Answer:
y= 5x - 3
Step-by-step explanation:
For the slope, use this formula (y2 - y1) / (x2 - x1)
I used (1,2) and (2,7) from the chart
plug 7 for y2, and 2 for x2
then plug 2 for y1, and 1 for x1
7-2 / 2-1 = 5/1 = 5 <-- this is the slope.
Find the y intercept by plugging in (1,2) into y=5x + b
2 = 5(1) +b
2= 5 + b (subtract 5 on both sides)
-3 = b
So the answer is y= 5x - 3
The problem ask to fourier series of the trigonometric function base on the data you have been given in the problem, so the answer would be cos(pi/2n) = {(-1)^n/2 - if n is even, 0 - if n is odd} and sin(pi/2n) = {0- if n is even, (-1)^(n-1)/2 if n is odd}. I hope you are satisfied with my answer
Answer:
12/19 or 0.6315
Step-by-step explanation:
You see that the denominator of 3/4 is 4 and the numerator of 16/19 is 16 both 4 and 16 are common factors, so you can reduce this to 3x4/19 then multiply 3/1 x 4/19 to give you 12/ 19 because 3x4 is 12 and 1x19 is 19.
