Answer:
(a) It is a function.
(b) D = [1,2,3,4,5]
(c) R = [40,80,120,160,200]
Step-by-step explanation:
(a) Is this a function?
Yes, in order to be a function we need two groups, in this case "time in days" and "total cost". From this group the first one is called the domain, while the other one is called range. The elements in the domain can only have one associated element in the range. By this definition the graph displays a function.
(b) What is the domain?
The domain of a function are the numbers which represent the possible input. In this case it is the group of integer numbers from 1 to 5, in order words D = [1, 2, 3, 4, 5].
c) What is the range?
The range is the group which represent the output of the function and in this case it is the group R = [40, 80, 120, 160, 200]
Answer:
speed conversion. feet into inches and minutes into seconds.
120 inches/sec
Step-by-step explanation:
600 ft / min
youd multiply feet into inches and minutes into seconds
so since 12 inches are in a foot it would be 600 feet x 12 inches
and there are 60 seconds in a minute so 1 minute x 60 seconds
600 x 12 = 7200
1 x 60 = 60
now you divide 60 into 7200
7200 inches / 60 seconds = 120 inches per second
120 inches / second
