if they sell for 7.95 and you get 3.2 you do 7.95 times 3.2
Answer:
See below
Step-by-step explanation:
a) <u>Using the first two lines to get the equation:</u>
Since t = 0 represents a start point, the y-intercept is 163488
<u>Slope is:</u>
- (168392 - 163488)/10 = 490.4
<u>And the equation:</u>
- P(t) = 490.4(t - 1970) + 163488
b) Prediction of the population in 2012 using the function:
- P(2012) = 490.4(2012 - 1970) + 163488 = 184084.8
As we see the number we got is less than the one on the line 3 of the table. So the model underestimated the actual population.

For simplifying expressions of this sort, there are four rules of exponents that come into play;
__
I find it convenient to eliminate the fractions by adding the exponents, then rewrite any negative exponents as denominator factors.

Step-by-step explanation:
The area of a trapezoid can be found by using the following formula where "a" and "b" are the bases and "h" is the height of the trapezoid.
The perimeter can be found by adding the lengths of all sides. Therefore the perimeter of this trapezoid equals...
Perimeter = 3 + 11 + 5 + 7 = 26 units
