Which ordered pair(s) satisfy the function f(x)=-x^2+2? Select all that apply
A.(-1,1)
B.(-1,-1)
C.(-2,-2)
D.(2,-2)
E.(-2,2)

the 3rd option is right

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°

it can increase the size of the tip you would spend, since it's adding to the money you'd already have to pay.
