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 mol
Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.


Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:


345(1.30)^4 = \boxed{985.35}


Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.

Evaluate and simplify the following complex fraction.
aniked [119]
<h3>Answer:  -22/7</h3>

=========================================================

Explanation:

The fraction 6/(-7) is the same as -6/7

We have the two fraction -6/7 and 3/11 being divided

The denominators are 7 and 11 respectively.

The LCM of those two numbers is 77 since 7*11 = 77

If we multiply each of those fractions (-6/7 and 3/11) by 77, then we'll clear out those inner denominators to simplify this complex fraction into a nicer one.

77*(-6/7) = -66

77*(3/11) = 21

This means the original complex fraction becomes -66/21

We can further simplify this by dividing each part by the GCF 3

-66/3 = -22

21/3 = 7

Therefore, the final answer is -22/7
