For problems like these, it's very helpful for looking at key words. 'How many more' suggests that one value is greater than the other by a certain amount, which means subtraction. Let's do the same for this equation.
If 165 is m greater than 130, then this means .
This will also mean that m is 130 less than 165. To solve this, isolate the variable and subtract 130 from both sides:
We will end up with m = $35. To prove this, plug 35 into the m value as shown below:
, so the answer is $35 more is needed.
I'll assume that's an exponent at the end there:
The first derivative gives the velocity. The second derivative gives the acceleration; increasing velocity is the same as positive acceleration. So we want to find when the second derivative is positive.
Let's see if we can use to avoid multiplying this out.
That worked; let's do it again:
That's a nice parabola. It's zero or negative for so positive everywhere else:
Answer: Increasing velocity when t < 1 or t > 3
