Review the Venn diagram. Which set of conditions is true? A. B 3 2. 1 7 8 5 9 10 4 6 O An B = 1, 3, 9, 10 A = 1, 3, 4, 8, 9, 10 B = 2, 5, 6, 7 AB=4,8 Au B = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 B = 2, 5, 6, 7 AnB=4, 8 A = 1, 3, 4, 8, 9, 10 B = 2, 4, 5, 6, 7, 8 O AU B = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 AnB = 1, 3, 4, 8, 9, 10 BnA = 2, 4, 5, 6, 7, 8​

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.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
