Answer:
The measure of the fourth side is 
.
Step-by-step explanation:
Given as :
The Perimeter of rectangular store = ( 10 + 
) inches
The measure of three sides of rectangle = ( 8 + 
) inches
So, The measure of three sides = length + breadth + length
I,.e 2 L + B = ( 8 + ) inches .....1
∵ perimeter = ( 10 + ) inches
So , 2 L + 2 B = ( 10 + ) inches
Or, 2 L + B + B = ( 10 + ) inches
Or, ( 8 + ) + B = ( 10 + )
or, B = ( 10 + ) - ( 8 + )
Or, B = 10 - 8 + ( ) -
or, B = 2 + 
or, B = 2 + 
∴ B = 
=
Hence The measure of the fourth side is . Answer
Answer:
(4, -8)
Step-by-step explanation:
The components of a vector are found by subtracting the tail from the head.
__
Head - Tail = (1, -6) -(-3, 2) = (1 -(-3), -6 -2) = (4, -8)
⇒ The component form is (4, -8), or maybe 4<em>i</em> -8<em>j</em>.
_____
<em>Additional comment</em>
There are many ways that the components of vectors can be described. The particular format you are expected to use will likely be found in your curriculum materials.
Answer:
In the given figure the point on segment PQ is twice as from P as from Q is. What is the point? Ans is (2,1).
Step-by-step explanation:
There is really no need to use any quadratics or roots.
( Consider the same problem on the plain number line first. )
How do you find the number between 2 and 5 which is twice as far from 2 as from 5?
You take their difference, which is 3. Now splitting this distance by ratio 2:1 means the first distance is two thirds, the second is one third, so we get
4=2+23(5−2)
It works completely the same with geometric points (using vector operations), just linear interpolation: Call the result R, then
R=P+23(Q−P)
so in your case we get
R=(0,−1)+23(3,3)=(2,1)
Why does this work for 2D-distances as well, even if there seem to be roots involved? Because vector length behaves linearly after all! (meaning |t⋅a⃗ |=t|a⃗ | for any positive scalar t)
Edit: We'll try to divide a distance s into parts a and b such that a is twice as long as b. So it's a=2b and we get
s=a+b=2b+b=3b
⇔b=13s⇒a=23s
