Answer as much as questions as u can : GROUP A

A) The perimeter of a triangle = a + b + c. Find the perimeter of these traingles.

1) a = 5cm

B) If x = 3,y = 2 and z = -1, evaluate the following expression.

1)5xy

C) The perimeter of a square = 4l and area = l. Find the perimeter and the area of these squares.

1) l = 3cm

D) The perimeter of a rectangle = 2 (a + b). Find the perimeter and the area of these rectangles.

1) l = 5cm

GROUP B

A) If n=2 and y=3, Find the value of :-

1) x^y
2) y^x
3) x^y^2
4) y^x^2

B) If a=5 and b=2, find the value of :-

1) a^b
2) b^a
3) 2^a
4) 3^b

(u can attempt any questions u like no pressure)

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
