Answer: D
Step-by-step explanation: I believe it's D because there's a STRONG, POSITIVE RELATIONSHIP so they're both increasing, but there's no correlation
So a complementary angle is going to equal 90 degrees.
The equation is : x - 10 + 4x - 10 = 90
Then, add together the matching terms : 5x - 20 = 90
Add 20 to both sides : 5x = 110
Then divide both sides by 5 : x = 22
Insert the value 22 into the first equation : (22 - 10) + (4*22 - 10) = 90
Solve : 12 + 78 = 90
Angle UVW = 12 and angle XYZ = 78

Answer:
3.5 to 20.5 hours
Step-by-step explanation:
The range of the sine function is -1 to 1, so the range of H will be ...
-8.5 +12 = 3.5
to
8.5 +12 = 20.5
The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.
Answer:
D) 3/15
Step-by-step explanation:
(-2/5) - (-9/15) = (-6/15) - (-9/15) = (-6/15) + (9/15) = 3/15
