Signal mistakenly produced 1,000 defective cell phones. the phones cost $60 each to produce. a salvage company will buy the defective phones as they are for $30 each. it would cost signal $80 per phone to rework the phones. if the phones are reworked, signal could sell them for $120 each. assume there is no opportunity cost associated with reworking the phones. compute the incremental net income from reworking the phones.

Number of defective cell phone produced = 1000.

Defective phones cost $30 each.

Cost of defective phones =30x1000=30,000.

Cost of producing 1000 cell phones = 60x1000=$60,000.

Cost of rework= 80x1000=80,000.

Rework phone sale value =120x1000=120,000.

Incremental net income = 120,000-80,000-30,000= $10,000.

The  incremental net income from reworking the phones is $10,000.

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
