Answer: 6/50
Step-by-step explanation:
15x²+16x+4 =0 (ax² +bx +c=0)
Δ = b²-4ac =256 - 4×15×4 =16
x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
Where did you get this question?
average Speed and velocity = distance / time = 160 / 2 = 80 miles per hour.
Answer:
8%
Step-by-step explanation:
You multiply 4 times .08 which =32, so 8% of 4.00 =32 cents.
