Answer:

A) zero; cannot

Step-by-step explanation:

In line with the principle of rational expectations, expectation errors are unpredictable. The expectations of all available information will not differ from the optimal projections.The word optimal projection is inexorably intertwined with the best guess in rational expectations theory.

Find tan if sin=1/4 and falls in Quadrant 1
borishaifa [10]
Ok, sin = prep / hyp    

so,  perpendicular  = 1  , and hypo = 4  
so, base = sq. root ( 16-1 ) = root 15

and tan = prep / base  = 1 / root (15)

Passes through (5,7) and(3,1)
den301095 [7]
IF IT IS THE EQUATION OF A LINE YOU ARE LOOKING FOR:
y=mx+c
7-1÷5-3=6÷2=3
y=3x+c (here we substitute in one of the points to find out what C is)
1=(3×3)+c
1=9+c
-8=c

so the equation is: y=3x-8

Can someone explain this or answer?
Ronch [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
