Answer:
Because when you are finding slope the line must be linear and because it is linear it doesnt matter which point you get because you get the same answer (you can try it yourself)
Step-by-step explanation:
Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b
8 = 2π/ b
Solve for b: 2π/8 or π/4
Equation: y = 2 cos (π/4 (x))
Answer:
Step-by-step explanation:
To find the answer we have to first group the like terms:
therefore
so
Find the slope of the line using the two points by plugging them into this formula: m = y2 - y1 / x2 - x1 where the two points are x1, y1 and x2, y2 and m is the slope.
A, 25.376. This rounded to the nearest hundredth would be 25.38 not 25.37.
