a

Step-by-step explanation:

can i have brainliest

Step-by-step explanation:

Using the Law of Sines

sin30/a=sin45/8

a=8sin30/sin45

a=8(1/2)^(1/2)

a=(64/2)^(1/2)

a=(32)^(1/2)

a=4(2)^(1/2)

so the first answer is correct

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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.
