You have a secret that you tell to one person. every hour, each of the people that know the secret tells one person. the number of people who know is n, and t is the number of hours since you told the first person. is n a linear function of t?

No, it is not a linear function. It is an exponential function.

Step-by-step explanation:

You have a secret that you tell to one person.

Every hour, each of the people that know the secret tells one person.

Let N be the people who know the secret.

Let t be the number of hours since you told the first person.

Now, when only you know the secret, means 1 person.

N(0) = 1

Next hour, there are now 2 people that know the secret.  

N(1) = 2

After the next hour, these 2 people will tell 2 more people, so people doubled to 4.

N(2) = 4

One hour later it will be N(3) = 8

We can see the pattern as following.

Therefore, the function is exponential not linear.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

it would open into a square depending on the type of envelope i’m not sure about the second part
