Hey..... Nice to see you :)
Let me help you out.
-3|6n -2| + 5 = 8
-3|6n -2| = 8-5
-3|6n -2| = 3
|6n -2| = 3/-3
|6n -2| = -1
Now, solve absolute value
No solutions.
Because absolute value cannot be less than 0.
I hope that's help !
Answer:
543.4 liters
Step-by-step explanation:
The conversion 1 gallon is 3.8 liters can be used as the rate.
To convert gallons into liters, multiply the numbers of gallons by the rate, 3.8.
143 gallons X 3.8 = 543.4 liters
Therefore 143 gallons is 543.4 liters.
This follows from the half-angle identity for cosine.
Answer:
The angle of elevation of the sun is 
.
Step-by-step explanation:
Let 
be the angle of elevation of the sun as shown in the diagram.
Then the side length which is 
feet is opposite to and the side length which is 
feet is adjacent to .
Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.
We solve for to get,
To the nearest degree, the angle of elevation is
