Find the distance from A(-8,-3,-2) and B(-4,8,0) , find ||AB||

RUDIKE [14]

Answer:

$||AB|| = 11.8743$

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$ . The distance between them is given by:

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

Distance from A(-8,-3,-2) and B(-4,8,0)

$||AB|| = \sqrt{(-4-(-8))^2+(8-(-3))^2+(0-(-2))^2}$

$||AB|| = \sqrt{4^2 + 11^2 + 2^2}$

$||AB|| = 11.8743$

Together Kate and Matt have 47 cards. If Kate and Zach combine cards they have 126. If Matt and Zach combine they have 93. How m

Ede4ka [16]

Answer:

Matt has 7 cards.

Step-by-step explanation:

Let K, M and Z represent number of cards that Kate, Matt and Zach have.

We have been given that together Kate and Matt have 47 cards. We can represent his information in an equation as:

$K+M=47...(1)$

We are also told that Kate and Zach combine cards they have 126. We can represent his information in an equation as:

$K+Z=126...(2)$

Further, Matt and Zach combine they have 93. We can represent his information in an equation as:

$M+Z=93...(3)$

Upon subtracting equation (3) from equation (2), we will get:

$K-M=126-93$

$K-M=33$

$K=33+M$

Upon substituting this value in equation (1), we will get:

$33+M+M=47$

$33-33+2M=47-33$

$2M=14$

$M=\frac{14}{2}=7$

Therefore, Matt has 7 cards.
