The graph shows the relationship between the amount of time that a backpacker hikes and the distance traveled.

What does (5,6) represent?

What is the equation of the relationship?

Functions are expressed by writing a variable in terms of other variables known as the independent. The derivative of the given function is -3/(x-2)².

Given the function below;

f(x) = 3/x-2

Since it is a quotient, we can use the quotient rule to express the equation as shown:

let u = 3 and v = x -2

du/dx = 0 and dv/dx = 1

According to the rule;

dy/dx = (x-2)(0) - 3(1)/(x-2)²

dy/dx = 0-3/(x-2)²

dy/dx = -3/(x-2)²

Hence the derivative of the given function is -3/(x-2)²

Answer:

y = -4/3x + 12

Step-by-step explanation:

y - y1 = m (x - x1)

the y1 and x1 are where your coordinates go. The m is the slope.

So now we just plug it in.

y - (-4) = -4/3 (x - 12)

we can clean it up some more to make it into the y = mx + b format.

y + 4 = -4/3x - (-4/3)12

y + 4 = -4/3x + 16

y = -4/3x + 12

The swimming pool will take 135850 seconds to fill with water.

Given the dimensions of the pool are:

7.15 m

21 m

1.9

The swimming pool is being filled with water at a constant rate of 2.1 liters per second.

hence the volume of the swimming pool is :

volume = 7.15 × 21 × 1.9

volume = 285.285 m³

convert from meters to liters.

volume = 285.285 × 1000

= 285285 liters.

to find out the time required to fill the pool, we need to divide the volume by the flow rate.

⇒ 285285 ÷ 2.1

= 135850

If the median of 6 consecutive integers is 9, the largest number is equal to 8.5.

Given the following data:

In Mathematics, a median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.

In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.

For the largest number, we have:

Since consecutive integers must follow each other sequentially with a difference of 1, so the largest number is given by:

Largest number = Median + (n - 1)/2

Substituting the given parameters into the formula, we have;

Largest number = 6 + (6 - 1)/2

Largest number = 6 + (5)/2

Largest number = 6 + 2.5

Distance, D = 5,760,000/2,160 = 2666.67 (approx)

The Excel DATE/TIME capabilities include the TIME Function. We can construct a time using distinct hour, minute, and second components with the aid of TIME.

We might want to date a report while performing financial analysis. In these circumstances, TIME can be used to transform a text string into a format that indicates the time in decimal form. Additionally, the function can be used to combine different values into a single time value.

formula= TIME (hour, minute, second)

distance = rate X time

D = RT

T = D/R

20 feet per second = 1200 feet per minute

16 feet per second = 960 feet per minute

[of minutes to flowerbed] + 14 minutes + [of minutes back to hive] = 19 minutes

(D/R) + 14 + (D/R) = 19

(D/R) + 14 + (D/R) = 19

(D/1200) + 14 + (D/960) = 19, This is the equation we can use to find the distance from the flowerbed to the​ hive.

(D/1200) + (D/960) = 5

(D(1200)(960))/1200 + (D(1200)(960))/960 = 5(1200)960

960D + 1200D = 5(1200)960

Step-by-step explanation:

The charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, and 7 six-cylinder will be $2313.25.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that charges per oil change are $33.95, charges for a four-cylinder engine $72.50, charges for a six-cylinder engine $82.50, and, charges for an eight-cylinder engine $92.50.

The total charges will be calculated as below:-

No oil changes done by Charlene = 35

price of 5 - four-cylinder engines = 5 × 72.50

= 362.50                                .....(1)

Price of 7 - six cylinder engines = 7 × 82.50

= 577.50                                ........(2)

Price of 2 - eight-cylinder engines = 2 × 92.50

= 185                                       ...........(3)

Now, adding (1), (2),(3)

= 362.50 + 577.50 + 185

= 1125                                        ...........(4)

Total charges for oil = 33.95 × 35

= 1188.25                                  ..........(5)

Add equations (4) and (5) to get the total charges.

= 1125 + 1188.25

= 2313.25

Therefore, the total charges will be $2313.25.

The complete question is given below:-

Charlene operates an oil change and tune-up service. she charges $33.95 per oil change. a tune-up is $72.50 for a four-cylinder engine, $82.50 for a six-cylinder engine, and $92.50 for an eight-cylinder engine. what are the charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, and 7 six-cylinder?

Pascal's triangle is the triangular array of numbers that begins with 1 on the top and with 1's running down the two sides of a triangle.

The tip of the triangle starts with 1 and the 1 starts continuing to both the ends of the triangle in each row and in between there is the sum.

For example:

                  1

                1   1

             1    2   1

         1   3    3     1

In the above manner, it continues.

now, for 10 rows the pascal triangle will be:

                       1

                     1   1

                  1    2   1

              1   3    3     1
