The transformations that can occur to the graph of the function y = cos x that will exhibit changes would be changes to the angle, or changes to the coefficient. The transformations can be viewed as follows:
y = cos x transforms to y = cos (kx)
k > 1 ; a horizontal shrink occurs
0 < k < 1 ; a horizontal stretch occurs
y = cos x transforms to y = A cos x
|A| > 1 ; a vertical stretch occurs
|A| < 1 ; a vertical shrink occurs
Answer:
64
Step-by-step explanation:
16 x 4 = 64
Answer:
b = -24
Step-by-step explanation:
25+(11/12)b=3
Subtract 25 from each side
25-25+(11/12)b=3-25
11/12 b = -22
Multiply each side by 12/11 to isolate b
12/11* 11/12 b = -22*12/11
b = -2*12
b = -24
Answer:
25%
Step-by-step explanation:
20/80 = 2/8 = 1/4
1/4 = 0.25
0.25 x 100 = 25
so 25%
