35 + 3n= x 
x being the total amount of stamps!

is there a substitution for n? or a number of months?

Answer:

a_n = 3n + 32

Step-by-step explanation:

Ava purchased a set of 35 stamps. Each month, starting the second month, she purchased 3 more stamps for her collection.

So first month she has 35 stamps, second months she has 38 stamps and so on...

35, 38, 41, 44........

This is arithmetic sequence , so we use formula

a_n = a_1+(n-1)d

Where a1 is the first term and d is the difference

a1= 35, d= 3

so formula becomes

a_n = 35+(n-1)3

a_n = 35+3n - 3

a_n = 3n + 32

What is a polynomial function in standard form with zeroes 1, 2, -2. and -3
Juli2301 [7.4K]
<span>A polynomial with the given zeros can be represented as
   f(x) = (x-1)(x-2)(x+2)(x+3).
   Note that if you set f(x) = 0, then 1,2,-2, and -3 certainly are the solutions. From here, we simply multiply/expand out the polynomial. We can do this in a variety of ways, one of which is taking the left two and right two products separately. We have
   (x-1)(x-2) = x^2 - 3x + 2
   and
   (x+2)(x+3) = x^2 + 5x + 6.
   This gives that
   f(x) = (x^2 - 3x + 2) (x^2 + 5x + 6).
   Expanding this expression out then gives us our answer as
    f(x) = x^4 + 2x^3 - 7x^2 - 8x + 12
   or answer choice B.</span>

Step-by-step explanation:

Because the two triangles are similar:

\dfrac{x}{9}=\dfrac{16}{x} \\\\\\\dfrac{x^2}{9}=16 \\\\\\x^2=144 \\\\\\x=12

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
zalisa [80]

Answer: 272

Step-by-step explanation:

Let a1=11

a2=20

a3=29

Formula for sequence=

an=a1+(n-1)d

an = nth term

a1= first term

n= nth position

d= common difference

We are looking for the 30th term,so our n=30

d= a2-a1

d= 20-11

d= 9

Using the formula

an= a1+(n-1)d

a30= 11+(30-1)9

a30= 11+(29)9

a30= 11+(29×9)

a30= 11+261

a30= 272

Therefore, the 30th term is 272
