I the answer is 20/5 but you have to put it in abc
20 I apologize if this is wrong
Answer:
2cm of Rainfall
Step-by-step explanation:
When the no. of mosquitoes is the highest the slope of graph will be zero
so if we differentiate this function and equate to zero we can find the rainfall amount that gives maximum number of mosquitoes in centimetres.
m(x)= -x²+4x
differentiate
d(x)/d(m(x))= -2x+4
equate to zero
-2x+4=0
2x=4
x=2
answer: 2 cm of rain
You will need to use the Pythagorean Theorem, actually a derivative of it sometimes called the "distance formula" to find the length of the segments between two points. Mathematically the distance is:
d^2=(x2-x1)^2+(y2-y1)^2
d=√(dx)^2+(dy)^2)
