-16t²=-40
t²=10÷4
t=±√10÷4
t=±√10÷2
t=3.16÷2
t=1.58 seconds
t=1.6 seconds (Approximately)

<span>It is estimated that the city of Houston, Texas, will double in size every 35 years:
</span>P=Po(2)^(t/35)
<span>If the population is currently 2.4 million people:
Po=2.4 millions
</span><span>How many people will there be in 20 years?
t=20 years, P=?
P=(2.4 millions)(2)^(t/35)
P=(2.4 millions)(2)^(20/35)
P=(2.4 millions)(2)^(0.571428571)
P=(2.4 millions)(1.485994289)
P=3.566386294 millions
P=3.6 millions
