holly begins with one penny in her piggy bank. she adds two pennies on day 1, four pennies on day 2, and eight pennies on day 3. she continues this pattern for 30 days.

which statement describes why this sequence is a function?

select each correct answer.
a the graph of this sequence would pass the horizontal line test.
b the graph of this sequence would pass the vertical line test.
c each day corresponds to a unique amount of pennies in this sequence.
d each amount of pennies corresponds to a unique day in this sequence.

option:C is correct.

Step-by-step explanation:

we could clearly see that the graph of this system will pass through the points i.e. the points (1,2),(2,4),(3,8),......(30,2^30).

so based on the observation from the graph we see that each each day corresponds to a unique amount of pennies in this sequence as there is always a different value of 2^x for each x=1,2,...30.

Hence, option C is correct.

4

step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
