If A =`[[2,4],[-1,k]]` , and` A^2=0` find the value of k

If A=[[2,4],[-1,k]] and A^2=0 , rhen find the value of k

If A=[[2,4],[-1,k]] and A^2=0 then find k

If A=[[1, 2],[ 4, 2]], then find the value of k if |2A|=k\ |A|

If A=[{:(0,2),(3,-4):}] and k A =[{:(0,3a),(2b,24):}], then find the value of b-a-k.

If int_0^1(3x^2+2x+k)dx=0, find the value of k

If the middle point of the line segment joining (3, 4) and (k, 7) is (x, y) and 2x+2y+1=0 , find the value of k .

If K is constant such that xy + k = e ^(((x-1)^2)/(2)) satisfies the differential equation x . ( dy )/( dx) = (( x^2 - x-1) y+ (x-1) and y (1) =0 then find the value of K .

If 1/2 is a root of the equation x^2+kx-5/4=0, then find the value of k.

Find the point of intersection of the lines 4x + 3y = 1 and 3x - y + 9 = 0 . If this point lies on the line (2k - 1) x - 2y = 4 , find the value of k. The above question can also be stated as : If the lines 4x + 3y = 1, 3x – y + 9 = 0 and (2k - 1) x - 2y = 4 are concurrent (pass through the same point), find the value of k.

If A A=[3-2 4-2] and I=[1 0 0 1] , find k so that A^2=k A-2I .
