Using a graph to find the intersection of two curves can be challenging when the point of intersection is not on gridlines or ends up off the graph. Therefore, it helps to know another way to find the intersection without using a graph.
a. Name the algebraic methods you already know to solve linear systems.
b. Use one of the methods you listed in part
(a) to solve for the intersection of
The problem is called self-answering problems because the answers are embedded in the question. For example, how many ways can you arrange the letters in the word “six”? The answer is six. At time t=0, water begins pouring into an empty sink so that the volume of water is changing at a rate V′(t)=cos t. For time t=k, where \(0\leq k\leq \pi/2\)
