638272 is the radius I think
Answer:
Step-by-step explanation:
So a geometric sequence can be explicitly defined as: 
. IN this case we're given r, but we don't know what a_1 is. We can find this by lugging in 4 as n, and -8 as a_n, since they're given values
Plug known values in:
Subtract the values in the exponent
Simplify the exponent
Divide both sides by -8
So the nth term can be defined as: 
, and since the 1 is redundant, the equation can simply be defined as:
Answer:
y=0.5x-2
Step-by-step explanation:
8y=4x-32/2
First thing you are going to do is solve for 32/2=16 and then enter it into the equation.
8y=4x-16
Second thing you are going to do is divide everything by 8 to get rid of 8y.
8y=4x-16
-------------
8
4/8=0.5 and 16/8=2
y=0.5x-2
