An open pit mine is being dug in the Buffalo Ridge mountain range. It will be 550 feet across and 290 feet deep. Based on sampling of the area, experts project that the company will be able to retrieve an average of about 0.115 ounces of gold per ton of ore and waste mined. The mine company estimates the total cost of production will be $80 million. (Assume the shape of the pit is a perfect cone.) (a) What would be the volume of ore and waste material removed during its mining operation? (b) How many ounces of gold should the company expect to recover from this mine? (Assume one ton is equal to 10 cubic feet.)

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days: f(n) = 10(1.02)n1. Starting from 0 days, plug x-values into our function to find out how many days it takes for the plant to grow to 11.04 cm2. Write a compound inequality to show the reasonable domain of the plant growth:3. What is the y-intercept of our function? 4. What does the y-intercept of the graph of the function f(n) represent? 5. What is the average rate of change formula for exponential growth functions?6. Plug and chug n= 1 to n = 5 into your formula above. Show all work! 7. What does the average rate of change answer represent?

If A is the center of the circle, then which statement explains how segment EF is related to segment GF? Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles. A. segment EF ≅ segment GF because both segments are perpendicular to radii of circle A. B. segment EF ≅ segment GF because both segments are the same distance from the center of circle A. C. segment EF ≅ segment GF because the inscribed angles that create the segments are congruent. D. segment EF ≅ segment GF because the tangents that create the segments share a common endpoint.
