PLEASE HELP!!!

Answer:

The value of g(-1) is -2

Step-by-step explanation:

$g(x) = 2x^4 + 3x^3 - x^2$

Now we find g(-1)

To find g(-1) plug in -1 for x in the given g(x) equation

Replace all x by -1

$g(x) = 2x^4 + 3x^3 - x^2$

$g(x) = 2(-1)^4 + 3(-1)^3 - (-1)^2$

$g(x) = 2-3-1=-2$

The value of g(-1) is -2

azamat

9514 1404 393

Answer:

(d) 12.3

Step-by-step explanation:

From the Law of Cosines, you can solve for c:

c = √(a² +b² -2ab·cos(C)) = √(22.09 +104.2441 -95.974cos(105.3°))

c ≈ √151.659 ≈ 12.31499

Side c is about 12.3 units long.
