Consider the sequence: <br><br> 3, 8, 13, 18, 23, ...
suter [353]

Answer:

a_n represents a particular any term and a_{n-1} represents just previous term.

a_8=38

Step-by-step explanation:

In the given recursive formula,

a_n= a_{n-1}+5

a_n represents n^{th} \ term

and a_{n-1}represents just its previous term.

To find a_8, first five terms are given there. We need to find its previous terms a_6 \ and\ a_7

a_6 = a_{n-1}+5\\a_6= a_{6-1}+5\\a_6 = a_5 +5\\substitute \ a_5 =23\\a_6 = 23+5=28

Similarly,

a_7 = a_{n-1}+5\\a_7= a_{7-1}+5\\a_7 = a_6 +5\\substitute \ a_6 =28\\a_7 = 28+5=33

Similarly,

a_8 = a_{8-1}+5\\a_8= a_{8-1}+5\\a_8 = a_7 +5\\substitute \ a_7 =33\\a_8 = 33+5=38

Thus a_8 = 38 is the answer.

A colony of 900,000 bacteria doubles
shusha [124]

255 hours / 85 hours = 3.

This means that the bacteria will double in size 3 times.

900,000 × 2 = 1,800,000

1,800,000 × 2 = 3,600,000

3,600,000 × 2 = 7,200,000

After 255 hours, the colony of bacteria will be 7,200,000

Find the domain and range of the relation. Also determine whether the relation is a function.
OLEGan [10]

Answer:

The relation is a function!

Your Domain should be...

{-1, 1, 7, 9}

Your Range should be...

{-1, 8, 9}

WHY?

Your domain is always your x-coordinates, which are the first coordinates in a pair.

Your range is always your y-coordinates, which are the second coordinates in a pair.

When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.

Also, when listing points for your range, remember, if they repeat, you should only count one of the numbers, as you can see from the answer, there was two nines, but instead I put one.
