|suppose that the auxiliary equation of au 5 (x)by(4(x) cy' '(x)dy' '(x)ey'(x)fy(x) multiplicity 2), r = 3, and r = 12 i. select all possible linearly independent solutions of the differential equation = 0 has solutions of r = 8 (with oy=9e3t cos(12t) -e 3t y6 sin(12t) yet sin(12t) y4 cos(12t) = - 3test y9est y= - 10e3

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

about 168 miles
