Use the discriminant and select whether the roots of 4x 2 - 3x + 3 = 0 are real or imaginary.

roots are imaginary

Step-by-step explanation:

Formula to find discriminant is

Given equation is in the form of ax^2+bx+c=0

a=4, b=-3, c=3

Plug in all the values in the discriminant formula

When discriminant >0, the roots are real

when discriminant <0 then roots are imaginary

we got discriminant =-39 that is less than 0, so roots are imaginary

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

in my opinion , its hazel
