P=x-2 ÷ x+1 for whar value of x is P equal to zero​

Answers

Answer 1

Answer:

x = 2

Step-by-step explanation:

P = [tex]\frac{x-2}{x+1}[/tex]

P will equal zero when the numerator is equal to zero , that is

x - 2 = 0 ( add 2 to both sides )

x = 2

P = 0 when x = 2

find the instantaneous rate of change of \( f(x)=4-2 x^{2} \) at \( x=0.5 \) GENERATE THE ANSWER IN 100 WORDS IT WILL BE DIVIDED INTO TWO PARAGRAPHS THE FIRST PARA WILL BE THE SUMMARY OF THE ANSWER AND SECOND PARA WILL BE THE EXPLANATION OF THE ANSWER

Answers

The instantaneous rate of change of f(x)=4-2 [tex]x^{2}[/tex] at x=0.5 is −2. This means that at that specific point, the function is changing at a rate of -2 units per unit change in x.

The instantaneous rate of change of a function at a specific point can be found by taking the derivative of the function and evaluating it at that point. In this case, we have the function f(x)=4-2 [tex]x^{2}[/tex] and we want to find the instantaneous rate of change at x=0.5.

To find the derivative of f(x), we apply the power rule for differentiation. Taking the derivative of each term, the derivative of 4 is 0, and the derivative of −2[tex]x^{2}[/tex] is −4x. Therefore, the derivative of f(x) is  (x)=−4x.

Now, to find the instantaneous rate of change at x=0.5, we substitute

x=0.5 into the derivative function. f′(0.5)=−4(0.5)=−2.

This means that the function is changing at a rate of -2 units per unit change in x.

What is the value of x?

The secant-tangent power theorem states that "if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment.

It is expressed as:

( tangent segment )² = External part of the secant segment × Secant segment.

From the given figure:

Let;

Tangent segment = 12

Secant segment = 7 + x

External part of the secant segment = 7

Plug these values into the above formula and solve for x.

( tangent segment )² = External part of the secant segment × Secant segment.

12² = 7( 7 + x)

144 = 49 + 7x

7x = 144 - 49

7x = 95

4x-3y=18 determine the missing coordinates in ordered pair

Answers

The missing coordinate in the ordered pair (5, ?) that satisfies the equation 4x - 3y = 18 is y = 2/3. Hence, the complete ordered pair is (5, 2/3).

To determine the missing coordinate in the ordered pair (5, ?) that satisfies the equation 4x - 3y = 18, we can substitute the given x-coordinate, which is 5, into the equation and solve for y.

Let's substitute x = 5 into the equation:

4(5) - 3y = 18

20 - 3y = 18

Now, we can solve for y by isolating it on one side of the equation:

-3y = 18 - 20

-3y = -2

Divide both sides of the equation by -3 to solve for y:

y = -2 / -3

y = 2/3

Therefore, the missing coordinate in the ordered pair (5, ?) that satisfies the equation 4x - 3y = 18 is y = 2/3. Hence, the complete ordered pair is (5, 2/3).

what is an example of "⊂-maximal element"?

Answers

The correct answer is a set S is T-finite if every nonempty subset X of the power set P(S) has a maximal element u, meaning there is no other element v in X such that u is a subset of v.

On the other hand, if a set S does not satisfy the condition of being T-finite, it is referred to as T-infinite.The notation "T" in this context represents Tarski, referring to the mathematician Alfred Tarski, who contributed to the study of set theory and lattice theory.In set theory, Tarski introduced the concept of T-finiteness to define a notion of finiteness for sets based on their subsets. A set S is considered T-finite if every nonempty subset X of the power set P(S) (the set of all subsets of S) has a maximal element u. This means that for any subset X, there exists an element u in X such that there is no other element v in X that properly contains u.

For example, consider the set S = {1, 2, 3}. The power set P(S) includes subsets such as {}, {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, and {1, 2, 3}. According to Tarski's T-finiteness, for any nonempty subset X from P(S), there should exist a maximal element. In this case, each nonempty subset has a maximal element because every subset has a largest element that cannot be properly contained within any other subset.

