Show that the differential equation is homogeneous. Find the particular solution of this differential equation, given that x =1 when

Find the vector equation of the plane determined by the points A (3, –1, 2), B (5, 2, 4) and C (–1, –1, 6). Also find the distance of point P (6, 5, 9) from this plane.

Write the degree of the differential equation

A speaks truth in 75% of the cases, while B in 90% of the cases. In what percent of cases are they likely to contradict each other in stating the same fact?

Do you think that statement of B is true?
