So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches
the square area is 4x4 is 16
each semicircle has a diameter of 4cm.
area of a semicircle is pi * r^2/2
3.14*2^2/2=6.28
since there are 45 sides of a square, 6.28x3=18.84
add 18.84 and 16.
34.84 is your answer.
More. 6x5/7=4 2/7 which is more than 5/7.
A logistic differential equation can be written as follows:
![\frac{dP}{dt} = rP[1- \frac{P}{K}]](https://tex.z-dn.net/?f=%20%5Cfrac%7BdP%7D%7Bdt%7D%20%3D%20rP%5B1-%20%5Cfrac%7BP%7D%7BK%7D%5D%20)
where r = growth parameter and K = carrying parameter.
In order to write you equation in this form, you have to regroup 2:
![\frac{dP}{dt} = 2P[1- \frac{P}{10000}]](https://tex.z-dn.net/?f=%20%5Cfrac%7BdP%7D%7Bdt%7D%20%3D%202P%5B1-%20%5Cfrac%7BP%7D%7B10000%7D%5D%20)
Therefore, in you case r = 2 and K = 10000
To solve the logistic differential equation you need to solve:
![\int { \frac{1}{[P(1- \frac{P}{K})] } } \, dP = \int {r} \, dt](https://tex.z-dn.net/?f=%20%5Cint%20%7B%20%5Cfrac%7B1%7D%7B%5BP%281-%20%5Cfrac%7BP%7D%7BK%7D%29%5D%20%7D%20%7D%20%5C%2C%20dP%20%3D%20%20%5Cint%20%7Br%7D%20%5C%2C%20dt%20%20)
The soution will be:
P(t) =

where P(0) is the initial population.
In your case, you'll have:
P(t) = <span>

Now you have to calculate the limit of P(t).
We know that
</span>

hence,

<span>

Answer:
Step-by-step explanation:
total sold amount= 1200+1350=2550
profit amount on first radio= 1200-(1200/1.2)=1000
purchase amount of 1st radio= Rs. 1000
total purchased amount= (2550/1.02) = Rs. 2500
purchase amount of second radio= 2500 - 1000 = Rs. 1500
loss % on second radio= ((1500-1350)/1500 ) * 100 = 10%
