Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 42 gram sample of a substance that's
used to treat thyroid disorders has a k-
value of 0.126.
Enter the correct answer.
-kt
N = Noe
DONE
No = initial mass (at time t = 0)
N = mass at time t
k= a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

the answer is ! ?
