It is estimated that approximately one-half of all aluminum cans will be recycled each year. if a soft drink company produces 350,000 cans one year, how many cans are still in use after 4 years of recycling and re-using, using this function? nt = 350,000(0.52)t a 87,500 b 25,591 c 175,000 d 21,875

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
