A farmer purchased 480 meters of fencing, and will build a rectangular pen with it. To enclose the largest possible area, what should the
pen's length and width be? Model the pen's area with a function, and then find its maximum value.

To enclose the largest possible area, the pen's length should be__and width should be__.

Answers

Answer 1

The largest possible area will be 14400 meters², the pen's length should be 120 meters, and the width should be 120 meters.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

Let's assume that the length of the pen would be x.

We have been given the perimeter as 480 meters.

Let w be the width of the rectangle  and l be the length of the rectangle

The perimeter of a rectangle = 2(l+w)

So, 480= 2(x + w)

240 = x + w

w = 240 - x

Length = x and width = (240 – x)

Area = x(240 - x) = 240x - x²

To get the maximum area, we equate the first derivative of the area to zero.

A = 240x - x²dA/dx = 240 - 2x = 0

2x = 240

x = 120

So, width = 240 – x = 240 – 120 = 120.

Maximum area = length × width

Maximum area = 120 × 120 = 14400 meters²

Thus, the pen should be 120 meters long and 120 meters wide, with a maximum possible area of 14400 meters².

What is dilation?

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.

How to determine the image of the scaled copy of the square?

From the question, we have the following parameters that can be used in our computation:

Square MNOP with vertices M(-7,-4), N(-4,-3), O(-3, -6), and P(-6, -7): Scale factor of dilation, k = 2

This means that

Scaled copy = Scale factor * Vertices of MNOP

So, we have

M'N'O'P' =M(-7,-4), N(-4,-3), O(-3, -6), and P(-6, -7)* 2

Evaluate

M'N'O'P' =M'(-14,-8), N'(-8,-6), O'(-6, -12), and P'(-12, -14)

Answer:

Step-by-step explanation:

The sum S of the interior angles of a regular polygon is given by the formula

S = (n-2) x 180 where n is the number sides

Here n = 9

So S = (9-2) x 180 = 7 x 180 = 1,260

There are 9 interior angles and each angle is (5z + 65)

So the sum of all 9 interior angles = 9 (5z + 65)

= 45z + 585

Set these equal to each other and solve for z

45z + 585 = 1260

45z = 675

z = 675/45 = 15

Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

The y-value of the lowest point of the curve is just above y = -2.The y-value of the highest point of the curve is more than y = 3.

Therefore, the most appropriate range from the given answer options is:

y > -2

Note:  The graph appears to be the exponential function  [tex]y=2^x-2[/tex]  with a horizontal asymptote at y = -2.  This means that the curve will get closer and closer to y = -2 as x approaches negative infinity, but it will never touch it.  The function approaches infinity as x approaches infinity.  Therefore, the range for this function is y > -2

An orchard has 468 pear trees. The number of rows exceeds the number of trees per row by 8. How many trees are there in each row

Answers

If an orchard has 468 pear trees and The number of rows exceeds the number of trees per row by 8. the number of trees that are in each row would be 18

How to solve for the number of trees

We have to define T as the number of trees that are in a row.

Then we have to define t + 8 as the number of rows that we have

This would give us the equation that is written as

t(t + 8) = 468

then we would have

t² + 8t -468 = 0

We would have to find the factors of 468 which when inputted in the equation would give us the value 468

t(t + 8) = 468

This factor would be 18

such that

18 ( 18 + 8) = 468

18 * 26 = 468

468 = 468

Hence the number of trees that are in each row would be 18

If an arrow is shot straight upward on the surface of the moon with initial velocity 60m/s, its height after t seconds is given by h(t) = 60t - 0.8t². (a) What is the velocity of the arrow after 1 second? (b) At what time t > 0 will the arrow hit the moon? (c) What is the velocity of the arrow when it hits the moon? (d) At what time does the arrow reach its maximal height?​ Show your working out!

Answers

The motion of the arrow, described by the kinematic equation for the height, h(t) = 60·t - 0.8·t² are as follows;

(a) The velocity after 1 second is 58.4 m/s

(b)  The arrow hits the moon after 75 seconds

(c) The velocity of the arrow when it hits the moon is 60 m/s

(d) The arrow reaches the maximum height  in37.5 seconds.

What is a kinematic equation?

A kinematic equation is an equation that describes the motion of an object moving under constant acceleration.

The kinematic (equation) function for the height of the arrow is; h(t) = 60·t - 0.8·t²

The initial velocity of the arrow = 60 m/s

(a) The velocity of the arrow = The rate of change of the height, therefore;

v = h'(t) = 60 - 2 × 0.8·t = 60 - 1.6·t

The velocity after 1 second = h'(1) = 60 - 1.6 × 1 = 58.4

The velocity of the arrow after 1 second is 58.4 m/s

(b) When the arrow hits the moon, we get;

h(t) = 0, therefore;

h(t) = 60·t - 0.8·t² = 0

( 60 - 0.8·t)·t = 0

t =  0  or 60 - 0.8·t = 0

t = 60/0.8 = 75

The time the arrow hit the moon is 75 seconds after being shot

(c) The velocity of the arrow when it hits the moon is  found using the equation;

h'(37.5) = 1.6 × 37.5 = 60

The velocity when it hits the moon, the velocity is 60 m/s

(d) The motion of the arrow is symmetrical, therefore, the time it takes the arrow to reach the the maximal height is the time it takes the arrow to reach back to the moon surface, which indicates;

The time it takes the arrow to reach maximum height is half the time it takes the arrow to hit the moon after being shot = 75/2 seconds = 37.5 seconds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be = $ 375

Let the total number of bills = 24

Let the number of $ 5 bills be = x

Let the number of $ 10 bills be = y

Let the number of $ 20 bills be = z

The total number of $ 5 bills x = ( 1/2 ) x number of $ 10 bills

So , x = y/2

Now , the equation will be

The total number of bills = x + y + z

So , x + y + z = 24   be equation (1)

And ,

The total amount = 5x + 10y + 20z

So , 5x + 10y + 20z = 375

Divide by 5 on both sides , we get

x + 2y + 4z = 75   be equation (2)

On simplifying equation (1) and equation (2) , we get

x + y + z = 24

Substituting the value of y , we get

x + 2x + z = 24

3x + z = 24   be equation (3)

And ,

x + 2y + 4z = 75

x + 4x + 4z = 75

5x + 4z = 75   be equation (4)

Multiply equation (3) with 4 , we get

12x + 4z = 96   be equation (5)

Subtract equation (4) from equation (5) , we get

7x = 21

Divide by 7 on both sides , we get

x = 3

Therefore , the number of $ 5 bills is 3

Substitute the value of x , we get

y = 2x

y = 6

Therefore , the number of $ 10 bills is 6

Substitute the value for x and y in equation (1) , we get

x + y + z = 24

3 + 6 + z = 24

z + 9 = 24

Subtract 9 on both sides , we get

z = 15

Therefore , the number of $ 20 bills is 15

Hence ,

The number of $ 5 bills = 3

The number of $ 10 bills = 6

The number of $ 20 bills = 15

Then the inner integral in this problem is given as follows:

We are integrating the variable x, then the variable y is a constant, as thus the result is given as follows:

I = 1.5x² + xy, from x = -4 to x = 2.

Then, applying the Fundamental Theorem of Calculus, the result is given as follows:

I = 1.5(2)² + 2y - 1.5(-4)² + 4y = 6y - 18.

Then the outer integral is calculated as follows:

[tex]O = \int_{-4}^{2} 6y - 18[/tex]

Then the result is given as follows:

O = y² - 18y, from y = -4 to y = 2.
