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)

By using the linear equation y=3x we draw the graph for proportional relationship.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A proportional relationship graph between two variables is a relationship where the ratio between the two variables is always the same

the graph of any proportional relationship is characterized by a straight line with data points passing through the origin (0, 0).

By the definition of proportional relationship of graph, we can reduce relationship between the values on the x-coordinate and y-coordinate of the given graph

As they are proportional and represented by euation

y = 3x

Where, x represent the time and y represent the number of sit-ups.

Hence by using the linear equation y=3x we draw the graph for proportional relationship.

What is the value of p will the function be continuous?

Answers

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.

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.

a² + b² = c²

a = b

So,

2a² = c²

a² = 100/2

Find the vertex of the function given below.
y = 2x² + 4x+1
A. (3,-4)
B. (-1,-1)
C. (1,7)
D. (-4,9)

Answers

The function has the vertex value of (-1, -1)

How to calculate the vertex of the function?

From the question, the definition of the functuion is given as

y = 2x² + 4x + 1

Start by differentiating the function

This is done as follows

y' = 4x + 4

Next, we set the differentiated equation to 0

So, we have the following equation

4x + 4 = 0

This gives

4x = -4

Divide by 4

x = -1

Next, we substitute x = -1 in the given equation y = 2x² + 4x + 1

So, we have the following equation

y = 2(-1)² + 4(-1) + 1

Evaluate

y = -1

Recall that

x = -1 and y = -1

So, we have

(-1, -1)

Hence, the vertex of the function is (-1, -1)

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?

Answers

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.

A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals. The numerator and denominator of positive common fractions are natural numbers.

The given expression is , 3/8d+3/4

From this, we have to eliminate the fraction for that we have to make common denominators like that,3/8 d + (3 * 2) / (4 * 2)=> 3/8 d + 6/8
