Sinx=1/2
sin30=1/2
therefore x=30 degree
Answer:
7
Step-by-step explanation:
There is a point of inflection at each point where the graph crosses the line y=2. There are 7 points of inflection shown.
__
A point of inflection is where the graph changes from being concave downward to concave upward, or vice versa. For a sine function, that is everywhere the function crosses its midline.
Answer:
C, x ≥ 14.96
Step-by-step explanation:
Step 1: Add 3.408 to both sides.
2.2x − 3.408 (+ 3.408) ≥ 29.504 (+ 3.408)
2.2x ≥ 32.912
Step 2: Divide both sides by 2.2.
2.2x (÷ 2.2) ≥ 32.912 (÷ 2.2)
x = 14.96
