a whole number, it is rounded up to 6.25.

that outputs the total points the Dragons scored (p) based on
the number of 2-point baskets made (b).
Slope:
Y-Intercept:
Equation (in slope-intercept form):
Answer:
Slope: 2
Y-Intercept: 47
Equation (in slope-intercept form): p = 2b + 47.
Step-by-step explanation:
To determine the equation, slope, and y-intercept for a function that outputs the total points the Dragons scored based on the number of 2-point baskets made, you will need to use the information given about the number of 3-pointers, foul shots, and 2-point baskets made.
First, let's define p as the total number of points the Dragons scored and b as the number of 2-point baskets made.
We know that the Dragons scored a total of 12 three-pointers * 3 points per 3-pointer + 11 foul shots * 1 point per foul shot = 47 points from 3-pointers and foul shots.
Therefore, the total number of points the Dragons scored can be expressed as:
p = 47 points + 2 points per 2-point basket * b 2-point baskets
This equation is in slope-intercept form, with the slope being 2 points per 2-point basket and the y-intercept being 39 points.
The equation in slope-intercept form is:
p = 2b + 47
Therefore, the slope of the function is 2, the y-intercept is 39, and the equation is p = 2b + 47.

Rohit earns rupees 1500 and spends rupees 1250 per month. Find the ratio between his:
a) savings and expenditure b) expenditure and income c) income and savings
Step-by-step explanation:
To find the ratio between Rohit's savings and expenditure, we need to divide his savings by his expenditure:
Savings / Expenditure = (1500 - 1250) / 1250 = 250 / 1250 = 1/5
The ratio between Rohit's savings and expenditure is 1/5.
To find the ratio between Rohit's expenditure and income, we need to divide his expenditure by his income:
Expenditure / Income = 1250 / 1500 = 5/6
The ratio between Rohit's expenditure and income is 5/6.
To find the ratio between Rohit's income and savings, we need to divide his income by his savings:
Income / Savings = 1500 / (1500 - 1250) = 1500 / 250 = 6/1
The ratio between Rohit's income and savings is 6/1.

Answer:
a) 47
b) 61
Step-by-step explanation: We can setup two equations from the information given above:
2c + 4b = 14 where c is the cost if one carousel ticket and b is the cost of four bumper car tickets.
6c + 9b = 33 where where c is the cost if one carousel ticket and b is the cost of four bumper car tickets like in the 1st equation.
If you divide the second equation by 3, you get 2c + 3b = 11, leaving 2c in both equations.
If you subtract both equations by the elimination method:
2c + 4b = 14
-
2c + 3b = 11
---------------------------
b = 3, which solves for the cost of one bumper car ticket
If you plug this value back into the first (or second) equation,
ex. 2c + 4(3) = 14 -> 2c = 2 -> c=1
You get c = 1, which solves for the cost of one carousel ticket.
Then you plug these values (c=1 and b=3) in a) and b):
a) 8*1 + 13*3 = 47
b) 10*1 + 17*3 = 61

What is the formula for finding the altitude?
The formula for finding the altitude of an equilateral triangle is ((sqrt (3))/2)a.
As we know, the sides of an equilateral triangle are equal. Let the side of the triangle be 'a'.
Dropping a perpendicular from the vertex of the triangle, the triangle gets divided into two right triangle where the base of the triangle is divided into two as well.
Therefore, by using the Pythagoras' theorem,
we can get the altitude (say 'h') of the triangle by:
h^2 = a ^ 2 - (a/2) ^ 2 = 3a ^ 2/4
h = sqrt (3a^2/4) = ((sqrt (3))/2)a.

What are the 2 types of functions give examples?
The two types of functions are linear and non linear functions.
A linear function is a function that can be written in the form f(x) = mx + b, where m and b are constants. This type of function has a constant rate of change, meaning the output will always increase or decrease the same amount for a given change in the input. For example, if the input increases by 3, the output will increase by 6. An example of a linear function is f(x) = 3x + 5. This function will always increase by 3 for each increase in the input, and will always have a y-intercept of 5.
A non-linear function is a function that cannot be written in the form f(x) = mx + b. This type of function has a variable rate of change, meaning the output will increase and decrease at different rates for different changes in the input. An example of a non-linear function is f(x) = x2 - 4x + 5. This function will increase and decrease at different rates for different changes in the input, and will always have a y-intercept of 5.

What is the relationship between the base and height when you are finding the area of a triangle?
The base in term of the height of the triangle is written as ;b = 2A/h.
Define the term area of a triangle?A closed triangle has three sides. It is among the fundamental geometric shapes because it has three vertices and three sides.
Based on the length of its sides, a triangle can be labeled as equilateral, isoscles, or scalene.A two-dimensional shape's area is the space the shape takes up. By dividing the shape equal unit squares and counting them, since each unit square takes up one square unit space, the area may be obtained.Think about the ABC scalene triangle. Keep in mind that the height of a triangle must be perpendicular towards the base in order for its area to be expressed as being half that of a rectangle. Create a perpendicular hence from a vertex to the opposite side.Thus, the formula for the are area of the triangle is -
A = 1/2 bh
In which,
b = base of the triangle.

find the area of the largest rectangle that can be inscribed in the ellipse x2 a2 + y2 b2 = 1
The area of the largest rectangle that can be inscribed in the ellipse is 2ab
The term ellipse in math is a circle that has been stretched in one direction to give it an oval shape
Here we have given the following equation x²/a² + y²/b² = 1
Now, we have to find the area of the largest rectangle that can be inscribed in the ellipse
Here we all know that the Area of rectangle = 4xy
That can be written as A = 4xy
Now, we have to differentiate the given expression then we get,
=> dA/dx = 4xdy/dx + 4y ----------------------(1)
Here we have given an equation x²/a² + y²/b² = 1
Now, we have to differentiate this one also, then we get,
=> 2x/a² + 2y(dy/dx)/b² = 0
If we equate both of the equation then we get the value as.
=> dy/dx = - xb²/a²y
Now, substitute the values on equation (1), then we get,
=> dA/dx = 4x( - xb²/a²y) + 4y
Equate the expression with 0, then we get the value of
=> a²y² = b²x²
=> x²/a² = y²/b²
When we simplify this one then we get the value of x as (a/√2) and y as b/√2
Therefore, the Area is calculated as,
=> 4xy = 4(a/√2)(b/√2) = 2ab
So, the value 2ab is the area of the greatest rectangle that can be inscribed in an ellipse x²/a² + y²/b² = 1
