Best ResponseYou've already chosen the best response.2b(1000) + s(1500) = Equilibrium we just have to get a formula to equate b and to plug in

Best ResponseYou've already chosen the best response.2b(1000) + sqrt(20^2 + (bx)^2)(1500) = E solve for b right?

Best ResponseYou've already chosen the best response.2maybe better like this tho: when b(1000) = s(1500) b(1000) = sqrt(20^2 + (bx)^2)(1500) b(1000)/1500 = sqrt(20^2 + (bx)^2) 2b/3 = sqrt(20^2 + (bx)^2) ; ^2 both sides

Best ResponseYou've already chosen the best response.24b^2  = 400 + (bx)^2 9 4b^2  = 400 + b^2 2bx +x^2 9 4b^2 = 9(400 + b^2 2bx +x^2) 4b^2 = 3600 + 9b^2 18bx +9x^2

Best ResponseYou've already chosen the best response.24b^2 = 3600 + 9b^2 18bx +9x^2 0 = (5)b^2 (18x)b + (9x^2 + 3600) perhaps?

Best ResponseYou've already chosen the best response.2to solve for b we can use the quadratic formula and insert all this other stuff as parameters

Best ResponseYou've already chosen the best response.218x sqrt(324x^2  4(5)(9x^2 + 3600))  +  and simplify lol 10 10

Best ResponseYou've already chosen the best response.0holy bageezus ... i uderstand the transitions and all ..and everything your doing ..but what are parameters?

Best ResponseYou've already chosen the best response.2parameters are just the values we plug into the quadratic formula to make this easier; they relate to the coeffs of the b values

Best ResponseYou've already chosen the best response.2sqrt(144x^2  72000) the innards here factor to what: sqrt(144(x^2  500)) 12 sqrt(x^2  500) if i did that part right lol

Best ResponseYou've already chosen the best response.2our options for b are then: 9x 6sqrt(x^2  500)  +  right? 5 5
