a boat cost 12,050 and decreases in value by 12% per year. How much will the boat be worth after 9 years

Answers

Given:
Cost = 12,050
depreciation rate = 12%

year beginning value dep.rate depreciation ending value
1   12,050.00 12% 1,446.00    10,604.00
2   10,604.00 12% 1,272.48      9,331.52
3   9,331.52   12% 1,119.78      8,211.74
4   8,211.74   12%   985.41      7,226.33
5   7,226.33   12%   867.16      6,359.17
6   6,359.17   12%   763.10      5,596.07
7   5,596.07   12% 671.53      4,924.54
8   4,924.54   12%   590.94      4,333.60
9   4,333.60   12%   520.03      3,813.56

The boat will be worth $3,813.56 after 9 years.

Depreciation = beginning cost x depreciation rate
Ending cost = beginning cost - depreciation

Depreciation is the wear and tear of an object that decreases its value.

-- They're losing employees . . . so you know that the line will slope down, and
its slope is negative;

-- They're losing employees at a steady rate . . . so you know that the slope is
the same everywhere on the line; this tells you that the graph is a straight line.

I can see the function right now, but I'll show you how to go through the steps to
find the function. I need to point out that these are steps that you've gone through
many times, but now that the subject pops up in a real-world situation, suddenly
you're running around in circles with your hair on fire screaming "What do I do ?
Somebody give me the answer !".

Just take a look at what has already been handed to you:

0 months . . . 65 employees
1 month . . . . 62 employees
2 months . . . 59 employees

You know three points on the line !

(0, 65) , (1, 62) , and (2, 59) .

For the first point, 'x' happens to be zero, so immediately
you have your y-intercept ! ' b ' = 65 .

You can use any two of the points to find the slope of the line.
You will calculate that the slope is negative-3 . . . which you
might have realized as you read the story, looked at the numbers,
and saw that they are firing 3 employees per month.
("Losing" them doesn't quite capture the true spirit of what is happening.)

So your function ... call it ' W(n) ' . . . Workforce after 'n' months . . .

is W(n) = 65 - 3n .

2x2 + 6x + 5 = 0 what are the real roots for the quadratic equation

Answers

$2x^2 + 6x + 5 = 0$

$x= (-b+/- √(b^2 -4ac) )/(2a)$

$x= (-(6)+/- √((6)^2 -4(2)(5)) )/(2(2))$

$x= (-6+/- √(36 -40) )/(4)$

$x= (-6+/- √(-4) )/(4)$

$x= (-6+/- i√(4) )/(4)$

$x= (-6+/- 2i )/(4)$
