### class council determined that its profit from the upcoming homecoming dance is directly related to the ticket price for the dance. Looking at past dances, the council determined that the profit pp can be modeled by the function $p\left(t\right)=-12{t}^{2}+480t+30$, where tt represents the price of each ticket. What should be the price of a ticket to the homecoming dance to maximize the council's profit? Price

### Given f(x)=6x+5​, describe how the graph of g compares with the graph of f. g(x)=6(0.2x)+5 Select the correct choice below, and fill in the answer box to complete your choice. A. The graph of​ g(x) is translated _ ​unit(s) to the left compared to the graph of​ f(x). B. The graph of​ g(x) is translated _ ​unit(s) down compared to graph of​ f(x). C. g(x) has a scale factor of _ compared to​ f(x). Because it scales the vertical​ direction, the graph is stretched vertically. D. g(x) has a scale factor of _ compared to​ f(x). Because it scales the vertical​ direction, the graph is compressed vertically. E. g(x) has a scale factor of _ compared to​ f(x). Because it scales the horizontal​ direction, the graph is stretched horizontally. F. g(x) has a scale factor of _ compared to​ f(x). Because it scales the horizontal​ direction, the graph is compressed horizontally. G. The graph of​ g(x) is translated _ ​unit(s) to the right compared to the graph of​ f(x). H. The graph of​ g(x) is translated _ ​unit(s) up compared to graph of​ f(x).

College Math problems only seem challenging at first, yet what they truly represent is not much harder than high school Math with some equations that are closer to the engineering approach. Approaching your college math helper is essential because your questions may just have to be worded differently. Regardless if you are dealing with equations or need answers to your college math questions, taking a look at college math equations will let you see things differently. Approach college math answers step-by-step. The majority of college math problems with answers represented here will be similar to what you already have.
