Consider the following three vectors: A⃗ =(2,−1,1),
B⃗ =(3,0,5),
and
C⃗ =(1,4,−2).
Calculate the following combinations. Express your answers as ordered triplets [e. g., (9,4,−2)].

Part C

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
