A concert promoter models the profit from her next concert, P dollars, by the equation: P=-11(t-55)^2+10571 a)How much should she charge per ticket to break-even? b)What price maximizes her profit? c)What is the maximum price she can charge before losing money? Show this step by step please?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
