d. both a relation and a function:

Given:

Mark records his science scores in each monthly assessment over a period of 5 months. In the first assessment he scores 76%. In the second assessment he scores 73%. After that, his scores keep increasing by 2% in every assessment.

x represents the number of assessments since he starts recording and y represents the scores in each assessment.

In order for a relation to be a function the association has to be unambiguous that means that for a given input only one output can exist.If an input can have two or more outputs then you cannot determine which is the correct output for that input.

In the given situation:

x is the input that is number of assessments since mark starts recording the scores so there is only one assessment no repeating.so there is only one output.

Hence the relation is a function.

Rita earns $16.00 per hour. If she gets a 3% raise, what will be her new hourly wage?
Vikentia [17]
All percentages can be expressed as fractions or decimals. To find a percentage of a number, we multiply the percentage with the number. In this case:
3/100 * 16/1 = 48/100 = 0.48
Or:
0.03 * 16 = 0.48
Her new hourly wage would be $16.48

Different types of parallelograms have distinguishing traits. Compare and contrast the rectangle, rhombus, and square based upon
Stels [109]
All 3 of the listed parallelograms have both pairs of sides parallel, by definition.

The square and the rhombus have all congruent sides.

Since the square and rhombus have all 4 congruent sides, this means their opposite sides are congruent.  Additionally, rectangles have opposite sides congruent.
