The given equation is :

$xy = - 2$

1. The relationship such that dependent variable (y) is isolated is :

$y = \dfrac{ - 2}{x}$

2. The table accompanying this equation :

x = -4 and y = 0.5

x = -1 and y = 2

x = - 0.5 and y = 4

x = 0 and y = undefined

x = 0.5 and y = -4

x = 1 and y = -2

x = 4 and y = -0.5

3. graph of the given equation is in attachment ~

What is the volume of the cone to the nearest cubic millimeter? (Use π = 3.14)

Goryan [66]

Answer:

= 45.791666666666 mm^3

Step-by-step explanation:

Volume of a cone is given by

V = 1/3 pi r^2 h

We know the diameter = 5

The radius is 1/2 the diameter

r = 5/2

The height is 7

Using pi = 3.14

V = 1/3 *(3.14) * (5/2)^2 *7

= 1/3 *(3.14) * 25/4 *7

= 45.791666666666
