1) a university wants to set up a scholarship fund that will pay out a $2500 annual scholarship for each of the next 50 years. if they can earn an average interest rate of 4%
compounded annually, how much do they need to invest now to fund the scholarship?

answer: what are the answer choices?

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

the rate of change is 25
