Help ASAP ! Find PN triangle proportionality

BaLLatris [955]

This has to do with ratio's.

MQ : QN = 2 : 5
MQ : QN = LP : PN
2 : 5 = 3 : PN

That means PN = 15/2

IN NEED OF A MATH WIZ!!!!!

densk [106]

The unoccupied volume will be the volume of the can minus the volume of the three tennis balls.

V=HπR^2-3(4πr^3)/3

V=HπR^2-4πr^3 where H=height of can, R=radius of can, r=radius of ball

We are told H=7, R=1.5, and r=1.125 (2.25/2=d/2=r) so

V=7π1.5^2-4π1.125^3

V=15.75π-5.6953125π in^3

V≈31.58 in^3

Enter a recursive rule for the geometric sequence. 6, −18, 54, −162, ...

svlad2 [7]

Answer:

The required recursive formula is:

$a_n=(-3)\times a_{n-1}$

Step-by-step explanation:

We are given a geometric sequence as:

6,-18,54,-162,.....

Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.

Let $a_n$ represents the nth term of the sequence.
