Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
Answer:
53
Step-by-step explanation:
6x3=18
8-3=5
6+1=7
7x5=35
35+18=53
I hope this helps!
Im pretty sure the correct answer is the fourth one
P= 4(348) because assuming the wear house has four sides that is the only logical answer
