Nine dimes and nine nickels are equal
to two nickels and how many
quarters?

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

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
