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)

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

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

$||AB|| = 11.8743$

Evaluate -2x^2-4x+3 when x=-2

Misha Larkins [42]

Answer:

Step-by-step explanation:

A polynomial is sometimes easier to evaluate if it is first written in Horner form:

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

For x = -2, this is ...

(-2(-2) -4)(-2) +3 = 0(-2) +3 = 3

The value is 3 when x = -2.

Solve -5t = 60 65 -6 6 55

defon

When you are asked to solve an equation, you need to isolate the variable which is t in this case. To isolate t, you would divide both sides by -5 and be left with t=-6 which is the final answer.

I hope this helps.
