The distance between the complex numbers z1 = 7 – 2i and z2 = 3 - 3i is

sqrt(17)

Step-by-step explanation:

the distance is

|(7-2i) - (3-3i)| = |4 + i|

remember, the absolute value of a complex number is

|a+bi| = sqrt(a²+b²)

in our case

sqrt(4² + 1²) = sqrt(16+1) = sqrt(17)

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
