If f(x)=3x+5 and g(x)=-x-2, determine f((g(x))​

f(g(x)) = -3x - 1

Step-by-step explanation:

f(g(x)) = 3(g(x)) + 5

f(g(x)) = 3(-x-2) + 5

f(g(x)) = -3x - 6 + 5

f(g(x)) = -3x - 1

f((g(x)) = -3x - 1

Step-by-step explanation:

3(-x-2)+5 =

-3x-6+5 =

-3x-1

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°

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
