nlexa [21]

The answer choice which explains whether the function is a direct variation or not is; This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

<h3>Which explains whether or not the function represents a direct variation?</h3>

It follows from the task content that the function passes through the origin and hence, if the function was represents as a linear function, it's y-intercept would be zero.

Furthermore, the slope, otherwise termed it's rate of chage is constant and is evaluated as; $5 per hour. Hence, the aforementioned form the basis for the classification of the function as a direct variation.

Helen [10]

Answer:

x^4 + 4x^3 + 6x^2 + 7x + 2

Step-by-step explanation:

We are asked to multiply the given polynomials.

(x^ 2 + 3x + 1) \times (x^2 + x + 2)

Multiply each term of the first polynomial to each term of the second polynomial.

x^ 2  \times (x^2 + x + 2) = x^4 + x^3 + 2x^2

3x  \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x

1 \times (x^2 + x + 2) =  x^2 + x + 2

Add the results

(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)

Combine the like terms

x^4 + 4x^3 + 6x^2 + 7x + 2

The answer is written in descending powers of x.
