This is a logistic growth model, so, we can set the function's differential equation equal to 0 and solve for p, then for y. So, let's take the derivative of this function and set it to 0:
\frac{dp}{dt} = 0.005p(300-p) = 1.5p-0.005p^2
\frac{d^2p}{dt^2} = 1.5 - 0.01p =0
-0.01p = -1.5
p = \frac{-1.5}{-0.01} = 150

Now, for a logistic model, the general solution is in the form of:
p = \frac{L}{1+Ce^{-ky}}
for
\frac{dp}{dt} = kp(L-p)

You haven't been given the 'C' constant, so I don't have a clue as to where to go after this. Sorry, we are yet to go over logistic growth in BC class. I could take you this far by just researching. If you have further questions, I'd be happy to answer them.

Please how to answer.

Answer:

Blue Rectangle: <u>135 mm²</u>

Blue Triangle: <u>45 mm²</u>

<em>Not sure if you need this but the </em>Total Square: <u>225 mm²</u>

Step-by-step explanation:

Area of a rectangle: <u>length x width</u>

Area of a triangle: \frac{1}{2}<u> x base x height</u>

First find the area of the blue rectangle.

Length = 15 mm

Width = 9 mm

Area = 135 mm²

Now find the area of the blue triangle:

Base = 6 mm (because the bottom is 15 total and you subtract the 9)

Height = 15 mm

Area = 45 mm²

Hope it helps!
