Answer:
I believe the answer is B
Step-by-step explanation:
Answer:
It will take approximately 3.34 hours for the drug to decay to 90% of the original dosage
Step-by-step explanation:
As suggested, we use the formula for exponential decay:

From the given information, the half life of the drug in blood id 22 hours, so that means that it takes that number of hours to go from the initial value
, to a final value equal to
. Using this information we can find the decay rate "k" by solving for this parameter in the formula, and using the natural log function to bring the exponent down:

Now we use this value for the decay rate "k" to calculate how long it would take to decay to 90% of the original dose;

The answer is A. Martha has a shorter distance left to get to the aunt’s house than Jackson since 2/3 is .667 or 67%. Therefore this statement is false
Answer:
5/13
Step-by-step explanation:
sin R = opp side/ hypotenuse
sin R = 5/13
It would be D hope this helps
