Simply take the derivative of s(t),
s'(t) = -6
Since the velocity is constant, v(t) = s'(t) = -6 at any given time t.

Answer:
0.65359477124. this is probably the wrong answer so I'm just gonna guess u needed the answer the other way around because it makes more sense so 6.12 ÷ 4 = 1.53.
Step-by-step explanation:
Answer:
- A.) (3.6, 0.6)
- D.) (2.6, 0.4)
Step-by-step explanation:
See below for a graph.
___
Choices B, C, E can be eliminated on the basis that neither x nor g(x) can be negative. The domain of f(x) is x>0; the range of g(x) is x≥0.
70 / 35 = 2
So the 70 pound dog weights double the weight of the 35 pound dog, so he will eat twice as much.
2 x 2.5 = 5 cups
Meaning he will eat 5 cups of dry dog food a day.
By the same logic a 140 pound dog would have to eat twice what a 70 pound dog eats, that is 10 cups of dry dog food a day, so 7 1/2 cups are not enough.
Challenge: per pound a dog eats more than a cat. Since you know a 140 pound dog eats 10 cups, you can dive 140 by 10, to find out that each cup feeds 14 pounds, so half a cup would be the amount of food to feed a 7 pound dog, meaning that a dog weighing 1 pound less than a 8 pound cat would need the same amount of food, so it eats more than a cat.
