An investment is worth $3518 in 1995. by 2000 it has grown to $5553. let y be the value of the investment in the year x, where x = 0 represents 1995. write a linear equation that models the value of the investment in the year x.
a. y = -407x + 7588
b. y = 1/407 x + 3518
c. y = -407x + 3518
d. y = 407x + 3518

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
