Assume a mature sequoia tree requires at least 0.6 m^2 of exterior canopy area per cubic meter of trunk volume. Also assume that the canopy can be modeled by a cone whose slant height is 4 times its radius, and that the trunk of the tree can be modeled by a cone whose height is 12 times its diameter. What is the minimum base radius of canopy required for a sequoia with trunk diameter 5 m? Round your answer to the nearest tenth.

The graph shows the prices of different numbers of bushels of corn at a store in the current year. the table shows the prices of different numbers of bushels of corn at the same store in the previous year. previous year number of bushels price of corn (dollars) 2 10 4 20 6 30 8 40 part a: describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. part b: how many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? show your work.

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!
