im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625
<span>Exponential decay are; the domain is all real numbers, the base must be less than 1 and greater than 0 and the function has a constant multiplicative rate of change. The answers are letters A, D and E. An example is w</span>hen there are 70000 bacteria
present in a culture and reduced by half every four hours, the number of
bacteria will decrease. The bacteria will experience an exponential decay
because it decreases its number at a constant decay.
