How do you find the number of functions from class 11 to B?
Number of functions. It is an important topic in sets and relation. A relation in which each input has a specific output is called a function. If f is a function from set A to set B, then each element of A will be plot with only one element in B.
1. Number of possible functions: If a set A has j elements and set B has k elements, then the number of functions possible from A to B is j ^k.
2. Number of Injective Functions (One to One): If set A has j elements and set B has k elements, j ≥k, then the number of injective functions or one to one function is given by j! / (j-k)!
3. Number of Bijective functions: If there is bijection between two sets A and B, then both sets will have the same number of elements. If n(A) = n(B) = m, then number of bijective functions = m!

graph 2y – 4x < 8 thanksss
The solution is the set of all points (x,y) that satisfy the inequality y < 2x + 4.
What is the graph of a function?
The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
To solve the inequality 2y – 4x < 8, we can start by isolating y by adding 4x to both sides:
2y < 4x + 8
then divide both sides by 2:
y < 2x + 4
This is the solution in slope-intercept form (y = mx + b), where the slope is m = 2 and the y-intercept is b = 4.
To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.
You can use x = -2, x = -1, x = 0, x = 1, x = 2, for example and find the y-values for each x, y < 2* -2 + 4 = 0, y < 2* -1 + 4 = 2, y < 20 + 4 = 4, y < 21 + 4 = 6 and y < 2*2 + 4 = 8.
Then plot those points on a coordinate plane and draw the line that goes through them, and shade the half-plane that is below the line
Hence, the solution is the set of all points (x,y) that satisfy the inequality y < 2x + 4.

Luca decided to walk to a new park in town and estimated how long it would take. When he arrived, it had taken him 20 minutes to walk to the park. His estimate was 25% more than that. How long did Luca estimate it would take him to walk to the park
Answer: If it took Luca 20 minutes to walk to the park and his estimate was 25% more than that, we know that the estimate was 20 * 1.25 = 20 + (20 * 0.25) = 20 + 5 = 25 minutes.
So Luca estimated that it would take him 25 minutes to walk to the park.

The easiest points to take on the line are those where x =0, y = 35 (0,35) and x = 7, y =0 (7,0)
Question 2.
We can see that between these two points, the y value decreases linearly from 35 to 0. So the rise between (0, 35) and (7,0) = [tex]0 -35 = -35[/tex]

When asked to rewrite $364 + 728 as a product of the GCF and the sum of two numbers a student wrote 364 (1 + 2) is the student correct why or why not?
Answer: The student got the wrong answer. ✅
Step-by-step explanation: When you add 364 and 728 together, you get 1092. To make it easier to understand, it is like having 3 piles of 100, 6 piles of 10, and 4 ones on one side, and 7 piles of 100, 2 piles of 10, and 8 ones on the other side, when you put them together you get 10 piles of 100, 8 piles of 10 and 12 ones.
To find the biggest number they have in common, you can divide both numbers by 2 and you get 182 and 364.

slope=7;(4,-30)
what is the y-intercept
and what is the equation
Answer:
The y-intercept is -58
The equation is y=7x-58
Step-by-step explanation:
We'll look for an equation of the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
We are given the slope and one point on a line. The slope, m, of 7 leads us to:
y=7x+b
We need a value for b that will force the line to go through point (4,-30). Enter that point in the above equation and solve for b:
y = 7x+b
-30 = 7(4)+b for point (4,-30)
-30 = 28 + b
b = -58 [b is the y-intercept]
The equation is y = 7x-58

The graph shows the distance y (in miles) that a bus travels in x hours. Find and interpret the slope of the line.
A line graph titled "Bus Trip"
The x-axis is labeled time, in hours. The y-axis is labeled distance, in miles. A line begins at ordered pair (0, 0 )and goes through ordered pair (1, 60) and ordered pair (2, 120).
The slope of the line is __ The bus is traveling at a speed of __ miles per hour.
The slope of the line is 60 The bus is traveling at a speed of 60 miles per hour.
What is the slope?A line's steepness is determined by its slope. Slope can be computed mathematically as "rise over run" (change in y divided by change in x). In the slope-intercept form, the equation for the line is expressed as follows: y = mx + b, where m denotes the slope and b the y-intercept. When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilized (0, b). Its y value of the y intercept point is represented by b in the equation.
Given that,
A line begins at ordered pair (0, 0) and goes through ordered pair (1, 60) and ordered pair (2, 120).
Slope of the line (m) = (y₂ - y₁) / (x₂ - x₁)
m = 120 - 60 / 2 - 1
m = 60
thus, slope of the line = 60

Margaret is incorrect because the given information does not include enough details to determine if the quadrilateral WXYZ is a parallelogram.
To prove that a quadrilateral is a parallelogram, the four sides must be equal in length and the opposite angles must be congruent. The given information does not include any measurements or angles, so it is not possible to determine if the quadrilateral is a parallelogram.
No, 144 inches of tape is not enough to finish the job. The hazard sign has two identical parallelogram-shaped stripes, and each stripe will require more than 144 inches of tape to outline. The area of a parallelogram can be calculated using the formula A = bh, where b is the base and h is the height. In order to determine how much tape is needed to outline the stripes, the base and height of the parallelograms must be known.
There is not enough information to prove that a quadrilateral is a parallelogram, as all four sides must be equal in length and the opposite angles must be congruent.

How many combinations of 8 are there?
There are one combination of choosing all 8 from 8 items when the order does not matter.
Therefore the answer is 1.
The number of combinations of 8 items is given by the formula:
C(n, k) = n! / (k!(n-k)!)
where n is the total number of items and k is the number of items in each combination.
In this case, we want to find the number of combinations of 8 items, so n = 8 and k = 8.
Plugging these values into the formula, we get:
C(8, 8) = 8! / (8!(8-8)!) = 8! / (8!(0!))
= 8! / 8! = 1.
So, there is only 1 combination of 8 items when k = 8.
It's important to note that a combination is a set of items in which the order doesn't matter, so the order of the items in the set doesn't affect the number of combinations. If you want to find the number of permutations, in which order matters, it would be 8! (8 factorial) = 8x7x6x5x4x3x2x1 = 40320.
