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:
= 1/3 * sqrt(1/2)
Step-by-step explanation:
sqrt(1/18)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
sqrt(1/18)
sqrt(1)/sqrt(18)
1/sqrt(18)
We also know that sqrt(ab) = sqrt(a) sqrt(b)
1/sqrt(18) = 1/ sqrt(9)sqrt(2)
= 1/(3sqrt(2))
= 1/3 * 1/ sqrt(2)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
= 1/3 * sqrt(1/2)
Answer:
x = -2
Step-by-step explanation:
2x + 7 = 3
Cancel the 7 by subtracting from both sides
2x + 7 - 7 = 3 - 7
2x = -4
2x / 2 = -4 / 2
x = -2
