Law of sines: sin(A)/a= sin(B)/b= sin(C)/c. Which represents the value of c? Oc= (3) sin(40)/sin (45)
Oc= (3) sin(45)/(40)
Oc=sin (40)/(3) sin(45)
Oc=sin (45)/(3) sin(40)

If set d is not the empty set but is a subset of set e, then which of the following is true? d ∩ e = d d ∩ e = e d ∩ e = ∅

Use the ratio test to determine whether ∑n=14∞n+2n! converges or diverges. (a) find the ratio of successive terms. write your answer as a fully simplified fraction. for n≥14, limn→∞∣∣∣an+1an∣∣∣=limn→∞.
