An architecture firm creates blueprints for office buildings. last week, they produced four rectangular blueprints for four different projects. project a: a 20-inch by 15-inch blueprint with a scale of 1 inch to 4 feet and a projected cost of $22,000. project b: a 10-inch by 8-inch blueprint with a scale of 1 inch to 8 feet and a projected cost of $25,000. project c: a 15-inch by 12-inch blueprint with a scale of 1 inch to 6 feet and a projected cost of $27,000. project d: an 8-inch by 6-inch blueprint with a scale of 1 inch to 12 feet and a projected cost of $30,000. order the projects from greatest to least projected cost per square foot of the actual offices. project c project b project d project a

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

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
