A) Use the trigonometric function and ratio cos(x) = A/H. (Adjacent/Hypotenuse) 1. cos(x) = 135/H 2. H*cos(16°) = 135 3. H = 135/cos(16°) ***Make sure calculator is in degree mode*** 4. H = 140.44 ft (rounded to two decimal places) ________
b) Use the function and ratio tan(x) = O/A (Opposite/Adjacent) 1. tan(x) = O/A 2. tan(16°) = O/135 3. 135*tan(16°) = O 4. O = 38.71 ft (two decimal places)
If c is a positive real number, then the graph of
f(x – c) is the graph of y = f(x) shifted to the right
c units.
Horizontal Shifts
If c is a positive real
number, then the
graph of f(x + c) is
the graph of y = f(x)
shifted to the left
