Answer:

Step-by-step explanation:
The midline is set on
, when the sine function is equal to zero, eliminating the effect from amplitude. The midline is a horizontal line. Hence, the equation of the midline is:

Answer:
h = -19.4
Step-by-step explanation:
1. Take the constant on the left side of the equation by changing the positive to a negative ---> h = -9.7 -9.7
2. Solve the right side, and you have yuor answer. ---> h = -19.4
For the first one,
you multiply 5x and -5 to get -25.
Then you move the constant to the right and change the sign to get 3x= -21 +25.
Calculate the sum of -21+25 to get 4.
Divide both sides of the equation by 3 to get x=4/3.
So then your final answer is x=4

For the second one,
Distribute 7 through the parentheses to get 14x + 14+8=120
The you add 14+8 to get 22. Your equation should be 14x+22=120
Move the constant to the right side and change its sign to get 14x=120-22
Subtract 120-22 to get 98. Now your equation should be 14x=98
Divide both sides of the equation by 14 to get x=7.
Your finial answer for the second one should be x=7.

I hope this made sense.
u is at (1,-2)
V is at (-6,-6)
using distance formula it is about 8.06 long
so Answer is C
