Answer:
The given equation is
Which is the definition of the angle of repose.
<em>Remember that the angle of repose refers to the angle between the horizontal plane and the inclined side of the cone formed when we allow to fall freely granular materials.</em>
We know by given
Replacing these values, we have
Therefore, the angle of repose is 38.29° approximately.
Now, if the base diameter is 104 feet, the height would be
Therefore, the height would be 65.8 feet, assuming that the angle of repose is the same.
Answer:
k=-10=1.357816691600547or k=
-10=-21.35781669160055
Step-by-step explanation:
k^2-20k=29 |+100
k^2-20k+100=29=100
k^2-2x10xk+(-10)^2=129
(k-10)^2=129
|k-10|=
case 1 k is a positive number
case 2 k is a negative number
