The amount of a certain element that remains after t hours can be determined using the expression below. Which expressions can be used to find the approximate amount of the element that remains after m minutes; 5(0.5)t/64

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°

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

zero

step-by-step explanation:
