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
Answer: 131 degrees
Step-by-step explanation:
20y-11+4y+6+7y-7=360
31y-12=360
+12. +12
31y= 372
Divide by 31
Y= 12
BC= 4y+6+7y-7
4(12)+6+7(12)-7
BC= 131
Answer: The table and figure are given below,
Solution:
The given equation is
.
put x=0 in the equation.



Similarly find the values of y at different values of x. The values are shown in the table.
From table it is notices that the value of y=-2 for x=0, y=-1 for x=3, y==-3 for x=-3, y=0 for x=6.
Plot these points in the coordinate plane and joint them by a straight line.
The gra his shown in below figure.
Answer:
y=2x-10
Step-by-step explanation:
y+4=2x-6
-4
y=2x-10
