2 answers:
<u>Answer: </u>
Scientific notation of 50,000,000,000 is
<u>Solution: </u>
A scientific notation is representing the number such that it becomes between 1 to 10 and multiple of 10 raised to the appropriate power.
In our case, the number is 50,000,000,000.
We have to represent the given number 50,000,000,000 in scientific notation.
So we can write 50,000,000,000 as 5 x 10,000,000,000 =
Hence the scientific notation of 50,000,000,000 is

Answer:
Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately
Step-by-step explanation:
For this case first we need to calculate the dot product of the vectors, and after this if the dot product is not equal to 0 we can calculate the angle between the two vectors in order to see if there are parallel or not.
a=[1,2,-2], b=[4,0,-3,]
The dot product on this case is:
Since the dot product is not equal to zero then the two vectors are not orthogonal.
Now we can calculate the magnitude of each vector like this:
And finally we can calculate the angle between the vectors like this:
And the angle is given by:
If we replace we got:
Since the angle between the two vectors is not 180 or 0 degrees we can conclude that are not parallel
And the anfle is approximately
