Hans invests $550 at a rate of x% per year compound interest. At the end of 10 years, the value of the investment is $638.30, co
cricket20 [7]

Answer:

1.5%.

Step-by-step explanation:

x per cent is written as 0.01x as a decimal fraction.

638.30 = 550(1 + 0.01x)^10

(1 + 0.01x)^10 = 638.30/550

Taking logarithms:

10 ln (1 + 0.01x) = ln ( 638.30/550)

ln (1 + 0.01x) =  ln ( 638.30/550)/ 10

ln(1 + 0.01x) = 0.014889

Converting the logs:-

1 + 0.01x = e^0.014889 = 1.015

0.01x = 1 - 1.015

0.01x = 0.015

x = 0.015/ 0.01

= 1.5.

Negative numbers do not have square roots that are real numbers
MatroZZZ [7]

Answer:

Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

The answer is: B. (If you subtract 11.4 - 6.8, you get 4.6. B is the only answer that shows this.) While all of the answers show mental math, only B gives you the correct answer.
