Yes; any fraction which involves only numbers counts as a constant term. In fact, basically any expression which does not involve variables - for example, "square root of 2", "e to the power 5", etc., count as constants - meaning they have one and only one value. They don't vary, depending on some variable.
negative five and eleven or one and two
One that doesn't have any variables. for example 2x+7 the term Is +7
a hemisphere?
Yes, one part of the moon is always facing towards the sun, and the other side is always facing away from the sun. One side is in constant light and one side is in constant darkness.
'Dielectric constant' is an archaic term for relative permittivity. They are one and the same.
Divided by two or multiplied by one half.
"Sesqui" means "one-and-a-half."
The term is called half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
It is a constant.
Add a constant number to one term to find the next term
A constant term.
The constant term - the part without a variable - must be equal to the square of one half the linear term - the number in front of the "x". That is, it must be (12/2)2 = 36.
