B, the lowest because would you rather pay 12% daily or monthly
Answer:
4, 1, 6, 2, 3, 5
Step-by-step explanation:
When you have so many to do, it is convenient to let a calculator or spreadsheet do the math for you. The attached calculated the sums. Then the magnitudes needed to be calculated from those.
The numbers listed in the answer section are the order in which the resultant vectors appear in the ascending order list. That is, (u+2v-w)/6 appears first in the list.
_____
Each resultant is found by adding the given vectors with the given coefficients. For example, consider the first one on the list:
... -1/2u +5v = (-1/2)(9, -2) + 5(-1, 7)
... = (-9/2 -5, +1 +35) = (-19/2, 36)
Then the magnitude of it is found by adding the components according to the Pythagorean theorem. For the resultant just computed, the magnitude is ...
... √((-19/2)² +36²) = √(90.25 +1296) = √1386.25 ≈ 37.23
_____
In the attached, matrix multiplication is used to compute all 6 resultants at once. The 6 resultant vectors are the answer to that multiplication. The magnitudes are computed from these results as above.
I get the magnitudes of the resultants (to 2 decimal places) to be ...
37.23, 3.89, 42.04, 28.50, 32.04, 41.10
Ok so you are correct that x is input and y is output
the
you could be talking about a function in general or a kind of function normally used called a one-to-one function which I will assume you are talikning about
one-to-one funciton has that for every input, there is only 1 output, ie, x never repeats with a diffent y
example
(1,2), (2,2) is a function since x didn't repeat
(1,2), (1,3) is not since x repeats with a different y
points given are
(-5,1),(-3,-2), (3,0),(1,1),(2,0),(6,4)(8,-2),(8,7)
we see that the points (8,-2) and (8,7) make it not a function since it is the same input (8) that gives 2 different outputs
professor octavious is wrong since 8 repeats
Answer:
b = 3
Step-by-step explanation:
the area of the parallelogram is 7*b, since we know it is 21, b = 3.
