The dimensions would be 2 by 2.
We are fencing in 3 sides. The southern side is twice as expensive as the other two sides; the eastern and western sides together equal as much as the southern side. We have $80 to spend.
20x+10x+10x = 80
40x = 80
x = 2
This means that we can have 2 feet on all sides, for a total of 10(2)+10(2)+20(2)= 80.
Find volume
volumecone=(1/3)(h)(pi)(r^2)
hemisphere is just a half sphere aka, 1/2 times volume of sphere so
hemisphere=(1/2)(4/3)(pi)(r^3)
fnd their volumes don't evaluate the true value till end, leav pi as pi
(or use pi key for graphing or scientific calculators)
cone
d/2=r
10/2=r=5
h=15
V=(1/3)(15)(pi)(5^2)
V=(5)(pi)(25)
V=125pi
hemisphere
V=(1/2)(4/3)(pi)(5.5^3)
V=(4/6)(pi)(166.375)
V=110.91666666666666666pi
which is bigger
125pi or 110.916666666666666666pi
125 pi
by how much?
125pi-110.91666666666666pi=14.08333333333pi
aprox pi=3.14
14.08333333*3.14=44.2217
rond
44
answer is CONICAL will hold 44 cubic feet more
Using it's concept, it is found that the average rate of change of the function from x = -1 to x = 5 is of -1.
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem, the output changes by -6(from 7 to 1) when the input changes by 6(from -1 to 5), hence the average rate is given by:
r = -6/6 = -1.

Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)
m = 
= 
= -
