Find the first four terms of a sequence using the recursive definition. Please help

Mathematics
1 answer:
Ymorist [56]4 years ago
7 0

Answer:

2, 5, 9, 19

Step-by-step explanation:

Using the recursive formula f(n) = 2f(n - 2) + f(n - 1)

with f(1) = 2 and f(2) = 5

f(3) = 2f(3 - 2) + f(3 - 1)

     = 2f(1) + f(2) = (2 × 2) + 5 = 4 + 5 = 9

f(4) = 2f(4 - 2) + f(4 - 1)

      = 2f(2) + f(3) = (2 × 5) + 9 = 10 + 9 = 19

Choose the number sentence that applies the commutative property to the example.
Vinil7 [7]

The number sentence that applies the commutative property to the example is 4 × 3 = 12

<h3>Commutative property</h3>

Commutative property can be additive or multiplicative. It is a way of changing the position of a function or value in an expression without affecting the result

Examples are

A +B = B +A

AB = BA

Although the value were interchanged, the result were not affected. Hence the number sentence that applies the commutative property to the example is 4 × 3 = 12 since changing 3 and 4 does not affect the result

3. This spinner is divided into eight equal-sized sections. Each section is labeled with a number
givi [52]

Answer:

Least Likely: Arrow lands on a section labeled with an odd number.

_____: Arrow lands on a section labeled with the number 1.

Most Likely: Arrow lands on a section labeled with a number less than 4.

Step-by-step explanation:

<u>The spinner:</u>

There are 8 sections, 4 labeled with the number 1, 2 labeled with the number 3, 1 labeled with the number 3, and 1 labeled with the number 4.

<u>Probabilities of the spinner:</u>

  • Probability of landing on 1: 4/8 - 50%
  • Probability of landing on 2: 1/8 - 12.5%
  • Probability of landing on 3: 2/8 - 25%
  • Probability of landing on 4: 1/8 - 12.5%

<u>The options:</u>

A - Arrow lands on a section labeled with an odd number.

B - Arrow lands on a section labeled with the number 1.

C - Arrow lands on a section labeled with a number less than 4.

  1. The least likely possibility out of the options would be B because, while a 50% chance sounds like a lot, it is the least of the three options.
  2. The mid possibility out of the options would be A. The odd numbers labeled on the spinner make up 75% of the whole. (1s and 3s - 50% + 25%)
  3. The most likely possibility out of the options is C because it accounts for every section except for the single section labeled with the number 4. (100% - 12.5%, 87.5%)
