PLEASE HELP!!!!! 3, 8, 13, 18, 23, ....<br><br> The recursive formula for this sequence is:
rodikova [14]

Answer:

a₈ = 37

Step-by-step explanation:

The given arithmetic sequence is: 3, 8, 13, 18, 23, . . .

The recursive formula for the sequence is: $ a_n = a_{n - 1} + 5 $

Here, $ a_n $ represents the $ n^{th} $ of the sequence.

And, $ a_{n - 1} $ represents the $ (n - 1)^{th} $ of the sequence.

'+5' denotes that '5' is added to the $ (n - 1)^{th} $ term to get the $ n^{th} $ term. In other words, the difference between two consecutive numbers in the sequence is 5.

Now, we are asked to find a₈ i.e., n =8.

Substituting in the recursive formula we get: a₈ = a₍₈₋ ₁₎ + 5 = a₇ + 5.

So, to determine a₈ we need to know a₇. From the sequence we see that a₅ = 23.

⇒ a₆ = 23 + 5 = 28.

⇒ a₇ = 28 + 5 = 32.

⇒ a₈ = 32 + 5 = 37.

Therefore, the $ 8^{th} $ term of the sequence is 37.

Month_1 Value = Month_0 Value * 0.95

Month_2 Value = Month_1 Value * 0.95 = Moth_0 Value * 0.95*0.95 = Month_0 Value * 0.95^2

Month _n Value = Month_0 Value * (0.95)^n

After 2 years ==> n = 24

Month_24 Value = Month_0 Value * (0.95)^24 = 2,000,000 *(0.95)^24 = 583,978.05

Petra fills a small cardboard box with sand. The dimensions of the box are 3 inches by 4 inches by 2 inches. What is the volume
mr Goodwill [35]

Answer: 24 in³

Step-by-step explanation:

You know that the dimensions of the box are:

3 inches.

4 inches.

2 inches.

As each face of the cardboard box is a rectangle, you can conclude that it has the form of a rectangular prism.

Therefore, to calculate the volume of the box, you must multiply the dimensions given in the problem.

Therefore, you obtain that the volume of the box is:

V=(3\ in)(4\ in)(2\ in)\\V=24\ in^3
