The first five terms of the recursively defined sequence are 6, 12, 48, 768, 196608

For given question,

We have been given the recursive formula of a sequence.

a_{k+1}=\frac{1}{3}{a_k}^2

Also, the first term of the sequence is,

a1 = 6

Substitute k = 1 in given recursive formula.

⇒ a_{1+1}=\frac{1}{3}{a_1}^2

⇒ a2 = 1/3 (6)²

⇒ a2 = (1/3) × 36

⇒ a2 = 12

Substitute k = 2 in given recursive formula.

⇒ a_{2+1}=\frac{1}{3}{a_2}^2

⇒ a3 = (1/3) × (12)²

⇒ a3 = (1/3) × 144

⇒ a3 = 48

Substitute k = 3 in given recursive formula.

⇒ a_{3+1}=\frac{1}{3}{a_3}^2

⇒ a4 = (1/3) × (48)²

⇒ a4 = (1/3) × 2304

⇒ a4 = 768

Substitute k = 4 in given recursive formula.

⇒ a_{4+1}=\frac{1}{3}{a_4}^2

⇒ a5 = (1/3) × (768)²

⇒ a5 = (1/3) × 589824

⇒ a5 = 196608

Therefore, the first five terms of the recursively defined sequence are 6, 12, 48, 768, 196608

The correct unscrambling of whyrot is worthy.

<h3>What is unscrambling?</h3>
  • A word unscrambler is essentially a gadget that you feed all the letters into and it rearranges them to reveal all potential word combinations.
  • Some might be concerned that this is a cheating method. However, if everyone playing the game has the option of using a word unscrambler, then the playing field is unquestionably even.
  • A player may opt not to use the word generator and instead come up with their own list of terms. Having said that, they might want to utilize it afterward to assess their performance and review the entire list of terms they could have used.

Lemur [1.5K]
1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5

2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4

probability both balls are blue : 3/5 * 1/4 = 3/20 <==

RSB [31]

Answer:

a) 22 batches

c) 7.3 batches

Step-by-step explanation:

a) It takes 0.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.50 cups of sugar. How many batches of cookies can I make?

0.25 cup = 1 batch

5.5 cup = x

Cross Multiply

0.25 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.25 cup

x = 22

I can make 22 batches of chocolate chip cookies. You may use the scratchpad to show your work.

(b) Lemon Cookies It takes 0.75 cups of sugar to make a batch of lemon cookies. I have 5.5 cups of sugar. How many batches can I make?

0.75 cup = 1 batch

5.5 cup = x

Cross Multiply

0.75 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.75 cup

x = 7.3 batches

I can make 7.3 batches of lemon cookies. You may use the scratchpad to show your work.
