Solve the initial value problem:
dy——— = 2xy², y = 2, when x = – 1. dxSeparate the variables in the equation above:
Integrate both sides:
Take the reciprocal of both sides, and then you have
In order to find the value of
C₁ , just plug in the equation above those known values for
x and
y, then solve it for
C₁:
y = 2, when
x = – 1. So,
Substitute that for
C₁ into (i), and you have
So
y(– 2) is
I hope this helps. =)

Answer:
(-4,3)
Step-by-step explanation:
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
