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: Collected amount÷total amount x 100
Step-by-step explanation:
Food and drinks = 
x 100 = 50%
Entertainment = 
x 100 = 11% (11.1 - .1 recurring)
Games = 
x 100 = 22% (22.2- .2 recurring)
Donations = 
x 100 = 17% (16.6- .6 recurring)
Double checking - 50 + 11 + 22 + 17 = 100%
Hope this helps! :)
X = 0
X = -2
X = 7
Hope that helped;)
B is 1 because when you plug in they both equal 1
To find the common ratio, divide the second term by the first term
-10 / 2 = -5
to find each term in a geometric sequence, u multiply by the common ratio.....
2 * -5 = -10
-10 * -5 = 50
50 * -5 = - 250 <== ur next term
