O
A. f(n) = 4.3n-1
OB. f(n) = 31-1
o C. f(n) = 4"-1
OD. f(n) = 3.41-1

Plz hurry evaluate the expression a+b where a=8 and b=19

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.

Alex measured the length of an item to be 3.7 cm. the actual length is 3.5 cm. what is alex’s percent error?
