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
Each piece will be 1/9 of the total length of the original board.
1/9 of 8 ft is <em>8/9 foot</em>.
That's the same as <em>(10 and 2/3) inches</em>.
Since there is no x it’s simply moving down 4. There is no movement left or right (x) just simply down for -4.
To solve this problem you must follow the steps below:
You have a/b=8/15, Then:
1. You must divide in both side of the given proportion by 8:
a/bx8=8/15x8
2. When you simplify, you obtain:
a/8b=1/15
3. Now, you must multiply both sides by "b", as below:
axb/8b=1xb/15
4. Finally, when you simplify, you have:
a/8=b/15
