A rectangular rose garden of length 15 m and width 9 m is surrounded by a path of width 1.2m. find the distance around the outside of the path
The perimeter of the rectangular rose garden distance outside the path is 57.6m.
What is perimeter of the rectangle?Two equal lengths and two equal widths make up a rectangle. We must sum up the lengths of the rectangle's four sides in order to get its perimeter.
Since there are two of each side length, it is easy to accomplish this by simply adding the length and width and multiplying the result by two.
Perimeter = 2(length + breadth)
Calculation for the outside of the path.
Th initial length of park is 15m.
The increment of the length after the width of path is included is;
= 15 + 1.2 + 1.2 (for both side)
= 17.4m
Similarly, the initial width of the park is 9m.
After the increment of the path the width becomes,
= 9 + 1.2 + 1.2 (both side included)
= 11.4m
The perimeter of the rose garden is ;
P = 2( 17.4 + 11.4)
= 2×28.8
= 57.6m
Therefore, the rectangular rose garden has the perimeter of 57.6m.

Prove: ∠2 = ∠3
The statement "If ∠1 and ∠2 form a linear pair; ∠1 and ∠3 are supplementary, then ∠2 = ∠3" is proved.
If the sum of two angles is 180 then they are called supplmentary angles of each other.
If one straight line meets another straight line at a point, then two adjoint angles at that point on that line is called Linear angles to each other.
Here given that ∠1 and ∠2 are linear to each other.
From property of the linear angles we know that the sum of linear angles is 180.
Therefore, ∠1 + ∠2 = 180
So, ∠2 = 180 - ∠1 .........(1)
Also it is given that, ∠1 and ∠3 are supplementary angles.
So, ∠1 + ∠3 = 180
Therefore, ∠3 = 180 - ∠1.....(2)
Comparing (1) and (2) we get,
∠2 = ∠3 = 180 - ∠1

Let's bring both equations to slope-intercept form. Then we can think about the slopes and the y-intercepts of the lines represented by each equation.
The slope-intercept form of the first equation 2y=4x+62y=4x+62, y, equals, 4, x, plus, 6 is y=2x+3y=2x+3y, equals, 2, x, plus, 3. The second equation y = 2x+6y=2x+6y, equals, 2, x, plus, 6 is already in slope-intercept form.
Hint #22 / 3
The first equation is y = 2x+3y=2x+3y, equals, 2, x, plus, 3, so the slope of its line is 222 and the yyy-intercept is (0,3)(0,3)left parenthesis, 0, comma, 3, right parenthesis.
The second equation is y = 2x+6y=2x+6y, equals, 2, x, plus, 6, so the slope of its line is 222 and the yyy-intercept is (0,6)(0,6)left parenthesis, 0, comma, 6, right parenthesis.
Since both lines have the same slopes but different yyy-intercepts, they are distinct parallel lines.
Hint #33 / 3
Since distinct parallel lines don't intersect, we conclude that the system has no solutions.

The slope is 2.
The slope is One-half.
The y-intercept is –4.
The y-intercept is 8.
The points (–2, –5) and (8, 0) are also on the line.
The points (–5, –2) and (1, 10) are also on the line.
The equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form is y = 50. Hence, 4th option is the right choice.
The slope-intercept form of a line is written as y = mx + b, where m is the slope of the line, and b is the y-intercept.
The slope of a line passing through the points (x₁, y₁) and (x₂, y₂) can be calculated using the formula, slope (m) = (y₂ - y₁)/(x₂ - x₁).
Therefore, slope of the line passing through the points (-25, 50) and (25, 50) can be calculated as m = (50 - 50)/(25 - (-25)) = 0/(-50) = 0.
We can find the equation of the line using the point-slope formula, according to which, a line having a slope m and passing through the point (x₁, y₁) can be written as y - y₁ = m(x - x₁).
Therefore, the equation of the given line can be written as:
y - 50 = 0(x - 25)
or, y - 50 = 0,
or, y = 50.
Therefore, the equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form is y = 50. Hence, 4th option is the right choice.

What are mathematics operations?
• A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Here, the given fractions are :
1/9 and 2/9
clearly 2/9 is twice the value of fraction 1/9.

What is a trigonometric function?Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trig functions.
the difference in y values from max to min = 15. 15/2 = a
max cosine = 1, min cosine =-1
7.5 x 1 - 1.5 = 6
7.5x -1 -1.5 = -7.5-1.5= -9
h(x) = 7.5cos(bx+c) -1.5
now just get a period or frequency that matches the x coordinates 3 and 6.5 to get b and c
at (3,6) cosine = 1 to get a maximum value. cosine is at a max when cos(bx+c) = 1 and bx+c=0, 360, 720...
if x=3, then 3b +c=0 and c=-3b
for (6.5,-9) to be a minimum h value, then cos(6.5b+c) =-1 that happens when the angle = 180. +n360 for any integer n. 6.5b+c = 180
c= 180-6.5b
c=-3b
180-6.5b =-3b
add 6.5b to both sides to get
180= 3.5b
b = 180/3.5 = 51 1/7
c=-3b = -153 3/7
h(x) = 7.5cos(51.4x - 154.3)-1.5
