1a)
A=(2 -1)(1 3)
|A|=(2*3–1)
|A|=6+1
|A|=7
since the determinant of A is not 0 the A is not non singular
matrix
To find A^-1
A^-1=(3 1)(-1 2)
then 1/7(3 1)(-1 2)
A^-1=(3/7 1/7)(-1/7 2/7)

3a)
Pr(A passed)=4/5,pr(A failed)=1/5
Pr(B passed)=3/5,Pr(B failed)=2/5
Pr(C passed)-2/5,Pr(C failed)=3/5
Pr(atleast one passed)
=4/5*2/5*3/5+3/5*1/5*3/5+2/5*1/5*2/5

(3+2y)^5 with (a+b)^5 shows
a=3,b=2y
Using pascals triangle the coefficient of (a+b)^5 are 1,5,10,10,5

5x^2-2x+3=0
Divide both sides by 5
x^2-2/5x+3/5=0–eq1
Compare eq1 above with
x^2-(alpha+Beta)x+alphabeta=o
alpha+beta=2/5
alphabeta=3/5
11ai)
alpha^3+beta^3 = (alpha+beta) (alpha+beta)^2 – 3alphabeta
=2/5(2/5)^2-3(3/5)

Sum of alpha +1/beta and beta+1/alpha
=(alphabeta+1)/beta + (alpha beta + 1)/alpha
=alphabeta^2+alpha^2beta+beta/alphabeta
=alphabeta(alpha+beta) + (alpha+beta)/alphabeta
product root
(alpha +1/beta)(beta+1/alpha)
=alpha(beta+1/alpha)=1/beta(beta+1/alpha)
=alphabeta+1+1+1q/alphabeta
sum=alphabeta(alpha+beta) + (alpha+beta)/alphabeta
=3/5(2/5)+(2/5)
=6/25+2/5
=(6+10)/25
=16/25
Product alphabeta+2+1/alphabeta
=3/5+2+1/(3/5)
=3/5+2/1+5/3
=64/15.
Recall
x^2-(alpha+beta)+alphabeta=0
x^2-16/25x+64/15=0

Make A the reference point
Pw=2.5m,
AM=(2.5-0.8)m
=1.7m g=10m/s
AB=3.2m,PA=0.8m
Convert 30kg to weight
