Answer:
C. 0
Step-by-step explanation:
–4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac if >0 we have 2 real solutions
=0 we have 1 real solutions
<0 we have 2 imaginary solutions
a = -4, b =3 c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions
recall from the previous posting, 2⁸ = 256, so that's one way to represent it.
now, another way hmmm
Answer:
(0,5) (0,-5)
Step-by-step explanation:
Answer:
<em><u>122 miles per hour</u></em><em><u>.</u></em><em><u> </u></em>
Step-by-step explanation:
Time:108 min ÷60 =1.8 hours
Speed = distance /time = 219/1.8 =122 miles per hour.
Hope this helps..
