A population of rabbits at time t increases at a rate of 40-12t+3t^2 rabbits per year where t is measured in years. Find the po

zmey [24]

We have to find derivative of t

$\\ \sf\longmapsto \dfrac{d}{dx}3t^2-12t+4$

$\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}$

$\\ \sf\longmapsto \dfrac{d}{dx}3t^2-\dfrac{d}{dx}12t+\dfrac{d}{dx}40$

$\\ \sf\longmapsto 6t-12$

Now

t=8..

$\\ \sf\longmapsto 6(8)-12$

$\\ \sf\longmapsto 48-12$

$\\ \sf\longmapsto 36$

Anton [14]

Answer: there are 59059 lbs of gravel.

Step-by-step explanation:

In a mixture of concrete, there are four lbs of cement mix for each pound of gravel. This means that eight lbs of cement would be mixed for 2 pounds of gravel and 12 lbs of cement would be mixed for 3 pounds of gravel and 12. Therefore, the constant ratio of cement to gravel is 4:1

The total ratio is 4 + 1 = 5

If the mixture contains a total of 295295 lb of these two ingredients, then the number of pounds of gravel that are there is

1/5 × 295295 = 59059 lbs
