Consider the sequence:

Mathematics
2 answers:
Alekssandra [29.7K]3 years ago

Explicit definition of the given sequence is: aₙ=2n+3

Option A is correct

Step-by-step explanation:

We are given the sequence: 5, 7, 11, 19, 35,....

and we need to find the explicit definition that defines the sequence.

We are given

a₁ = 5

the common difference between terms d = 2

So, the formula will be:

aₙ=a₁+(n-1)d

aₙ=5+(n-1)2

aₙ=5+2n-2

aₙ=2n+5-2

aₙ=2n+3

So, Explicit definition of the given sequence is: aₙ=2n+3

Option A is correct

Answer:

a_{n}=2^{n}+3

Step-by-step explanation:

The given sequence is not arithmetic, it's a geometric sequence, that means the sequence is obtain using powers. The faster way to find the answer is to try options that fist with a geometric sequence. If we try the last one, we'll find that's the answer.

We need to try for n=1, n=2, n=3, n=4 and n=5:

a_{1}=2^{1}+3=5

a_{2}=2^{2}+3=4+3=7

a_{3}=2^{3}+3=8+3=11

a_{4}=2^{4}+3=16+3=19

a_{5}=2^{5}+3=32+3=35

Therefore, the right answer is the last choice, because as you can observe, it fits perfectly with the given sequence.

Answer:

The sample size is 183.

Step-by-step explanation:

Given:

σ = $1050, ppulatin standard deviation

99% confidence interval

Accuracy = +/- $200

The accuracy is given by

z*(σ/√n)

where

z* = 2.576 for 99% confidence level (from tables)

n = sample size

Therefore

2.576(1050/√n) = 200

√n = (2.576*1050)/200 = 13.524

n = 182.9

<em>The sample size is 183</em>

Use the Pythagorean identity on page 10 with x = 4 and y= 3 to generate a Pythagorean triple​
Dmitry [639]

Answer:

  c.  7, 24, 25

Step-by-step explanation:

For the formulas ...

  • a=x^2-y^2
  • b=2xy
  • c=x^2+y^2

we can use the given values of x and y to find the corresponding Pythagorean triple:

  a = 4^2 -3^2 = 16 -9 = 7

  b = 2·4·3 = 24

  c = 4^2 +3^2 = 16 +9 = 25

The generated Pythagorean triple is (7, 24, 25), matching answer C.
