Answer:
<h2>After two seconds, the ball reached 9 units up.</h2>
Step-by-step explanation:
The given function is
The given function models the path of the ball.
The maxium height the ball reached is given by the vertex of this function, which has coordinates 
, where 
and 
.
From the equation, we know that 
, 
and 
. Replacing these values, we have
Where 
determines the height and 
the time when the maximum height was reached by the ball.
The maximum height is 9 units.
Therefore, after two seconds, the ball reached 9 units up.
3/7 + 2/3
3/7 x 3/3 = 9/21
2/3 x 7/7 = 14/21
9/21 + 14/21 = 23/21 = 1 2/21
Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
There are at least 3 houses on a street if at least two of them have addresses that are consecutive integers.
So.. Liliana used 4 crystals to race 14 zombie soldiers.
14 / 4 = 3.5. She can race 3.5 zombie soldiers if she uses 1 crystal. So, all you need to do it multiply 3.5 by 10 and you end up with 35.
So, Liliana is able to race 35 zombie soldiers with 10 power crystals.
Glad I could help!
