Question

plz help me to solve this ​

Answer 1

Solution

(1)

the radical is =√49

(2)

p(y)=y²-y+1

therefore...

p(3/2)=(3/2)²-(3/2)+1

=(9/4)-(3/2)+1

=(9-6+4)/4

=7/4

(3)

the point (-1,4)lies on the 2nd quadrant.

(4)

5x-4y=k

=>5(-4)-4(-5)=k

=>-20+20=k

=>k=0

(5)let the first is X

so the other is 2x-9°

now..

X+2x-9°=180°

3x=189°

=>X=189°/3=63°

option (I)63°

(6)

where is the figure

(7)

zero of the polynomial...means p(X)=0

2x-a²=0

=>X=a²/2

(8)

a linear polynomial has only

(iv)one and only one zero

(9)

rational+irrational=irrational

(10)
