Answer:
<h2>36 minutes</h2>
Step-by-step explanation:
<u>$0.59 for the first minute</u>
11.84 - 0.59 = 11.25
1 Minute
<u>An additional roaming charge of $2.50</u>
11.25 - 2.50 = 8.75
<u>$0.25 for each additional minute</u>
8.75 / 0.25 = 35
1 + 35 = 36 minutes.
<em>Multiply it back out to check it's right.</em>
2.50 + 0.59 + (35 * 0.25) = 11.84
Standard reduction of order procedure: suppose there is a second solution of the form
, which has derivatives
Substitute these terms into the ODE:
and replacing
, we have an ODE linear in
:
Divide both sides by
, giving
and noting that the left hand side is a derivative of a product, namely
we can then integrate both sides to obtain
Solve for
:
Now
where the second term is already accounted for by
, which means
, and the above is the general solution for the ODE.
Answer:
3x-4/14=9/10
You change the subtraction to addition
3x+4/14=9/10
Then you change the fractions to decimals
Step-by-step explanation:
You can’t tell because it might be more than 1 pound, but you can say it’s at least 1 pound.
