52.37 times 1.20(how you calculate tip) =62.84
Answer: D; 3 - 7 = -4
Explanation: Since 3 is the largest value in this equation and the arrow is going to the left (starting at a positive and stopping at a negative), you count backwards 7, which would be subtracting 3 from 7 in this case.
The motion can be modeled as

where
x = the position below the equilibrium position
T = the period of the motion
t = time
The weight returns to its equilibrium position when x = 0.
This occurs when

That is,

Because the weight returns to the equilibrium position when t = 3 s, therefore
T = 12 s
The motion is

When t = 1 s, the position of the weight from equilibrium is

Answer:
You have to use the equation (72+y)=5(4+y) which Y =+13
