Answer:
t = 2.11 seconds
Step-by-step explanation:
A toy rocket is launched from the top of a 48 foot hill. The rockets initial upward velocity is 32 feet per second and its height h at any given second t is modeled by the equation:
Let us assume that we need to find the time by it to reach the ground. It means h = 0
The above is a quadratic equation. The value of t is given by :
So, it will take 2.11 seconds to reach the ground.
Answer:
1: 11√3 - 7√6
2: 11√3 - 7√6
3: -9
4:12
Step-by-step explanation:
To add radicals they need to have the same radical part for the first one we have
7√3- 4√6 + √48 - √54
We can simplify the last two into 4√3 and 3√6
So we have 7√3 - 4√6 + 4√3 - 3√6
adding similar radicals we get
11√3 - 7√6
For the second one we have 11√3 - 7√6
There's nothing we can do from here so keep that as your answer
This one is quite easy -3√9
square root of 9 is 3
so we have -3*3 which is -9
next is
4√9
same deal as the one before
3*4=12
What does a standard deviation of 0 indicates 0.
Answer:
e
Step-by-step explanation:
The cube on the top, the one with the width of 4 is Cube 1.
The other one is Cube 2.
The length of the cube is 4, the width 2, and the height 5.
We know the length is 4 because we can look at the side, where both measurements 6 ft and 3 ft can be found.
We know that the height is 5 because for Cube 2, the height is 3. The total height is 8, so we subtract 3 from 8. We get our difference of 5.
V = l x w x h
V = (4)(2)(5)
V = (8)(5)
V = 40.
Cube 2 has a length is 6, the width 2, and the height 3.
V = l x w x h
V = (6)(2)(3)
V = (12)(3)
V = 36
We add the volumes of both cubes.
40 + 36 = 76
probs not right but hope it helped :)
We need to count the number of games that score 15, 16, 17 and 18
Score 15 = 3 games
Score 16 = 2 games
Score 17 = 5 games
Score 18 = 3 games
Total = 13 games
