Which of the following functions best describes this graph? A. y = x^2 - 5x + 6

B. y = x^2 + x - 12

C. y = x^2 - 8x + 15

D. y=x^2+ 8x + 15

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°

what are you trying to solve here

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
