I'm not sure what you're asking but they each took 5 hours of work into one hour..
Answer:
64π/5 cubic units.
Step-by-step explanation:
The line x = 2 and y = x^3 intersect at the point (2 , 2^3) = (2, 8).
The required volume = volume of the cylinder with height 8 and radius 2 - the volume of shape form between the curve and the y axis when revolved about the y-axis.
Using the disk method for volumes of revolution:
Note that x = y^1/3 so:
the second volume = Integral π ((y^1/3)^2) dy between y = 0 and y = 8.
= 3/5 y^5/3 * π between 0 and 8
= 96π/5.
The required volume = π 2^2 *8 - 96π/5
= 32π - 96π/5
= 64π/5.
Answer:
work will be explained in the explanation portion
1. x = 3
2. y = 5
3. x = 13
4. y = 2
5. c = 7
6. a = 34
7. unsure but -5/12
8. 16
Step-by-step explanation:
1. 11 - 8 = 3
2. 16 + 9 = 25 5 x 5 = 25
3. 9 + 4 = 13
4. 10 - 4 = 6 3 x 2 = 6
5. 45 - 3 = 42 6 x 7 = 42
6. 23 + 11 = 34
7. 2/3 = 8/12 1/4 = 3/12 8/12 - 3/12 = 5/12
8. 14 divided by 7/8 = 16 (use keep change flip)
HOPE THIS HELPS!! <33
Answer:$114.47
Step-by-step explanation: $38 divided by 8 is 4.75$
and then u add 3.50 to one of the packages which is 8.25$
and then u add the rest by $5 which u get 9.75$
so at the end u add them all up thenaswer would be $114.47
83/9 is a improper fraction
when it is 9 2/9 it is a mixed and the numbers like 1, 2, 3,4 are whole because no fractions are there
