r° = 158°
s° = 180° - r° = 180° - 158° = 22°

We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write
... d = 75-12sin(π·t/12)
Answer:
3/5
Step-by-step explanation:
(x - h)² + (y - k)² = 25
(x - (-4))² + (y + (-6))² = 25
(x + 4)² + (y - 6)² = 25
(h, k) = (-4, 6)
The answer is B.
