Answer:
10x = 10.
Step-by-step explanation:
The equation will contain the x variable only.
Answer:
x = 20
Step-by-step explanation:
Assuming it's a square, all sides are congruent. This would mean that x is in fact 20. This also shows us that since the filled in portion of the square has a length of 4, the unfilled portion has a length of 16.
Answer:
0.45 ft/min
Step-by-step explanation:
Given:-
- The flow rate of the gravel,
- The base diameter ( d ) of cone = x
- The height ( h ) of cone = x
Find:-
How fast is the height of the pile increasing when the pile is 10 ft high?
Solution:-
- The constant flow rate of gravel dumped onto the conveyor belt is given to be 35 ft^3 / min.
- The gravel pile up into a heap of a conical shape such that base diameter ( d ) and the height ( h ) always remain the same. That is these parameter increase at the same rate.
- We develop a function of volume ( V ) of the heap piled up on conveyor belt in a conical shape as follows:
- Now we know that the volume ( V ) is a function of its base diameter and height ( x ). Where x is an implicit function of time ( t ). We will develop a rate of change expression of the volume of gravel piled as follows Use the chain rule of ordinary derivatives:
- Determine the rate of change of height ( h ) using the relation developed above when height is 10 ft:
