Answer:
B: Exponential decay
Step-by-step explanation:
At the rate of 5% per hour, time to take another 100 to get infected is essentially time to double the infection.
We can use the rule of 72 to get a quick rough estimate
time = 72/5=14.4 hours.
Exact value:
100(1.05)^t = 200
1.05^t=2
take log
t=log(2)/log(1.05)
= 14.21 hours
Answer:
not sure for the 1st one but pretty sure 2nd one is B
Step-by-step explanation:
Sets b,c, and d are positive because they keep going up. The set a is the negative set
b, c, or d is correct because e > 4.8
explanation:
9+10e>57
you have to first leave 10e alone, so you take the opposite sign of the term that is on the same side as the variable and coefficient
57-9=48
so, the inequality will simplify to 10e>48
now all you have to do is isolate the variable e!
for that, simply divide 10 on both sides, one side will cancel out, the other side will come up with the quotient of 4.8
in conclusion, e>4.8
