Explanation:
Firs you should consider that if its exponential then it has some form similar to
3
x
. Where we have some known part (3) and the unknown part (
x
) that we are trying to find out. Mathematically we can say it has the form
a
x
. In this case we know what the
a
is and that is the entire population that was given to us. We know over time it will change but why are we even using the exponential model.
Well it turns out that if you multiply some value over and over again it has this form. Example we multiply
2
⋅
2
⋅
2
⋅
2
=
2
4
. So if something doubled over time then this is what would happen.
Now the problem is that it will continue to decrease at the same rate leading to
a
⋅
(
.94
)
because only
94
%
of the population remains each year. After two years

According to the rules of significant figures in counting the number of significant figures when dealing with the measurement, especially when it is scientifically measured, you must consider 2 zeros at the right of the period. For example, in 98.00 there are 4 significant figures
<span>Let each side perpendicular to the river be
"x".
Then the side parallel to the river is "2400-2x".</span>
The function would be:
<span>A(x) = x(2400-2x)
</span>
And it would be: A(x) = 2400x - 2x^2
To solve the equation:
<span>
You have a quadratic with a = -2 and b = 2400
</span>
Maximum Area happens where:
x = -b/2a
= -2400/(2*-2)
<span>= 600 ft. (width)
</span>
To find the length it will be:
<span>= 2400-2x = 2400-2*600 = 1200 (length)</span>
Since there is a shortage in the budget in 2005 by 553,656,965,393.18, the total debt that of the United States in 2005 will be the public debt by 2004 added with this deficit in the budget. Having said that, the public debt by 2004 should be equal to,
$ 7.9327 x 10^12
