Question

I need help with this please! I want someone to go through the steps with me, not tell me the answer. Thanks~! ^_^

Answer 1

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

@Luigi0210 Do you think you can help me with this question?

Answer 5

The first part of the equation, 345, would most likely be the starting amount.

With the 1.30 as the rate of growth.

and x being equal to the number of weeks

Answer 6

With 1 being equal 100%

So anything less than 1, would be a decrease

And anything greater than 1, being a growth.
