Answer:
f'(t) = -15 tons/second
Step-by-step explanation:
Using the power rule, the derivative of f(t) is ...
f'(t) = -15 . . . tons/second
f(t) is the fuel weight, so f'(t) is the rate at which fuel weight is changing. The rocket is using fuel at the rate of 15 tons per second.
_____
<em>Comment on units</em>
The units of the equation for f(t) are ...
f(t) = 2520 tons - (15 tons/second)(t seconds)
The derivative is the coefficient of (t seconds), so is (-15 tons/second).
Answer:
1. 88 - b
Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.
2. 73 + d
Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.
3. 23 x g
Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.
Answer:
9(413)2= 7434 and 6(593)=3558

I'm thinking it's a parabola since you can cover a vast amount of apace within the parabola too.
Hey, looks like when she doesn't study, she ALWAYS fails. Don't mean to insult though.
Let's see the difference between the three numbers. 63-58=5. 68-63=5.
We know the difference between each assessment she scores is 5 now!!
Let's put it to use.
Although you don't have multiple choice answers...
after 4 assessments(not including first 3), her score will be above 85!!
Including the first 3 assessments, her score would be above 85 after 7 assessments!!
anyways, I hope this helps!!
