(b) Use the right-hand rule to decide whether the components of a × b are positive, negative, or 0.

Gekata [30.6K]

(a)

Given:

$\vec{a}$ is in xy plane and $\vec{b}$ is in the direction of k.

|a|=6 units, |b|=3 and θ = 90°

|a × b| = |a| × |b| sinθ

= |a| × |b| sin90°

= 6 × 3 × 1

|a × b| = 18

(b)

Let $\vec{c}=\vec{a} \times \vec{b}$

$\vec{c}$ is perpendicular to both $\vec{a} \text { and } \vec{b}$ .

In this case,

x-component of $\vec{a} \times \vec{b}$ is positive.

y-component of $\vec{a} \times \vec{b}$ is negative.

z-component of $\vec{a} \times \vec{b}$ is zero.

How is the system graphed, and how are the solutions determined?

lana [24]

Answer:

$\text{The solut}\imaginaryI\text{on for the system }\imaginaryI\text{s}\operatorname{\lparen}2,1\operatorname{\rparen}$

Step-by-step explanation:

The solution of the given functions would be the point of intersection of the two functions, then by graphing linear functions.

$\begin{gathered} y=mx+b \\ where, \\ m=\text{ slope} \\ b=\text{ y-intercept} \end{gathered}$

For the given function:

$\begin{gathered} y=-\frac{1}{2}x+2 \\ y=2x-3 \end{gathered}$ $\text{ The solution for the system is \lparen2,1\rparen}$

Answer: B

Step-by-step explanation: The question is asking for the point greatly different from all the rest, the outlier. Point B is far away from the grouping of all the other points, making it the outlier.
