Answer:

Domain: (-∞,∞)

Range: (-∞,∞)

Step-by-step explanation:

The x variable can take any value, because the function does not have any restriction.

The range of the function is the same because this is a polynomical function.

HELP ME I DONT KNOW HOW TO FIND THE PERIMETER
Phantasy [73]

Answer:

33.08 m

Step-by-step explanation:

angle of ∆ = 131.6 - 90 = 41.6

=> x² = 8²+3²-2(8)(3)cos 41.6°

= 64+9-48(0.75)

= 73 - 36

= 37

x = √37 = 6.08 m

perimeter = (3×8)+3+6.08 = 33.08 m

State two essential conditions for rusting of iron. List two methods of protecting iron from rusting?​
deff fn [24]
<h3>- - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - </h3>

➷ The presence of Oxygen and the presence of slightly acidic water are essentials for rusting of Iron. To protect Iron from rusting, 'grease coating' can be used. This stops the oxygen and water from being able to make direct contact with the Iron. Also, galvanization can be tried. This is where the Iron is coated in a protective zinc coating to prevent it from rusting.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
