Assume a solution of the form
. Taking the differential of both sides would give the ODE

where
and
. The ODE is exact if
. We have


so the ODE is not exact. However, multiplying both sides by
gives

and now


so the ODE is now exact.
Now,


So the ODE has solution

or simply

X = 12400
20/100 = 1/5
2480 x 5 = 12400
Answer:
20 × 10 = 200
Step-by-step explanation:
Multiply 2 × 1 = 2 and then add the two zeros onto the end to get 200.
For
y=a(x-h)^2+k
vertex is (h,k)
given
y=1(x-2)^2-5
the vertex is (2,-5)
tha'ts quadrant 4
andswer is 2nd one
