"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409. The greatest possible value of that fraction is. (239)/(409 squared) .

The population of a rabbit colony triples every 3 days. The population starts at 10 rabbits. Write an exponential function that

qaws [65]

Answer:

Step-by-step explanation:

The population at various days is as follows since population triples every 3 days

<u>Day</u> <u>Population</u>

0 10

3 30

6 90

9 270

.... ......

This can be modeled by the general equation

$n_{t} = n_{0}(r)^{t/k}$

where

$n_{t}$ is the population after t days

$n_{0}$ is the population at start (10)

$r$ is the rate at which population changes ie 3

$t$ is the number days from start

$k$ is the number of days at which the population triples(here k =3 days)

We can check this by plugging in values for each of the variables

At day 0, population = 10(3)⁰ = 10. 1 = 10

Similarly populations for days 3, 6, 9 are:

$\\\\10.3^{3/3} = 10. 3^1 = 10.3 = 30\\10.3^{6/3} = 10. 3^2 = 10.9 = 90\\\\10.3^{9/3} = 10. 3^3 = 10.27 = 270$

Caitlin is at the grocery store, and she’s trying to finthe unit price on a 6-pack of drinks on sale for $2.99.

Ilia_Sergeevich [38]

Well, first off, any ameteur who read the question once would know he is INCORRECT, this is because you can easily see he's dividing it by 3 not 6 like you should be, so 2.99 divided by 6 is 0.498333 ( continuing ) so since this must be rounded to the nearest hundredth, so, 50 cents per bottle.

So question 1: No, because he divided with the incorrect numbers.

Question 2:( I actually don't understand this question, cause we just established he was wrong ) so since I don't understand this one, imma say no, or meh.

CORRECT unit rate: 50 cents per bottle.

Hope this helps, if not, comment below please!!!!
