Match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y = - 9.25. 1. Find the distance from the focus to the point on the parabola. 2. 3 Choose a point on the parabola. 3. Use (x, y). 1 Square both sides and simplify. 4. Set the distance from focus to the point equal to the distance from directrix to the point. 5. Write the equation of the parabola. 6. Find the distance from the point on the parabola to the directrix.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
