The integral represents the volume of a solid. Describe the solid. 2π 4 1 y + 4 y2 dy The solid is obtained by rotating the region 0 ≤ x ≤ 2π/y2, 1 ≤ y ≤ 4 about the line y = −4 using cylindrical shells. The solid is obtained by rotating the region 0 ≤ x ≤ (y + 4)/y2, 1 ≤ y ≤ 4 about the line y = 0 using cylindrical shells. The solid is obtained by rotating the region 0 ≤ x ≤ (y + 4)/y, 1 ≤ y ≤ 4 about the line y = 0 using cylindrical shells. The solid is obtained by rotating the region 0 ≤ x ≤ 1/y2, 1 ≤ y ≤ 2 about the line y = −4 using cylindrical shells. The solid is obtained by rotating the region 0 ≤ x ≤ 1/y2, 1 ≤ y ≤ 4 about the line y = −4 using cylindrical shells. Show My Work (Optional)

the answer is 489

step-by-step explanation:

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
