Solution :
Given initial velocity, v= 48 ft/s
Acceleration due to gravity, g =
a). Therefore the maximum height he can jump on Mars is
= 96 ft
b). Time he can stay in the air before hitting the ground is
= 8 seconds
c). Considering upward motion as positive direction.
v = u + at
We find the time taken to reach the maximum height by taking v = 0.
v = u + at
0 = 16 + (12) t
We know that,
Taking t = , we get
feet
Thus he can't reach to 100 ft as it is shown in the movie.
d). For any jump whose final landing position will be same of the take off level, the final velocity will be the initial velocity.
Therefore final velocity is = -16 ft/s
Answer:
No solution
Step-by-step explanation:
Note how "2x" shows up in both equations. This suggests doing a substitution to solve the system.
Focus first on the first equation. Solving 2x - y = 7 for 2x, we get:
2x = y + 7.
Next, we substitute y + 7 for 2x in the second equation:
y = (y + 7) + 3.
Simplifying this produces:
0 = 10
This is not true and can never be true. Thus, this system has no solution.
Answer:
so the answer must be 8
Step-by-step explanation:
4×-2(×+3)=8
Answer:
The 2 box-and-whisker plot is the correct one.
Step-by-step explanation:
The first step you need to do is write the numbers from least to greatest.
5, 7, 8, 10, 13, 14, 17, 17, 21. 5 and 21 will be the end points.
To make the box we need to find the median first. All you have to do is pick the middle number and it is 13. That just leaves box-and-whisker plots 2 and 3.
To find the first and third quartile, you need to take the other numbers from 13 to the left (10+8+7+5) and add them up then divide by 4 to get 7.5 and that is the first quartile.
To find the third quartile, you will go from 13 to the right (14+17+17+21) and divide by 4 to get 17.25.
This equals the 2nd box-and-whisker plot.
