Answer:
6.3
Step-by-step explanation:
The rocket hits the ground at the same speed it left, only the velocity is downward, rather than upward. That is, the change in velocity is from +100 ft/s to -100 ft/s, a total change of 200 ft/s. The change in velocity is brought about by the acceleration due to gravity, 32 ft/s/s. The time required for the observed change in velocity is ...
(200 ft/s)/(32 ft/s²) = 6.25 s
Rounded to tenths, it takes the rocket 6.3 seconds to hit the ground.
_____
The equation for the ballistic motion of the rocket is ...
h(t) = -1/2·gt² +v0·t
where g is 32 ft/s² and v0 is 100 ft/s. A graph of this equation shows the rocket hits the ground at 6.25 seconds, as above.
Answer:
Step-by-step explanation:
given that Suppose that $2n$ tennis players compete in a round-robin tournament. Every player has exactly one match with every other player during $2n-1$ consecutive days.
this is going to be proved by contradiction
- Let there be a winning player each day where same players wins twice, let n = 3
- there are 6 tennis players and match occurs for 5days
- from hall's theorem, let set n days where less than n players wining a day
- let on player be loser which loses every single day in n days
- so, players loose to n different players in n days
- if he looses to n players then , n players are winner
- but, we stated less than n players are winners in n days which is contradiction.
- so,
- we can choose a winning players each day without selecting the same players twice.
We are given order pairs (x,y) as (Number of steps, Number of feet).
On the given graph, order pairs are :
(2,6)
(4,12)
(6,18)
(8,24)
(10,30).
We need to find the the number of feet Jorge walks in 3 steps.
<em>Rate of number of feet per number of step is (12-6)/(4-2) = 6/2 = 3.</em>
In order to find the number of feet Jorge walks in 3 steps, we need to multiply 3 by rate.
Therefore, 3 × 3 = 9.
<h3>Therefore, (3,9) ordered pair represents the number of feet Jorge walks in 3 steps.</h3>
Answer:3
Step-by-step explanation: the reason why it's 3 is because 54 divided by 9 is 6 and 6 divided by 2 is 3
