this problem is tricky, if you actually draw it out you will see the side opposite to A is the adjacent side to C which means sin(A)=cos(C)=5/13
Hope this helped!

Answer:
Step-by-step explanation:
For some growth factor f each year, the growth factor over 20 years is given as ...
f^20 = 1 +0.51 = 1.51
Then the growth factor in 10 years is ...
f^10 = (f^20)^(1/2) = √1.51 ≈ 1.22882
__
a) In the 10 years between 1998 and 2008, the price of a basic haircut would rise to ...
$18 × 1.22882 ≈ $22.12 . . . price in 2008
__
b) In the 10 years between 2003 and 2013, the price of a basic haircut would rise to ...
$19.95 × 1.22882 ≈ $24.51 . . . price in 2013
Answer:
(a) (-∞, -8) (-6, -4) (-2, ∞)
(b) -6, -2
(c) negative
(d) 5
Step-by-step explanation:
(a) A function is "decreasing" when the y-value decreases as the x-value increases.
⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)
(b) Local maxima are the points on the function where it reaches a maximum.
⇒ maxima at x = -6 and x = -2
(c) negative
(d) 5
The <em><u>correct answer</u></em> is:
639.4 minutes.
Explanation:
Saturn takes 10 hours, 39 minutes and 24 seconds to make a complete rotation.
10 hours × 60 minutes per hour = 600 minutes.
600 minutes + 39 minutes = 639 minutes.
24 seconds out of 60 seconds per minute = 24/60 = 0.4.
This gives us 639+0.4 = 639.4 minutes.
