Answer:
Step-by-step explanation:
Choose the equation that represents the solutions of 0 = 0.25x4 - 8x.
0.25+ (0.25)2 – (4)(1)(-8)
2(1)
X=
-0.25 + (0.25)2 – (4)(1)(-8)
x=
2(1)
8+ (-8)2 – (4)(0.25)(0)
X =
2(0.25)
-8+ (-8)2 – (4)(0.2530
X =
2(0.25)
Speed=distance / time; ⇒distance=speed * time
Distance traveled by Ricardo
Distance (Ricardo)= (3 ft / s) * 15s+3 ft/s * time=45 ft+3 ft/s*t=45+3t
Distance traveled by John:
Distance(John)=(4 ft/s) * time=4t
Distance traveled by Ricardo=Distance traveled by John
3t+45=4t
Answer: D. 3t+45=4t
