Step-by-step explanation:
< means open circles
x-21<3 x≥21
-x+21<3 x<21
18<x<21 and 21≤x24
so the union of will be 18<x<24
Answer:
168.4953 (m/s)
Step-by-step explanation:
a(t)=x''(t)=(0.0951t⁴-0.101t³+0.837t²+3.87t-9.37)''= =4*3*0.951t²-3*2*0.101t+2*0.837 =11.412t²-0.606t+1.674.
a(3.85)=11.412*3.85²-0.606*3.85+1.674=168.4953
