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.

Alekssandra [29.7K]

ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
