Answer:
4. 4.81×10^13
Step-by-step explanation:
There are 13 digits after the 4 so it is
4.81 * 10^13.
a1 = 54
a2 = (1/3)a1 = (1/3) * 54 = 18
a3 = (1/3)a2 = (1/3) * (1/3)a1 = 18/3 = 6
etc.
Answer:
6 minutes per kilometer
Step-by-step explanation:
[] First, let's get one unit. I will be using minutes;
2 hours 6 minutes = 120 mintues + 6 mintues = 126 mintues
[] There are about 21 kilometers in a half-marathon;
126 minutes / 21 kilometers = 6 minutes per kilometer
Have a nice day!

Answer:
The system has no solutions.
Step-by-step explanation:
Let's write it in a more traditional form
Try staring at it for a bit, and then realize what you are being asked: find two numbers whose difference is - at the same time, 7, and -7/6. That's impossible.
Same result you get by elimination. Multiply the first by 6 and either add or subtract - your choice the second. In either case you will get 0 = 35 or 0=49, which are obviously absurd
Answer
63.2 degrees
Step-by-step explanation:
Using law of cosines: 19^2=8^2+14^2-2(8)(14) cos (x)
361=64+196-224 cos(x)
361=260-224cos(x)
101=224cos(x)
divide both sides by 224, which gets you (rounded to 4th decimal place) 0.4509. do inverse cos which gets you 63.2
