Answer:
<em>15.4 </em>
Step-by-step explanation:
= tan51.3° ⇒ u = 4tan51.3° ≈ 5
= cos51.3° ⇒ v = ≈ 6.4
<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>
I don't know where the angle β is, so I will make the assumption that tanβ = h/r
V volume = 60
r radius = 2
h = r tanβ
Answer:
15
Step-by-step explanation:
Can't really see the graph clearly but the range looks like its from 40-70 so 30 and the amplitude is half of that so 15.
Answer: A
Step-by-step explanation: A reference angle is smallest possible angles that terminal side makes with the x- axis. Since 190 degrees is located i the 3rd quadrant we use the formula 190-180 to find the possible answer and in this case it is A, 10.
