Answer:
4.9361
Step-by-step explanation:
Rieman sum = ∫∫ΔA
ΔA = ΔxΔy
Δx = = = pi/2 = Δy
ΔA = pi/2 * pi/2 =
Evaluating at the four corners
=
= 2
∫∫ΔA = 2 * = = 4.9361
Answer:
i think 32 im not really sure
Step-by-step explanation:
Let n be number of days and C the total cost;
Charges by Day and Night kernel,
C=15+20n
Charges by Home away from Home;
C=5 + 30n
The system of equations then is;
C=15+20n
C=5+ 30n
Answer:
14 panels
Step-by-step explanation:
Area of four walls is given by 2*(length + width)*height
_______________________________________
Given dimension
Length = 16 feet
width = 12 feet
height = 8 feet
Thus, area of four walls of office = 2(16+12)8= 448
_____________________________________________
dimension of paneling sheets
length = 8 feet
width = 4 feet
area of paneling sheets = 8*4 = 32 sq. feet
Let the number of paneling sheets required by n
thus, total area of n paneling sheets = n*area of paneling sheets = 32n
This, area of paneling sheets (32n) should be same as 448 area of four walls
as given " I have 4 feet by 8 feet paneling sheets for the walls"
thus,
32n = 448
n = 448/32 = 14
Thus, 14 panels are needed.
