Answer: 3.845312455 just put it in a scientific calculator
You write it as $101,000.
Step-by-step explanation:
The particle is at rest when the derivative of x(t), which is its velocity, is zero, i.e.,
Since its derivative is
Equating this to zero, we get
This is a familiar quadratic equation whose roots are
This means that the particle will be at rest at t = 3 and t= 4.
Answer:
216
Step-by-step explanation:
From what I could tell, the model is a cube with a side length of 6. That means all sides have a length of 6 cm. You just have to do 6*6*6= 216
Hope this helps!! I'm not sure why there is a 42 at the bottom though.
