Answer:
it is number 1. because the answer above is equivalent to number 1
In this case, we must use trigonometry to find the value of x:

Thus the value of x rounded to the nearest tenth is <u>8.2</u>
<u></u>
Hope that helps!
Answer:
h = 48
because 32 + 3h + 4 = 180
32 + 4 = 36
36 + 3h - 36 = 180 - 36
3h = 144
3h/3 = 144/3
h = 48
Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.
