Answer: 11 years

Step-by-step explanation:

You can use the Rule of 72 which is a way to calculate quickly, the time it will take for an investment to double given its interest rate.

It works by:

= 72 / Interest rate

Rate is compounded quarterly so the periodic rate is:

= 6.56%/4

= 1.64%

Time taken to double = 72/1.64

= 43.9 quarters

In years that is:

= 43.9/4

= 11 years

What is the perimeter of a square whose diagonal is 3 square root 2? Show all work on how you got your answer

Alika [10]

Answer:

Step-by-step explanation:

Given: Diagonal of square= $3\sqrt{2}$

To find the perimeter of square, we need to find the length of sides of square.

∴ Using the formula of diagonal to find side of square.

Formula; $Diagonal= s\sqrt{2}$

Where, s is side of square.

⇒ $3\sqrt{2} = s\sqrt{2}$

Dividing both side by √2

⇒ $s= \frac{3\sqrt{2} }{\sqrt{2} }$

∴ $s= 3$

Hence, Length of side of square is 3.

Now, finding the perimeter of square.

Formula; $Perimeter= 4s$

⇒ $Perimeter= 4\times 3$

∴ $Perimeter= 12$

Hence, Perimeter of square is 12.
