<span>For the answer to the question above, We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A. tan(θ) = 300.5/400. θ = tan^-1(300.5/400). So the answer is θ = 36.9°. I hope my answer helped you.</span>
The function representing the price of the ring x years after 2000 is f(x) = (100 + 35)/100 *x + 590 = 135/100 *x + 590 = 1.35x + 590 i.e. f(x) = 1.35x + 590
