C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))
For the top question, the answer is D
Because 16 divide by 4, equals 4
The output is the y value. So look at the plotted points and then take out the x values. Put the y values in order. The answer is the fourth answer choice.
Answer:
D
