representative rectangle within the region at hand. (as:) 5) Use the same region as in problem#3. Revolve the region about the line x -1. Use disk or washer method to setup the integral (do not evaluate). Make sure to include the representative rectangle within the region at hand. (ans: ) 6.) Revolve the region bounded by the graphs of y -2x+3, y x x-0 about the x-axis. Use the Disk or Washer method. (ans: 4m) 7.) Use the region generated by the ordered pairs (4,0), (4,2) , and (6.2) revolved about the y- axis a) Use the disk or washer method to find the volume. (ans: 5) b) Use the Shell method to find the volume. (ans: ) 8.) Use the region generated by the graphs of y -V25-x2,y 5,x 5 revolved about the x-axis. Use the Shell method to find the volume. (ans: 125) 9) Use the region generated by the graphs of y 9-x2 , y 0 , x-0 in Q1 revolved about the line x 3. Use the Shell method to find the yolume
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
