In this problem, we are dealing with equations where equations are mathematical statements containing two arithmetical expressions on both sides of the sign of 'equal to (=)'. It appears the relationship of equality between the expression composed on the left side with the expression composed on the proper side. In each condition we have, (L.H.S = R.H.S), left hand side = right-hand side. Conditions can be fathomed to discover the value of an unknown variable representing an unknown amount. If there's no 'equal to' symbol within the statement, it implies it isn't a condition. It'll be considered as an expression. Equations with 1 as the degree are considered linear equations. Equations with degree 2 are quadratic equations and the last Equations with degree 3 are known as cubic equations.
So , for 0n = 6 , it undefined as the L.H.S becomes zero
for 2n=6 => n=6/2=3

What is function and graph of a function?
A function from A to B is a rule that maps to each elements of A, a unique element of B.
A is the domain of the function and B is the co-domain of the function.
A collection of all points of the form [tex](x, f(x))[/tex] is called graph of the function.
Here,

What is the Pythagoras theorem?The right-angled triangle's relationship between its three sides is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The square of a triangle's hypotenuse is equal to the sum of its other two sides' squares, according to the Pythagoras theorem. The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC² = AB² + AC² in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

the graphs are attached herewith , where the label of the graph are :
along X-axis: 1 square division = 10 units
along y-axis: 1 square division: 10 units
The problem we dealing with is related to manipulating graphs.For the question 7 to 10, the commonly given function is f(x)= √x, if the g(x) is nothing but the f(x-c) or f(x+c), so for the g(X) to be f(x-c), then a graph of that particular function turns to stretch downward whereas, for the f(x+c), it stretches upward.
So, for 7 g(x)=√x- 4 where -4 is c so the g(x) = f(x-c) so the point for the graphs will stretch downward compare to the pint of the functions f(x)= √x.
8. g(x)=√x +3
here g(x)= f(x+3), so the pints stretched upward
9. g(x)=√x + 6 − 4=√x + 2
here additional number for the points ar 2, as it positive one, so the point of the function g(x), stretches upward
10. g(x)=√x - 7+3=√x -4
here the c is -4, so the point of the g(x), stretches downward.
Same for the questions 11 to 14, the common function is f(x) = 1/x ,for which which g(x) = f(x-c) or f(x+c), for positive c , the graph stretches upward otherwise it moves downward
11. g(x) = 1/x +4
here the c is positive, the graph stretches upward for the g(x)
12. g(x) = 1/x - 6
here the c is negative, the graph stretches downward for the g(x)
13. g(x) = 1/x-6 + 8= 1/x+2
here the c is positive, the graph stretches upward for the g(x)
14. g(x) = 1/x+7 -4= 1/x+3
here the c is positive, the graph stretches upward for the g(x)

What is the value of p will the function be continuous?
The value of p that will guarantee the continuity of the function is given as follows:
p = 6.5.
What is the continuity concept?A function defined by f(x) is continuous at a point x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
In the context of this problem, the continuity of the function will be guaranteed if the lateral limits at x = -1 are equal.
To the left of x = -1, the function is less than -1, hence the lateral limit is:
lim x -> -1^- f(x) = lim x -> -1 (-2x² - 8x + 3) = -2(-1)² - 8(-1) + 3 = 9.
To the right of -1, the function is greater than -1, hence the lateram limit is:
lim x -> -1^+ f(x) = lim x -> -1 (4x + 2p) = 4(-1) + 2p = -4 + 2p.
The lateral limits have to be equal for the function to be continuous, hence:
-4 + 2p = 9
2p = 13
p = 13/2
p = 6.5.

At the given speed it will take Fred 1.7 hours to run 8.5 miles.
An object's direction and rate of further travel are both regarded as parts of its velocity. By observing how fast and in which direction an object is moving, you may estimate its velocity.
Similar to speed, but also taking direction into account .Speed is hence directionless, but velocity denotes direction. Speed only offers a numerical representation of your speed.
Time taken by Fred to cover 6.25 miles = 1 1/4 = 1.25 hours
Speed of Fred = 6.25/1.25 = 5 miles per hour.
Distance to cover =8.25 miles
Time taken =8.25/5 = 1.7 hours.
Due to the addition of direction, velocity shows how quickly you are shifting your location. Because of this mismatch, if you travel very swiftly while your location stays the same, your velocity will only be 0.
Hence the time taken will be 1.7 hours.

your company wants to purchase swag gear for employees. they bought 5 sample merchandise at $ 450 each, 4 sample signs at $ 750 each, and 12 chromebooks with logo at $ 750 each. what is the average spent per article?
The company spent average amount $678.57 per article.
Average spent per article is calculated using the formula -
Average = sum of all observations ÷ total number of observations
In the question, observations are the different items bought by the company.
Amount spent on sample merchandise = 5 × 450
Amount spent on sample merchandise = $2250
Amount spent on sample signs = 4 × 750
Amount spent on sample signs = $3000
Amount spent on chromebooks = 12 × 750
Amount spent on chromebooks = $9000
Total amount spent = 2250 + 3000 + 9000
Total amount spent = $14,250
Number of articles = 5 + 4 + 12
Number of articles = 21
Average = 14,250 ÷ 21
Average = $678.57
Thus, the average spent per article is $678.57.

What is coordinate geometry?
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that M is the midpoint of CF for the points c(4,10) and f(10,10). To calculate the segment MF first let us calculate the midpoint M.
M = [ ( x₁ + x₂ ) / 2, ( y₁ + y₂ ) / 2 ]
M = [( 4 + 10 ) /2 , ( 10+10 ) / 2]
M = ( 7, 10)
The length of the segment MF will be:-
D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]
D = √ [ ( 10-10 )² + ( 10 - 4 )² ]
D = √36
