The maximum time 1.75 second in case of not having the height:
1. change in ax²+bx+c form⇆ -16t²+56t-40=h
h=(8-8t)(2t-5)
h=16t-40-16t²+40t
h=-16t²+56t-40
2. t max=-b/(-2a)=-56/(-2×-16)=1.75 second
Answer:
LCM=72
Step-by-step explanation:
l.c.m by prime factorization
a)18,24
factor of 18=2*3*3
factor of 24=2*2*2*3
