The length of a snake in a video game doubles every minute. The function f(x) = 10 • (2)x represents the length of the snake in centimeters (cm). The time x = 0 represents when the game started.
A. Label the correct axes with "Length (cm)" and "Time (minutes)."

B. Graph f(x) = 10 • (2)x.

C. On the graph, plot and label the y-intercept.

D. Which values of x make sense in terms of this problem? Explain your reasoning. Make sure your graph shows these values.

The line containing the midpoints of the legs of right triangle abc where a(-5,5), b(1, 1), and c(3, 4) are the vertices.

If (17, 4) is an ordered pair of the inverse of f(x), which of the following is an ordered pair of the function f(x)? a. (17,4) b. (4.17) c. (4,0) d. 0,17)

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
