Answer:
Step-by-step explanation:
The point slope form of a line is the form where m is the slope and is a point on the line.
Here the slope is 5 and the point is (2,3).
Substitute and you'll have:
Answer: C
y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Given:
Principal = $10
Rate of simple interest = 2.2% per month
Number of years = 6
To find:
The value of interest.
Solution:
Formula for simple interest is:
...(i)
Where, P is principal, r is rate of interest in % and t is the time period.
Here the rate of interest is defined for per month. So, the time period is also the number of months.
[ 1 year = 12 months ]
Putting P=10, r=2.2 and t=72 in (i), we get
The simple interest is $15.84.
Therefore, the correct option is B.
Step-by-step explanation:
Before the industrial revolution, most of the moth population had white wings. During and after the industrial revolution, the moth population has evolved to have a majority black population. This happened due to changing natural selection pressures. The black moths were able to camouflage in the ‘dark environment’ caused by soot from the industrial revolution. The moths were less linly to be preyed on compared to white moths that stood out in the ‘black’ environment. Over a generation, the allele for white-color, because it offered a disadvantage, becomes ‘weeded out’ of the population.
