Ascale drawing of a square object has a scale of 1 in. : 5 mm. the scale drawing has a length of 2.5 inches. find the perimeter and the area of the object in the scale drawing. then find the perimeter and area of the actual object.

Given the function f(x) = log base 4(x+8) , find the value of f^-1(2)

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
