Jonah is looking at some information for the obstacle course he is interested in completing. the x-coordinate is the number of the obstacle, while the y-coordinate is the average time to complete the obstacle, measured in minutes.

(1, 7.25), (2, 7.975), (3, 8.7725), (4, 9.64975)

jonah use an explicit formula to find the average time he will need for the 9th obstacle.

f(9) = 7.25(1.1)^9; f(9) = 17.095
f(9) = 1.1(7.25)^8; f(9) = 8396469
f(9) = 1.1(7.25)^9; f(9) = 60874407
f(9) = 7.25(1.1)^8; f(9) = 15.541

Suppose there is a simple index of three stocks, stock abc, stock xyz, and stock qrs. stock abc opens on day 1 with 4000 shares at $3.15 per share. stock xyz opens on day 1 with 5000 shares at $4.30 per share. stock qrs opens on day 1 with 6000 shares at $4.60 per share. the price of stock abc on day 8 begins at $3.50. the price of stock xyz on day 8 begins at $3.90. stock qrs opens on day 8 with a price of $4.50 per share. assume that each stock has the same number of shares that it opened with on day 1. what is the rate of change of this simple index over 1 week?

Which graph corresponds to the function f(x) = x2 + 4x – 1?

According to modern science, earth is about 4.5 billion years old and written human history extends back about 10,000 years. suppose the entire history of earth is represented with a 10-meter-long timeline, with the birth of earth on one end and today at the other end.
