Answer: The first diagram you selected is the correct visual representation.
Check out the diagram I posted below. The red vertical line is x = 0, aka the y axis. The blue parabola is 3x = y^2. The green horizontal line is y = 6. The region bounded by these curves is the gray shaded region.
Spinning that gray region around the y axis results in the first diagram in your answer choices. The disk in pink is a cross section to help find the volume (through the use of integral calculus).
Answer:
1) 8/15

When dividing by a number, multiply by its reciprocal.
2/5 ÷ 3/4

Answer:
d
Step-by-step explanation:
3x^2+26+35
ac method
3x35=105
105/5=21
21+5=26
3x^2+5x+21x+35
x(3x+5)7(3x+5)
(x+7)(3x+5)
