Answer:
The volume of the solid is either 346.5 in³ or 693 in³.
Step-by-step explanation:
The solid can either be a triangular prism or a rectangular cube.
- Consider the solid as a triangular prism.
The volume of a triangular prism is:
Here,
B = base
H = height
L = length
Let,
B = 7 in
H = 9 in
L = 11 in
Compute the volume of a triangular prism as follows:
Thus, the volume of a triangular prism is 346.5 in³.
- Consider the solid as a rectangular cube.
The volume of a rectangular cube is:
The values of L, B and H remains the same as above.
Compute the volume of a rectangular cube as follows:
Thus, the volume of a rectangular cube is 693 in³.
Answer:
Increasing by $66 per day
Step-by-step explanation:
If sales are dropping at a rate of 2 per day, the sales function is:
If price is increasing by $1 per day, the daily price function is:
Revenue is given by daily sales multiplied by daily price:
The derivate of the revenue function gives us the daily rate of change in revenue:
Currently (t=0) her daily revenue is changing by:
Her revenue is increasing by $66 per day.
