A + b = 90
a = 2b - 15
2b - 15 + b = 90
3b - 15 = 90
3b = 90 + 15
3b = 105
b = 105/3
b = 35 <== second angle
a = 2b - 15
a = 2(35) - 15
a = 70 - 15
a = 55 <== first angle
The LCM is 2x2x2x7 factorized
Answer:
here you go :)
Step-by-step explanation:
To round 0.833 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part. We use the following rules to round 0.833 to the nearest hundredth: A) If the last digit in the fractional part of 0.833 is less than 5, then simply remove the last the digit of the fractional part.
Is there more to the problem?
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,
