Organisms A and B start out with the same population size. Organism A’s population doubles every day. After five days, the popul

Alinara [238K]

Answer:

1. 252N = ( $2^{2}$ x $3^{2}$ x $7^{1}$ )N

2. Factor = $2^{5}$

Step-by-step explanation:

Let the starting population size for organisms A and B be represented by N.

For organism A;

Day 0: N

Day 1: 2N

Day 2: $2^{2}$ N

Day 3: $2^{3}$ N

Day 4: $2^{4}$ N

Day 5: $2^{5}$ N

Day 6: $2^{4}$ N

Day 7: $2^{3}$ N

Day 8: $2^{2}$ N

For organism B;

Day 0: N

Day 1: 2N

Day 2: $2^{2}$ N

Day 3: $2^{3}$ N

Day 4: $2^{4}$ N

Day 5: $2^{5}$ N

Day 6: $2^{6}$ N

Day 7: $2^{7}$ N

Day 8: $2^{8}$ N

1. After the eight days, organism B's population is larger than organism A's population by;

$2^{8}$ N - $2^{2}$ N = 256N - 4N

= 252N

= ( $2^{2}$ x $3^{2}$ x $7^{1}$ )N

2. Organism A's population grows by $2^{5}$ .

How do you find the domain and range of a function?

kati45 [8]

Domain is the input and/or x
Range is the output and/or y
So to find the domain you would look for the x axis in a graphed function, the input on a table, or the numbers in a problem that would be on that axis or side of the table. Same for range

Given the sequence 8, 16, 32, 64, ..., which expression would give the thirteenth term?

mrs_skeptik [129]

8, 16, 32, 64,…
×2 ×2 ×2

$a_{n} = a_{1} * r^{n - 1}$
$a_{n} = 8 * 2^{13 - 1}$
$a_{n} = 8 * 2^{12}$
$a_{n} = 8 * 4096$
$a_{n} = 32768$

   First Term: 8
      Second Term: 16
      Third Term: 32
      Fourth Term: 64
       Fifth Term: 128
      Sixth Term: 256
   Seventh Term: 512
   Eighth Term: 1024
   Ninth Term: 2048
      Tenth Term: 4096
   Eleventh Term: 8192
   Twelfth Term: 16384
Thirteenth Term: 32768

$The\ expression\ that\ would\ give\ the\ thirteenth\ term\ of\ the\ problem\ would\ be\ the\ equation\ of\ the\ geometric\ sequence,\ which\ is\ equal\ to\ a_{n} = a_{1} * r^{n - 1}.$
