The quadratic function represented by the table is f(x) = -x² + 4x -1.

A polynomial of degree two in one or more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function.

Here, we have

Given: we have three variables a, b, and c, we can solve this problem by taking three points, say:

(0,-1), (2,3), and (4,-1)

Since we know that the function of the table is a quadratic function, we can start writing this function as follows:

f(x) = ax² + bx + c

So these points must satisfy the equation of the function.

For, (0,-1)

-1 = a(0)² + b(0) + c

c = -1

For, (2,3)

3 = a(2)² + b(2) + c

3 = 4a + 2b -1

4 = 4a + 2b

2 = 2a + b....(1)

For,  (4,-1)

-1 = a(4)² + b(4) + c

-1 = 16a + 4b - 1

4a + b = 0...(2)

Now, we have two equations to solve for a and b:

a = -1

b = 4

Now we put the value of a, b, and c in the given equation and we get

f(x) =  (-1)x² + 4x + (-1)

f(x) = -x² + 4x -1

Hence, the quadratic function represented by the table is f(x) = -x² + 4x -1.

Step-by-step explanation:

1 blue square on drawing is length 1/4 in but that means 4ft in reality.

so one blue square area correspongs to 4x4 = 16 square feet.

(a) there 6 tiles for the batrhroom = 6x16 sq.ft = 96 sq.ft and the cost will be $480

(b) bedroom + living area = 7x8-8 tiles = 48 tiles = 48 x 16 sq.ft. = 768 sq.ft = 85.33 sq. yards. So the cost will be 85.33*18=$1535.94

(c) unit cost for tile: $5/sq.ft

unit cost for carpet: $1535.94/768sq.ft = $2/sq.ft

The tile has a greater unit cost ($5 per sq.ft) than carpet ($2 per sq.ft)

Tiling the bathroom would cost $25. The price of five squares of tile, or the cost of tiling the bathroom, is: $5 x 5 squares is $25.

a. To calculate the cost of tiling the bathroom, we must first calculate its square footage. Assume the restroom measures 8 feet by 10 feet. We now have the area of:

960 square inches are equal to 8 feet by 12 inches per foot and 10 feet by 12 inches per foot.

The area of the bathroom can be divided by the area of each square, which is 14 inches on the blueprint, to determine the number of squares required:

14 inches by 14 inches divided by 960 square inches equals 4.96 squares.

As we are unable to purchase a fractional quantity of tile, we will round up to 5 squares.

The price of five squares of tile, or the cost of tiling the bathroom, is:

$5 x 5 squares is $25.

Consequently, tiling the bathroom would cost $25.

b. To calculate the cost of carpeting the bedroom and living room, we must first calculate the square footage of each space. Assume that the living room is 18 feet by 20 feet and the bedroom is 12 feet by 14 feet in size. These areas include:

Bedroom: 168 square feet (12 feet by 14 feet).

The living room is 360 square feet (18 feet by 20 feet).

Divide by 9 to convert square feet to square yards:

Bedroom 168 sq ft / 9 sq ft = 18.67 sq ft

The total cost for the customer for the entire year is  $48,600.

The customer wants to purchase 20 subscriptions for each of their 20 employees, so they need a total of 20 x 20 = 400 subscriptions.

Each subscription costs $10 per month for a yearly commitment,

so the cost for one subscription for a year would be $10 x 12 = $120.

Therefore, the total cost for 400 subscriptions for a year would be $120 x 400 = $48,000.

In addition, they need 1 extra subscription for a different service for every two employees, so they need 20 / 2 = 10 extra subscriptions.

Each extra subscription costs $5 per month for a yearly commitment, so the cost for one extra subscription for a year would be $5 x 12 = $60.

Therefore, the total cost for 10 extra subscriptions for a year would be $60 x 10 = $600.

Adding the cost of the extra subscriptions to the cost of the regular subscriptions, the total cost for the customer for the entire year would be $48,000 + $600 = $48,600.

