Step-by-step explanation:
find dy/dx by implicit differentiation. y sin(x2) = x sin(y2)
The derivative dy/dx of the equation ysin(x^2) = xsin(y^2) is given by (sin(y^2) - ycos(x^2)2x) / (sin(x^2) - 2yxcos(y^2)).
In the given equation, y and x are both variables, and y is implicitly defined as a function of x. To find dy/dx, we differentiate each term using the chain rule and product rule as necessary.
Differentiating the left-hand side of the equation, we apply the product rule to ysin(x^2). The derivative of ysin(x^2) with respect to x is dy/dxsin(x^2) + ycos(x^2)*2x.
Differentiating the right-hand side of the equation, we apply the product rule to xsin(y^2). The derivative of xsin(y^2) with respect to x is sin(y^2) + x*cos(y^2)2ydy/dx.
Now we have two expression for the derivative of the left and right sides of the equation. To isolate dy/dx, we can rearrange the terms and solve for it.
Taking the derivative of ysin(x^2) = xsin(y^2) with respect to x using implicit differentiation yields:
dy/dxsin(x^2) + ycos(x^2)2x = sin(y^2) + xcos(y^2)2ydy/dx.
By rearranging the terms, we can solve for dy/dx:
dy/dx * (sin(x^2) - 2yxcos(y^2)) = sin(y^2) - y*cos(x^2)*2x.
Finally, we can obtain the value of dy/dx by dividing both sides by (sin(x^2) - 2yxcos(y^2)):
dy/dx = (sin(y^2) - ycos(x^2)2x) / (sin(x^2) - 2yxcos(y^2)).

An item sells for $75 and is on sale for 35% off. The sales tax is 9.8%. What is the final cost of the item?
The final cost of the item after a 35% discount and 9.8% sales tax is $53.54.
The given problem is related to percentage discounts and sales tax and can be solved using the following steps:
Step 1: Firstly, we need to determine the discount amount, which is 35% of the original price. Let's calculate it. Discount = 35% of the original price = 0.35 x $75 = $26.25
Step 2: Now, we will calculate the new price after the discount by subtracting the discount amount from the original price.New Price = Original Price - Discount AmountNew Price = $75 - $26.25 = $48.75
Step 3: Next, we need to calculate the amount of sales tax. Sales Tax = 9.8% of New Price Sales Tax = 0.098 x $48.75 = $4.79
Step 4: Finally, we will calculate the final cost of the item by adding the new price and the sales tax.
Final Cost = New Price + Sales Tax Final Cost = $48.75 + $4.79 = $53.54
Therefore, the final cost of the item after a 35% discount and 9.8% sales tax is $53.54.I hope this helps!

The marginal cost of producing one more unit of the product when x = 100 is $150 per unit. To find the instantaneous rate of change (or the marginal cost) of c with respect to x when x = 100, we need to calculate the derivative of the cost function c(x) with respect to x and evaluate it at x = 100.
Let's assume that we have the cost function c(x) = 0.5x^2 + 50x + 1000, where x is the number of units produced. To find the derivative of this function, we need to use the power rule of differentiation, which states that if f(x) = x^n, then f'(x) = nx^(n-1). Applying this rule to our cost function, we get:
c'(x) = d/dx (0.5x^2 + 50x + 1000)
= 1x^(2-1) + 50x^(1-1) + 0
= x + 50
Now, we can evaluate this derivative at x = 100 to find the marginal cost:
c'(100) = 100 + 50
= 150
Therefore, the marginal cost of producing one more unit of the product when x = 100 is $150 per unit. This means that if the company produces one more unit of the product, it will cost them $150 more than the cost of producing the previous unit. The significance of the marginal cost will be explained in a future chapter, but for now, it is important to understand that it is a crucial concept in economics and business decision-making.

Test for relative maxima and minima. Use the second-derivative test, if possible. \[ y=x^{3}-12 x+3 \] Select the correct choice below and, if necessary, fill in the answer box(es) to complete your ch
In this the correct choice is: D. There are no relative maxima and no relative minima.
The given function is y = \(x^{3}\) - 12x + 3. To find the relative maxima and minima, we need to calculate the first and second derivatives of the function.
First, let's find the first derivative: y' = 3\(x^{2}\) - 12
Now, let's find the second derivative: y'' = 6x
To apply the second-derivative test, we need to determine the critical points by setting the first derivative equal to zero and solving for x:
3\(x^{2}\) - 12 = 0
\(x^{2}\)- 4 = 0
(x - 2)(x + 2) = 0
From this equation, we find that x = 2 and x = -2 are the critical points.
Now, let's evaluate the second derivative at these critical points:
y''(2) = 6(2) = 12
y''(-2) = 6(-2) = -12
Since the second derivative at x = 2 is positive (12 > 0) and the second derivative at x = -2 is negative (-12 < 0), the second-derivative test tells us that there are no relative maxima or minima. Therefore, the correct choice is D. There are no relative maxima and no relative minima for the given function.

a country's postal service will accept a package if its length plus its girth (the distance all the way around) does not exceed 72 inches. find the dimensions (in inches) and volume (in cubic inches) of the largest package with a square base that can be mailed.
The length of the package is 32 inches and the width and height of the package are 16 inches each.
The volume of the package is 8192 cubic inches.
(a)
Assume that the length is y in and that the width and height be equal to x in as the base is a square.
Therefore,
The girth is 4*x = 4x inches
The maximum sum of length and girth is 72.
So, according to the equation:
y + 4x = 72
Subtracting 4x from each side of the equation,
y + 4x - 4x = 72 - 4x
y = 72 - 4x
The following formula can be used to determine the package's volume:
Volume = length × width × height
Volume = y × x × x
Volume = x²y cubic inches
Substituting the values in the above equation,
Volume = x² ( 96 - 4x )
Volume = 96x² - 4x³ cubic inches
The volume will be maximum when dV / dx = 0.
So,
dV/dx = d/dx ( 96x² - 4x³ ) = 0
2(96)x - 4(3)x² = 0
192x - 12x² = 0
x( 192 - 12x ) = 0
So, x = 0 which is not possible.
or
192 - 12x = 0
Adding 12x on each side of the equation.
192 = 12x
Dividing each side of the equation by 12.
x = 16 inch
Now substituting this value in y = 96 - 4x.
y = 96 - 4x
y = 96 - 4(16)
y = 96 - 64
y = 32 inch
(b)
The volume of the package = length × width × height
volume = 32 × 16 × 16
volume = 8192 cubic inches

and always will do. in his book euclid says this is self-evident. you see there it is even in that 2000 year old book of mechanical law it is the self-evident truth that things which are equal to the same things are equal to each other."
explain how this common notion is an example of a postulate or a theorem
The statement made by Lincoln in the movie "Lincoln" refers to a mathematical principle known as Euclid's first common notion. This notion can be seen as an example of both a postulate and a theorem.
In the statement, Lincoln says, "Things which are equal to the same things are equal to each other." This is a fundamental idea in mathematics that is often referred to as the transitive property of equality. The transitive property states that if a = b and b = c, then a = c. In other words, if two things are both equal to a third thing, then they must be equal to each other.
In terms of Euclid's first common notion being a postulate, a postulate is a statement that is accepted without proof. It is a basic assumption or starting point from which other mathematical truths can be derived. Euclid's first common notion is considered a postulate because it is not proven or derived from any other statements or principles. It is simply accepted as true. So, in summary, Euclid's first common notion, as stated by Lincoln in the movie, can be seen as both a postulate and a theorem. It serves as a fundamental assumption in mathematics, and it can also be proven using other accepted principles.
