For f(x) = 3x and g(x) = x + 2, find the following functions.
a. (fog)(x); b. (g of)(x); c. (fog)(4); d. (gof)(4)
a. (fog)(x) = 1
(Simplify your answer.)
b. (gof)(x) =
(Simplify your answer.)
c. (fog)(4) =
d. (gof)(4)= 1

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°

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
