Answer:
900 square meters
Step-by-step explanation:
The property is in the shape of a square.
The perimeter of a square is given as:
P = 4L
where L = length of its side
Therefore, the length of the property is:
120 = 4 * L
L = 120 / 4 = 30 meters
The area of a square is given as:
A = L * L
Therefore, the area of the property is:
A = 30 * 30 = 900 square meters
Let the number be y.
One third of y = (1/3)*y = y/3
This is decreased by 6; y/3 - 6
And it equals 8
That means:
y/3 - 6 = 8
y/3 = 8 + 6
y/3 = 14
y = 3*14
y = 42
The number is 42.
I hope this helps.
The slope-intercept form of the equation of the line described is y + 2x = 4.
What are parallel lines?
Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.
Given:
The line is parallel y = -2x - 5
Therefore they have equal slope
From the equation y = -2x - 5
the slope m is -2
Given point = (4,-4)
Therefore the slope-intercept form
y - y1 = m ( x - x1 )
=> y + 4 = -2 ( x - 4)
=> y + 2x = 4

Equation of a tangent line of a curve is:
y- y0 = f´ (x0) (x - x0 ). In this case: x0=1, y0=1
f´(x)=
(Derivation)
f´(x0)=
y - 1 = 1/2 ( x - 1 )
y - 1 = 1/2 x - 1/2
y = 1/2 x - 1/2 + 1
y =
