Afamily of three goes to a salon. each person gets a haircut and highlights. the cost of each haircut is $15, and the cost per person for highlights is $x$ dollars. write and simplify an expression that represents the total cost (in dollars) for the family at the salon.

45+3.x

Step-by-step explanation:

Each person gets a haircut --> 3.15= 45

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

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
