Answer:
D. 6√3.
Step-by-step explanation:
x^2 = 108
x = +/- √108
x = +/- √36 * √3
x = +/- 6√3
93 x 10^6 =
93 x 1,000,000 = 93,000,000
Simplify both sides of the equation
Subtract 2 from both sides
Divide both sides by 5


OR

Given that,
A population p of migrating butterflies changes over time it is represented by the equation
Where w is number of weeks.
To find,
The population after 2 weeks.
Solution,
We have,

Put w = 2 in the above equation.

So, the population after 2 weeks is 64000
.
Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller. To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50. So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100. Therefore the percent decrease is 30%
