Answer:
d forms a proportion
Step-by-step explanation:
3x5=15,4×5=20
so they both increase protionally
therefore they are protional
Answer:
A) When using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. True.
The Shell method is a technique used to find the volume of a solid of revolution. Here, we take thin shells with axis coinciding with the axis about which the region whose volume is to be found, is revolved.
B) If a region is revolved about the y-axis, then the shell method must be used. False.
This method can be used with any axis of rotation.
C) If a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y. True.
The washer method uses thin disks with infinite width but the shell method uses thin concentric shells with infinite width about the axis of revolution. So, the statement is true.
Answer:
2 hours, 26 minutes
Step-by-step explanation:
2 boxes of 21 parts = 42 total parts
3 minutes per part = 42 x 3 = 126 minutes
10 minutes per box to package = 10 x 2 = 20 minutes
126 + 20 = 146 minutes
2 hours = 120 minutes
146 - 120 = 26
Final Answer: 2 hours, 26 minutes
Answer:
101.25
Step-by-step explanation:
75.00 x 35% = 26.25
26.25 + 75.00 = 101.25
