Proof with explanation:
We know that the sum of first 'n' terms of a Geometric progression is given by
where
a = first term of G.P
r is the common ratio
'n' is the number of terms
Thus the sum of 'n' terms is
Now the sum of first '2n' terms is
Now the sum of terms from 
to 
term is 
Thus the ratio becomes
Answer: x = 15; y = 32; z = 2.5
see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.
=> this parallelogram is a square
=> the diagonal lines of the parallelogram are perpendicular to each other
=> m∠1 = 90°
⇔ 3y - 6 = 90
⇔ 3y = 96
⇔ y = 32
because this is a square
=> 3x = 18z = 45°
=> x = 15
z = 2.5
Step-by-step explanation:
Answer:
-2.0659021
Step-by-step explanation:
If the number you're dividing by has a decimal, move the decimal point all the way to the right counting the number of places you've ... In this problem we divide 4.71 by 3.2 out to 3 decimal places in the quotient answer.
Hope this helps
