Answer:
7.2/3 ± (isqrt2)/3
8.2±i
9.-0.4±0.2
10.1/3±1/3sqrt19
Step-by-step explanation:
7. a =3, b=-4, c=2
plugging in to the quadratic formula
(2 ± isqrt2)/3
8.a=1,b=-4.c=5
plugging in to the quadratic formula
2±i
9.a=5,b=4,c=2
plugging in to the quadratic formula
-0.4±0.2
10.a=-3,b=2,c=6
plugging in to the quadratic formula
1/3±1/3sqrt19
3/10 of an hour is 6x3=18 mins
To get to one hour we do 3/10 x 10 / 3
So we 1/6 x 10 / 3 = 10/6 / 3 =5/3 / 3=5/9
Answer:
x = 360 - 49 - 136 - 69 = 106°
