Which statement best describes the excluded values of a rational expression?
2 answers:
<h2>Answer:</h2>
Option: B is the correct answer.
B. The number of excluded values of a rational expression cannot exceed the degree of the denominator.
<h2>Step-by-step explanation:</h2>We know that a rational expression is a expression of the form:
where p(x) and q(x) are polynomials.
Excluded value--
The excluded value of a rational expression are the values where the denominator of the expression is zero.
Also, the number of zeros of a polynomial is always less than or equal to degree of the polynomial.
Hence, the number of excluded values of a rational expression cannot exceed the degree of the denominator.

Answer:
Step-by-step explanation:
Power is defined by work over time. In physics, work can be defined as the energy transferred over from an applied force over some distance. As a formula:
, where F = force applied and d = distance that force is applied over.
*It is worth noting that F must be parallel to the distance travelled. If it is perpendicular, no work is done, and if it is at an angle, find the parallel component and use that for F.
In this case, the force applied must counter the force of gravity on Martha, which is given by , where m = Martha's mass and g = gravitational constant 9.8 m/s/s. Therefore,
. Since she raises her body 4.0 meters, the work done must be
.
Since power is equal to work over time and t = 2.3 seconds, we have:
