A teacher writes a simple computer program where she can type students name and computer tells her the students birthday.
Vikki [24]

Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.

<h3>When does a relation represent a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

For this problem, we have that:

  • The input is the student's name.
  • The output is the student's birthday.

Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.

vivado [14]

Answer:

"$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

So, c = $98

Total payment = amount financed + c  = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

                                      =798 ÷ 12

                                      =$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!
