You are adding chlorine to a swimming pool. You add 34 ounces of chlorine when you open the pool. During the week, 40% of the chlorine evaporates and so you have to add an additional 16 ounces weekly. a) Give a recursive definition for Cn, the amount of chlorine in the pool each week. Let C0 be the initial amount. b) Eventually, the amount of chlorine will level off to a stable amount. What is this amount

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

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
