Step-by-step explanation:
when h=7 ft
-16t²+49t+4=7
-16t²+49t-3=0
16t²-49t+3=0
16t^2-48t-t+3=0
16t(t-3)-1(t-3)=0
(t-3)(16t-1)=0
t=3,t=1/16
t=1/16 seconds is the time when it just started.
so reqd. time=3 seconds.
23-9= 14
14 divide by 2 = 7
so 7 baseball cards in a packet
x = negative 4 over 3 and x = 5
which is also B
