A farmer finds that if she plants 100 trees per acre, each tree will yield 35 bushels of fruit. She estimates that for each addi

castortr0y [4]

Answer:

126 trees should she plant per acre to maximize her harvest.

Step-by-step explanation:

Let x be the additional tress that must be plant after planting 100 tress.

So, total number of trees = 100 + x trees

Also, Each additional tree planted decreases the yield of each tree by 3 bushels.

So , net bushels by each tree = 35 - 3x

The revenue function becomes

f(x) = (100 + x)(35 - 3x)

Thus,

Differentiating it by using chain rule as:

f'(x) = (100 + x)35 + 100(35 - 3x)

f'(x) = 3500 + 35x + 3500 - 300x

f'(x) = 7000 - 265x

For maxima of f(x), f'(x) = 0

7000 - 265x = 0

Thus,

x = 26.4151

Since, x represents tress, so, x is 26.

So, total tress she would plant to earn maximum revenue = 100 + 26 = 126 trees

The length of a rectangle is five times its width.

Marizza181 [45]

ANSWER

96 yd

EXPLANATION

Let the width of the rectangle be w, then, the length of the rectangle will be:

$l = 5w$

The area of a rectangle is calculated using the formula:

$Area=l \times w$

$Area=5w \times w$

$Area=5 {w}^{2}$

It was given that, the area of the rectangle is 320yd²

$320=5 {w}^{2}$

Divide both sides by 5.

$64 = {w}^{2}$

Take square root of both sides to get:

$w = 8yd$

This means the length is

$l = 5 \times 8 = 40yd$

The perimeter of a rectangle is given by:

P=2(w+l)

We plug in the values to get:

$P=2(40 + 8) = 2 \times 48 = 96yd$

The perimeter is 96yd
