Answer:
B
Step-by-step explanation:
The slope of the function is most positive either side of x=0 and x=2π.
On the interval [0, π/4], the average slope is

On the interval [7π/4, 9π/4], the average slope is

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].
Sine (28) = opposite / hypotenuse =
0.46947 = opposite / 28
opposite = 0.46947 * 28
<span><span><span>opposite side = 13.14516
</span>
</span>
</span>
cosine (28) = adjacent / hypotenuse =
0.88295 = adjacent / 28
adjacent = 28 * .88295
<span><span><span>adjacent side = 24.7226
