Answer:
There will be 916 ants alive after 4 months.
Step-by-step explanation:
Step 1
Let's change the percentage to a decimal by dividing by a 100.
6.5% / 100 = .065
Step 2
So, for the first month we will multiply the initial amount of ants by .065 and this will give us the number of ants that die.
1200 * .065 = 78
This means that after the first month, 1200 - 78 = 1122 ants will be alive.
Step 3
Now for the second month: 1122 * .065 = 72.93 (rounded to 73)
1122 - 73 = 1049 ants will be alive
Step 4
For the third month 1049 * .065 = 68.185 (rounded to 68)
1049 - 68 = 981 ants will be alive
Step 5
For the fourth month 981 * .065 = 63.765 (rounded to 64)
981 - 64 = 916 ants will be alive
Hope this helps!
Answer: 59.02 inches.

Answer:
$1271.25
Step-by-step explanation:
Since it's continuously compounded, the 2nd formula is most appropriate.
A=Pe^rt
P = initial investment = $1000
r = rate of increase = 8% = 0.08
t = time interval in years = 3
If you put in hlthe information you should have:
A = 1000•e^(0.08)(3) = $1271.25
