2. ### Solve the system of equations below by graphing them. what are the ordered pairs ( u , b)?

u = -b + 21 u = -2b + 30 Check it out - both equations are ... u " already. Thus, -b + 21 = -2b + 30 -b + 2b = 30 - 21 b = 9. u = -b + 21 = -(9) + 21 = 12 u = -2b + 30 = -2(9) + 30 = 12 So, the ...

6. ### Find the exact values of sin( u /2), cos ( u /2), tan ( u /2) using the half angle formulas?

sin( u / 2) = sqrt( (1 - cos( u )) / 2) cos( u / 2) = sqrt( (1 + cos( u )) / 2) tan( u / 2) = sin( u /2) / cos( u /2) = sqrt...sqrt( (8/5) / 2) = sqrt( 4/5 ) = 2 / sqrt(5) = 2 * sqrt(5) / 5 sin( u /2) = 2 * sqrt(5) / 5 sqrt( (1 - 3/5) / 2) = sqrt( (2/5) / 2...
