(a) use a graphing utility to graph the function and (b) state the domain and range of the function. $$s(x)=2\left(\frac{1}{4} x-\left[\frac{1}{4} x\right]\right)$$
The work \(W\) done when lifting an object varies jointly with the object's mass \(m\) and the height \(h\) that the object is lifted. The work done when a 120 -kilogram object is lifted 1.8 meters is 2116.8 joules. How much work is done when lifting a 100 -kilogram object 1.5 meters?
Use a graphing utility to graph the function. Be sure to choose an appropriate viewing window. $$f(x)=(x-1)^{3}+2$$
Find the difference quotient and simplify your Answer: $$f(x)=4 x^{2}-2 x, \quad \frac{f(x+h)-f(x)}{h}, \quad h \neq 0$$
Finding a Mathematical Model In Exercises \(41-50\), find a mathematical model for the verbal statement. Newton's Law of Universal Gravitation: The gravitational attraction \(F\) between two objects of masses \(m_{1}\) and \(m_{2}\) is jointly proportional to the masses and inversely proportional to the square of the distance \(r\) between the objects.
