Answer:
16
Step-by-step explanation:
Use the method of PEMDAS (Parenthesis, Exponent, multiplication, division, addition and then subtraction.)
When using this order you would do 10-9 first
23 + 5 * (10-9) - 12
23+ 5 * 1 - 12
then 5 times 1
23 + 5 * 1 - 12
23 + 5 - 12
then 23 + 5 and subract 12 from the solution
23 + 5 - 12
28 - 12 =

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

For Ramona to know how much she expects to pay for the carpet she is ordering, she first needs to know how many square foot the the room has.
In getting the area of the room, you multiply one side with the other,
in equation,
19.5 ft x 41.6 ft = 811.2 sq ft.
Then if the carpet costs $9.50 per sq ft, you simply multiply it the area of the room
in equation,
$9.50/ sq ft. x 811.2 sq ft, cancelling out the unit of sq ft
the answer would be $7,706.4
Yes, SAS (Side Angle Side)
