Given the pay structures for two different babysitters, determine the number of hours of babysitting at which the two babysitters charge the same amount of money.
A parent is deciding which babysitter to use in the neighborhood. Babysitter A charges $20 per hour and a base rate of $60 per day. Babysitter B charges a base rate of $50 per day and $25 per hour. For how many hours of babysitting do the two babysitters charge the same amount?
Details: Many different kinds of data can be modeled using polynomial functions. An example of a polynomial function would be gas mileage for an automobile. If we compare gas mileage at two different speeds, V1 and V2, the gas required varies as (V1/V2), raised to the third power, (V1/V2)3. Rational functions are also usefu
1. When solving a quadratic equation using the quadratic formula, it is possible for the b2 - 4ac term inside the square root (the discriminant) to be negative, thus forcing us to take the square root of a negative number. The solutions to the equation will then be complex numbers (i.e., involve the imaginary unit i). Questio
A simple pendulum, such as a rock hanging from a piece of string or the inside of a grandfather clock, consists of a mass (the rock) and a support (the piece of string). When the mass is moved a small distance away from its equilibrium point (the bottom of the arc), the mass will swing back and forth in a constant amount of tim
