\frac{\sqrt{-49}}{(7-2i)-(4+9i)}=\\
\frac{\sqrt{-1*7*7}}{3-11i}=\\
\frac{7i}{3-11i}*\frac{3+11i}{3+11i}=\\
\frac{(7i)*(3+11i)}{3^2-(11i)^2}=\\
\frac{21i+77i^2}{9+121}=\\
\frac{21i-77}{130}=\\
\frac{-77+21i}{130}

so it is the last option

A mold professional uses an antimicrobial chemical in an attic to combat a colony of mold. If the initial number of mold spores
kykrilka [37]

It would take about 57 hours for the number of spores to be less than 500 spores.

<h3>Exponential Function</h3>

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y is the number of pores after x hours.

a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:

6200(0.8)^\frac{x}{5} < 500

(x/5) * ln(0.8) < ln(0.08)

x > 56.4 hours

It would take about 57 hours for the number of spores to be less than 500 spores.

Robert collected 330 aluminum cans. If 100 aluminum cans weigh 4 pounds, and the recycling center is paying 25 cents a pound, ho
labwork [276]
First, determine the weight of 330 cans with the given conditions,
                    (330 cans) x (4 lbs / 100 cans) = 13.2 lbs
Then, the price is determined by multiplying this weight to the price that the recycling center is paying,
                         (13.2 lbs) x (25 cents / lb)  = 330 cents = $3.3
Thus, Robert will be paid $3.3.
