You take 300 - 99 you get 201 so you still have 201lbs so then 3 times 67 is 201 so it would be B
Step-by-step explanation:
0.75a + 2(0.90) = 27.60
is the correct answer
Answer:
T(t) = 3sin((t-5)π/30)
Step-by-step explanation:
5 minutes after Thomas ties it on, the torque is zero and increasing. So, the sine function is shifted right 5 minutes. The maximum value is 3, so that is the multiplier of the sine function. The period is 60 minutes, so the coefficient of t is (2π/60) = π/30. The function you want is ...
T(t) = 3sin((t-5)π/30)
