A population of bears decreases exponentially.

timurjin [86]

Answer:

0.8

Step-by-step explanation:

The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...

factor = (year 1 population)/(year 0 population) = 320/400

factor = 0.8

there are four semi trailer trucks parked in a line at the rest stop after the first truck each truck in the line weighs 2 tons

alexira [117]

Call the weght of the first truck " $w_{1}$ ". We then know that the truck after that is 2 tons more, and the next and the next. i.e:
$w_{2} = w_{1} + 2$
$w_{3} = (w_{2} + 2) = (w_{1}+4)$
$w_{4} = (w_{3} + 2) = (w_{1}+6)$

We also know that total is 32 tons.
$w_{total} = 32 = (w_{1}) + (w_{2}) + (w_{3}) + (w_{4})$
$32 = (w_{1})+(w_{1}+2)+(w_{1}+4)+(w_{1}+6)$
$32= 4(w_{1})+12$
$20=4(w_{1})$
$w_{1} = 5 tons$

Therefore the trukcs weigh 5,7,9 and 11 tons for a total of 32 tons.

Converting to pounds, the trucks weigh 10,000, 14,0000, 18,0000 and 22,000 pounds.
