Answer:
Option C, dP/dt=1/5P
Step-by-step explanation:
The change is population of insects is directly proportional to the rate of change of population
Hence,
Or
where K is the proportional constant
We will find the value of k
Keeping the given values of rate of change of population and population in above equation, we get -
Hence,
Point A is translated to A" by T(0, -6), since A has been shifted 6 units down
check the picture, the translated triangle is A"'B"'C"'.
clearly the angle between B"'A"' and B"A"' is 90 degrees, so we can complete the transformation by a 90° clockwise rotation or a 270° counterclockwise rotation.
from the choices given, we see that is is a 270° counterclockwise rotation.
Answer: <span>A.(o,-6). Ra,270</span>
