it will take her 40 years to reach her goal.
Step-by-step explanation:
Answer:
Umer F. 51.43∘ is the measure of each exterior angle in a regular heptagon.
To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
The answer to this would be
In my personal opinion I'd say a gallon, just because when someone asks "How much lemonade is in that pitcher?" I think it's best to say a gallon over 16 cups(:
To take advantage of the characteristic solutions and , you can try the method of variation of parameters, where we look for a solution of the form
with the condition that
Then
Substituting into the ODE gives
Since
the above reduces to
and form a linear system that we can solve for using Cramer's rule:
where is the Wronskian determinant of the fundamental system and is the same determinant, but with the -th column replaced with .
So we have
Then the particular solution is
giving the general solution to the ODE,
