Answer:
Step-by-step explanation:
1 ) Given that
For a non homogeneous part 
, we assume the particular solution is
2 ) Given that
For a non homogeneous part 
, we assume the particular solution is
3 ) Given that
y′′ + 4y′ + 20y = −3sin(2x)
For a non homogeneous part −3sin(2x) , we assume the particular solution is
4 ) Given that
y′′ − 2y′ − 15y = 3xcos(2x)
For a non homogeneous part 3xcos(2x) , we assume the particular solution is
Answer: If I remember correctly, the answer should be <em>y=-2(3)^x. </em>
Answer: 0.083
Step-by-step explanation:
Numbers on cube=6
faces on coin=2
Therefore, the total outcomes=
Now, the favorable outcome that he rolls a 4 and flips a head=1
The probability that he rolls a 4 and flips a head=
⇒The probability that he rolls a 4 and flips a head=
=0.083333\approx0.83.
Therefore, The probability that he rolls a 4 and flips a head=0.083
Answer:
Each bus could pick up 49 students
Step-by-step explanation:
(449-8):9=49
First, the ratio is 3:5. which means 3 redfish for every 5 bluefish. Since there are 20 bluefish, that means that is 4x more than 3:5. The total number of redfish are 12.
