Elijah decides to lease a $20,000 vehicle for two years. It is estimated that the car will be resold in two years at a price of $12,841, The Interest being charged is 41%. What is the financing foo?
$12.23
$43.87
$56.10
$68.33

thus, the first answer choice, y = sec x, is the correct one

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

a≈380.13mi² would be your answer if the radius was 11 miles
