F(x) = 5x + 7, g(x) = x + 9. find f(g( can someone just explain to me how you would go about solving a problem like this? i’m confused.

Hello!

As we are not given an x-value, we are just going to have our answer be written in terms of x.

We want to find the f of g(x). As you can see, the g(x)=x+9. Let's plug this value into the function f to find our answer.

f(g(x))=5(x+9)+7

f(g(x))=5x+52

Therefore, our answer would be f(g(x))= 5x+52

I hope this helps!

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°
