− 1049
Espero te ayude :)
In the table, you can see level 1 is 5 to the first power, level 2 is 5 to the second and go on.
so in level 6 would be 5 to the sixth power
so the answer to first one is 5^6
for the second question you should know that level 2 is 5^2 and level 6 is 5^6 so 5^6/5^2 = 5^4 is the answer :))))
I hope this is helpful
have a nice day
Answer:
19.44 hours, about 19 hours 26 minutes
Step-by-step explanation:
The exponential equation that describes your caffeine level can be written as ...
c(t) = 120·(1 -0.12)^t . . . . where t is in hours and c(t) is in mg
We want to find t for c(t) = 10, so ...
10 = 120(0.88^t)
10/120 = 0.88^t . . . . . . . divide by 120
log(1/12) = t·log(0.88) . . . take logarithms
t = log(1/12)/log(0.88) ≈ 19.4386
It will take about 19.44 hours, or 19 hours 26 minutes, for the caffeine level in your system to decrease to 10 mg.
7.30×1.63=11.899
You only need 2 significant numbers because 7.30 only has 2, the 0 past the decimal without a number doesn't count.
The answer is 12
