Answer:
Step-by-step explanation:
first you find that it is t=Tracy and d= Daniel
so the equation is t= d-38*3 now find the answer
Answer:-3 + 12 = 9
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= $86.50
103.8=x+.05x+.15x
103.8=1.2x
103.8/1.2=x
x=86.5