On the other hand, if a set S does not satisfy the condition of T-finiteness, it is considered T-infinite. This means that there exists a nonempty subset X of P(S) for which there is no maximal element. In other words, there are subsets within the power set that do not have a largest element.

Tarski's T-finiteness provides an alternative way to define finiteness based on the behavior of subsets within a set. It is a concept used in the study of set theory and has connections to other areas of mathematics, such as lattice theory.

Find the savings plan balance after 19 months with an APR of 11​% and monthly payments of ​$250.

Answers

To solve the savings plan balance, we have to calculate the interest for 19 months. The formula for calculating interest for compound interest is given below:$$A = P \left(1 + \frac{r}{n} \right)^{nt}$$where A is the amount, P is the principal, r is the rate of interest, t is the time period and n is the number of times interest compounded in a year.

The given interest rate is 11% per annum, which will be converted into monthly rate and then used in the above formula. Therefore, the monthly rate is $r = \frac{11\%}{12} = 0.0091667$.

The monthly payment is $PMT = $250. We need to find out the amount after 19 months. Therefore, we will use the formula of annuity.

$$A = PMT \frac{(1+r)^t - 1}{r}$$where t is the number of months of the plan and PMT is the monthly payment. Putting all the values in the above equation, we get:

$$A = 250 \times \frac{(1 + 0.0091667)^{19} - 1}{0.0091667}$$$$\Rightarrow

A = 250 \times \frac{1.0091667^{19} - 1}{0.0091667}$$$$\Rightarrow

A =250 \times 14.398$$$$\Rightarrow A = 3599.99$$

Therefore, the savings plan balance after 19 months with an APR of 11% and monthly payments of $250 is $3599.99 (approx).

Algebraic expression for 4less then 3x

Answers

When 'x' is 5, the Algebraic  expression 3x - 4 evaluates to 11.

To find the algebraic expression for "4 less than the product of 3 and some number," let's break it down step by step.

First, let's define the unknown number as 'x.' Since the problem states "the product of 3 and some number," we can express this as 3 * x or simply 3x.

Next, we want to subtract 4 from this product. The phrase "4 less than" indicates subtraction, so we subtract 4 from 3x. This can be represented as 3x - 4.

In summary, the algebraic expression for "4 less than the product of 3 and some number" is 3x - 4, where 'x' represents the unknown number.

To calculate the value of this expression for a specific value of 'x,' you substitute that value into the expression and simplify. For example, if 'x' is 5, you would substitute 5 into the expression:

3(5) - 4

This simplifies to:

15 - 4 = 11

So, when 'x' is 5, the expression 3x - 4 evaluates to 11.

In general, the algebraic expression allows us to represent a mathematical relationship between quantities using symbols and operations. By substituting specific values into the expression, we can calculate the corresponding results.

Find the least number that should be subtracted from 1456 to make a perfect square with formula

Answers

Answer:

The least number that should be subtracted from 1456 to make a perfect square with formula is 9^2, which is equal to 81.

Step-by-step explanation:

To find the least number that should be subtracted from 1456 to make a perfect square with formula, we need to use the formula for the square of a number.

(n + a)squared = nsquared + 2nas + asquared

In our case, since we want to find the least number to be subtracted, we need to make the result of the formula 2nas + asquared negative (so the difference is a perfect square)

2nas + asquared < 0

Let's try for some values of n:

1456 - n = aperfect square

1456 - 5^2 = (1456 - 25)^2 = 1431^2

1456 - 7^2 = (1456 - 49)^2 = 1407^2

1456 - 9^2 = (1456 - 81)^2 = 1375^2

Since 1375^2 is the smallest of the squares calculated so far, we can conclude that the smallest number that should be subtracted from 1456 to make a perfect square formula with a perfect square result is 1456 - 9^2 == 1456 - 81 == 9^2 == 81

So in this case, the least number that should be subtracted from 1456 to make a perfect square with formula is 9^2, which is equal to 81.

