classify the real numbers as rational or irrational numbers.

Rational number                  Irrational number

3√25                                                           √141  

√256

Step-by-step explanation:

Since we know that

Rational number are those numbers which can be written in the form of and it is non terminating but recurring number.

Irrational numbers are those numbers which can not be written in the form of and it is non terminating and non recurring number.

3√25 = 3×5 = 15 is rational number.

is rational number because it is written in the form of

is rational number because it is non terminating but repeating number.

√256 = 16 is rational number

√141 is irrational number.

Hence, Rational number                  Irrational number

3√25                                                           √141  

√256

  about 5.52%

Step-by-step explanation:

If Lucius wants an account value of $2000 after 3 years, she can find the interest rate by solving the polynomial ...

  550x³ +600x² +650x -2000 = 0

This equation has one positive real root. It is irrational, so must be found using the rather complicated cubic solution formula or, more simply, a graphing calculator. The latter shows the root to be near 1.05516.

Lucius needs an interest rate of ...

  (1.05516 -1)×100% = 5.516%

The interest rate needed for a balance of $2000 after 3 years is about 5.52%.
