Describe the span of the given vectors geometrically and algebraically. u = 1 3 0 , v = 6 3 −1 (a) geometrically 1.The set of all linear combinations of u and v is the line through the origin with u as the direction. 2.The set of all linear combinations of u and v is a plane through the origin containing u and v as direction vectors. 3.The set of all linear combinations of u and v is a plane through the origin containing only v as a direction vector. 4.The set of all linear combinations of u and v is a plane through the origin containing only u as a direction vector. 5.The set of all linear combinations of u and v is the line through the origin with v as the direction.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

any options?

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
