Formula for discriminant: d = b^2 - 4ac note that if d = 0 : real, equal/double root d < 1 : imaginary roots d > 1 : real, unequal roots 7x2 + 3x + 1 = 0 d = 3^2 - 4(7)(1) d = 9 - 28 d = -19 Thus, it's D. imaginary roots. Hope this helps~ :3

then either 10x-1=x-10 OR -10x +1 = x-10 9x = -9 or -11x = -11 x = -1 or x = +1 BUT, by definition |of anything| ≥0 so x-10≥0 x ≥ 10 So there is no solution

8 hours at 1000km/hr = 8000km. The circumference of the earth is roughly 40000km, so the trip was 1/5 of the way around, or 72°. The plane is now at 72-36.8 = 33.2° south. At that latitude, the east-west circumference is 33470 km 8000/33470 * 360° = 86° so, the plane is now at...

A plane leaves an airport X,20.6degree east and 36.8 degree north,and flies due south along the same longitude for 8hrs at the rate of 1000km/h to another airport Y,20.6 degree east and tita degree south.the plane then flies west to another airport Z for 8hrs at the same speed...
