An object is attached to a spring that is stretched and released. The equation d= -8*cos((pi/6)*t) models the distance, d, of th
e object in inches above or below the rest position as a function of time, t, in seconds. Approximately when will the object be 6 inches above the rest position? Round to the nearest hundredth, if necessary.

Answer:
Please see the attached graph for answer.
The object will be at 6 inches above the rest position at approximately 4.62 seconds
Step-by-step explanation:
To easily solve this problem, we only need to graph the equation in a calculator and find the solution at d = 6 inches
We can see in the graph that at t = 4.62 the height is equal to d = 6.001 which is the approximation of the required value.
The graph is cyclic, because it is modeled as an harmonic oscillator without any damping.

Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student
Now left student = 10 -1 = 9
So number of ways to assigned double student
Now left student = 9-2 = 7
So number of ways to assigned triple student =70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
