A syllabus for a course states that you can earn 450 points on homework,100 points on attendance, and 800 points on exams. What percentt of the final grade is determined by attendance? (nearest percent)

7

Step-by-step explanation:

Homework         450

Attendance        100

Exams                800

Total                 1350

% = 100 * 100/1350

% = 100 * 0.07407

% = 7.407%

% = 7%

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
