The forces F1, F2, F3.-..., F, acting on an object are in the zero vector.
F1+F2 + F3+ ... + Fn = 0
The forces F1 = 71 - 4j and F2 = 31+ 2j are acting on an object.
a. Find the resultant force.
b. What additional force is required for the given forces to be in equilibrium?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
