Use pascal's triangle to find (8 4) I don't get how to do this can some one help me please!!
1 answer:
Pull out your reference sheet that has the Pascal's Triangle.
Step 1) Locate the row that starts with 1, 8, ... If this row isn't shown, then you'll need to find a bigger Pascal's Triangle.
Step 2) Count out exactly five spaces starting at the first value 1. Why five? Because we start at 0 instead of starting at 1. The first value in the row represents
while the second value in that row represents 
and the third value represents 
and so on. So the value 
is in the fifth slot from the left.
You should land on the value 70, which is the final answer

Answer:
The velocities after 739 s of firing of each engine would be 6642.81 m/s in the x direction and 5306.02 in the y direction
Step-by-step explanation:
- For a constant acceleration:
, where
is the final velocity in a direction after the acceleration is applied,
is the initial velocity in that direction before the acceleration is applied, a is the acceleration applied in such direction, and t is the amount of time during where that acceleration was applied.
- <em>Then for the x direction</em> it is known that the initial velocity is
5320 m/s, the acceleration (the applied by the engine) in x direction is
1.79 m/s2 and, the time during the acceleration was applied (the time during the engines were fired) of the is 739 s. Then:
- In the same fashion, <em>for the y direction</em>, the initial velocity is
0 m/s, the acceleration in y direction is
7.18 m/s2, and the time is the same that in the x direction, 739 s, then for the final velocity in the y direction:
