Answer:
{ 9/2 , square root of 100, 5.123}
Step-by-step explanation:
Here we want to find the possibles magnitudes of the sum of two vectors.
Sadly, the options are not given, so I will give you the range of all the possible magnitudes of the sum of these two vectors.
We will find that any magnitude in the range: 58cm ≤ M ≤ 100cm <u>is a possible magnitude or the resultant vector.</u>
<em>How we can find that range?</em>
What we need to do is find the <u>maximum and minimum.</u>
The minimum is the case where the two <u>displacements are in opposite directions</u>, in that case, the magnitude of the sum will be:
79cm - 21cm = 58cm
The maximum is when<u> both displacements are in the same direction</u>, thus we must add the displacements, then we have:
79cm + 21cm = 100cm
Thus, any magnitude in the range:
58cm ≤ M ≤ 100cm
Is a <u>possible magnitude for the resultant vector.</u>

Answer:
The sum of a and b is 12.
Step-by-step explanation:
Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect - considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.
Distance between points ( 0, 1 ) and ( 2, 5 )
=
=
=
= =
Distance between points ( 2, 5 ) and ( 7, 0 )
=
=
=
= =
And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly as well. Therefore, you can say that the perimeter of this triangle is = . Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.
