3.	If the points A(a -11) B(5,b) C(2,15) and D(1,1)are the vertices of a parellogram ABCD.find the value of a and b
Answer» Step-by-step EXPLANATION: Given:- The points A(a -11) B(5,b) C(2,15) and D(1,1)are the vertices of a parellogram ABCD. To find:- Find the value of 'a' and 'b' ? Solution:- Given points are A(a -11) B(5,b) C(2,15) and D(1,1) Given that They are the vertices of a Parallelogram. We know that The DIAGONALS of a Parallelogram are BISECTING to each other. AC and BD are the diagonals =>Mid point of AC = Mid point of BD Mid point of AC:- Let (x1, y1)=A(a,-11)=>x1 = a and y1 = -11 (x2, y2)=C(2,15)=>x2 = 2 and y2 = 15 We know that The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2] Mid point of AC = [(a+2)/2 , (-11+15)/2] =>((a+2)/2 ,4/2) Mid point of AC =((a+b)/2 ,2)---------(1) Mid point of BD :- Let (x1, y1)=B(5,b)=>x1 = 5 and y1 = b (x2, y2)=D(1,1)=>x2 = 1 and y2 = 1 We know that The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2] Mid point of BD =[(5+1)/2 ,(b+1)/2] =>(6/2,(b+1)/2)) Mid point of BD = (3, (b+1)/2)--------(2) From (1) and (2) =>(1)=(2) =>Mid point of AC = Mid point of BD =>((a+b)/2 ,2) = (3, (b+1)/2) On comparing both sides, then =>(a+b)/2 = 3 and 2=(b+1)/2 =>a+b=2×3 =>a+b=6---------(3) and 2=(b+1)/2 =>b+1 = 2×2 =>b+1=4 =>b = 4-1 =>b = 3 On Substituting the value of b in (3) then =>a+3 = 6 =>a = 6-3 =>a = 3 Therefore, a= 3 and b= 3 Answer:- The value of a = 3 The value of b = 3 Used formulae:- The diagonals of a Parallelogram are bisecting to each other. The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2]

3.

If the points A(a -11) B(5,b) C(2,15) and D(1,1)are the vertices of a parellogram ABCD.find the value of a and b

Answer»

Step-by-step EXPLANATION:

Given:-

The points A(a -11) B(5,b) C(2,15) and D(1,1)are the vertices of a parellogram ABCD.

To find:-

Find the value of 'a' and 'b' ?

Solution:-

Given points are A(a -11) B(5,b) C(2,15) and D(1,1)

Given that They are the vertices of a Parallelogram.

We know that

The DIAGONALS of a Parallelogram are BISECTING to each other.

AC and BD are the diagonals

=>Mid point of AC = Mid point of BD

Mid point of AC:-

Let (x1, y1)=A(a,-11)=>x1 = a and y1 = -11

(x2, y2)=C(2,15)=>x2 = 2 and y2 = 15

We know that

The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2]

Mid point of AC = [(a+2)/2 , (-11+15)/2]

=>((a+2)/2 ,4/2)

Mid point of AC =((a+b)/2 ,2)---------(1)

Mid point of BD :-

Let (x1, y1)=B(5,b)=>x1 = 5 and y1 = b

(x2, y2)=D(1,1)=>x2 = 1 and y2 = 1

We know that

The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2]

Mid point of BD =[(5+1)/2 ,(b+1)/2]

=>(6/2,(b+1)/2))

Mid point of BD = (3, (b+1)/2)--------(2)

From (1) and (2)

=>(1)=(2)

=>Mid point of AC = Mid point of BD

=>((a+b)/2 ,2) = (3, (b+1)/2)

On comparing both sides, then

=>(a+b)/2 = 3 and 2=(b+1)/2

=>a+b=2×3

=>a+b=6---------(3)

and

2=(b+1)/2

=>b+1 = 2×2

=>b+1=4

=>b = 4-1

=>b = 3

On Substituting the value of b in (3) then

=>a+3 = 6

=>a = 6-3

=>a = 3

Therefore, a= 3 and b= 3

Answer:-

The value of a = 3

The value of b = 3

Used formulae:-

The diagonals of a Parallelogram are bisecting to each other.

The mid point of a line joining the points (x1 ,y1) and (x2, y2) is M(x,y)=[(x1+x2)/2 ,(y1+y2)/2]

Answer»

☆ ΛПƧЩΣЯ ☆

Consider an object moving with initial velocity u, is uniformly ACCELERATED with an acceleration 'a' for time 't', finally REACHES velocity 'v' after covering displacement 's'.

From FIGURE OA=OC=u. BC=v

OC=AD=t. BD=v-u

The displacement of an object can be calculated by finding the area under velocity time graph.

Area under velocity time graph =Area of trapezium OABC

✈ Displacement =Area of rectangle OA DC+Area of triangle ABCD.

Displacement =length +breadth+1/2×base×height

S=OA ×OC+1/2 AD×BD

=ut + 1/2 t (v-u)

=ut + 1/2 t ×a t

Find the ratio of speed of a cycle 5 km per hour to the speed of a scooter 45 km per hour

Answer»

Answer:

a) Speed of a cycle 15 km per HOUR to the speed of scooter 30 km per hour.

(b) 50 m to 10 km

(C) 50 PAISE to Rs.5

Solution:

(a) Speed of cycle = 15 km/hr

Speed of scooter = 30 km/hr

Hence ratio of speed of cycle to that of scooter = 15 : 30 = \frac{15}{30}=\frac{1}{2}=1:2

(ii) \BECAUSE1\ km\ =\ 1000\ m∵1 km = 1000 m

\therefore10\ km=10\times1000=10000m∴10 km=10×1000=10000m

\therefore Ratio=\frac{5m}{10000m}=\frac{1}{2000}=1:2000∴Ratio=
