How to calculate square root 1.4 without calculator
Oxana [17]

Answer:

Approximate only

Step-by-step explanation:

the perfect square smaller than 1.4 is 1, because 1^2 =1

Take the difference between the two, 1.4 -1 = 0.4

Put the whole with 1. the part will be as follow:

1 \frac{0.4}{double~the ~whole} =1\frac{0.4}{2}

=1+0.2= 1.2

Note: just approximate!! with calculator, it is 1.18321

A couple deposits $20,000 into an account earning 5% annual interest for 30 years. Calculate the future value of the investment
makvit [3.9K]

The future value of the investment if the interest is compounded monthly is $89,354.89.

<h3>What is the future value of the investment?</h3>

Given that;

  • Principal P = $20,000
  • Annual interest rate r = 5% = 5/100 = 0.05
  • Time t = 30 years
  • Compound monthly = 12
  • Future value = A = ?

Using the compound interest formula;

A = P( 1 + r/n )^(nt)

We plug in our values.

A = 20000( 1 + 0.05/12 )^(12 × 30)

A = 20000( 1 + 0.0041666666666667)^(360)

A = 20000( 1.0041666666666667)^(360)

A = 20000( 4.46774965 )

A = 89354.89

Therefore, the future value of the investment if the interest is compounded monthly is $89,354.89.
