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:
d = 1.67 miles
Step-by-step explanation:
Given that,
Speed of a person,  
We need to find how many miles can you walk in 30 minutes, given the  same pace.
30 minutes = 0.5 h

Speed = distance/time

So, the person will cover a distance of 1.67 miles
