Answer:
Step-by-step explanation:
We are given:
And we want to find:
This is equivalent to:
So, we will evaluate g(-5) first, which yields:
So:
Then:
Therefore:
Answer:
$300
Step-by-step explanation:
In this question, we are simply asked to calculate the simple interest on $3000, at a rate of 20% paid after 6 months.
We can do this as follows. Mathematically, it should be remembered that:
S.I = PRT/100
In this case, we lost out the individual values as follows:
P = $3000, R = 20% and T = 6 months = 0.5years, S.I = ?
We substitute the parameters into the equation:
S.I = (3000 * 20 * 0.5)/100 = $300
11/16..." / " means divide....= 0.6875
0.688
when comparing, if it makes it easier, line ur decimals up and put a zero in any empty spaces...
0.6875
0.6880 (this is the same as 0.688)
so the one that is bigger is : 0.688 <==
Answer:
(i) Approximately 3 half lifes
(ii) 
Step-by-step explanation:
(i) ∵ The half life of Radon-222 is approximately 3.8 days,
So, the number of half life in 11.46 days = 
≈ 3
(ii) Since, the half life formula is,
Where,
= initial quantity,
t = number of periods
= half life of the quantity,
Given,
N = 
t = 11.46 days,
C=2π√150 ft
Or, C≈76.95 ft
Comment if you want to see how I did this.
