30 % of 500 she has to pay to the commission per week

if she made 1575 one week how much would she get?

1575 divided by 30%=472.5

472.5 rounded = 473

x=473 or 472.5

Charlotte would make $972.50 in a week in which she made $1575 in sales and  if Charlotte made x dollars in sales, she would make $500 + 0.3x in total earnings for the week.

percentage, a relative value indicating hundredth parts of any quantity.

To calculate how much Charlotte would make in a week in which she made $1575 in sales

we first need to calculate her commission:

Commission = 30% × $1575

= $472.50

Total earnings = Guaranteed salary + Commission

= $500 + $472.50

= $972.50

Therefore, Charlotte would make $972.50 in a week in which she made $1575 in sales.

To calculate how much Charlotte would make in a week if she made x dollars in sales, we can use the same method.

Her commission would be:

Commission = 30% ×x

And her total earnings would be:

Total earnings = Guaranteed salary + Commission

= $500 + 0.3x

So, if Charlotte made x dollars in sales, she would make $500 + 0.3x in total earnings for the week.

The fare for a 9-mile journey can be calculated using the formula Fare = £2.50 + £0.90 x miles. To find the fare for a 9-mile journey, we just need to substitute 9 for miles in the formula:

Fare = £2.50 + £0.90 x 9

Fare = £2.50 + £8.10

Fare = £10.60

So, the fare for a 9-mile journey would be £10.60.

It's important to understand how the formula works in order to correctly use it. The first part of the formula, £2.50, is a fixed cost that is added to the fare regardless of the distance traveled. This could represent things like the cost of hiring the taxi, the driver's time, and any other fixed expenses that the taxi company incurs.

The second part of the formula, £0.90 x miles, is the variable cost that is added to the fare depending on the distance traveled. This could represent things like the cost of fuel, wear and tear on the vehicle, and any other expenses that the taxi company incurs as a result of traveling a certain distance. By multiplying the distance traveled by the cost per mile, £0.90, the formula calculates the total variable cost for the journey.

When these two costs are added together, the formula gives the total fare for the journey. In this case, for a 9-mile journey, the total fare would be £10.60.

Given that the function of ex is ex, the derivative of y with respect to x is -14e-14x.

The rate of a function's change with regard to one of its variables is known as the derivative. The derivative of y with respect to x in the case of y=e-14x is the rate at which y varies as x changes. The derivative is the derivative of ex, which is ex because derivative  the function is e-14x. Simply multiplying ex by the coefficient of x, which is -14, yields the derivative of y with respect to x. Consequently, derivative -14e-14x is the derivative of y with respect to x. Accordingly, y will drop by 14e-14x units for every unit increase in x.

A constant function is a function that returns the same output every time it is called, regardless of the input. In this case, we want to create a constant function that returns an infinite list of all the natural numbers starting at 0.

Here's an example of how you could implement the nats function in Haskell:

makefile

Copy code

nats :: [Integer]

nats = [0..]

The [0..] syntax creates an infinite list that starts with 0 and continues indefinitely. Every time the nats function is called, it returns this same infinite list, so it's considered a constant function.

Another way to write the nats function is to use the iterate function, which generates a list by repeatedly applying a function to an initial value.

makefile

Copy code

nats :: [Integer]

nats = iterate (+1) 0

In this case, iterate (+1) 0 generates a list by repeatedly adding 1 to 0. The first element of the list is 0, the second element is 0 + 1 = 1, the third element is 1 + 1 = 2, and so on. This generates an infinite list of all the natural numbers starting at 0, which is exactly what we want.

In either case, you can take any number of elements from the nats list by using the take function. For example, take 5 nats would return the first 5 elements of the nats list, which would be [0, 1, 2, 3, 4].

The Intermediate Value Theorem tell us that there is a c in the interval [0,1] such that f(c) = k is lies between f(0) and f(1).

The Intermediate Value Theorem is a fundamental concept in calculus that states that given a continuous function f and two real numbers a and b, if k is a real number between f(a) and f(b), then there exists a real number c in the interval [a, b] such that f(c) = k.

In the specific case of [0,1], the Intermediate Value Theorem tells us that if k is a real number between f(0) and f(1), then there exists a real number c in the interval [0,1] such that f(c) = k. This means that for any value of k that falls between the values of the function at 0 and 1, there is a point in the interval [0,1] where the function takes on that value.

So, for what values of k does the Intermediate Value Theorem tell us that there is a c in the interval [0,1] such that f(c) = k? The Intermediate Value Theorem tells us that there is a c in the interval [0,1] such that f(c) = k for any real number k that falls between the values of f(0) and f(1).

The flux of F coming out of the circle C is 126π.

The flux of a vector field, F, out of a surface, S, is given by the formula

Flux = ∮F •  n ds,

where n is a unit normal vector to the surface S.

In this case, the surface S is the circle C with radius 6 centered at the origin and the vector field F is given by F(x, y) = (7x, 11). We can use Green's Theorem to find the flux from the circle C. The equation for the circle is x2 + y2 = 36. Differentiating this equation with respect to x and y gives us the unit normal vector, n = (x/6, y/6).

Plugging these values into the flux formula, we get

Flux = ∮F •  n ds = ∮ (7x, 11) •  (x/6, y/6) ds

= ∮ 7x2/6 + 11y/6 ds

= (7/6) ∮ (x2 + y2) ds

The area between the graph of f and the x-axis on the interval [-8, 0] is 4608 square units.

The two-dimensional region enclosed by the function's graph and the x-axis is referred to as the region between the graph and the x-axis. Calculating the definite integral of the function over the specified interval and deducting the area below the x-axis, if any, will yield the area of this region.

There are two sections to the graph of f(x) = |x3 - 64|: a parabolic section and a linear section. The area between the graph of f and the x-axis is just the absolute value of the definite integral of f(x) over [-8, 0] because the graph of f(x) on the interval [-8, 0] is below the x-axis and contains negative values.

We must first get the antiderivative of f(x) before we can determine the definite integral, which may be accomplished by utilising partial fraction decomposition.

The antiderivative of f(x) = x⁴ - 64 is:

F(x) = (x⁴)/4 + 64x

The definite integral of f(x) over [-8, 0] is:

Area = F(0) - F(-8) = (0⁴)/4 + 64(0) - ((-8)⁴)/4 - 64(-8) = (8⁴)/4 + 64(8) = 4096 + 512 = 4608
