There was a sample of 750 milligrams of a radioactive substance to start a study. Since then, the sample has decayed by 4.6% each year. Let t be the number of years since the start of the study. Let be the mass of the sample in milligrams.
Write an exponential function showing the relationship between and .

50.6

step-by-step explanation:

f(x) = y

f(-3) = -5

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:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
