Answer is:
x^3-2x^2-8x+21
8.50 is already a rational number last time I checked since a<span> </span>rational number<span> is any whole </span>number<span>, fraction, mixed </span>number<span> or decimal. </span>
A population of size P increasing at the rate of 2% may be modelled as follows
P = P0<span> e</span>0.02 t<span> , where t is the number of years after t = 0 and P</span>0<span> is the population at t = 0. </span>
Let t = 0 corresponds to January 1, 2000 and therefore t = 4 corresponds to December 31. But P is 2,000,000 when t = 4. Hence
2,000,000 = P0<span> e</span>0.02*4
<span>Solve the above for P0</span>
P0<span> = 2,000,000 / e</span>0.02*4<span> = 1 846 000 (rounded to the nearest thousand) </span>
<span>P0 is the population at t = 0 or on January 1, 2000.
A. is the correct answer</span>
Answer:
0.8
Step-by-step explanation:
(-w+0.4)+(w+0.4)
