Answer:
Discriminant is 60
Step-by-step explanation:
the discriminant of 
To find discriminant , first we write the equation in the form of
Subtract 2 on both sides
a=3, b=6, c=-2
Formula for discriminant is 
Plug in the values
Discriminant is 60
Eight sides and angles too
Answer:
5040
Step-by-step explanation:
There are 7 possibilities for the first spot, 6 for the second, etc.
7*6*5*4*3*2*1=5040
1) y= - 2x² + 8x. It's a parabola open downward (a<0)
2) x - 2.23.y + 10.34 = 0 . Re-write it : y = (x/2.23) + (10.34/2.23), a linear equation.
To find the intersections between 1) & 2), let 1) = 2)
-2x² + 8x = (x/2.23) + (10.34/2.23)
-2x² + 8x - (x/2.23) - (10.34/2.23) =0 ; solve this quadratic for x values:
x' (that is A) = 0.772 & x" (that is B) = 3. (these are the values of x-intercept (parabola with line). To calculate the y-values, plug x' & x' in the equation:
for x' = 0.772, y = 0.34 → B(0.772 , 0.34)
for x" = 3, y = 0.016 → A(3 , 0.O16)
So B IS AT 0.34 Unit from the ground
