The general solution (G.S.) of the Riccati DE is y(x) = cx² + u(x), and the explicit form of the IVP solution is y(x) = cx² + (2 - cx²)/x².
1. Rewrite the given DE as: y' = (y² + 2x⁴ - x²y) / Sx³.
2. Given that y1 = cx² is a particular solution, substitute it into the DE to find the constant c.
3. The general solution is y(x) = y1 + u(x), where u(x) is another function to be determined.
4. Substitute y(x) = cx² + u(x) into the DE and simplify the equation.
5. Recognize that the simplified equation is a first-order linear DE for u(x).
6. Solve the first-order linear DE to find u(x).
7. Combine y1 and u(x) to obtain the general solution y(x) = cx² + u(x).
8. Use the initial condition x²y' + y(1) = 2 to find the explicit form of the IVP solution.

Can someone please help me with this question?
Answer:
110 degrees
Step-by-step explanation:
Ok so no matter what the shape is, the exterior angles always have to add up to 360 degrees. Then, you can make the equation:
140 + 110 + x = 360
250 + x = 360
x = 110 degrees
Here's another way you can do it:
To do this, you can start by noticing that the top angle would be 40 degrees, because there's a straight line with 140 degrees and that angle, so you can do 180 - 140 = 40 degrees.
Then, the angle towards the bottom right would be 70 degrees using the same strategy:
180 - 110 = 70 degrees
The interior angles of a triangle always have to add up to 180 degrees, so you can do 180 - 40 - 70 = 70 to find the third interior angle of the triangle.
The last step is to do 180 - 70 = 110 to find the measure of the exterior angle at that point.

Solve for angle b and c
Answer:
46 degrees for both b and c
Step-by-step explanation:
the vertical angles postulate means that the opposite angle must be the same, so 134*2=268
since all angles must be 360, subtract 268, which is 92
using the vertical angles again, b and c are the same, and the sum must be 92
92 divided by 2 is 46
NOTE: Angles not necessarily drawn to scale.

Combine like terms
7k + 4(k + 4)
A.8k + 16
B.11k + 16
C.7k + 1k + 16
D.27k
Answer:
B. 11k + 16
Step-by-step explanation:
We have an expression and are asked to combine like terms.
To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.
(4(k) + 4(4))
4k + 16
7k + 4k + 16.
Since 7k and 4k are like terms since they end in the same variable, we can only add them.
7 + 4
11
11k + 16
