Answer:
Step-by-step explanation:
<u>Line a</u>
- y = 5x - 6, it has slope of 5
<u>Line b</u>
<u>Rewrite in slope-intercept form to find its slope:</u>
- 5y = -x + 5
- y = -1/5x + 1
- It has slope of -1/5
Lines have different slopes: 5 and -1/5, therefore are not parallel
Explanation:
Mass of boy = 40 kg
Mass of box = 20 kg
Total mass = 60 kg
Initial potential energy = 0 (since height would be 0 initially)
Final potential energy = mgh
Taking g as 10 m/s²,
=> 60 × 10 × 15
= 9,000 J
So, work done = final potential energy - initial potential energy
= 9,000 J
Power = Work/Time
=> Power = 9000/25
=> Power = 360 J/s
or 360 watt.
Answer:
11x-y or 5x+y.
Step-by-step explanation: I hope this helps, I really don't know what the question means, since it not that specific.
The directions say round to the nearest tenth so use the 8.8 cm
