WebDetermine all values of the constant a such that the following function is continuous for all real numbers: ax f (x) = tanx, x 20 a2 -2, x<0 This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: 6. WebThe discriminant of the quadratic equation x 2 − ( 5 − k) x + ( k + 2) = 0 is Δ = k 2 − 14 k + 17. We want Δ to be always positive, then the given equation will always have two distinct real roots. For this to happen, the discriminant of Δ must be negative. But, the discriminant of Δ is Δ ′ = ( − 14) 2 − 4.17 = 128 > 0 is positive.

Web10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. WebSolve Using the Square Root Property x^2=81. x2 = 81 x 2 = 81.
