Answer:

z (max) =  17461.54  $

x₁   =  29.23 acres

x₂  =  0

x₃  =  3.07

Step-by-step explanation: INCOMPLETE QUESTION.

As the problem statement establishes:  "Each crop requires labor, fertilizer, and insecticide"  and information about quantities and availability does not exist. To build a model and that such model would be feasible I copy from the internet the following data. We assume the problem is to maximize the number of acres to plant with a maximum of profit ( we will use as profit the numbers 550  ;  350 ; 450 for  acres of corn, peanuts, and cotton)

Then z =  550*x₁  +  350*x₂  +  450*x₃    to maximize

                                            labor (h)      fertilizer ( tn)    Insecticide (Tn)

acres of corn         (x₁)               2                     4                        3

acres of peanut     (x₂)              3                     3                        2

acres of cotton      (x₃)              2                     1                         4

Availability         acres 40       120                120                      100

Constraints:

1) Size of the farm 120 acres

x₁  +  x₂   +   x₃   ≤   40

2) labor   120 h

2*x₁  +  3*x₂  +  2*x₃    ≤   120

3) Fertilizer  120 Tn

4*x₁  +  3*x₂  +  1*x₃      ≤   120

4) Insecticide 100 Tn

3*x₁   +  2*x₂  +  4*x₃     ≤  100

The Model is:

z =  550*x₁  +  350*x₂  +  450*x₃    to maximize

Subject to:

x₁  +  x₂   +   x₃   ≤   40

2*x₁  +  3*x₂  +  2*x₃    ≤   120

4*x₁  +  3*x₂  +  1*x₃      ≤   120

3*x₁   +  2*x₂  +  4*x₃     ≤  100

x₁    ≥   0  ;   x₂   ≥   0  ;   x₃   ≥   0

After 3 iterations using an on-line solver optimal solution is:

z (max) =  17461.54  $

x₁   =  29.23 acres

x₂  =  0

x₃  =  3.07

Answer:

$101

Step-by-step explanation:

Given

[tex]y = 8.50x + 33[/tex]

[tex]x \to[/tex] age above 40

Required

Insurance for 48 years old

First, we solve for x

[tex]x = 48 - 40[/tex]

[tex]x = 8[/tex]

So, we have:

[tex]y = 8.50x + 33[/tex]

[tex]y = 8.50 * 8 + 33[/tex]

[tex]y = 68 + 33[/tex]

[tex]y = 101[/tex]

Step-by-step explanation:

The volume of a hemisphere is given by :

[tex]V=\dfrac{2}{3}\pi r^3[/tex]

Taking differentiation,

[tex]\dfrac{dV}{dr}=2\pi r^2[/tex]

So,

[tex]dV=2\pi r^2\times dr[/tex]

Put r = 21 m and dr = 0.03 cm = 0.0003 m

[tex]dV=2\pi \times 21^2\times 0.0003\\\\dV=0.831\ m^3[/tex]

Hence, this is the required solution.

Answer:

x = 40

3x=120

x+40 = 120

Step-by-step explanation:

The angles are vertical angles which means they are equal

3x= x+80

Subtract x from each side

3x-x =x+80-x

2x = 80

Divide by 2

2x/2 = 80/2

x = 40

3x = 3(40) =120

x+80 = 40+80 = 120

Step-by-step explanation:

the answer is in the image above

The volume of the original cube is 1000 cubic units.

The volume of a cube is equal to the product of length, width and height of a cube.

Let the length of side of the original cube = L

The surface area of the original cube A₁ = 6 L²

When increase the side length of a certain cube by 4

The surface area of the increased cube A₂ = 6 (L + 4)²

The surface area increases by 576

So, 6(L + 4)² - 6 L² = 576

6(L² + 16 + 8L) - 6 L² = 576

Divided by 6 both the sides,

L² + 16 + 8L - L² = 96

16 + 8L = 96

8L = 96 - 16

8L = 80

L = 80/8

L = 10

So, the length of side of the original cube = L = 10 units

The volume of the original cube = L³

The volume of the original cube = (10)³

The volume of the original cube = 1000 cubic units

Step-by-step explanation:

that is the procedure above

The area of this circle with a radius of 13 inches is, C)530.66 inches

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

A circle with center A is given and the length of the line segment(radius),

AB = AD = AC = 13 inches.

We know, The area of a circle is,

= πr².

= π(13)² sq in.

= 530.66 sq in.

We can also find the perimeter or the circumference of the circle by the formula 2πr,

= 2π×13.

Given:

Principal = $14850

Rate of interest = 4% compounded semiannually.

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded and t is the number of years.

The interest is compounded semiannually, so n=2.

Putting [tex]P=14850, r=4, n=2, t=3[/tex] in the above formula, we get

[tex]A=14850\left(1+\dfrac{0.04}{2}\right)^{2(3)}[/tex]

[tex]A=14850\left(1+0.02\right)^{6}[/tex]

[tex]A=14850\left(1.02\right)^{6}[/tex]

On further simplification, we get

[tex]A=14850(1.12616242)[/tex]

[tex]A=16723.511937[/tex]

[tex]A\approx 16723.51[/tex]

Therefore, the amount in the account after three years is $16723.51.

Answer:

  12

Step-by-step explanation:

The square can be completed by adding and subtracting the square of half the linear term's coefficient.

  f(x) = x^2 -8x +(-8/2)^2 +28 -(-8/2)^2

  f(x) = (x^2 -8x +16) +(28 -16)

  f(x) = (x -4)^2 +12

The minimum value of the function is 12, when the squared term is zero.

If i'm wrong then my fault.

Step-by-step explanation:

When looking at choice (B) you can see it started at a decreasing point but slowly growing. Exponential relations are images or equations that describe growth and they always have the same function. If you look at the other choices you see that they either increase but then decrease or they don't match the formula for (exponential relations).

Answer:

Step-by-step explanation:

The importer needs to make the payment in the VND each time so the importer may enter into hedge to protect himself from the appreciation of the VND against the dollar, now if the importer enters into the forward contract of the hedge and he come across the reverse situation that means the VND is depriciating that means if the hedger would not have entered into a forward contract then they would have benefited more.

Lets convert above above rate in per VND rate to understand better.

E_USD/VND = 1/21000 = 0.000048

F_USD/VND = 0.000047

Ee_USD/VND = 0.000045

so as we can see above if we had enter into a hedge contract we have to pay the 0.000047 per VND and if we would not have enter into the contract we would have to pay the 0.000045 per VND hence cost of Hedging is 0.00002 USD per VND.
