Answer:
π/10
Step-by-step explanation:
When we rotate the region about the y-axis, we get something that looks like a volcano, or a bundt cake. Instead of slicing this into flat washers, we'll slice it in concentric rings, or "shells".
Each shell has a radius x, a thickness dx, and a height y. The volume of an individual shell is:
dV = 2π r h t
dV = 2π x y dx
Since y = x² − x³:
dV = 2π x (x² − x³) dx
dV = 2π (x³ − x⁴) dx
The total volume is the sum of all the shells from x=0 to x=1.
V = ∫ dV
V = ∫₀¹ 2π (x³ − x⁴) dx
V = 2π (¼ x⁴ − ⅕ x⁵) |₀¹
V = 2π (¼ − ⅕)
V = π/10

Answer: of quinoa,
of flaxseed,
of soy protein.
Step-by-step explanation:
<h3> The missing table is attached.</h3>Let be "q" the amount of cups of quinoa you'd need to use making the granolas with 3 cups of oats.
Based on the table you can write the following proportion:
Solving for "q", you get:
Let be "f" the amount of cups of flaxseed you'd need to use making the granolas with 3 cups of oats.
With the data given in the table you can write the following proportion:
Solving for "f", you get:
Let be "s" the amount of cups of soy protein you'd need to use making the granolas with 3 cups of oats.
Using the table you can write this proportion:
Solving for "s", you get:
