The lengths of the sides of the rectangular field in order to minimize the cost will be length = 6000 feet and width = 4000 feet .
In the question ,
it is given that ,
the area that farmer need to fence = 24 million square feet
let the length of field be [tex]=[/tex]"x" and
let the width of rectangular field be [tex]=[/tex]"y" .
So , the area of the rectangular field = x.y = 24
So , y = 24/x .
given that the field is divided into half ,
So , the required fencing will be
S = 2x + 3y
Substituting y = 24/x in the equation,
we get ,
S = 2x + 3(24/x)
S = 2 + 72/x
Differentiating the equation "S [tex]=[/tex] 2 [tex]+[/tex] 72/x" with respect to "x" ,
dS/dx = 2 - 72/x²
to minimize the cost of fencing , we equate ds/dx to 0 ,
we get
2 - 72/x² = 0
x² = 36 million feet
x² = 36000000
x = 6000 feet
and y = 24/x = 24million/6000
= 24000000/6000
= 4000 feet
Therefore , The length of the rectangular field is 6000 feet and the width of the rectangular field is 4000 feet .

Write a linear equation to represent the hours that Yuson has left to do after x days.
The linear equation to represent the hours that Yuson has left to do after x days is 16 - 2x.
How to calculate the equation?From the information, Yuson has to do Y hours of community service.
She works two hours every day, so service hours in x days = 2x
Remaining service hours after x days = y-2x

Alice changes size several times. The ratio of her orginal height to her second height is 24 to 5. The ratio of her second height ot he rthird height is 1 to 12. The ratio of her orginal height to her fourth height is 16 to 1. The tallest of these four heights is 10 feet. What is her shortest height?
Answer:
3 inches
Step-by-step explanation:
Let's call the heights H1 thru H4.
So we have
H1/H2 = 24/5
H2/H3 = 1/12
Therefore if we multiply these, we have
H1/H3 = 2/5
Finally we are given
H1/H4 = 16/1.
By logic we can see that H3 is the tallest.
Thus if H3 = 10 feet, H1 = 4 feet
And from that,
H2 = 1/12 (10 feet) = 5/6 feet = 10 inches
and finally
H4 = 1/16(H1) = 1/16(4 feet) = 1/4 foot =
3 inches
Answer:
3 inches
Step-by-step explanation:
Let's call the heights H1 - H4
Here, we have
H1/H2 = 24/5
H2/H3 = 1/12
And so, we have
H1/H3 = 2/5
Finally
H1/H4 = 16/1.
Thus if H3 = 10 feet, H1 = 4 feet
And from that,
H2 = 1/12 (10 feet) = 5/6 feet = 10 inches
And last,
H4 = 1/16(H1) = 1/16(4 feet) = 1/4 foot = 3 inches
the equation of the curve is y = x^2 + ax + b. The points (0,-5) and (5,0) lie on the curve. Find the coordinates of the turning point of the curve.
The turning point of the parabola is the point (2, - 9).
What is the turning point of a quadratic equation?
Quadratic equations represents parabolae and the vertex of the parabola represents the turning point as the slope of the curve changes its sign, from positive to negative or viceversa. The vertex can be derived by the vertex form of the equation of the parabola:
y - k = C · (x - h)²
Where:
(h, k) - Coordinates of the vertex.C - Vertex constantSince the quadratic equation has two real coefficients, we need the location of two points on Cartesian plane to find one solution. First, create the system of linear equations:
b = - 5 (1)
5 · a + b = - 25 (2)
Second, substitute b in (2) and clear a:
5 · a - 5 = - 25
5 · a = - 20
a = - 4
Third, write the quadratic equation:
y = x² - 4 · x - 5
Fourth, transform the equation into vertex form by completing the square:
y + 9 = x² - 4 · x + 4
y + 9 = (x - 2)²
Fifth, write the vertex of the parabola:
(h, k) = (2, - 9)
The point (2, - 9) represents the turning point of the parabola.

Graph the piecewise function.
(6 points - 2 points for each piece)
Points of interval A (-1,-3) and (-2,-6)
Points of interval B is (1,1) and (2,-1)
How to find Piecewise function?
Determine which of the following intervals (or inequalities) the input belongs to before evaluating a piecewise function at any given input. The function specification for that specific interval can then simply be updated to reflect the new input.
[tex]f(x)=\left \{ {{3x, if x\leq -1} \atop {-2x+3, if 0 < x < 4}}\atop {2, if x\geq 4}\right.[/tex]
lets take 3x as Interval A
-2x+3 as interval B
and 2 as interval C
Now lets calculate the interval A
f(x)=3x
as x≤-1
∴f(-1) = 3(-1)
=(-3)
∴ point is (-1,-3)
∴f(-2) = 3(-2)
=(-6)
∴ point is (-2,-6)
Now lets calculate the interval B
f(x)=-2x+3
as 0<x<4
∴f(1) = -2(1)+3
=-2+3
=1
∴ point is (1,1)
∴f(2) = -2(2)+3
=-4+3
= -1
∴ point is (2,-1)

Which is greater -2/5 or -3/8 ?
Answer:-2/5
Step-by-step explanation: due to them being negative we are using the simple thing of which number is closer to zero. -2/5 is closer which means that is it greater. -2/5 would be ahead on number line if you need a visualization
Answer:
-3/8
Step-by-step explanation:
1) Work out the options you are given
-2/5 = -0.4-3/8 = -0.3752) Find which one is greater
As the numbers are decimal the 'seemingly greater number' might actually be the smaller one.
To find out which decimal is greater you can easily plot them into a number line.
The number that is further to the left is smaller and the number closer to the right is higher!
If we were to plot the numbers one a number line the -0.375 would be closer to the right meaning it is greater.
HINTS:
To make it easier to divide minus numbers, at first completely forget about the minus (you can plug it back in at the end).
For example, if you were given -2/5 get rid of the minus to get 2/5 and from this we can easily figure out 2 ÷ 5 which would give us 0.4.
At the point where you have your final number you can add the - back in making it -0.4

Find the equation of the line passing through the given point and parallel to the given line.

(-5, -2), y + 3x = 10
The equation of the lines passing the points and parallel to the equations ( 7,-3) , 3y = 12x + 5 (-5, -2), y + 3x = 10 is as follows:
y = 4x - 31y = -3x - 17.How to find the equation of a line?The equation of a line can be represented in different form such as standard form, general form, slope intercept form and point slope form. Therefore, let's represent the line in slope intercept form.
The equation of a line in slope intercept form is as follows:
y = mx + b
where
m = slopeb = y-interceptParallel line shave the same slope.
Hence,
( 7,-3) , 3y = 12x + 5
y = 4x + 5 / 3
slope is 4
The equation of the line is y = 4x + b. let's find the y-intercept using (7, -3).
-3 = 4(7) + b
b = -3 - 28
b = - 31
Hence, y = 4x - 31
(-5, -2), y + 3x = 10
y = -3x + 10
slope = -3
Therefore, let's find y-intercept using (-5, -2)
-2 = -3(-5) + b
-2 = 15 + b
b = -2 -15
b = - 17
Therefore, y = -3x - 17.

Without calculating, order the quotients smallest to largest.
The order of the quotient from smallest to largest is given as follows:
42.6/70, 426/70, 42.6/0.07, 42.6/0.07.
What is a quotient?A quotient is given by the division of two terms a and b, that is:
a / b.
From this, we have that the dividend a and divisor b are inverse proportional, that is:
A large quotient is achieved when a is large and b is small.A small quotient is achieved when a is small and b is large.There are three divisions with the same term a, hence they are ordered, from smallest to largest, as follows:
42.6/70, 42.6/0.07, 42.6/0.07.
(the smallest the value of b, the largest the quotient).
The final quotient is:
426/70.
Dividing by 10 to have an equivalent value of a, we have that:
426/70 = 42.6/7.
Which is the second largest value of b, hence the second smallest quotient.
