Answer:

a. To write a linear function that relates the length of hair to the number of months, we need to find the slope and y-intercept of the line that passes through the given points. We can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

Using the given data, we can find the slope as:

m = (y2 - y1) / (x2 - x1) = (14.0 - 11.0) / (6 - 0) = 0.5

And we can find the y-intercept as:

b = y - mx = 11.0 - 0.5(0) = 11.0

So, the linear function that relates the length of hair to the number of months is:

y = 0.5x + 11.0

We can also graph this function as a straight line, passing through the given points (0, 11.0), (3, 12.5) and (6, 14.0), as shown below:

linear function graph

b. The slope of the function is 0.5, which means that the length of hair increases by 0.5 inches every month. In other words, the slope represents the rate of change of hair length with respect to time.

The y-intercept of the function is 11.0, which means that if the person doesn't cut their hair at all (i.e., x = 0), their hair length would still be 11.0 inches. In other words, the y-intercept represents the starting value of the hair length.

The listed price of the TV that Wayne bought was $947.37

Here we know that Wayne pays $660 for a TV whose price was marked down by (30 + 1/3)%

We can rewrite that discount as 0.30333... in a decimal form (get that just by dividing the percentage by 100%)

Then if the lited price of the TV is P, we can write the equation for the discount as follows:

660  = P*(1 - 0.3033...)

The number that we subtract is the percentage in decimal form.

Solving this for P gives:

P = 660/(1- 0.3033...) = 947.37

The listed price was 947.37 dollars.

According to the given information, the solution to H(x) = 3 is x = 2.

What is equation?

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of two parts: the left-hand side (LHS) and the right-hand side (RHS). The LHS and RHS are separated by an equals sign (=), indicating that they have the same value. The general form of an equation is: LHS = RHS

To solve for x when H(x) = 3, we substitute 3 for H(x) in the equation and solve for x:

H(x) = -x + 5

3 = -x + 5

Subtracting 5 from both sides, we get:

-2 = -x

Multiplying both sides by -1, we get:

2 = x

Therefore, the solution to H(x) = 3 is x = 2.

The area of the triangle, A(x), can be expressed as A(x) = (x * sqrt(3x^2/4))/2 and the height of the triangle, h, can be expressed as h = sqrt(3x^2/4) in terms of the base.

The landowner wishes to use 3 miles of fencing to enclose an isosceles triangular region of as large an area as possible. Let x be the length of the base of the triangle.The length of the base of the triangle is x miles, while the length of the other two equal-length sides are 2x miles each. Thus, the total length of the three sides of the triangle is 3x miles, which equals 3 miles of fencing as required.

To find the area of the triangle, we must first calculate the height of the triangle. Using the Pythagorean Theorem, we can calculate the height of the triangle in terms of the base. The formula is h^2 = (2x)^2 - (x/2)^2. Thus, the height of the triangle, h, can be expressed as h = sqrt(3x^2/4).The area of the triangle is equal to the base multiplied by the height and divided by two. Thus, the area of the triangle, A(x), can be expressed as A(x) = (x * sqrt(3x^2/4))/2.

The surface area of the rectangular prism is 170 square yards.

Surface area is the total area of a three-dimensional shape's surface. Add the areas of all six faces to find the surface area of a cuboid with six rectangular faces. Alternatively, label the cuboid's length (l), width (w), and height (h) and use the formula: surface area (SA)=2lw+2lh+2hw.

To calculate the surface area of the rectangular prism, add the areas of each of its faces.

The front and back faces are 5 yards by 6 yards in size, so each has an area of:

5 yards x 6 yards equals 30 square yards

The top and bottom faces are 5 yards by 5 yards, so each has an area of:

5 yards x 5 yards equals 25 square yards

The two side faces have dimensions of 6 yards by 5 yards, for a total area of:

30 square yards = 6 yards x 5 yards

As a result, the surface area of the rectangular prism is as follows:

Front face area plus back face area plus top face area plus bottom face area plus left side face area plus right side face area

= 30+30+25+25+30+30

= 170 square yards

As a result, the rectangular prism has a surface area of 170 square yards.

First, we should calculate the profit made by the shopkeeper. To calculate the profit, we will multiply the selling price of the table with 20%, which is 20% of 5400, or 1080.

Next, we should subtract the profit from the selling price to find the cost price of the table.

The cost price of the table = 5400 - 1080

The cost price of the table = 4320

Therefore, the cost price of the table is ₹ 4320.

The cost of each store in two months is: Store A is 4281, Store B is 5485, Store C is 3153, and Store D is 6413.

Step-by-step explanation:

If the cost price of 20 articles is the same as selling price of 16 articles, then the gain percentage is 25%

To find the gain percent, we first need to calculate the profit earned on the sale of the 16 articles.

Let the cost price of each article be "C" and the selling price of each article be "S".

Given that the cost price of 20 articles is the same as the selling price of 16 articles, we can write:

20C = 16S

We can simplify this equation to:

S = (20/16)C = (5/4)C

Now, let's calculate the profit earned on the sale of 16 articles:

Profit = Total Selling Price - Total Cost Price

Profit = 16S - 20C

Profit = 16(5/4)C - 20C

Profit = 5C/2

The profit earned is 5C/2. The profit percent can be calculated as:

Profit Percent = (Profit / Cost Price) x 100

Profit Percent = (5C/2) / (20C) x 100

Profit Percent = 25%

The speed of car is found as : 1 of 1140 miles per minutes.

The total number of miles the car will travel in 20 minutes is: 1 / 50 miles.

The same attribute is expressed using a unit conversion, but in a diverse unit of measurement.

For e.g., time can be highlighted in minutes rather than hours, and distance can be verbalized in kilometers, feet, or another comparable measurement unit instead of miles.

Speed of car =  3 of 57 miles per hour.

Speed of car =  3 mi / 57 hr

We know, 1 hour = 60 minutes;

So,

Speed of car =  3 mi / 57*60 min

Speed of car =  1 mi / 57*20 min

Speed of car =  1 mi / 1140 min

Thus, the speed of car is found as : 1 of 1140 miles per minutes.

In 20 minute:

Number of miles = 1 mi / 1140 min * 20 min

Number of miles = 20 / 1140 min

Number of miles = 1 / 50 miles

Thus, the total number of miles the car will travel in 20 minutes is: 1 / 50 miles.

The marketing campaign by Snyder's Moving company was profitable, generating an additional profit of $31,288 after subtracting the cost of the campaign. The total revenue generated after the campaign was $403,588.

To determine the profitability of the marketing campaign, we need to calculate the additional profit generated by the clients who were convinced to use Snyder's for residential moves.

Let's start by calculating the number of clients in each segment

Clients who fall into both categories, 0.1 x 2,200 = 220

Clients in each segment, (2,200 - 220) / 2 = 990

Now let's calculate the revenue generated by each segment

Revenue from clients in each segment: 990 clients x $260 profit per move = $257,400

Revenue from clients who fall into both categories: 220 clients x 2 moves x $260 profit per move = $114,400

Total revenue generated: $371,800

Now let's calculate the revenue generated after the marketing campaign

10% of 990 SB-only clients decided to use Snyder's for residential moves

0.1 x 990 = 99 clients

Additional revenue generated from these clients: 99 clients x $260 profit per move x 1.15 (15% higher price for SB moves) = $31,788

Total revenue generated after the marketing campaign, $403,588

Finally, let's subtract the cost of the marketing campaign

Profit generated after the marketing campaign: $403,588 - $500 = $403,088

Therefore, the marketing campaign was profitable, generating an additional profit of $31,288.
