Answer: HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

Step-by-step explanation:

Given: The coordinates of parallelogram H I J K as

H is at (- 2, 2), point I is at (4, 3), point J is at (4, - 2), and point K is at (- 2, - 3).

Diagonals : HJ and IK  [join opposite vertices]

Mid point of HJ = (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

=(\dfrac{-2+4}{2},\dfrac{2+(-2)}{2})=(1,0)

i.e. Mid point of HJ = (1,0)

Mid point of IK = (\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

=(\dfrac{4+(-2)}{2},\dfrac{3+(-3)}{2})=(1,0)

i.e. Mid point of IK = (1,0) =Mid point of HJ

<em>When mid points of both diagonals are equal then that means the diagonals bisect each other.</em>

<em />

Thus, HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

What is the arithmetic sequence in this problem . help plz
adell [148]

Answer:

<u>a(n)=80*(9/10)^(n-1)</u>

Step-by-step explanation:

I think u r confused

this sequence is geometric not arithmetic

HOw we know that ??

when we get a common difference  <u>that must Be equal  </u>

d=72-80=-8  not equal to  d=64.8-72=-7.2

So it is not arithmetic

but when we get the common ratio that also must <u>be equal </u>

r=72/80=9/10 equal to   r=64.8/72=9/10

So it is geometric

By using this equation:

a(n)=a*r^(n-1)

and we have <u>a=80 , r=9/10</u>

Then       <u>a(n)=80*(9/10)^(n-1)</u>

<em>I really hope this helps <3</em>
