1 yard = 3 feet so 1 yard by 1 yard = 3 x 3 = 9 square feet.. This means that 9 squares that are 3 feet by 3 feet will fit into a square that is 1 yard by 1 yard.
Answer:
net force is the force used to push or pull the box
Step-by-step explanation:
for example-
==> 15N BOX 12N <==
15-12=3
3N
if they point the same way add if they point the opposite subtract
The information given is sufficient for this proof .
Slope of a line passing through x1 ,y1) and ( x2,y2) is given by the formula :
M = ( y2 - y1)/ ( x2-x1)
________________________________
Let us start finding the slope of line PQ
the given points are ( a,b) and ( c,d)
using the slope formula we get :
slope of line PQ = m= ( d-b) /( c-a)
Let us now try finidng slope of the another line P'Q'
It is passing through ( -b ,a) and (-d,c)
using the formula we get slope of P'Q' = m' = ( c-a) /( -d - -b)
m'= ( c-a) /( -d+b)
m'= ( c-a) / -( b-d Let us find the product of m and m' :
( d-b ) * ( c-a)
----------- ------------ = -1
(c-a) - ( b-d)
Because we got product of m and m' = -1 hence proved product of perpendicular lines are negative reciprocal of each other .
