Mary deposits $550 in a savings account at 3% simple annual interest. The value of this account, v, is given by the function v = 550 + 16.5t, in which t is the number of years the money is in the bank. What is the domain & range of this function?

and .

Step-by-step explanation:

It is given that, the value of this account, v, is given by the function

where, t is the number of years the money is in the bank.

We need to find the domain & range of this function.

Domain is the set of input values. Here, the domain is number of years which cannot be negative. So,

Range is the set of output values. Here, the range is amount after simple interest which cannot be less than the principal value.

answer: f = 32.2m

step-by-step explanation: that is the answer

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.
