The archimedean snail, used in ancient times for irrigation consisted of a wooden spiral encased in a cylinder. The snail would be slanted into water at an angle of about 25° with the horizontal. Turning the cylinder caused the water to climb the spiral. About how long should a cylinder be to raise water to a height of 2 meters?

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.

answer: 1, 3 and 5 are correct

step-by-step explanation:

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
