Answer:

(4, 7)     (8, 9)    

(2, 3)     (6, 5)

Step-by-step explanation:

The definition of a parallelogram is a quadrilateral that has two pairs of opposite equal length parallel sides, including equal opposite angle measurements

To simplify the task, we plot the  points on a graph paper for the parallelogram ABCD to get the following points;

B (4, 7)     A (8, 9)    

C (2, 3)     D (6, 5)

The length of the opposite sides AB and CD are;

Length AB = √((9 - 7)² + (8 - 4)²) = √20 = 2·√5

Length CD = √((3 - 5)² + (2 - 6)²) = √20 = 2·√5

The length of the opposite sides AC and BD are;

Length AD = √((9 - 5)² + (8 - 6)²) = √20 = 2·√5

Length BC = √((7 - 3)² + (4 - 2)²) = √20 = 2·√5

The slope of segment AB is (9 - 7)/(8 - 4) = 2/4 =1/2

The slope of segment CD is (5 - 3)/(6 - 2) = 2/4 =1/2

Therefore, since the slopes of segments AB and CD are equal, segments AB and CD are parallel

Similarly, we have;

For segment AD, slope = (9 - 5)/8 - 6) = 4/2 = 2

For segment BC, slope = (7 - 3)/4 - 2) = 4/2 = 2

Therefore, the slopes of segments AD and BC are equal, segments AC and BD are parallel.

Answer:

y = 1

Step-by-step explanation:

The horizontal asymptote is the line, horizontally, where the graph doesn't cross. In this case, the graph approaches y = 1, but never touches 1, so your answer is y = 1.

Answer:

Option A.

Step-by-step explanation:

The given sequence is  

24, 30, 36, 42, 48, ...

It is an AP. Here,  

First term = 24

Common difference = 30-24 = 6

The given explicit formula for nth term is

[tex]a_n=a_1+(n-1)d[/tex]

where, [tex]a_1[/tex] is first term, d is common difference.

Substitute [tex]a_1=24, d=6 \text{ and }n=500[/tex] in the above formula.

[tex]a_{500}=24+(500-1)(6)[/tex]

[tex]a_{500}=24+(499)(6)[/tex]

[tex]a_{500}=24+2994[/tex]

[tex]a_{500}=3018[/tex]

The 500th term of the sequence is 3018.

Therefore, the correct option is A.

Answer: $735.49

Step-by-step explanation:

Given, the price of 10 tolas gold bought from American market = $553

Custom duty charge = 20%

VAT = 13%

Custom duty charge = 20% of $553

= 0.20 x 553  [we divide a perecntage to convet it into decimal]

= $110.6

VAT = 13% of $553

= 0.13 x 553

= $71.89

Selling price = Original price +Custom duty charge  + VAT

=  $553+$110.6+ $71.89

= $735.49

Hence, it should be sold at $735.49 .

The smallest number that is divisible by 1,2,3,4,5,6,7,8,9 and 10 is 2,520.

Step-by-step explanation:

2520/1 = 2520

2520/2 = 1260

2520/3 = 840

2520/4 = 630

2520/5 = 504

2520/6 = 420

2520/7 = 360

2520/8 = 315

2520/9 = 280

2520/10 = 252

Answer:

192

Step-by-step explanation:

y/12-5=11

y/12=11+5

y/12=16

y=16x12

y=192

Answer:

y = 192

Step-by-step explanation:

1st add 5 to both sides 12 to get 7: [tex]\frac{y}{11} =16[/tex]

then multiple both sides by 11 to isolate the y : [tex]y=192[/tex]

(11 times 16 equals 192)

Answer:

[tex]A(x) = 243[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^3 - 9x[/tex]

[tex]Interval: (12,6)[/tex]

Required

Determine the average rate of change

Average rate is calculated as thus;

[tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]

In this case; b = 12 and a = 6

Calculating f(12)

[tex]f(12) = 12^3 - 9 * 12[/tex]

