What is the cross product of

< 3, 1, - 6 >

< - 2, 1, 8 >

https://socratic.org/questions/what-is-the-cross-product-of-3-1-6-and-2-1-8

< 14, - 12, 5 >

Explanation: we want

< 3, 1, - 6 > \times < - 2, 1, 8 >

this is found by calculating the determinant

∣ ∣ ∣ ∣ ∣ ∣ ∣ \hat{i} 3 - 2 \hat{j} 11 \hat{k} - 6 8 ∣ ∣ ∣ ∣ ∣ ∣ ∣

What is the projection of

< 0, 2, - 2 >

< 3, - 6, 7 >

P r o j_{v} u = \frac{- 2 6}{9 4} < 3, - 6, 7 >

< \frac{- 7 8}{9 4}, \frac{1 5 6}{9 4}, \frac{- 1 8 2}{9 4} >

Explanation: Let

Finding the distance, midpoint, slope, equation and the x y-intercepts of a line passing between the two points p1 (-3,1) and p2 (-1,4)The distance (d) between two points (x1,y1) and (x2,y2) is given ...

What is the slope of the line passing through the following points:

(- 6, 7), (- 5, 2)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-6-7-5-2

- 5

Explanation: Slope is defined as the change in

y

divided by the change in

x

between two points.

(XXX) slope = \frac{Δ y}{Δ x}

What is the slope of the line passing through the following points:

(- 6, 7), (0, - 4)

https://socratic.org/questions/what-is-the-slope-of-the-line-passing-through-the-following-points-6-7-0-4

m = - \frac{1 1}{6}

Explanation: The formula for slope is

m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}}

For the coordinate points

(- 6, 7) and (0, - 4)
