Express the vector R~ A B C D P R in terms of A~ , B~ , C~ , and D~ , the edges of a parallelogram. 1. R~ = C~ + D~ 2. R~ = A~ − B~ 3. R~ = A~ − C~ 4. R~ = A~ + D~ 5. R~ = B~ + D~ 6. R~ = B~ − A~ 7. R~ = A~ − D~ 8. R~ = B~ + A~ 9. R~ = D~ − A~ 10. R~ = C~ + B

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.
