Answer:
-0..072 Inches Per Minutes
Step-by-step explanation:
Volume of a Cylinder, V =
Given l=32 Inches, r=0.5 Inches
V =
Since the Volume is constant,
After one minute,
- Length of the Cord=32+18=50 inches
Since the volume is<u> constant</u>
Therefore:
Therefore, the radius of the cord is reducing at a rate of 0.072 Inches per minute.
Answer:
A.
Step-by-step explanation:
The answer is C. That is where the graph crosses the x axis
Answer:
1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2
2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2
3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2
4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2
5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.
rising rapidly at first then slowly keeps rising then it goes straight longitude and its a flat line
