Answer:
A 5cm
Step-by-step explanation:
The others answers would be either too big or too small to fit
Well, if 1 mile = 1.6 kilometers and he's traveling at 18mph, then do 18 x 1.6 which = 28.8.
So, this is his current speed in kph
3 x 28.8 = 86.4
They will have traveled 86.4 kilometers
(I haven't worked with this kind of math in a while so correct me if I'm wrong!)
The list contains three points that lie on the graph of the reflection is (-49, 7), (-18, 9), (-1, 1).
<h3>What is graph reflection?</h3>
The graph of any function when mirrored on the same plane.
Given the graph of f(x)=√x is reflected over the y-axis. Use the graphing calculator to graph this reflection.
The points which can satisfy the reflection of the graph is (-49, 7), (-18, 9), (-1, 1).
Thus, the fourth option is correct.

(a)
Given:
is in xy plane and 
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 
is perpendicular to both 
.
In this case,
x-component of 
is positive.
y-component of is negative.
z-component of is zero.
