Suppose the total benefit of watching 1 baseball game is 100, the total benefit of watching 2 games is 120, and the total benefi

77julia77 [94]

Answer:

A. 5

Step-by-step explanation:

The marginal benefit of an article, $B_m$ is calculated as:

$B_m=\frac{DB_t}{DQ}$

Where $DB_t$ is the change in the total benefit of the article, and $DQ$ is the change in the units of the article.

If we want to know the marginal benefit of watching the 3rd game, we need to use the information of total benefit of watching 2 games and 3 games.

In this case, the total benefit of watching 2 games is 120 and the total benefit of watching 3 games is 125, so $DB_t$ and $DQ$ are equal to:

$DB_t=125-120=5$

$DQ = 3 - 2 = 1$

Then, the marginal benefit of watching the third game is:

$B_m=\frac{5}{1}=5$

For the functions f(x)=−7x^2−x and g(x)=9x^2−4x, find (f−g)(x) and (f−g)(1)

musickatia [10]

Answer:

See below.

Step-by-step explanation:

$f(x)=-7x^2-x\\g(x)=9x^2-4x\\(f-g)(x)=f(x)-g(x)\\(f-g)(x)=(-7x^2-x)-(9x^2-4x)\\(f-g)(x)=-7x^2-x-9x^2+4x\\(f-g)(x)=-16x^2+3x\\\\(f-g)(1)=-16(1)^2+3(1)\\(f-g)(1)=-16+3=-13$
