An orange grove produces a profit of $ 100 per tree when there are 1300 trees planted. Because of​ overcrowding, the profit per

tree​ (for every tree in the​ grove) is reduced by 4 cents per tree for each one additional tree planted. How many trees should be planted in order to maximize the total profit of the orange​ grove? What is the maximum​ profit? How many trees should be planted in order to maximize the total profit of the orange​ grove?

Answer:

Step-by-step explanation:

(x) = (1100 + x) (100 - .05(x-1100))

This is a quadratic, graphs as a parabola that opens downward. A maximum cam be found.

The zeros of the function are

(1100 + x) = 0 ..... or ..... [100 - .05(x-1100)] = 0

x = -1100 is the left x-intercept.

[100 - .05(x-1100)] = 0

100 = .05(x-1100)

2000 = x - 1100

x = 3100 is the right intercept.

Maximization of profits is at the mid point of the zeros (x-intercepts)

(3100 + -1100)/2 = 1000

1100 + 1000 = 2100 trees should be planted to maximize profits.

f(x) = (1100 + 1000) (100 - .05(1000-1100))

f(x) = (2000) (105) = 220,500 is the maximum profit.

I hope this helps!

snow_tiger [21]

Answer:

Cost of the 5 pounds of  Ashmend’s kernel apples is $7.5

Step-by-step explanation:

As given

At a local farmer’s market , Jodi bought 3 pounds of Ashmead’s kernel Apples for $4.47 at the McDougal Orchards stand .

i.e

3 pounds = $ 4.47

Now find out the cost of 1 pound of Ashmend kernel apples .

The\ cost\ of\ 1\ pound\ of\ Ashmend\ kernel\ apples = \frac{4.47}{3}

                                                                         = $ 1.5 (Approx)

Cost of  5 pounds of Ashmend’s kernel apples = Amount of apples × Cost of 1 pounds of apples .

                                                                              = 5 × 1.5

                                                                              = $ 7.5

Therefore the cost of the 5 pounds of  Ashmend’s kernel apples is $7.5 .

Write the equation of a line through (3,1), parallel to y = x + 1
Vera_Pavlovna [14]

Answer:

The answer is C ( y= 2/3x - 1 )

Step-by-step explanation:

Equation Formula : y - y1 = m ( x - x1)

y - 1 = 2/3 ( x - 3 )

y - 1 = 2/3x - 2

y = 2/3x - 2 + 1

y = 2/3x - 1

16x^2 - 49 when factored is ?
vaieri [72.5K]

Answer:

(4x-7)(4x+7)

Step-by-step explanation:

This is called the Difference of Two Squares (DOTS).

These are the conditions that must be met for DOTS to work:

•There must be 2 terms.

•They must be separated by a negative sign.

•Each term must be a perfect square.

First, you have to find 2 square numbers that times together to make 16.

4×4=16

As we want 16x², you just need to make the 4 become 4x:

4x times 4x equals 16x²

Then, find 2 squares that times together to make 49.

7×7=49

You can put the two squares into a bracket with the x variable first, then the number:

(4x-7)(4x+7)

In the brackets, you always put the negative sign in the first one and then the plus sign in the second one.

You can double check your answer by expanding it back out again using FOIL:

F-First

O-Outer

I-Inner

L-Last

Times the First two in the two brackets:

4x times 4x equals 16x²

Times the Outer two:

4x times 7 equals 28x

Times the Inner two:

-7 times 4x equals -28x

Times the Last two:

-7 times 7 equals -49

Form an equation:

16x²+28x-28x-49

The 28x cancel out to leave:

16x²-49

Hope this helps :)
