Answer:
(-9.15)
Step-by-step explanation:
We are given these following vectors:
u = (2,4), v = (-1,-1), w = (7,-2)
What is the vector for 3u + v- 2w in component form?
3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)
The answer is (-9,15).
Answer: New York population is bigger by 580,000 ,which can be written in standard form as 5.8 x
Step-by-step explanation:
2 x can be written in ordinary number as 20,000
6 x can be written in ordinary number as 600,000
With this , it is clear that New York has a larger population.
The difference in their population will be
600,000 - 20,000 = 580,000
Answer:
20 minutes
Step-by-step explanation:
Manila walked home in 30 minutes. She walks 4 miles an hour. Since 30 minutes is half an hour then its half the distance of the rate. 4/2 = 2 miles. This means home is 2 miles away.
Since her sister runs 6 miles an hour, the time it took her will be for only 2 miles. So 6 miles divided into 3 is 2. An hour divided by 3 = 20 minutes. This means her sister travels home 2 miles in 20 minutes.
