The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.
What is a rectangle?A rectangle is a type of parallelogram that has equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
The dimensions of the given rectangle are (650 - 2x) and x.
Then, the area of the given rectangle can be written in terms of x as
A(x) = x(650 - 2x)
In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,
(660 - 2x) - 2x = 0
=> 4x = 660
=> x = 660 / 4
=> x = 115
Now, the maximum area is the value of A(x) at x = 115 as below,
= 115 × (650 - 2×115)
= 115 × 320
= 36800
The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.
Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

Step-by-step explanation:
Passes through the x-intercept of 2x - 3y = 6 and parallel to x + 4y = -3
The equation of the line passes through the x intercept of 2x - 3y = 6 and parallel to x + 4y = -3 is y = (-1/4)x + 3/4 .
In the question ,
it is given that ,
the required line is parallel to x + 4y = -3 ,
x + 4y = -3
4y = -x -3
dividing both sides by 4 , we get
y = (-1/4)x -3/4
the slope is -1/4 .
the required line passes through the x intercept of 2x - 3y = 6 .
for x intercept , put y=0 ,
we get
2x -3(0) = 6
2x = 6
x = 6/2
x = 3
the point is (3,0) .
The equation of the line passing through the point (3,0) and the slope -1/4 is
(y-0) = (-1/4)(x-3)
y = -1/4(x - 3)
y = (-1/4)x + 3/4
Therefore , the equation of the line passes through the x intercept of 2x - 3y = 6 and parallel to x + 4y = -3 is y = (-1/4)x + 3/4 .

I graphed a parallelogram. Now I need to show that the diagonals bisect each other, or have the same midpoint. What does this mean?
A biscetor is a line that curs another one exactrly at its midpoint. If the diagonals of the paallelogram bisect each other, this means that both cut the other in exact halves.
For example
For the square ABCD, its diagonals BD and AC cut each other in point M.
M is their midpoint, which means that the haves of each diagonal are the same:
For diagonal AC you get that AM=MC
For diagonal BD you get that BM=MD
This means that the diagonals bisect each other and have the same midpoint M

Part B: If the parent function f(x) = |x| is transformed to h(x) = |x| − 2, what transformation occurs from f(x) to h(x)? How are the vertex and range of h(x) affected?
The required solutions are as follows,
(a) Vertex, domain, and range of the given function is (0,3), the domain is all real numbers and the range is all real value greater than +3 respectively.
(b) The trasformation shifts the f(x) two units below and vertex and range are (0, -2) and all real values greater and equal to -2 respectively.
here,
(A)
f(x) = |x - 3|
put x= 0
f(x) = 3
So the vertex is (0, 3)
Absolute functions has a domain of all real numbers, while the range of the given function is from positive 3 to infinity because the minimum value of the function is 3.
Similarly
(b)
f(x) = |x|
Vertex = (0, 0)

complementary angles. If m/A= (5x - 11)° and
ZA and ZB are
m/B = (6x + 2)°, then find the measure of ZA.
PLEASE ANSWER ASAP !!!!
Answer:
∠ A = 34°
Step-by-step explanation:
complementary angles sum to 90° , then
5x - 11 + 6x + 2 = 90
11x - 9 = 90 ( add 9 to both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
∠ A = 5x - 11 = 5(9) - 11 = 45 - 11 = 34°

A plane traveled 1160 kilometers to Havana and back.
The trip there was with the wind. It took 10 hours.
The trip back was into the wind. The trip back took 20 hours.
What is speed, distance, and time?
The formula speed distance time is used to explain the relationship between speed, distance, and time. That is speed = time/distance. To put it another way, distance divided by speed equals time. You can figure out the third input if you know the first two.
Consider,
s = plane speed in still air
w = speed of the wind
then
(s+w) = ground speed with the wind
and
(s-w) = ground speed against the wind:
A dist equation for each way (dist = speed * time)
10(s+w) = 1160
20(s-w) = 1160
Simplify divide the 1st equation by 13, and the 2nd equation by 26, and you have:
s + w = 116
s - w = 58
Using adding s & eliminates w,
2s = 174
s = 174/2
s = 87 km plane speed in still air
The wind speed
87 + w = 96
w = 9 km is the wind speed
Hence, the speed of the plane in still air is 87 kilometers, and the speed of the wind is 87 kilometers.

The equation has 2 irrational roots and two real distinct solutions.
What is a real distinct solution?It is a solution to an equation that occurs only once and differs in value from other solutions. If the discriminant is zero, there are no real solutions. The discriminant equation is Δ = b² - 4ac. If the discriminant is greater than zero it has two irrational roots. Another alternative for a distinct solution is the coincident solution. The values of the discriminant show how many roots and solutions the equation may contain.
