Use the compound interest formula: A=P(1+i)^t.
P is the initial amount of the drug, 0.3ml.
i is - 0.0035.
t is in seconds.
You'll get:
A=0.3(1-0.0035)^t.
Sub in any value on t to find out how many ml are left t seconds after injection.
The 0.65 second injection time does not seem to be relevant as the question clearly states that the exponential decay starts AFTER the injection is completed.
The third one its already in order
939/10,000 the decimal place indicates the fraction. You would love the decimal over 4 spaces which is the ten thousands place so that is what you set 939 over!
Answer:
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19
I would appreciate if my answer is chosen as a brainliest answer
