Answer:
The equation is 
Step-by-step explanation:
Let the exponential function is 
, where m is the angle of the swing forward and n is the number of swings.
Here, a and b are constants.
Now, for n = 1, m = 18 degrees and for n = 2, m = 13.5 degrees.
Therefore, the two equations that we can write are :
............. (1) and
................. (2)
Now, solving the above two equations we get,
⇒ b = 0.75
So, from equation (1) we get, 
Therefore, the equation is (Answer)
Answer: 24

Answer:
c
Step-by-step explanation:
ANSWER: -60
EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:
−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.
−10−|−20−30|
= −10−|−50|
= −10−50
= −60
