Answer:
[-8,8]
Step-by-step explanation:
Polygons are similar? Well there is no picture provided, so I have no idea what you're talking about. But I think you might be asking if in general all polygons are similar, and if that's the case, they are not. Similar means they are similar in at least one aspect, and all polygons are different from each other, only adding one line for each bigger polygon. So I don't know if this helped you, but I tried anyways.
B is the correct answer choice I know it
The speed of the driver is 200km/hr.
<h3>How to calculate the speed?</h3>
The information is incomplete and an overview will be given since the complete information wasn't found online.
It should be noted that speed is calculated as:
= Distance / Time
Let distance = 2000km
Let time = 10 hours.
Speed = Distance/Time
Speed = 2000/10
Speed = 200km/hr

Answer:
The vector will change in direction and decrease in magnitude
Step-by-step explanation:
Given:
vector multiplication by -π/4
-π/4= -0.785
Due to the negative sign "-", the, vector will change/reverse its direction.
And as of the magnitude, 0.785<1 hence the magnitude of vector will be decreased by this factor !
