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:
All but the second one
Step-by-step explanation:
The rule of a function is that you can't have the same x values in an expression. You can have multiple y values but not multiple x values.
Answer: in 340 million square miles there are 8.808 x 10^10 hectares
Step-by-step explanation:
C=pid