Subm

Answers

If Product X is discontinued, the company would have a monthly financial advantage of $61,600.

To determine the monthly financial advantage or disadvantage for the company if Product X is discontinued, we need to calculate the total revenue and total expenses associated with Product X.

Total Revenue:

Product X sells 15,100 units per month at a price of $21 per unit. Therefore, the total revenue can be calculated as:

Total Revenue = Number of Units Sold × Price per Unit

Total Revenue = 15,100 units × $21 = $317,100

Total Variable Expenses:

The variable expenses per unit for Product X are given as $15. Therefore, the total variable expenses can be calculated as:

Total Variable Expenses = Number of Units Sold × Variable Expenses per Unit

Total Variable Expenses = 15,100 units × $15 = $226,500

Total Fixed Expenses:

Out of the $101,000 in monthly fixed expenses, $72,000 would still be incurred even if Product X is discontinued. Therefore, the avoidable fixed expenses would be:

Total Fixed Expenses - Avoidable Fixed Expenses = $101,000 - $72,000 = $29,000

Monthly Financial Advantage (Disadvantage):

To calculate the monthly financial advantage or disadvantage, we subtract the total expenses (fixed and variable) from the total revenue:

Monthly Financial Advantage (Disadvantage) = Total Revenue - Total Variable Expenses - Total Fixed Expenses

Monthly Financial Advantage (Disadvantage) = $317,100 - $226,500 - $29,000

Monthly Financial Advantage (Disadvantage) = $61,600

Therefore, if Product X is discontinued, the company would have a monthly financial advantage of $61,600.

However, since you can't give a child a fraction of an orange, you will need to round this number to the nearest whole number.

If the decimal is less than 0.5, you round down; if it's 0.5 or greater, you round up.

You want the value of angle x° in a right triangle that has the side adjacent to x being 53 cm, and the side opposite being 26 cm.

Tangent

The tangent ratio is ...

  Tan = Opposite/Adjacent

Application

The side opposite the angle is 26 cm; the side adjacent is 53 cm. The ratio of these is ...

  tan(x) = 26/53

The arctangent function is used to find the angle when the tangent is known.

  x = arctan(26/53) ≈ 26.1°

The angle x° is approximately 26.1°.

The solution to the system of inequalities in interval notation is [-2, 1].

How to solve the system of inequalities?

Based on the information provided in the image below, we have the following system of inequalities;

-12 < 3x - 6

-3 ≥ 3x - 6

By adding 6 to both sides of the equation (inequality), we have;

-12 < 3x - 6

-12 + 6 < 3x - 6 + 6

-6 < 3x

-2 < x

x > -2 (flip)

-3 ≥ 3x - 6

-3 + 6 ≥ 3x - 6 + 6

3 ≥ 3x

1 ≥ x

x ≤ 1

Therefore, the solution to the system of inequalities is given by:

-2 < x ≤ 1

In interval notation, we have [-2, 1].

You are choosing between two health clubs club a offers membership for a fee of $13 plus a monthly fee of $28 club B offers membership for a fee of $19 plus a monthly fee of $27 after how many months will the total cost of each health club be the same? What will be the total cost for each club?

Answers

To determine when the total cost of each health club will be the same, we can set up an equation and solve for the number of months.

Let's assume the number of months is represented by 'x'.

For Club A, the total cost is given by:

Total cost of Club A = $13 (one-time fee) + $28x (monthly fee)

For Club B, the total cost is given by:

Total cost of Club B = $19 (one-time fee) + $27x (monthly fee)

To find the number of months when the total cost is the same, we set the two equations equal to each other:

$13 + $28x = $19 + $27x

Simplifying the equation, we get:

$28x - $27x = $19 - $13

$x = 6

Therefore, after 6 months, the total cost of each health club will be the same.

To find the total cost for each club after 6 months, we substitute the value of 'x' back into the equations:

Total cost of Club A after 6 months = $13 + $28(6) = $13 + $168 = $181

Total cost of Club B after 6 months = $19 + $27(6) = $19 + $162 = $181

So, the total cost for both Club A and Club B will be $181 after 6 months.

