<h2>13</h2>

Begining with the third term, each term of the sequence is the sum of the preceding two.

  • 1+1 = 2
  • 1+2 = 3
  • 2+3 = 5
  • 3+5 = 8
  • 5+8 = 13

I'm not really looking for an exact answer, I'm more so looking for an explanation on how to do this.

I would have each block be 1/6 of a yard

You could technically have any value you want, but for me 1/6 is easiest because 1/2 and 1/3 will scale up to this like so

1/2 = (1/2)*(3/3) = 3/6

1/3 = (1/3)*(2/2) = 2/6

The diagram below might help if you're still stuck on why I picked 1/6.

Kamil invests 9000 for 4 years his investment pays compound interest of x% per anumn
elena-s [515]

To get the Total amount upon investment for the compound interest, plug in the value of x into the given expression bellow

<em>A = 9,000.00(1 +  x/100)^(4)</em>

Given data

Principal = $9000

Time = 4 years

Rate = x% per annum

<h3>Solution</h3>
  • Step one:

First, convert R as a percent to r as a decimal

r = x/100

r = x/100

  • Step two:

Then solve the equation for A

A = P(1 + x/100)^t

A = 9,000.00(1 + x/100)^(4)

A = 9,000.00(1 +  x/100)^(4)

  • Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of x% per year.
