Answer:
subtract 1 then divide 2
Step-by-step explanation:
Answer:
C, 3
Step-by-step explanation:
By creating a best line of fit you can get the sets of points (16,50) and (12,40)
Using these to find the slope we can get
-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.
Answer:
y = sin(x- pi/2)
Step-by-step explanation:
Please see the attached image to see your graphs.
By simple inspection we can see that the sine is shifted pi/2 to the right.
We know this because sines are periodic functions with a period T = 2*pi
We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.
And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.
Answer:
-1
Step-by-step explanation:
The remainder of n/4 is 2
n/4 represents the exponent
For example if n=6 then when we divide 6/4 the remainder is 2
if n=6 then i^6 = i^4 * i^2 = 1* (-1) = -1
The value of i^2=-1
i^2 = -i
i^4= 1
So if the remainder of n/2 =2 then it means i^2 = -1
the value of i^n =-1
