prove that 5^(2n - 1) is divisible by 8​

Answers

Answer 1

Answer:

Step-by-step explanation:

Prove that 52n − 1 is divisible by 8 for all n ∈ N.

Solution

To prove by induction, we must

1. Show it is true for n = 1

2. Assume true for n and prove it is true for n + 1.

Let P(n) be the statement 52n − 1 is divisible by 8.

When n = 1, 52 − 1 = 24, which is divisible by 8.

This proves P(1).

Suppose that P(n) is true, i.e., 52n − 1 is divisible by 8.

Then 52(n+1) − 1 = 52

· 5

2n − 1 = 52

(52n − 1) + (52 − 1).

Note that 52n −1 is divisible by 8 using P(n) and also 52 −1 = 24 is divisible

by 8. Thus we have proved that P(n + 1) is true.

We conclude that P(n) is true for all n ∈ N.

A bank offers 2% simple interest per year. A woman opens an account with deposit of 900 pounds. She closes the account 2 years later. How much will she withdraw.

Answers

simple interest formulae = PRT/100

where

p stands for percentage (2%)

r stands for rate ( 900)

t stands for time (2 years )

2×900×2/100

=3600/100

=36

Deposit interest

Level : SHS Keyword : deposit interest, simple interest

Deposit Interest in 2 years

= D × i × T/365 days

= 900 pounds × 2% × (365 × 2 years)/365 days

= 900 pounds × 0.02 × 730 days/465 days

= 900 pounds × 0.02 × 2

= 36 pounds

Her Deposit in 2 years

= 900 pounds + 36 pounds

= 936 pounds

So, her deposit if she will withdraw is 936 pounds

The area of a square is 676 square feet. what is the perimeter of the square?

Answers

Given : The area of a square is 676 square feet. what is the perimeter of the square?

Solution :

Area of Square = 676 ft²

Let's assume the constant multiple be α (alpha)

Length × Breadth = 676

α × α = 676

α² = 676

α = √676

α = 26

So, now getting perimeter

As we know that, Perimeter = 4(Side)

Perimeter = 4(26)

Perimeter = 104

Henceforth, the perimeter of square is 104 ft

[tex]\sqrt{11}[/tex] = 3.3166

We can see that [tex]\sqrt{11}[/tex] is 0.3166 greater than 3, and 0.1751 greater than pi. Therefore, it's the biggest number.

Pi is second biggest because it is less than [tex]\sqrt{11}[/tex] but greater than 3.

Therefore, your order would be:
