Which of the following two-dimensional shapes can be rotated to create a cone?

Right triangle
Square
Circle
Ellipse

Right triangle

Step-by-step explanation: Right triangle because when you rotate it, it becomes a cylinder. The bottom will come all the way around and become the radius, but the point at the top stays in the same place.

Hope this helps :)

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
