The required values are a = 7, b = -2, and c = -4 to make the given expression equivalent to the given expression.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Consider expression.

3x/(x+2) + 4x/(x-2)

To begin, we factor out an x from both numerators:

3x/(x+2) + 4x/(x-2) = x(3/(x+2) + 4/(x-2))

Then, factor out a common denominator from the two terms in the parentheses:

x(3/(x+2) + 4/(x-2)) = x((x-2)(3/(x+2)) + (x+2)(4/(x-2)))

Then, we can expand and simplify:

x((x-2)(3/(x+2)) + (x+2)(4/(x-2))) = (7x² - 2x)/(x² - 4)

Therefore, we can set a = 7, b = -2, and c = -4 to make the given expression equivalent to the given expression.

The conductance of a conductor is inversely related to the cross-sectional area of the conductor.

Conductance is directly related to the ease offered by any material to the passage of electric current. Conductance is the opposite of resistance. The higher the conductance, the lower the resistance, and vice versa, the greater the resistance, the less conductance, so both are inversely proportional

Which of the following describes the relationship of conductance to a conductor?

The conductance of a conductor is directly proportional to the length of the conductor.

The conductance of a conductor is directly proportional to the cross-sectional area of the conductor.

The conductance of a conductor is inversely proportional to the square of the length of the conductor.

Answer: (-b + a, b + a).

Step-by-step explanation:

To find the radius of convergence of the series, we use the formula:

R = 1/limsup|bn|^(1/n)

To find the interval of convergence, we can use the following:

If R > 0, the series converges for all |x-a| < R and diverges for |x-a| > R.

If R = 0, the series converges only at x = a and diverges for all other values of x.

If R = ∞, the series converges for all values of x.

Therefore, the interval of convergence of the series is (-R + a, R + a).

In this case, the radius of convergence R is given as b, and the interval of convergence is (-b + a, b + a).

Step-by-step explanation:

The amount of markup if markup to 40% is nullified by giving some discount of Rs. 980 is Rs 280.

The markup, expressed as a percentage of cost, is the difference between a product's selling price and its cost.

The markup of 40%

Let's Assume the cost price = Rs 100C

Calculate the markup as shown below,

Mark up = (40 / 100) 100C = Rs 40C

Marked price = 100C + 40C = Rs 140C

Hence, 140C = 980

C = 7

Thus, markup price = 7 × 40 = Rs 280

Therefore, the amount of markup if markup to 40% is nullified by giving some discount of Rs. 980 is Rs 280.

The Quadratic form is (x² - 1)(x² - 9) = 0 and the value of x is {1, -1, 3, -3}.

What is Quadratic form ?

In mathematics, a polynomial with all terms of degree two is called a quadratic form.

Given, x^4-10x^2+9=0

here, a + b = -10

and, ab = 9

So, a = -1 and b = -9

So, It can be written in Quadratic form as :

(x² - 1)(x² - 9) = 0

Now, we can solve as follows:

       x² - 1 = 0                         and,    x² - 9 = 0

      (x+1)(x-1) = 0                              (x+3)(x-3)=0

The profit is Rs. 200.

The pricing system in which a commodity's (goods or services') price is lower than its listed price is referred to as a "discount." Simply put, "discount" refers to a percentage of the advertised price. A discount is a type of price reduction on products that is seen in consumer transactions. In these transactions, buyers propose a percentage of rebates on various products to increase sales. A discount is the seller's offer of a discount to the buyer.

Given marked price = Rs. 800

discount % = 10%

discount = 10% of 800

discount = 800 x 0.1 = 80

selling price = marked price - discount

selling price = 800 - 80 = Rs. 720

The dealer makes a profit of 20% means is selling the article at 120%.

120%=720

1%=6

Hence, 100%=600

Thus, the cost price of article= 600

Together, Phillip and Jody have 20 + 40 = 60 tropical fish.

We know that Phillip has twice as many tropical fish as Jody, so Phillip has 2x tropical fish.
We also know that after giving Jody 10 tropical fish, Phillip would have half as many as Jody, so 2x - 10 = x/2.

Solving for x, we get:

The simple interest is 7% per year.

Simple interest is the borrowing amount added only to the principal amount.

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is principal amount, T is time period and R is interest rate in a year.

Given:

Kevin invests money in an account paying simple interest.

He invests $40 and no money is added or removed from the investment. After one year, he has $42.80.

That means,

A = $42.80, P = $40, T = 1 year.

So,

R =(1/T) (A/P - 1)

R = (1/1)((42.8/40) - 1) = 0.07

R = 0.07

Step-by-step explanation:

The value of x, here x is non-negative integer (i.e x> 0) is equals to the eight.

We have, the vertices of a triangle are (0, 0), (x, 2x), and (x, 0), where x > 0 .

Area of triangle formed by those vertices = 64 square units . The area of the triangle whose vertices are (x₁ , y₁) ,( x₂ , y₂) and (x₃ , y₃) is 1/2 ∣x₁(y₂ - y₃) + x₂( y₃ - y₁) + x₃ (y₁ - y₂)|.

Comparing the vertices (0, 0), (x, 2x), and (x, 0) with standard vertices (x₁ , y₁) ,( x₂ , y₂) and (x₃, y₃). We get, x₁ = 0 , y₁ = 0 , x₂

= x , y₂ = 2x , x₃ = x and y₃ = 0.

Now, the area of the triangle is equals to

1/2 ∣0(2x - 0) + x( 0 - 0) + x (0 - 2x)| = 64

=> 1/2| 0 + 0 + (-2x)x| = 64

=> 1/2 | - 2x²| = 64

=> 1/2(2x²) = 64

=> x² = 64

=> x = ±√64

=> either x= - 8 or x = 8 , but x > 0

So, value of x is 8.

If the reaction is first order in A, the rate law is rate = k[A], where k is the rate constant. Since the rate of the reaction is 1.6 x 10⁻³ M/s and the concentration of A is 0.11 M, we can find the value of the rate constant by plugging in the given values:

1.6 x 10⁻³ M/s = k(0.11 M)

Solving for k:

k = (1.6 x 10⁻³ M/s) / (0.11 M) = 14.55 x 10⁻⁴ s⁻¹

So the rate constant for a first order reaction in A is 14.55 x 10⁻⁴ s⁻¹.

If the reaction is second order in A, the rate law is rate = k[A]², where k is the rate constant. Since the rate of the reaction is 1.6 x 10⁻³ M/s and the concentration of A is 0.11 M, we can find the value of the rate constant by plugging in the given values:

1.6 x 10⁻³ M/s = k(0.11 M)²

Solving for k:

k = (1.6 x 10⁻³ M/s) / (0.11 M)² = 0.1395 x 10⁻³ M⁻¹ s⁻¹

As they are symmetric around the graph's origin, cosine and secant are even functions.

This indicates that the resulting graph will be identical to the original graph if you reflect it around the x-axis. This is due to the fact that sec(x) = sec(-x) and cos(x) = cos(-x).

Because their values are the same for both positive and negative angles, the cosine and secant functions are even. This indicates that the cosine and secant of any given angle will be identical to one another for any given angle, as will the cosine of that angle and the secant of that angle.

B) In this case the percent increase is 43.6%

We can find the percent increase using the following formula:

Here we know that:

final price = $345

Initial price = $225

Then the percent increase is:

100%*($345 - $225)/$225 = 100%*0.533 = 53.3%

So the price of the ticket increased by 53.3%
