Answer:
Amount she Receive in 5 years = $3506.37
Step-by-step explanation:
Given in question as
Ebonie invests amount in account = P = $2500
The interest rate she will have = 7%
The amount will keep in account for 5 years
Now we apply compound interest (CI ) to determine how much she will receive after 5 years ,
So , for CI
Amount = principal ( 1 + ^ T ,where T is Time
So, A = 2500 ( 1 +)^5
Or, A = 2500 (1.40255)
Or, A = $3506.37
Hence Amount she will receive $ 3506.37 Answer
Answer:
It would take 24 minutes for the element to decay to 50 grams
Step-by-step explanation:
The equation for the amount of the element present, after t minutes, is:
In which Q(X) decays radioactively with a half life of 12 minutes.(0) is the initial amount and r is the rate it decreases.
Half life of 12 minutes
This means that
So
If there are 200 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 50 grams?
This is t when Q(t) = 50. Q(0) = 200.
It would take 24 minutes for the element to decay to 50 grams
