An arithmetic sequence is a sequence in which the difference between each consecutive term remains same (constant).
The explicit formula for an arithmetic sequence is , where a is first term of sequence, d is the common difference between consecutive terms.
A) We can see from Julio's swimming distance that it is in arithmetic sequence as after every successive training session Julio's swimming distance increased by 0.30 miles.
Therefore, we can see that Julio's training schedule is an arithmetic sequence.
B) Let us find Julio will take how many days to swim 2.95 miles by using explicit formula.
Let us substitute our given information in above formula.
We are told that Julio swims every two days, this implies that he would swim on alternate days. So he will swim 2.95 miles on 10*2 =20th day.
Let us find 20th day will be which day. As Julio started his training schedule on Tuesday, 20th day will be a Sunday. Therefore, Julio will swim for 2.95 miles on a Sunday.
Answer:
Step-by-step explanation:
The surface area of a rectangular prism can be calculated with the following formula:
Where "l" is the length of the rectangular prism, "w" is the width and "h" is the height.
In this case you can say that the length, the width and the heigth of this rectangular prism, are the following:
Knowing these values, you can substitute them into the formula shown before:
Finally, you must evaluate in order to calculate the surface area of the rectangular prism.
You get that this is:
