Answer:
Explanation:
The statement is expressed as
y
∝
1
x
inverse means
1
variable
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
⇒
y
=
k
x
To find k use the given condition that y = 8 when x = 4
8
=
k
4
⇒
k
=
4

8
=
32

V=PiR^2H/3
Pi = 3.14 (use pi symbol on calculator)
R is the radius if the cones bottom
H is the height of the cone
Answer:
y=(x+7)2(2x+1)(x−4)
y=2x4+21x3−4x2−399x−196
Step-by-step explanation:
Find the mean, median, and mode(s) of the data. Do not round. 2, 8, 10, 12, 56, 9, 5, 2, 4
Mariana [72]
The mean is 12, the median is 8, and the mode is 2.
