Answer:
Step-by-step explanation:
The first derivative simplifies to ...
d/dx( ) = -(x^2 +6x -47)/(x^2 -9x +20)^2
This has zeros that can be found by the usual methods of solving quadratics:
x = -3 ±2√14
The positive value of x corresponds to what I might call an "apex." (See the first attachment.) The negative value is where the function turns around an approaches the horizontal asymptote from below. (See the second attachment.)

According to current overtime pay laws, every hour worked over 40 weekly hours must be paid at a rate of 1.5 times the regular hourly rate. Jason Gomi has worked 2 hours of overtime, his gross wages for the week are:
Jason's gross wages for the week are $430.
Answer:
B
Step-by-step explanation:
Quadratic inequalities are inequalities involving quadratics.
A is not an inequality.
B is an inequality and we can rewrite B as:
So, B is a quadratic inequality, and is the answer.
C is not a quadratic. The x terms are not squared.
Likewise, D is not a quadratic either since no x terms are being squared.
