Answer:

The material that does not transfer heat well is helium

Explanation:

a thermal insulator. Insulators have the ability to contain the heat of a substance or they are able to limit the heat loss of the substance. They are different form conductors because conductors transfers heat energy

How is the percent efficiency of a machine determined?

NemiM [27]

Since work is the change in kinetic energy, the efficiency of a machine can be stated as the percentage of the output work divided by the input work minus the work lost from to friction and heat. Multiply Eff by 100% to get the efficiency percentage.

Given the function f(x) = 8x3 − 3x2 − 5x 8, what part of the function indicates that the left and right ends point in opposite d

ale4655 [162]

Answer: The degree of the first term.

Explanation:

The function:

$f(x) = 8x^3-3x^2-5x^8$

The left and right ends would be indicated when x is changed to -x. When this is substituted, the change is indicated by the first term because only the degree of first term is odd.

Let the left hand side be donated by -x.

Then,

$f(-x) =8(-x)^3-3(-x)^2-5(-x)^8\\ \Rightarrow f(-x)=-8x^3-3x^2-5x^8$

Hence, the correct option is the degree of the first term indicates the left and right end points of the function.
