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

Answer:
It is finite because it has an ending. Infinite has no ending and will keep going forever while this statement has an ending.

Answer:
-4/5
Step-by-step explanation:
Please use a symbol such as x or Ф to represent an angle; your 0 is too easily confused with zero.
If Angle Ф lies in the second quadrant, and sin Ф=3/5, find cos Ф.
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse: sin Ф = opp / hyp = 3 / 5. Thus the opp side has length 3 and the hyp has length 5. By the Pythagorean Theorem,
the adj side has length √(5² - 3²), or √(25-9), or √16, or ±4. Because the angle is in the 2nd quadrant, choose adj = -4.
Then the cosine of this angle is cos Ф = adj / hyp = -4 / 5
