F(x)=x^3-2x+6 g(x)=2x^3+3x^2-4x+2 Find (f-g)(x).

1 answer:

7 0

(f-g)(x) = f(x) - g(x)
= (x^3 -2x+6) - (2x^3+3x^2-4x+2)
= x^3 -2x +6 -2x^3 -3x^2 +4x -2 . . . . distribute the negative sign
= (1-2)x^3 -3x^2 +(-2+4)x +(6-2) . . . . . combine like terms

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

Find the magnitude of wx for w(6 -3 6) and x(6 3 4)<br> A. 2sqrt10<br> B. 35<br> C. 4sqrt2<br> D. 32

gladu [14]

Answer:

$|WX|=2\sqrt{10}$

Step-by-step explanation:

To find the distance between two points in there dimensional coordinate system, we use the formula;

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}$

The magnitude for w(6 ,-3 , 6) and x(6, 3, 4)

$|WX|=\sqrt{(6-6)^2+(3--3)^2+(4-6)^2}$

$|WX|=\sqrt{(0)^2+(6)^2+(-2)^2}$

$|WX|=\sqrt{0+36+4}$

$|WX|=\sqrt{40}$

$|WX|=2\sqrt{10}$

The correct choice is A.
