Circle A has center of (−2, 4) and a radius of 4, and circle B has a center of (3, 9) and a radius of 8. What steps will help show that circle A is similar to circle B? A.)Translate circle A using the rule (x − 5, y − 5).
B.)Dilate circle A by a scale factor of 2.
C.)Reflect circle A over the axis.
D.)Rotate circle A 90° clockwise about the center.

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

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

When you answer this can you explain
