Two brothers, Mark and Charles, each inherit $31000. Mark invests his inheritance in a savings account with an annual return of
Nutka1998 [239]

Answer:

$1,085

Step-by-step explanation:

Data provided in the question:

Amount inherited and invested i.e principle = $31,000

Annual return for Mark on savings account = 2.9% = 0.029

Annual return for Charles on CD = 6.4% = 0.064

Now,

The Interest earned by Mark in 1 year = principle × Rate × Time

= $31,000 × 0.029 × 1

= $899

The Interest earned by Charles in 1 year = principle × Rate × Time

= $31,000 × 0.064 × 1

= $1,984

Therefore,

More Money that Charles have than Mark = $1,984 - $899

= $1,085

Solve x2 – 12x + 59 = 0 for x.
mr_godi [17]
59 is a tough bird to deal with; its only factors are 1 and 59.

Thus, forget about factoring.  Instead, use the quadratic formula, or solve the equation by completing the square.

Please note:  x2 is ambiguous.  Please write x^2 to indicate "the square of 2."

Here you have 1x^2 - 12x + 59 = 0, for which a=1, b=-12 and c=59.

Use the quadratic formula:  x=[-b plus or minus sqrt(b^2-4ac)] / (2a)

to find the two roots.  Notice that the "discriminant" b^2 - 4ac will be negative, meaning that your two roots will be "complex."
