Answer: choice 1 and 6
Step-by-step explanation:
just plug in 9 for every X making sure they equal each other.
Answer:
a)
v=<400, 450+3t, 600-9.81t> m/s
r=<400t, 450t+3
/2, 15+600t-9.81
/2> m/s
b) attach file
c) t=122.324s
d) z=18369.9854 m
Step-by-step explanation:
a)
The equation for velocity of each component is v=
+at, in this case the x-axis component has acceleration 0
, the y-axis component has acceleration 3
and the z-axis component has -g
, where g=9.81
.
The equation for position of each component is x=
+
t+a
/2,
with <
,
,
>=<0,0,15>.
c) This time is t when z=0, with positive sign.
d)Solving the equation
=
+ 2*a*(z-
) for z, with
=0.
Answer:
The mean is: 10.666667
The medium is: is between 15
Step-by-step explanation:
There is no exact rule for lines of best fit. However, in general, there should be roughly the same amount above as below. So, if we are following this rule, there should be about 4 below as well.
