Answer:
combined velocity of the system = 0.033 m/s.
Step-by-step explanation:
taking the bullet and block as single system since there is no external force involved momentum is conserved .
initial momentum of the bullet = mv
where m is the mass of bullet and v is velocity of bullet.
and initial momentum of block = 0 since its velocity is 0.
therefore initial momentum of the system = mv
= 0.005×40
= 0.2
when the bullet stick of together with the block let the combined velocity of the system be V
therefore applying conservation of momentum
mv = (M+m)V
0.2=(6+0.005)V
therefore V = 0.033 m/s
Answer:
(E) 9
Step-by-step explanation:
I found what numbers worked in all three cases. I found that when a = 4 b = 5 c = 0, all of the equations were satisfied.
Equation 1 4 + 5 = 9
Equation 2 4 + 0 = 4
Equation 3 5 + 0 = 5
Also, a + b+ c or 4 + 5 + 0 = 9

I would do it in Buhh I'm working so add all of them(16,18,20) together 6 times then add another 16 and 18 and you will get your answer.
The answer is 12.5% this is the correct answer
Answer is -7
=============================================
Work Shown:
s_n = a_1*(1-r^n)/(1-r)
s_6 = a_1*(1-r^6)/(1-r)
s_6 = x*(1-(-3)^6)/(1-(-3))
s_6 = x*(1-729)/(1+3)
s_6 = x*(-728)/4
s_6 = x*(-182)
s_6 = -182x
-182x = s_6
-182x = 1274
x = 1274/(-182)
x = -7 is the first term of the geometric sequence
------------
Extra info:
The first six terms of this geometric sequence is
-7, 21, -63, 189, -567, 1701
those six terms add to
-7+21+(-63)+189+(-567)+1701 = 1274
which verifies we have the right answer.
