Answer:
(1)
Multiplying by 3 both sides of the equality you get that
3u is in the Span of the vectors .
(2)
That's not true, consider the following counter example.
is a linear combination of but is NOT a linear combination of
Step-by-step explanation:
(1)
As the hint indicates, you know that
Then, if you multiply both sides of the equality by 3, you get that
And that's it. 3u is in the Span of the vectors
(2)
That's not true, consider the following counter example.
is a linear combination of but is NOT a linear combination of
The formula for speed is the total distance traveled over time. We shall calculate the 2 speeds individually- before and after lunch. Afterwhich, we shall add them together and divide by 2 to get the average.
Before lunch s = 132 mi / 3 hr = 44 mi/hr
After lunch s = 240 mi / 5 hr = 48 mi/hr
Ave s= 48 + 44 / 2
Ave s= 46 mi/hr
Therefore the correct answer is A.
