Because we want the revenue to be a function of x, we must express the price and quantity in terms of x. The number is straightforward; it is x.If x is the number of units sold, we will refer to these two functions as: R(x) denotes the revenue function, while C(x) denotes the cost function. As a result, our profit function equation will be: P(x) = R(x) - C (x).Profit is a function. P(x) is the profit made from selling x units of the commodity and is represented by the difference.

A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain.

The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range.

The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A->B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output.

A -> 2B rateB =__________________ M/s

Answers

The rate of B is  -0.003072 M/s.

The average rate of change is a measure of how much a quantity changes over a certain period of time. In this case, we are looking at the concentration of B, and we want to know how much it changes over the time interval from 0 to 332 seconds. To calculate this, we first need to determine the initial and final concentrations of B at these two points in time.

From the given data, we know that

the initial concentration of B at t = 0 is 0.670 Mthe final concentration of B at t = 332 s is 0.160 M.

Once we have these values, we can calculate the change in concentration of B by subtracting the initial concentration from the final concentration: 0.160 M - 0.670 M = -0.510 M. This tells us that the concentration of B decreases by 0.510 M over the time interval from 0 to 332 seconds.

Next, we need to divide this change in concentration by the length of the time interval to get the average rate of change. The length of the time interval is the difference between the final and initial time: 332 s - 0 s = 332 s. So, the average rate of change of B is (-0.510 M) / (332 s) = -0.001536 M/s. This tells us that the concentration of B decreases by 0.001536 M per second on average over the given time interval.

As we know that the reaction is of form A -> 2B, the rate of formation of B is equal to twice the rate of A.

So, Rate of B = 2* Rate of A =  2*(-0.001536) = -0.003072 M/s

Find one of the two possible correct answers. Enter a number for y only!

Hint: Substitute numbers in for x and y and find a pair that works!

y = ____

Answers

Step-by-step explanation:

we can do even a little bit better than wild guessing and trying.

3x + 2y = 13

tells us that the sum of 2 terms is an odd number.

that means one term has to be odd and the other even, as only then their sum will be odd.

2y is because of the included factor 2 an even number. always.

so, 3x has to be odd.

and that means x has to be odd too. because an even number multiplied with any number is always even.

so, x can only be 1 or 3. because 3×5 = 15 (3×7 = 21, 3×9 = 27) and already too big for the sum 13.

so, for x = 1 we have

3×1 + 2y = 13

3 + 2y = 13

2y = 10

y = 5

for x = 3 we have

3×3 + 2y = 13

9 + 2y = 13

2y = 4

y = 2

so, the answer is either y = 2 or y = 5.

A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

here, the equation is -

y=7.25x

x = 325

y = 2356.25
