Scarlett bought an ant farm with 80 ants. from the following week forward, the ant population tripled every week. let a(n) be the number of the ants in scarlett’s farm in the nth week since she got it.

is this arithmetic or geometric sequence!
a(n)=
how mann ants after 8 weeks?

524880

Step-by-step explanation:

Scarlett bought an ant farm with 80 ants. From the following week forward, the ant population tripled every week.

So, the population of ant after 1st week will be (80 × 3) = 240

Again, after 2 weeks this will be (240 × 3) = 720

Therefore, the ant population is increasing in a geometric sequence and here the first term is 80 and the common ratio is 3.

Hence, if a(n) is the population of ant after n weeks then,  

 (Answer)

Now, there will be ants after 8 weeks. (Answer)

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
