Answer:
31pi
Step-by-step explanation:
Answer:
Step-by-step explanation:
amplitude of oscillation a = 12 / 2 = 6 inches.
time period T = 2 s
b = angular frequency = 2π / T
= 2π / 2
= π
so putting the values in the equation
d = a cos ( b t )
d = 6 cos ( π t )
Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.
2x + 25 + 25 = 180
2x = 130
x = 65
I think the answer is going to be a
