Answer:

number 1 is c      number 2 is b,c,e  number 3 is b

Step-by-step explanation:

1: if you see something to the power you will always think of repeated multiplication off the bat. so you just multiply the coefficient by the amount of the exponent.

2: 1*1*1*1*1*1*1*1*1*1*1*1*1*1*1*1=1 no

2*2*2*2=16 yes

4*4=16 yes

8*8=64 no

16=16 yes

3: 3/4*3/4*3/4=27/64

hope this helps! have a nice day!

Need help with problem #53! Arithmetic sequences!
ankoles [38]

When counting any sequence, it helps to have a simpler sequence to compare it to. The simplest one that I can think of is

1,2,3,4,5,\dots

because you instantly can tell the number of terms in the sequence by looking at the last number. We can see from the graph that the first few terms of the sequence a are 1, -3, -7, and we're told that its last term is -83. Our goal then is to turn this sequence:

1,-3,-7,\dots,-83

into this one:

1,2,3,\dots

The first thing which stands out in this sequence is the number of negative terms, so let's fix that by multiplying every term by -1:

1,-3,-7,\dots,-83\xrightarrow{\times{-1}}-1,3,7,\dots,83

Now, the main property of any arithmetic sequence is that they <em>increase or decrease by some constant amount</em>. Here, that number is 4, since -3 = 1 - 4 and -7 = -3 - 4. Knowing the importance of 4 in this sequence, our next step might be to turn every term into a multiple of 4 by adding 1:

-1,3,7,\dots,83\xrightarrow{+1}0,4,8,\dots,84

and since we're dealing with multiples of 4, a natural next step might be to divide every term by 4:

0,4,8,\dots,84\xrightarrow{\div4}0,1,2,\dots,21

And lastly, we can add 1 to every term to get our sequence into easily-countable form:

0,1,2,\dots,21\xrightarrow{+1}1,2,3,\dots,22

So, the sequence a has 22 terms.

She has 65 water bottles....and she is buying boxes of water bottles (x) that hold 16 water bottles each. She can only buy up to 5 water bottles.

f(x) = 16x + 65...where f(x) = total water bottles and x = number of boxes
x < = 5.....here is ur restriction

the range is ur f(x) values which represent the total number of water bottles...keep in mind, she can only buy 5. Therefore, the numbers that can be subbing in for x are 0 thru 5.

So when subbing in 0 thru 5 for x, the results for f(x) are :
{ 65,81,97,113,129 } <== ur range
