- If A and B are orthogonal, is A+B also orthogonal? Can you demonstrate Algebraically using A + B = (A + B)^T etc...? Thank you.arrow_forwardTrue or False Given an n-vector x, no more than 6.25% of entries can satisfy | xi | ≥ 4 rms(x)arrow_forwardFor 47, for two-dimensional vectors ⃗a and ⃗b , if‖⃗a‖= 2 and‖⃗b‖= 4, find‖⃗a + ⃗b‖for the given ⃗a ⋅ ⃗b .arrow_forward
- Let a, b, and x denote vectors in R,,. (a) Simplify 3a + (5b -2a) + 2(b - a). (b) If 5x - a = 2(a + 2x),solve for x in terms of a.arrow_forwardProve the following statement: If two vectors a and b are parallel, then a×b=0. (Express mathematically when it means for a and b to be parallel. Use the components for these two vectors.)arrow_forwardGiven that the acceleration vector is a(t) = (-1cos(-1t))i + (-1sin(-1t))j + (2t)k, the initial velocity is v(0) = i+k, and the initial position vector is r(0) = i+j+k, compute: A. The velocity vector v(t) = _i + _j + _k B. The position vector r(t) = _i + _j + _k The coefficients of the answers must be in in the form of expressions in the variable, e.g. 5cos(2t)arrow_forward
