Asample of an unknown chemical element naturally loses its mass over time. the relationship between the elapsed time t, in months, since the mass of the sample was initially measured, and its mass, m(t), is modeled by the following function: m(t)=120(81/625)t complete the following sentence about the rate of change in the mass of the sample. round your answer to two decimal places.
the mass of the sample decays by a factor of (3)/(5) every ? months

no one knows lol

step-by-step explanation:

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:

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
