(D)-2

Step-by-step explanation:

The degree of a term in a polynomial is the power of the variable in that term.

In the polynomial:

The coefficient of the term of degree 2 is the number beside x raised to the power of 2.

This coefficient is -2.

The correct option is D.

D. -2

Step-by-step explanation:

Let order the polynomial in standard form:

The value of the coefficient in the second-degree term is -2. Hence, the right answer is D.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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°
