The temperature dropped 2 °f every hour for 6 hours. what was the total number of degrees the temperatur changed in the 6 hours

assuming that the starting temperature is 0 degrees F, the answer would be -12 degrees F

Step-by-step explanation:

Simply multiply 2 by 6 to get 12, and since the temp is dropping that means its below freezing and you have to put a negative sign in front of it.

correct answer:

b.(19,-2)

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°
