Answer:
136.73972
Step-by-step explanation:
A=lw+l(w
2)2+h2+w(l
2)2+h2=6·5.2+6·(5.2
2)2+92+5.2·(6
2)2+92≈136.73972
Answer:
(a)
(b)5,832 Mosquitoes
(c)5 days
Step-by-step explanation:
(a)Given an original amount 
at t=0. The population of the colony with a growth rate 
, where k is a constant is given as:
(b)If 
and the population after 1 day, N(1)=1800
Then, from our model:
N(1)=1800
Therefore, our model is:
In 3 days time
The population of mosquitoes in 3 days time will be approximately 5832.
(c)If the population N(t)=20,000,we want to determine how many days it takes to attain that value.
From our model
In approximately 5 days, the population of mosquitoes will be 20,000.
We could use the numbers and the difference of the original cost - the end price in a equation.
53 × x/100 = 15.9
Cross multiply 100 × 15.9.
53x=1590
Divide both sides by 53.
x=30
The coupon was 30%
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft
Hope I helped :)
