Give me a second and I can see what I can do
<span>This can be represented by the equation d = 35 + 45x, where d is the distance from the terminal and x is hours of travel. At the beginning of the journey the train had travelled 0 hours, so x = 0. Therefore, d = 35 + (45 x 0). D = 35 + 0. The train is 35 miles from the terminal.</span>
x greater than negative 2, because ln(x) is undefined for x <= 0 (-2+2=0, -1.999...+2>0)
Answer:
a) 580 - 16n
b) 9850 - 271.72n
Step-by-step explanation:
a) starting number of bales = 580
each day, the farmer feeds out 2 bales of hay to each yard. he has 8 yards, so he feeds out 2 bales 8 times for a total of 2 * 8 = 16 bales. Therefore, he loses 16 bales each day
After the first day, he has 580-16 = 564 bales. After the second, he has 564-16 = 548 bales, and so on. He loses 16 bales n times for n days, and as a result, his final amount of bales is
original amount - amount lost = 580 - 16n
b)
First, we can calculate how much a bale weighs.
average = sum/count = 9850 kg / 580 ≈ 17 kg
Therefore, as he loses 16 bales of hay, he loses 17 kg 16 times, or approximately 271.72 kg of hay every day. For n days, he loses 271.72n kg. This brings his final amount to be
starting - amount lost = 9850 - 271.72n
