Explanation:

A rhombus is a parallelogram in which the diagonals are mutual perpendicular bisectors. The coordinates of the vertices can be used to show ...

When both these conditions are met, the quadrilateral is a rhombus.

__

The diagonals will have the same midpoint (bisect each other) if the sum of the coordinates at the ends of one diagonal is the same as the sum of the end point coordinates of the other diagonal:

  A +C = B +D

  (3, 6) +(9, 6) = (6, 8) +(6, 4)

  (3+9, 6 +6) = (6 +6, 8 +4)

  (12, 12) = (12, 12) . . . . . . midpoints are the same; ABCD is a parallelogram

__

The diagonals will be perpendicular if the sum of the products of the coordinate differences of their end points is zero.

  AC⋅BD = (C -A)⋅(D -B) = (9 -3, 6 -6)⋅(6 -6, 4 -8)

  = (6, 0)⋅(0, -4) . . . . . end point differences; we want their dot-product

  = (6)(0) +(0)(-4) = 0 +0 = 0 . . . . diagonals are perpendicular

_____

Additional comment

The midpoints are computed as (A+C)/2 and (B+D)/2. We have multiplied each of them by 2 to simplify the arithmetic. Our resulting sums of (12, 12) must be divided by 2 to get the actual midpoint of the rhombus: (6, 6).

The notion of "dot product" is a vector notion. Two vectors are perpendicular when their dot product is zero. The dot product is the scalar sum of the products of corresponding coordinates.

Answer:

Danil received 147 euros

Step-by-step explanation:

Let, Danil,Gabriel and Hardly share some money of 3x:5x:9x ratio then,

From the question,

9x - 5x= 196

or, 4x= 196

or, x = 196/4

or, x = 49 euros

Again,Danil received 3x share of money

=3*49

=147 euros

Answer:

Step-by-step explanation:

Ratio = 3 : 5 : 9

Money received by  Danil = 3x  

Money received by Gabriel = 5x

Money received by Hadley = 9x

Difference in the amount between Gabriel and Hadley = 196 euros

9x - 5x = 196

       4x = 196

         x = 196/4

        x = 49

Money received by Danil = 3*49

                                           = € 147

The volume of the cone and pyramid are the same.

Formula for volume of cone = ⅓(144π × h)

Volume of cone = ⅓[πr² × height of cone)

Volume of triangular pyramid = ⅓[(½bh × height of pyramid)]

Also note the following:

Area of a circle = πr²

Area of a triangle = ½bh

Part A:

Area of circle 1 = πr² = π(12²) = 144π units²

Area of circle 2 = πr² = π(6²) = 36π units²

Area of circle 3 = πr² = π(3²) = 9π units²

Area of triangle 1 = ½(24)(12π) = 144π units²

Area of triangle 2 = ½(12)(6π) = 36π units²

Area of triangle 3 = ½(6)(3π) = 9π units²

Part B: Based on our results in part A, the volumes of the cone and pyramid, having the same height are the same.

Part C:

Volume of pyramid = ⅓(144π × h)

Using this measurement and our conclusion in part B:

Formula for the Volume of a cone = ⅓(144π × h)

They are exempt from income tax and we would get the income tax withheld as $340.

The person does not have another source of income, and there are no exceptions that are claimed by the person.

The withheld tax which is held every week can be calculated as;

Amount of income tax = 30 % of 1,166

Amount of income tax = $339.6

Amount of income tax = $340

Hence, they are exempt from income tax and we would get the income tax withheld as $340.

The least amount of wrapping paper that Amy needs to wrap the present is 1936in².

Surface area is simply the amount of space covering the outside of a 3-dimensional object.

The surface area of a rectangular prism is expressed;

A = 2( wl + hl + hw )

Given the data in the question;

To determine the least amount of wrapping paper that Amy needs to wrap the present in the shape of a rectangular prism, we substitute our given values into the expression above.

A = 2( wl + hl + hw )

A = 2( (16in×20in) + (18in×20in) + (18in×16in) )

A = 2( 320in² + 360in² + 288in² )

A = 2( 968in² )

A = 1936in²

Therefore, the least amount of wrapping paper that Amy needs to wrap the present is 1936in².

The inequality of the expression is a greater than inequality, and the required inequality is 2x + y > 34

From the question, we have the following representations:

A field goal has 2 points, while a foul shot has 1 point.

So, the number of points in a game is:

Score = 2x + y

The team is behind by 34 points.

So, the team must attain above 34 points

This means that the score must be greater than 34.

So, the inequality is:

2x + y > 34

Step-by-step explanation:

Answer:

The answer is 20

Step-by-step explanation:

There's two ways in which you can do this. The first one, and the simpliest one is finding the derivative of the equation P(x). After finding the derivative, set the dy/dx to be zero (so set the derivative to be zero). Then solve for x. This should give you the point at which there's no increase or decrease in the value of P, thus meaning the point at which its the maximum.

The fair interval illustrates a sample space

The interval that will make a fair decision is from 5 to 20

From the question, we understand that:

Since they choose odd and even integers, then the sample space must be divisible by the number of people (i.e 2 people)

The sample space (S) is calculated as:

S = Highest - Least + 1

S = 10 - 2 + 1 = 9

S = 15 - 3 + 1 = 13

S = 20 - 5 + 1 = 16

S = 25 - 5 + 1 = 21

Only 16 can be divisible by 2

Hence, the interval that will make a fair decision is from 5 to 20
