Answer:
t=10 s
Step-by-step explanation:
v=u+gt
108=10+9.8t
108-10=9.8t
9.8t=98

Setting d = 0 gives the points where she is at the surface.
therefore 0= 0.1t^2 - 3.5t + 6
apply the quadratic formula to get t = (3.5+- √12.25-4*0.1*6)/0.2
t = (3.5 <span>3.1384709653)/0.2
t= </span>1.80764517352 and <span>33.1923548265
</span>subtract the 2 to get the time difference between entry and exit you get
Δt = <span>31.384709653 seconds

That's as long as I haven't made a mistake :D
Answer:
8th term is 3980.
Step-by-step explanation:
0 12 72 240 598 1250 2322
Differences in successive terms
are:
12 60 168 358 652 1072
48 108 190 294 420
60 82 104 126
22 22 22
So calculating the 8th term , working from the last line to the first:
126 + 22 = 148
148 + 420 = 568
1072 + 568 = 1658
Finally the 8th number = 2322 + 1658 = 3980
