what is the amount of sales tax for kevin's purchases?

enter your answer

$3.51

Step-by-step explanation:

Given : Kevin buys 4 folding chairs.

Each chair costs $13.50.

The sales tax  = 6.5% = 0.065

Cost of 4 folding chairs= 4 x Cost of one chair

Amount of Sales tax = 0.065 x Cost of 4 chairs    

=

Hence, the amount of sales tax for Kevin's purchases = $3.51

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
