The sequence is: cos(π/2), cos (π ), cos (3π/2), cos ( 2π ),...
or: 0,-1,0,1,0,-1,0,1,... Since cos (nπ/2) oscillates between -1 and 1 as n tends to infinity, this sequence is divergent (limit does not exist).
D (38.63) because it wouldn’t make sense if the number was less than 10 when the line is clearly longer
Answer:66
Step-by-step explanation: 66 Diners promised to participate
1,013 is what each restaurant would donate
947 + x = 683 + 5x
-683 -683
264 + x = 5x
- x -x
264 = 4x
Divide 264 by 4 = 66