Which is an exponential decay function
F(x)= 0.2

Answers

The function F(x)=0.2F(x)=0.2 is not an exponential decay function. It is a constant function where the output value is always equal to 0.2, regardless of the input value xx.

An exponential decay function is typically in the form f(x)=a⋅bxf(x)=a⋅bx, where aa and bb are constants and bb is a value between 0 and 1. As xx increases, the exponential decay function decreases exponentially.

For example, an exponential decay function could be f(x)=0.2⋅(0.5)xf(x)=0.2⋅(0.5)x, where the base 0.50.5 represents the decay factor. As xx increases, the value of the function decreases rapidly.

In summary, an exponential decay function follows the pattern of decreasing values as xx increases, while the function F(x)=0.2F(x)=0.2 represents a constant value regardless of the input xx.

What is the domain of y = cos^-1 x?

[–1, 1]
[0, π]
Left-bracket negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction right-bracket
(–∞, ∞)

Answers

The domain cannot be (–∞, ∞) as it includes values that are not valid inputs for the inverse cosine function.

The domain of the inverse cosine function, y = cos^(-1)(x) or y = arccos(x), is the set of values for which the function is defined.

In this case, the range of the cosine function, which is the set of values that x can take, is [-1, 1]. Therefore, the domain of the inverse cosine function is the range of the cosine function.

Hence, the correct answer is [–1, 1]. This is because the inverse cosine function is only defined for values of x that fall within the range of the cosine function, which is from -1 to 1.

To clarify further, the inverse cosine function is defined as the inverse of the restricted cosine function. The restricted cosine function is defined on the interval [0, π], which means that its range is [–1, 1]. The inverse cosine function "undoes" the cosine function and maps values from [-1, 1] back to the corresponding input values in [0, π]. Therefore, the domain of the inverse cosine function is [-1, 1].

The options [0, π] and (–∞, ∞) are not correct because they do not correspond to the domain of the inverse cosine function. The range of the inverse cosine function is [0, π], and the inverse cosine function is not defined for values outside the range of the cosine function. Therefore, the domain cannot be (–∞, ∞) as it includes values that are not valid inputs for the inverse cosine function.

Answers

Answer:

  (c)  The x-intercept of f⁻¹(x) is the same as the y-intercept of f(x).

Step-by-step explanation:

You want to know the relationship between the graphs of function f(x) and its inverse f⁻¹(x).

Inverse function

The inverse of a function maps every y-value of the original function to its corresponding x-value. That is if you have ...

  f(a) = b

then the graph of f(x) contains the ordered pair (a, b).

The inverse function will have the ordered pair (b, a). That is,

  f⁻¹(b) = a

Application

If an ordered pair (x-intercept) of the inverse function is ...

  (P, 0)

Then there will be an ordered pair (0, P) on the graph of the original function. That point is the y-intercept, and its y-coordinate is the same as the x-coordinate of the x-intercept of the inverse function.

The x-intercept of f⁻¹(x) is the same as the y-intercept of f(x).

Given the diagram below, what is tan (60*)
OA. 4√2
OB. √3/2
OC. 4√3
OD. √3

Answers

Answer:

D. √3

Step-by-step explanation:

This is a 30-60-90 triangle that has special rules concerning its side lengths.Let's call the length of the side opposite the 30° angle a.The length of the side opposite the 60° angle is a * √3.The length of the 90° (right) angle is 2a.

The tangent ratio is given by:

tan (θ) = opposite/adjacent, where

θ is the reference angle.When the 60° angle is the reference angle, the side that is 8 * √3 units long is the opposite side.The side with an unknown length and opposite the 30° angle is the adjacent side.According to the 30-60-90 triangle rules, 8 is a and this is the length of the side opposite the 30° angle.

Thus, we plug in 8√3 for the opposite side and 8 for the adjacent side, which gives us:

tan (60) = (8√3) / 8

Thus reduces down to √3 so D. is the correct answer.
