Answer: 16 for number 1 and 15 for number 2

Step-by-step explanation: 24 divided by 8 is 3 meaning we have to multiply 8 by 2 to get the upper part if the fraction 2 times 8 is 16

24 divided by 8 is 3 so we multiply 5 by 3 to get 15

Yes, in this situation is it possible that lim x → 1 f(x) exists.

A horizontal/vertical oblique line that approaches 0 but never reaches it is known as an asymptote. Its distance from the graph of the function keeps becoming smaller.

What's the vertical asymptote rule?

Vertical asymptotes happen when a factor from a rational expression's denominator does not cancel out with a factor from the numerator.

                        The existence of a vertical asymptote occurs when a factor does not cancel, as opposed to creating a hole at that number. Using a dotted vertical line, the vertical asymptote is shown.

if f(x) has a vertical asymptote at x = 1,

it can be defined such that lim x→1− f(x) = 6,

lim x→1+ f(x) = 3,

and lim x→1 f(x) exists.

The function (f - g)(x) is given as follows:

C. (f - g)(x) = |7x + 1| - 6.

The functions for this problem are defined as follows:

To obtain the subtraction of f(x) by g(x), we merely subtract the definitions, as follows:

(f - g)(x) = f(x) - g(x).

Hence:

(f - g)(x) = |7x + 1| - 8 - (-2)

(f - g)(x) = |7x + 1| - 8 + 2.

The like terms in the expression are given as follows:

-8 + 2 = -6.

Hence the subtraction function for this problem is defined as follows:

(f - g)(x) = |7x + 1| - 6.

The expression (x - 10)(60 - 3x) represents Elliot's profit based on the price per key chain, where x is the price in dollars that Elliot charges for each key chain.

The expression can be interpreted as follows:

x - 10 represents the revenue Elliot makes from each key chain, as it's equal to the price per key chain minus the cost of materials for each key chain.

60 - 3x represents the number of key chains Elliot can make and sell, as it's equal to the maximum amount of money Elliot has minus the total cost of materials for all key chains.

So, (x - 10)(60 - 3x) represents Elliot's total profit, which is equal to the revenue from each key chain multiplied by the number of key chains Elliot can make and sell.

In other words, Elliot's profit is proportional to both the price he charges per key chain and the number of key chains he can sell at that price. The expression captures this relationship and can be used to determine Elliot's profit for different prices.

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 value of p(0) is the same as the value of q(0) since p and q are both polynomials.

Polynomials are mathematical expressions that are composed of variables and constants and involve only non-negative integer powers of the variables. In this case, p and q are both polynomials. This means that they have the same degree, or highest power of the variable, and the same coefficients. As a result, p(0) will have the same value as q(0). To find the value of p(0), substitute 0 into the function for p. This will give the value of p(0). For example, if p(x) = 3x2 + 2x + 1, then p(0) = 3(0)2 + 2(0) + 1 = 1. This means that p(0) = 1.

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).

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 slope of this graph is equal to 8/50 or 0.16.

In Mathematics, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Based on the information provided, we can logically deduce the following slope and data points on the line:

Substituting the given points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (29.00 - 5.00)/(150 - 0)

Slope, m = 24/150

Yes it's linear because the rate of change between x and y remain the same. Every increase of 5 in x results in a decrease of 4 in y, as example from x0 to x5, y goes from 18 to 14, from x5 to 10, y goes from 14 to 10. They decide to double the jump and go from x10 to x20, but as proof of it being linear, y also double the amount it decreases going from 4 to 8.

The that shows how Jane can rewrite the formula to find the equivalent semi-annual interest rate is Option (a)  A ≈ [tex]1500(1.095)^{2t}[/tex].

The formula [tex]1500(1.2)^t[/tex] shows the amount Jane will have to pay after t years if the loan is compounded annually at an interest rate of 20%. To find the equivalent semi-annual interest rate, we need to rewrite the formula so that it represents the amount she would have to pay if the interest was compounded semi-annually.

First, let's find the equivalent semi-annual interest rate. If the annual interest rate is 20%, the semi-annual interest rate would be:

[tex]r = 20\% / 2 = 10 \%[/tex]

Next, let's raise (1 + r) to the power of 2 to find the equivalent annual interest rate when compounded semi-annually:

[tex](1 + r)^2 = (1 + 10\%)^2 =( 1.1)^2 = 1.21[/tex]

So, the equivalent annual interest rate when compounded semi-annually is 21%.

Finally, let's substitute the equivalent semi-annual interest rate into the formula to find the amount Jane would have to pay if the interest was compounded semi-annually:

[tex]A = 1500(1 + r)^{2t} = 1500(1.095)^{2t}[/tex]

So, the equation that shows how Jane can rewrite the formula to find the equivalent semi-annual interest rate is:

A ≈ [tex]1500(1.095)^{2t}[/tex]

This equation represents the amount Jane would have to pay after t years if the loan is compounded semi-annually at an interest rate of 21%.

Answer: To find the roots of a polynomial equation, we can use various methods, such as factoring, synthetic division, or the quadratic formula. One common method to find the roots of a quartic polynomial (degree 4) is to use the factor theorem, which states that if a polynomial equation has a root "r", then "r" is a factor of the polynomial.

In this case, we can factor 2x^4-26x^2-28 as:

2x^4 - 26x^2 - 28 = 2(x^2 - 7)(x^2 + 4)

So, the roots of 2x^4-26x^2-28 are x = ±√7 and x = ±i√2.

These are the solutions to the equation 2x^4-26x^2-28 = 0.

Giselle can play at most 6 games in the 6 hours she has available, which meets her second condition but not her first.

To determine the maximum number of games Giselle can play, we need to balance the time available with the number of games she wants to play. Let's assume that each game takes x hours to complete.

Condition a: 10 games = x * 10

Condition b: 6 hours = x * 10

From these two equations, we can solve for x, which represents the time it takes for Giselle to play one game. To do this, we'll divide both sides of the first equation by 10:

10 games / 10 = x * 10 / 10

x = 1 hour

So, it takes Giselle 1 hour to play one game. Knowing this, we can determine how many games she can play in the 6 hours she has available:
