If the zeros of a quadratic function are 3 and 8, what are the factors of the function?
o a. (x+8) and (x - 3)
ob. (x - 8) and (x+3)
o c. (x+8) and (x + 3)
d. (x-8) and (x - 3)

Option D

If the zeros of a quadratic function are 3 and 8 then the factors of function are x - 8 and x - 3

Solution:

Given that zeros of quadratic functions are 3 and 8.

Need to determine the factors of quadratic function

Lets function be f(x) that is variable is x.

Zeros of quadratic functions are 3 and 4 means,

x = 3, x = 8 are solutions of f(x)

When x =3 ,( x – 3 )  = 0

When x = 8 , ( x – 8 ) = 0  

Hence we can say that ( x – 3 )  and ( x – 8 ) are factors of polynomial f(x).hence correct option is D that ( x – 3 )  and ( x – 8 )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
