What is the question for this so I can answer it?

The limit as x approaches 4 of f(x) is equal to -2 * 4^2 + 3 * 4 - 1 = 15.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is defined technically as a relation between a set of inputs and a set of potential outputs, where each input is associated to exactly one output. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The limit of f(x) as x approaches 4 is given by the value of f(4).

For x = 4, the definition of f(x) is:

-2x^2 + 3x - 1 = -2 * 4^2 + 3 * 4 - 1 = 15.

Therefore, the limit of f(x) as x approaches 4 is 15.

So, lim x→ 4 f(x) = 15.

The limit of f(x) as x approaches 4 is equivalent to -2 * 42 + 3 * 4 - 1 = 15.

The required integration-by-parts formula of given function is 5x (1/6) sin(6x) - (5/36) cos(6x) + C.

To evaluate the integral using integration-by-parts, we need to find two functions u and dv such that their derivative is equal to the integrated, and such that the anti-derivative of dv can be easily found. The integration-by-parts formula states that:

∫ uv = u(v) - ∫ v du

Let's choose u = 5x and dv = cos(6x) dx. Then, du = 5 dx and v = (1/6) sin(6x).

Using the integration-by-parts formula, we get:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - ∫ (1/6) sin(6x) 5 dx

The antiderivative of (1/6) sin(6x) 5 is (5/36) cos(6x), so:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - (5/36) cos(6x) + C,

where C is the constant of integration.

The x and y-intercept for -4x+y = 8 is  (-2,0) and (0, 8)

What is the intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively. The slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y-intercept (0, b).

Here, we have

Given: -4x+y = 8

Let's start with the interception point with the x-axis. Here we know that y = 0, so we can put that in our original expression:

-4x = 8

x = -2

The function intercepts the x-axis at (-2, 0)

Let's continue with the y-axis. Here we know that  x = 0, so let's put that into our expression/function:

y = 8

This gives us an interception point with a y-axis at (0, 8)

Hence, the x and y-intercept for -4x+y = 8 is (-2,0) and (0, 8)

The time it take to paint this cone if it can be painted at the same rate is 4.21 minutes.

The region that includes the base(s) and the curved portion is referred to as the total surface area. It is the overall area that the object's surface occupies. The total area of a shape with a curved base and surface is equal to the sum of the two areas.

Given:

Base area = 49π in²

h= 8 inches

So, area of a circle, A = πr^2

r = √(A/π).

r = √(49π/π)

r = 7 in.

Now, they doubled cone has a base area

The expression that correctly represents the cost of a bag of dog food to the customer in terms of (m), the original market price is 1.5m

As per the given data Pam’s Pet Supply Palooza buys bags of dog food directly from the manufacturer.

Market Price = m

Got 50% discount off the original market price.

Discount = 50%

Pam then sells each bag of dog food at a price that is 3 times the amount that she paid for it.

Selling Price =3 × (Amount she paid)

If she gets a discount of 50 %, then she pays 50 % (100 - 50% ).

So, the amount she paid is:

Amount = 50 % × Market Price

Amount = [tex]$\frac{50}{100}[/tex] × m

Amount = 0.5 × m

Amount = 0.5 × m

She sells at three times that amount.

So, the selling price is:

Selling Price = 1.5 m

To solve this recurrence, we have to use the substitution method, where we guess a solution of the form T(n) = an^k and then prove that this is indeed a solution. This can be done by substituting the guessed solution back in to the recurrence. If the substitution works, then we have solved the recurrence.

Since Fathi has $1.10 in his printing account, he will have -$59342.28 after printing the 474747-page PDF document.

Let's calculate how much Fathi will spend on printing the 474747-page PDF document.

Since Fathi is printing 2 pages on each side of a sheet, he uses 1/2 sheet of paper per 2 pages. And since each sheet of paper reduces his printing account balance by $0.25, he will spend $0.25 per 2 pages.

So, the cost per page is $0.25 / 2 = $0.125.

Now, we can calculate the total cost of printing the 474747 pages by multiplying the cost per page by the number of pages:

$0.125 * 474747 = $59343.38

Since Fathi has $1.10 in his printing account, he will have $1.10 - $59343.38 = -$59342.28 after printing the 474747-page PDF document.

The area of the region between the curves y=sinx and y=cosx that contains the point (0,0) is 4π.

The area of the region between the curves y=sinx and y=cosx that contains the point (0,0) is the integral of the absolute value of the difference between the two functions. This is expressed mathematically as:

∫|sinx-cosx|dx

Using integration by parts, we can break this integral into two parts:

∫sinx dx - ∫cosx dx

Integrating each of these parts separately and substituting in the limits of integration from 0 to 2π, we get the following:

2π - 0 - (-2π)

Simplifying, this gives us the area of the region as 4π.

Therefore, the area of the region between the curves y=sinx and y=cosx that contains the point (0,0) is 4π.

Differentiation is a mathematical technique used to calculate the instantaneous rate of change of a function based on one of its variables. Velocity, or how quickly a distance varies in respect to time, is the most common example. Differentiation's opposite is finding an antiderivative.
