(1 point) let a=⟨−4,−3,2⟩a=⟨−4,−3,2⟩. find a unit vector in the same direction as aa.

sergij07 [2.7K]

A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2) [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).

So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).

Solve |3x - 4| = 6 a) {-10/3,10/3} b) {-2/3,10/3} c) {-2/3,2/3}

ella [17]

To dea with absolute values you need to apply the definition of absloute value OR get rid of it by squaring both sides of the equality.
Let's try it by using the definition of the absolute value:
$\left | \alpha \right | \left \{ {{ \alpha , \alpha \geq 0} \atop {- \alpha , \alpha \ \textless \ 0}} \right.$

So, having that in mind, we must split the initial equation into two.
$\left | 3x-4 \right | \left \{ {{(3x-4), x \geq 4/3} \atop {-(3x-4),x\ \textless \ 4/3}} \right.$
Then, we end up with two equations:
$3x-4=6 \\ -(3x-4)=6$
Both yield the solutions:
$x=10/3 \\ x= -2/3$

So your answer would be the second option
