If a roller coaster has the potential energy of 250 joules right before it plunges down the track, what is its potential energy half way through the run?

130 joules.

Step-by-step explanation:

Potential energy at height h = mgh  where m = mass, g = acceleration due to gravity.

At the halfway mark the  where the height is h/2 then the potential energy is 1/2 * 260 = 130 joules.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
