Answer:
B. 8.66%
Step-by-step explanation:
In this case we have to evaluate the following formula:
n = e ^ (k * t)
where n would be the growth rate, we are told that it doubles therefore it is 2.
k is the monthly rate and time, 8 months.
Solved for k, we are left with:
ln (n) = k * t
k = ln (n) / t
replacing we have:
k = ln (2) / t = 0.693 / 8
k = 0.0866
If we take this to a percentage it would be 0.0866 * 100 = 8.66%
Therefore the answer is B.
Answer:
c) x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)?
=15x-10=10+6+2x
=15x-2x=10+6+10
=13x=26
=13x/13=26/13
=therefore X=2
