Answer:

A dependent variable is a variable (often denoted by y ) whose value depends on that of another.  so it is the variable that changes depending on the numbers beside it.

Elanso [62]

Let the lenght perpendicular to street = x

Means lenght two sides will be x and x

Another side of retangle will be = 256 - 2x

Area of rectangle will be= A = x * (256-2x) = 256 x - 2 x^2

For maximum area, dA/dx = 0

d/dx (256 x - 2 x^2) = 0

256 - 4 x = 0

4 x = 256

x = 64 feet

Means one side is 64 feet

Another side will be = 256 - 2 * 64 = 128

Now we have two sides of rectangle 64 and 128

Area = 128 * 64 = 8192 square feet : Answer

Hope it will help :)

A population of 50 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 500 deer.
rewona [7]

Answer:

p1 = 70 deer

p2 = 98 deer

Step-by-step explanation:

We use the population growth expression:

N(t)=N_0\,(1+r)^t

which in our case renders:

N(t)=N_0\,(1+r)^t\\N(t)=50\,(1+0.4) ^t\\N(t)=50\,(1.4) ^t

Therefore, after 1 year the population would be:

N(1)=50\,(1.4) ^1=70

giving a total of 70 deer

and after two years, it would be:

N(2)=50\,(1.4) ^2=98
