Every day, there are 3 times more likes on an internet video of a cat which is modeled by the function c(n) = (3)n − 1, where n is the number of days since the video posted. on the first day, there were 143 likes. what is the function that shows the number of likes each day?

The options are:

A.

B.  

C. c(n) = (3)143 − n

D.

SInce, The video of a cat is modeled by the function

Let us consider the A option.

When n =1

which is not equal to 143.

Hence, it is not the required function.

Let us consider the option B,

When n=1

c(1) =   = 0, which is not equal to 143.

Hence, it is not the required function.

Let us consider the C option

c(n) = (3)143 − n

When n=1,

c(1) = (3)143 − 1

= 428, which is not equal to 143.

Hence, it is not the required function.

Let us consider the D option

When n=1

c(1) =

= 143

Hence, it is the required function.

Therefore, Option D is the correct answer.

idk sry

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
