Answer:
yes, the discount is more than 30%
Step-by-step explanation:
The price change percentage is ...
%change = ((new price)/(old price) -1) × 100%
= (44.20/68 -1) × 100%
= -0.35 × 100% = -35%
The jacket was marked down 35%, so matches the ad description.
a) r = √(1² + (-5²)) = √26 = 5.09901...
θ = tan⁻¹(-5/1) = 4.9097... radians
(5.1, 4.9)
b) r = - 5.09901...
θ = 4.9097... - π = 1.76819...
(-5.1, 1.8)
7238.2
V = = 7238.2
