Quadrilateral ABCD?<br>​
Mashutka [201]

The given quadrilateral is a kite.

Given: Point A (2, 4), B (-2, -5), C (7, -1) and D (7, 4)

Firstly, we find the distance between AD and DC

AD = \sqrt{(7 - 2)^{2} + (4 - 4)^{2}  }

⇒ AD = \sqrt{5^{2} }

⇒ AD = 5

DC = \sqrt{(7 - 7)^{2} + (4 - (-1))^{2} }

⇒ DC = \sqrt{5^{2} }

⇒ DC = 5

Hence, AD = DC = 5

Now, find the distance between AB and BC

AB = \sqrt{(-2 - 2)^{2}  + (-5 - 4)^{2} }

⇒ AB = \sqrt{(-4)^{2} + (-9)^{2}  }

⇒ AB = \sqrt{16 + 81}

⇒ AB = \sqrt{97}

BC = \sqrt{(7 - (-2))^{2} + (-1 - (-5))^{2}  }

⇒ BC = \sqrt{9^{2}  + 4^{2} }

⇒ BC = \sqrt{81 + 16}

⇒ BC = \sqrt{97}

Hence, AB = BC = √97

In the given quadrilateral, the two pair is of equal length and these sides are adjacent to each other.

Hence, it follows the property of kite.

Suppose $600 is compounded yearly for 20 years. If no other deposits are made, what rate is needed for the balance to triple in
denis-greek [22]

Answer:

5.65%

Step-by-step explanation:

Principal=$600

Time=20 years

FV=600*3=$1800

n=1

r=?

r= n[(A/P)^1/nt - 1]

=1{(1800/600)^ 1/1*20 - 1}

={(3)^1/20-1}

=3^0.05-1

=1.0565-1

=0.0565

rate=0.0565*100

=5.65% to the nearest hundredth percent

oksano4ka [1.4K]

Answer:

the most basic case, three-dimensional model can be created from simple shapes like cubes, rectangles, and triangles. These shapes are then modified into complex, high-polygon designs.At the same time, the geometric model provides essential information to the system model, including critical sizing and tolerances, other physical properties, and mechanical interconnection.

Step-by-step explanation:

Michael is cutting a 100-yard ribbon into pieces 3.4 yards long. He says that an inequality that represents his project is 3.4x
bogdanovich [222]

Answer:

3.4x\le 100

Step-by-step explanation:

Given that,

Michael is cutting a 100-yard ribbon into pieces 3.4 yards long.

Michael says that an inequality that represents his project is 3.4x 100.

Let Michael cuts the ribbon in x no of variables. It is given as :

3.4x is the total length of all the pieces together

i.e.

3.4x is less than or equal to 100.

The required equation that represents the given scanario is :

3.4x\le 100

Mr. Tanaka is 35 years old, and his son is 5.  In how many years will Mr. Tanaka be exactly three times as old as his son?( show
Kisachek [45]

Answer:

10 years.

Step-by-step explanation:

Present age of Mr. Tanaka = 35 years

Present age of his son = 5 years

Now let the number of years be x. As after x years both of their age will increased by x years, therefore

After x years age of Mr. Tanaka = 35 + x

After x years age of his son = 5 + x

According to question,

Mr.Tanaka's age after x years = 3 (His son's age after x years)

35 + x = 3 (5 + x)

Further solving,

35 + x = 15 + 3x

3x - x = 35 - 15

2x = 20

x = 10

Therefore after 10 years Mr. Tanaka's age will be exactly three times as old as his son. As after 10 years Mr. tanaka's age will be 45 and his son's age will be 15.
