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)

cosx=adj/hyp=12/13
then tanx=opp/adj=5/12
siny=3/5
tany=3/4
tan(x+y)=tanx+tany/1-tanxtany
=(5/12+3/4)/(1-(5/12)(3/4)
=(14/12)/(1-15/48)
=36/125+18/125+16/125
=70/125
=14/25
======================

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
=24/125+9/125+4/125
=47/125
3b)
Pr(atleast one failed)
=4/5*3/5*3/5+3/5*2/5*1/5+4/5*2/5*2/5
=101/125
======================

4)
(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
and 1
(3+2y)^5
=(3)^5+5(3)^4(2y) + 10(3)^3(2y)^2 + 10(3)^2(2y)^3 + 5(3)(2y)^4 +

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)
=2/5(4/25-9/5)
=2/5(-41/25)
=-82/125
11aii)
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

=>x^2+4x+3
=x^2+3x+x+3
=x(x+3)+1(x+3)
=(x+1)(x+3)
the remaining factors of f(x) are (x+1) and (x+3)
11biii)
Zero of f(x)
x-2=0,then x=2
x+1=0, then x=-1
x+3=0, then x=-3
Zeros of f(x) are 2,-1 and -3

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
=mg=30*10=300N
