27. a parallelogram has three of its vertices at (-1, 0), (2, 4) and (2, -4). what is the positive difference between the greatest possible perimeter and the least possible perimeter of the parallelogram?

Answer: The smallest number that can be divided by 90, 80 and 72 without a remainder is 720.

Step-by-step explanation:

To find the smallest number that can be divided by 90, 80, and 72 without a remainder, you can find the least common multiple (LCM) of 90, 80, and 72. The LCM is the smallest positive number that is a multiple of all the given numbers.

One way to find the LCM is to list out the multiples of each number and then find the smallest one that is common to all.

Multiples of 90: 90, 180, 270, 360, 450, 540, 630, 720, 810, 900, 990, 1080, 1170...

Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880, 960, 1040, 1120...

Multiples of 72: 72, 144, 216, 288, 360, 432, 504, 576, 648, 720, 792, 864, 936, 1008...

As you can see 720 is the smallest common multiple for all the numbers 90,80 and 72. Therefore, the smallest number that can be divided by 90, 80, and 72 without a remainder is 720.

The equation of the quadratic function whose zeros are 3 and 5 is x² - 8x + 15 = 0

The term equation in math is known as a mathematical statement that is made up of two expressions connected by an equal sign

Here we have the zeros are 3 and 5.

As we all know that the quadratic polynomial can be expressed using its zeros as follows,

=> x² - (α + β)x + (αβ) = 0

Here we know the values of α = 3 and the value of β = 5.

Now, we have to apply the value on the equation, then we get,

=> x² - (3 + 5)x + (3 x 5) = 0

When we simplify this then we get the expression,

=> x² - 8x + 15 = 0

The domain of the quadratic function is represented by all the numbers on the number line, which is the set of values for which the function is defined.

A function is a mathematical rule or procedure that takes an input, performs a specific operation, and produces an output. In programming, functions are blocks of code that are designed to perform specific tasks. They are used to break down complex problems into smaller, manageable parts, and to make code more organized, readable, and reusable. Functions can also be used to share code between multiple programs.

The best way to determine the domain of a quadratic function is to identify the range of values for which the function is defined. The domain of a quadratic function is typically composed of all real numbers, which can be represented by the set of all numbers on a number line. In the graph of the quadratic function, the set of points on the graph represents the range of values for which the function is defined. Therefore, the domain of the quadratic function is represented by all the numbers on the number line, which is the set of values for which the function is defined.

The points of solution that are obtained for the system of linear equations 3x + 2y = 11 and -8x - 4y = -20 are (-1,7).

2(3x + 2y = 11)

1(-8x - 4y = -20)

3x + 2y - 8x - 4y = 11 - 20 gives -5x - 2y = -9

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The system of linear equations are -

3x + 2y = 11....(1)

-8x - 4y = -20....(2)

When solved initially the value of equation is -

3x + 2y - 8x - 4y = 11 - 20

-5x - 2y = -9

Multiply equation (1) by 2 -

2(3x + 2y) = 2 × 11

6x + 4y = 22.....(3)

Simplify the equation (2) and (3) by adding -

-8x - 4y + 6x + 4y = -20 + 22

-2x = 2

x = -1

Substituting the value of x = -1 in equation (1) -

3x + 2y = 11

3(-1) + 2y = 11

Simplifying the equation -

-3 + 2y = 11

2y = 11 + 3

2y = 14

y = 7

Therefore, the final value is obtained as (-1,7).

The required value of k the following pair of equations has no solution is k = 2.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

3x + y -1 = 0

(2k -1)x + (k-1)y - 2k -1 = 0

A1/A2 = 3(2k -1); B1/B2 = 1/(k-1); and C1/C2 = -1/(-2k -1) = 1/(2k +1).

as there are none

A1 = B1 + B2 = C1 + C2

3/(2k-1) = 1/(k -1) ≠ 1/(2k +1)

3/(2k –1) = 1/(k -1) (k -1)

3k -3 = 2k -1

k =2

Answer:

f(0)=-5

f(2)=3

f(-2)=-15

f(4)=11

f(-1)=-9

Step-by-step explanation:

Pretty simple once it clicks.You just need to substitute the x in f(x). So f(2) is just replacing the x in the equation. We would get 4*2-5. This would get us 8-5 which is 3. So rule of thumb, just substitute the x.

We can start by using the following formula to find the original price:

Original price = Sale price / (1 - (Discount percentage / 100))

To use this formula, we need to convert the discount percentage from 18% to a decimal. We can do that by dividing 18 by 100.

Discount percentage as decimal = 18 / 100 = 0.18

Now we can use this value in the formula:

Original price = $522.75 / (1 - 0.18) = $522.75 / 0.82 = $638.57

So the original price of the television set was $638.57.

Rounding to the nearest cent, the original price of the television set is $638.57

We have to given that;

The polynomial p is a function of x with 4 zeros are -4, -2/3, 0 and 9.

Now, We can formulate;

The polynomial is,

⇒ p (x) = (x - (-4)) (x - (-2/3)) (x - 0) (x - 9)

⇒ p (x) = (x + 4) (x + 2/3) (x) (x - 9)

⇒ p (x) = x (x + 4) (x - 9) (x + 2/3)

⇒ p (x) = x (x² - 9x + 4x - 36) (x + 2/3)

⇒ p (x) = x (x² - 5x - 36) (x + 2/3)

⇒ p (x) = x (x³ + 2/3x² - 5x² - 10/3x - 36x - 24)