Answer:

x = 13

Step-by-step explanation:

We know that 5x, x+12, and 90 makes a straight line, which is 180 degrees

5x + x+12 + 90 = 180

Combine like terms.

6x+102=180

Subtract 102 from each side.

6x+102-102=180-102

6x = 78

Divide each side by 6

6x/6 = 78/6

x = 13

Answer:

x = 13

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

We know that,

→ The angle of right angle is 90°.

Forming the equation,

→ (x + 12)° + (5x)° = 90°

Then the value of x will be,

→ (x + 12)° + (5x)° = 90°

→ x + 12 + 5x = 90

→ (x + 5x) + 12 = 90

→ 6x + 12 = 90

→ 6x = 90 - 12

→ 6x = 78

→ x = 78 ÷ 6

→ [ x = 13 ]

Hence, the value of x is 13.

For the equation 7/8 - 6/11, the best estimation is obtained as (1) - (1/2) = 1/2

To estimate 7/8 - 6/11, we need to find a common denominator for the two fractions.

One way to do this is to multiply the numerator and denominator of each fraction by the denominator of the other fraction.

So, we have -

(7/8) x (11/11) - (6/11) x (8/8)

= 77/88 - 48/88

= (77 - 48)/88

= 29/88

To simplify this fraction, we can look for common factors in the numerator and denominator.

The fraction 7/8 is almost 1 and the fraction 6/11 is almost 1/2.

Therefore, the best estimation of the equation 7/8 − 6/11 is -

(1) - (1/2) = 1/2

Therefore, the equation is obtained as (1) - (1/2) = 1/2.

The single equivalent discount rate for Company A is 19.28%, and for Company B is 23.18%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We are given;

The measures of company A and B= 8/10/14/4 10/6/16/3

Now,

To calculate the single equivalent discount rate for each company, we can use the following formula:

Single equivalent discount rate = [(1 - (Discount % / 100)) ^ (365 / Average payment period) - 1] x 100

For Company A, the average payment period is:

(8 + 10 + 14 + 4) / 4 = 9

Using the formula, we can calculate the single equivalent discount rate for Company A:

Single equivalent discount rate = [(1 - (8/100)) ^ (365 / 9) - 1] x 100 = 19.28%

For Company B, the average payment period is:

(10 + 6 + 16 + 3) / 4 = 8.75

Using the formula, we can calculate the single equivalent discount rate for Company B:

Single equivalent discount rate = [(1 - (10/100)) ^ (365 / 8.75) - 1] x 100 = 23.18%

Therefore, by percentage the answer will be 19.28% and 23.18%.

From the question, we are to determine whether the pair of lines are parallel, perpendicular or neither

To determine whether the pair of lines are parallel, perpendicular, or neither, we need to compare their slopes.

We can rewrite both equations in slope-intercept form, y = mx + b,

Where m is the slope of the line:

12x + 4y = 9

4y = -12x + 9

y = (-3/1)x + 9/4

12x = 36y + 48

12x - 48 = 36y

(1/3)x - 4/3 = y

The slope of the first line is -3/1, and the slope of the second line is 1/3.

Parallel lines have the same slope, so these lines are not parallel.

Perpendicular lines have slopes that are negative reciprocals of each other, meaning their slopes multiply to -1. Therefore, these lines are perpendicular.

The slope of a line is a measure of its steepness or inclination. It tells us how much the line rises or falls as we move horizontally along it.

Parallel lines will have the same slope. That means if two lines are parallel, they have the same steepness or inclination.

Here we have

Equation of the line is y = 3x --- (1)

Equation(1) is in the form y = mx + x

The slope of the line (1) = 3

Let y = m₁x + c is the line that is parallel to line (1)  

Since the slope of the parallel lines are equal

=> y = 3x + c --- (2)

Given that the line passes through (7, 1)

=> 1 = 3(7) + c

=> c = - 21 + 1

=> c = - 20  

Hence, the equation of the line is y = 3x - 20 --- (3)

It is given that the line will also pass through the point (k, 7)

=> 7 = 3k - 20
