- 2. If , and the vector is drawn with its tail at the point, find the coordinates of the point at the head of .arrow_forwardFor problems 1-3 determine if the statement is true or false. If true explain why, if false provide a counterexample. 1. The set of polynomials {1, x² + 3x4, 2x² – 7x4} is a linearly independent set in P4. 2. For vectors v1, V2, V3 in a vector space V and scalar k e R, Span{v1, v2, V3} = Span{v1, kv2, V3}. 3. Let v1, v2, V3 be vectors in a vector space V. If {v1, v2, V3} is linearly dependent then {v1, V2} is linearly independent.arrow_forwardThis is a linear algebra problem from section 1.3 "Homogenous Equations". All step work is greaty appreciated!arrow_forward
- A = ( ) -3. Find a non-zero number 1 and a non-zero vector x so that Ax = 1x. Note: There are only two possible values for 2. You just need to find one of them. For each 1 there are lots of vectors i. You just need to find a non-zero one. To get full credit, you must find your values systematically rather than guessing. Guess and check will receive partial credit.arrow_forwardplease include all steps and detailsarrow_forward1. Suppose a and bare vectors such that a x b = (1, 0, 2). What is bx -2a *x (-2a² a.

- Please solve all partsarrow_forwardLet A = - - 3 [1] [2] and b = 3 9 b2 Show that the equation Ax = b does not have a solution for some choices of b, and describe the set of all b for which Ax=b does have a solution. How can it be shown that the equation Ax=b does not have a solution for some choices of b? A. Find a vector x for which Ax=b is the identity vector. B. Row reduce the augmented matrix [ A b] to demonstrate that A b has a pivot position in every row. C. Find a vector b for which the solution to Ax=b is the identity vector. D. Row reduce the matrix A to demonstrate that A does not have a pivot position in every row. E. Row reduce the matrix A to demonstrate that A has a pivot position in every row.arrow_forwardPlease solve first 4 partarrow_forward

If they are dependent, find numbers, not all zero, that make the equation below true. You should be able to explain and justify your answer. 0 = (16 + 16x – 12x²)+ (-12 – 12x – 12x²)+ (18 + 18x – 3x?).arrow_forward
