A chemist has 50 g of the isotope gold-196 which has a half-life of one week. This means that the amount of the sample decreases by half each week. Determine the equation in the graph of its solution set to represent the amount of gold-196 over the course of several weeks. (Choices in Photo Above)

Which of the following is true about the graph of f(x)=7^x. select all that apply. a= it intercepts the x axis b=it intercepts both axis c=it intercepts neither d=it intercepts the y axis

Choose all that apply. select all of the fees a credit card may have. annual fee apr balance transfer fee cash advance fee late fee overdraft fee over-the-limit fee
