hours

Step-by-step explanation:

We have been given Jazmyne decided to spend 6 1/2 hours studying over the weekend. She spent 1 1/4 hours studying on Friday evening and 2 2/3 hours on Saturday.  

To find the time Jazmyne needs more to reach her goal, we will subtract the sum of time spent on studying on Friday and Saturday from total time as:

Convert mixed fraction into improper fraction:

Make a common denominator

Combine numerators:

Therefore,Jazmyne needs to spend hours studying on Sunday in order to reach her goal.

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

i think it is c, not positive though