[tex]f(12) = 1728 - 108[/tex]

[tex]f(12) = 1620[/tex]

Calculating f(6)

[tex]f(6) = 6^3 - 9 * 6[/tex]

[tex]f(6) = 216 - 54[/tex]

[tex]f(6) = 162[/tex]

Substitute 12 for b and 6 for a in [tex]A(x) = \frac{f(b) - f(a)}{b - a}[/tex]

[tex]A(x) = \frac{f(12) - f(6)}{12 - 6}[/tex]

Substitute values for f(6) and f(12)

[tex]A(x) = \frac{1620 - 162}{12 - 6}[/tex]

[tex]A(x) = \frac{1458}{ 6}[/tex]

[tex]A(x) = 243[/tex]

Answer:

[tex]\frac{12}{253}[/tex]

Step-by-step explanation:

So I would start by multiplying all the numbers on

the denominator first ----->

11 x 14 = 154

~~~

14 x 17 = 238

~~~                                    *BASICALLY: FIND THE COMMON DENOMINATOR*

17 x 20 = 340                        (this will be how u add everything at the end)

~~~

20 x 23 = 460

Now your goal is to get all of these numbers to be the same as the denominator so you can add them together at the end (get a common denominator)

**(remember when multipling the top and the bottom numbers, whatever you do to the bottom you must do to the top)**

   3                   3                    3                   3

--------- (x ?)  +  --------- (x ?)  +  --------- (x ?)  +  ---------  =

 154               238               340               460

Answer:

What are the coordinates of the resulting figure?

✔ (0, 0), (4, 0), (4, –4), (0, –2)

Step-by-step explanation:

its C on Edge

I just took this assignment and got it right

The coordinate of the given figure is, (0, 0), (4, 0), (4, –4), (0, –2).

We have to determine the coordinates of the resulting figure.

A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.it can be represented by (x,y)  that is the x-value and y-value.

Therefore the value of x and y at point (0,0) is 0 and 0.

The value of x and y at point (0,2) is 0 and 2.

The value of x and y at point (4,4) is 4 and 4.

The value of x and y at point (4,0) is 4 and 0.

Therefore the coordinate of the given figure is,

(0, 0), (4, 0), (4, –4), (0, –2)

Answer:

24 coins

Step-by-step explanation:

Start:

first pirate --> 1/2 coins

second pirate --> 3/2 coins

Next:

first pirate --> 1/2 + 3/4 = 5/4 coins

second pirate --> 3/2 - 3/4 = 3/4 coins

Next:

first pirate --> 5/4 - 5/8 = 5/8 coins

Answer:

0.00324 kilometres

Step-by-step explanation:

Remember:

100 centimeters = 1 meter

1000 meters = 1 kilometer

So first, let's add together the meters and centimeters. To do that, we have to convert the meters to centimeters. That would become 300 centimeters, then you add the 24 centimeters to get 324 centimeters. Then, you convert that to kilometers. You can use a calculator for this, but I'll show you how to do this without a calculator. Since 100 centimeters is one meter, and 1000 meters equals to one kilometer, there would be 5 spaces from 324 to our answer, so you move the invisible decimal point 5 spaces to the left, and you get your answer, which is 0.00324 kilometres!

Answer:

7/32

Step-by-step explanation:

Combinators. Your best friend in this scenario.

Basically, using combinations helps you to find the different ways that you could get heads three times out of eight. To do that, just get 8!/(3!5!) (this is a formula, not the exact numbers, per say, you should check that out), which ends up as 56. So there's 56 different ways that Peter can flip a coin eight times and land on heads three times.

Then, you divide that by the total number of possibilities, which in this case is 2^8, since every coin you flip gives you two different options, heads or tails.

Simplifying the fraction gets you 7/32.

Answer:

7/32

Step-by-step explanation:

the probability of getting exactly 3 heads when a coin is flipped 8 times in a row is: 7/32.
