Answer:
t = 6.3
Step-by-step explanation:
N=Noe^(-kt)
No = 14 grams
k = .1092
We want to find t when N = 7 or 1/2 of 14
N=Noe^(-kt)
7 = 14 e ^ (-.1092t)
Divide each side by 14
1/2 = e ^ (-.1092t)
take the natural log of each side
ln (1/2) = ln e ^ (-.1092t)
ln (1/2) = -.1092t
Divide each side by -.1092
ln (1/2)/ -.1092 = t
t≈6.3475
Rounding to the nearest tenth
t = 6.3
Answer: About 91.54 times.

Answer:
1. 6
2. 23
Step-by-step explanation:
1.
logx+1 ( x^2 + 2x + 1)^3
= 3logx+1 ( x^2 + 2x + 1)
= 3 logx+1 (x + 1)^2
= 6 logx+1 (x + 1) Now the logx+1 x+1 = 1 so
The answer is 6.
2.
log11 11^23
= 23 log11 11
As in question 1 log11 11 = 1
So the answer is 23.
