What is interception and Apparent relative path in Relative velocity....How do we draw velocity diagrams for such questions???

 

[Saad Mughal]

Payments are made at the end of each payment interval for

ordinary
annuity
simple interest
all of these

Annuity.

 

[Saad Mughal]

If TWO LINEAR EQUATIONS IN TWO UNKNOWNS HAVE NO COMMON SOLUTION
THESE EQUATIONS ARE CALLED

CONSISENT
INCONSISENT
IDENTICAL
INDEPENDENT

Independant.

I'm not so good with Relative Velocity so I can't help you much.
However, Interception is the crossing of paths of two objects (e.g ships).
Relative apparent path is the path that appears to be taken by something as seen by an observer.

A Matrix A = (aij) is called row matrix if :

i=q and j =1
i = 1 and j > 1
i < 1 and j > 1
i < 1 and j = 1

 

[Saad Mughal]

A Matrix A = (aij) is called row matrix if :

i=q and j =1
i = 1 and j > 1
i < 1 and j > 1
i < 1 and j = 1

I think you've written the first part wrong. It should be i=1, j=1.

 

[sweetiepie]

I think you've written the first part wrong. It should be i=1, j=1.

Oh Bymistake Well Whats the answer?

 

[Saad Mughal]

Oh Bymistake Well Whats the answer?

It is the answer. i=1, j=1.

 

[sweetiepie]

how ?

 

[Saad Mughal]

how ?

i and j represent the number of rows and columns.
i = 1 means 1 row, j = 1 means 1 column.
Hence, A11 represents a Matrix of order 1*1 (row matrix).

what's row matrix?

 

[Saad Mughal]

what's row matrix?

I don't think it is in the syllabus. However, it is a matrix which has only 1 column.

 

[sweetiepie]

the formula for finding rate is :
A I*100 / p*r
B I*100 / P*t
C P*100 / I*t
D t*100 / P* I

t is used in replacement of N And r for i

 

[sweetiepie]

If R = Rs. 500 , n = 10 and I = 6%, then amount of ordinary annuity is :
Rs .4580.11
RS 8131.22
RS 6590.42
RS 5862.42

B is the answer.

 

[sweetiepie]

B is the answer.

how?

Rs .4580.11
RS 8131.22
RS 6590.42
RS 5862.42

Don't know about this. I haven't done this (in O'levels).

 

[Saad Mughal]

how?

Interest = PRT/100
I = P*R*t/100
I*100 = P*R*t
R = I*100/P*t
