Debbie buys boxes of crackers that each has the same cost x. She represents the cost of 5 boxes of cheese crackers, 2 boxes of poppy seed crackers, and 2 boxes of plain crackers using the expression 5x + 2x + 2x. What equivalent expression can represent the cost?

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

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
