Answer:
Pendulum will swing by an angle 0.666π
Step-by-step explanation:
We have given arc = 
And length of the pendulum l = 150 cm
Length of the pendulum will be equal to radius of the pendulum so r = 150 cm
Arc is given by 
So 

So pendulum will swing by an angle 0.666π
Part A:
-np - 70 < 40
+70
-np < 110
-n < 110/p
Part B
4w-7k=28
-7k=28-4w
7k=4w-28
k=4/7w-4
Solution:
<u>Note that:</u>
- Given inequality: 12p < 96
<u>Dividing both sides by 12:</u>
- 12p < 96
- => 12p/12 < 96/12
- => p < 8
Correct option is A.
