Answer:
d
Step-by-step explanation:
If x represents the slant height, the graph would be a straight line.
If x represents the radius, the graph would be a parabola.
Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.
We are looking for g(x). Answers a and b are wrong.
In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.
So the domain is x > 5.
d is your answer.

Answer:
Step-by-step explanation:
<h3>Part B</h3>
Assumed the dimensions of the top and bottom parts are identical.
Since the cylindrical part has total height of 1.8 cm and the hemisphere volume is transferred to bottom part and the cone part is still full, the value of h is the difference of the total height of cylinder and full part of the top section of cylinder:
- h = 1.8 cm - 0.3 cm = 1.5 cm
<h3>Part C</h3>
Find the volume of sand in the bottom part. It consists of a hemisphere and a cylinder of 1.5 cm height.
- V(cylinder) = πr²h = 3.14*(2.6/2)²*1.5 ≈ 7.96 cm³
- V(hemisphere) = 2/3πr³ = 2/3*3.14*(2.6/2)³ ≈ 4.6 cm³
<u>Total sand in the bottom part:</u>
<u>Time taken:</u>
- 12.56 / 0.05 = 251.2 seconds = 4 min 11.2 seconds
