I want points for the question thanks
In order to solve this problem, we need common denominators. 1/4 multiplied by 3/3 is 3/12. 2/3 multiplied by 4/4 is 8/12. 8/12 + 3/12 = 11/12. We also must add 2 and 16. 2 + 16 is 18. The box weights 18 11/12 pounds.
Answer:
A
Step-by-step explanation:
F(t)=30 sin(pi/3 t)-15
when sin(pi/3 t) = 1, f(t) = 15 => max.
when sin(pi/3 t) = -1 f(t) = -45 .+ min.
period = 2π / (π/3) = 6 hrs.
