A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is an R19 and what is it used for?

R19 can refer to insulation as well as to a form of explosives. The Renault 19 is a car which is sometimes calls an R19. R19 insulation is usually found as batts insulating the walls of homes.


What is the most common R-value recommended for residential ceiling insulation?

R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.


How Thick is R19 insulation?

R-19 is 6.25 inches thick.


What is the thickness of R-19 insulation?

Depends on the MFG, and type. I have seen R19, from 5 inch to 6.5 inch in thickness.


What is the difference in percent gain between R-19 and R-30 insulation in an attic?

57% gain. A R30 would be the same as a R19 + a R11 batt.


What is the formula used to determine insulation resistance in a motor?

R = U/I (Ohm's law) R = Insulation resistance. U = Test votage. Value depending on motor rated voltage. I = Measured current


What value does 10 insulation give?

If you are referring to the R value of insulation, then 10 would be the 'thermal resistance' value of the insulation. A value of 10 is about what 3 1/2 inches of fiberglass batt insulation would give you. That is what you might put within your exterior walls if you are using wood studs. The higher the R value the better insulation you will have. When you add up all of the R values of the materials that make up your exterior wall you will get your total value. Depending on where your building is located, and the climate in that area, you will need to adjust your insulation accordingly.


What does a low U-value mean?

It can also be referred to as an 'overall heat transfer co-efficient' and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. A low U value usually indicates high levels of insulation.


What does an R-Value tell you?

It is the measure of insulation against heat/cold afforded by varying thicknesses and composition of construction insulation materials. The higher the "R" Value the better the insulation characteristics.


Is r-value good or bad?

it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.


How is insulation measured?

Floors, attics and walls all require insulation of different R-Values which are measured by the thickness of the insulation. The R-Value determines how well the insulation will resist heat flow. The higher the R-Value the more resistance it has to heat and cold. If you are adding to existing insulation there is another factor to consider. You will have to determine the R-Value of the existing to know how much additional insulation to add


Looking for floor insulation for a good price?

If there is a ceiling below the floor then you can insulate the ceiling and that will insulate the floor using traditional insulation. If you are looking to insulate a basement floor then one of the cheaper forms of insulation is called Thermo-Tech Ultra Light flooring insulation. There are other forms that you can use but this is the least expensive.
