(-1,1) and (1,5) write your answer in slope-intercept form

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

         x = ±1                           and, x = ±3

∴ Value of x = {1, -1, 3, -3}

The final temperature of the mixture is approximately 4.2°C.

1. Calculate the total heat capacity of the calorimeter:

Heat capacity = Mass x Specific heat capacity of water = 1.0 kg x 4.18 J/g°C = 4180 J/°C

2. Calculate the heat lost by the water:

Heat lost = Mass of water x Specific heat capacity of water x (T_final - T_initial)

= 1.0 kg x 4.18 J/g° C x (4.2°C - 20°C)

= -41360 J

3. Calculate the heat gained by the ice:

Heat gained = Mass of ice x Specific heat capacity of ice x (T_final - T_initial)

= 1.0 g x 2.09 J/g° C x (4.2°C - 0°C)

= 8.36 J

4. Calculate the final temperature of the mixture:

Jody has 20 tropical fish and Phillip has 2x = 2*20 = 40 tropical fish.
Together, Phillip and Jody have 20 + 40 = 60 tropical fish.

Let x be the number of tropical fish Jody has.
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:
x = 20

So Jody has 20 tropical fish and Phillip has 2x = 2*20 = 40 tropical fish.
Together, Phillip and Jody have 20 + 40 = 60 tropical fish.

A) In the first case where we don't count the baggage fee, the percent increase is 53.3%

B) In this case the percent increase is 43.6%

We can find the percent increase using the following formula:

100%*(final price - initial price)/initial price

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%

b) If we also count the $50 for the baggage fee with the new ticket price, then the increase is:

100%*($345 + $50 - $225 - $50)/($225 + $50) = 100%*0.436 = 43.6%

Where the $50 fee would be counted on the initial and final price, that is why it appears twice.

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 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

She can generate one of 30 results by tossing a coin, rolling a fair die with six sides labeled 1 through 6, and spinning a spinner with multiple equal-sized sections marked Walk, Run, and Stop.

We only apply the basic concept of counting. According to this rule, the number of options for both occurrences is equal to p x q if there are p possibilities once per event as well as q possibilities for just a second event. This formula can be expanded to include more events.

Let's say there are p possible outcomes when a coin is flipped based on the information provided. Therefore, p=2 because there are two alternative results, heads or tails.

Let q represent the result of a fair die that is shaped like a six-sided cube.

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. They are useful for a wide range of tasks because of this property, such as resolving differential equations and working with periodic functions.

The acute angle of a triangle is an angle that measures less than 90°. Hence, in the triangle ABC, an acute angle is any angle that is smaller than 90°.

An angle is the figure created by two rays whose termini coincide. The measure of an angle is the amount of rotation required to bring one ray onto the other. A degree or angle that is less than 90° is said to be acute. This means that the two rays forming the angle can be brought together without making a full rotation.

A right angle is an angle having a measurement of precisely 90°. A right angle is formed when the two rays are perpendicular to each other, meaning they form a 90-degree angle. A right angle is often symbolized with a small square at the angle's vertex.

If an angle measures more than 90°, it is called an obtuse angle. An obtuse angle is formed when the two rays forming the angle can be brought together by making more than one full rotation. Obtuse angles are larger than right angles, but smaller than straight angles (which measure 180°).

It's important to note that the terms "acute," "right," and "obtuse" are not just limited to angles. They can also be used to describe other geometric shapes, such as triangles and circles. In these cases, the definitions may vary slightly, but the basic concept remains the same.

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 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)

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).
