We can conclude that the width of the rectangular ground is 19ft.
What is a rectangle?A quadrilateral with all of its angles equal, or right angles, is a rectangle.
In addition to having all equal angles, a square also has all equal sides. Therefore, a special case of a square is a rectangle.
To put it another way, a rectangle can also be a square.
So, we know that:
The perimeter of the rectangular ground is 90ft.
The length of the rectangular ground is 26ft.
Now, the width will be:
Perimeter of rectangle formula: P = 2(l+w)
Now, put the values and substitute as follows:
P = 2(l+w)
90 = 2(26+w)
90 = 52 + 2w
2w = 90 - 52
2w = 38
w = 38/2
w = 19ft
Therefore, we can conclude that the width of the rectangular ground is 19ft.

What is regression equation?
A regression equation is utilized in details to figure out what relationship, if any, exists between sets of information. For instance, assuming that you measure a kid's level consistently you could find that they develop around 3 inches a year. That pattern (growing three inches a year) can be displayed with a regression equation.
According to question:
The remarkable relapse condition is the dramatic capability that best fits the arrangement of information and it is given in the structure:
y = a · bˣ
where:
a = beginning worth of the model
b = remarkable develop or rot
x = time elapsed all along
For our situation,
y = 9.92 · (0.8208)ˣ
where:
a = 9.92
b = 0.8208
Since 0 < b < 1 we have an outstanding rot, affirming that the quantity of VHS is diminishing with time.
We can then utilize this condition to gather the quantity of VHS motion pictures in 2011.
As something first, compute how long all along (2000) would pass:
x = 2011 - 2000 = 11
Presently, substitute this worth in the situation:
y = 9.92 · (0.8208)¹¹
= 1.13
Thus, number of vhs movies in 2011 is 1.13 million.

What is the slope of a line parallel to the line whose equation is
8x-6y=-24
The slope of a line parallel to the line 8x - 6y = -24 is 4/3.
What is slope of a line parallel to the line whose equation is given?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation of the line.
8x - 6y = -24
First, rewrite in slope-intercept form.
8x - 6y = -24
Solve for y
8x + 24 = 6y
6y = 8x + 24
y = (8/6)x + 24/6
y = (4/3) + 4
Now, from the slope-intercept form;
y = mx + b
Where m is the slope
Slope of the line y = (4/3) + 4 will be
m = 4/3
All line parallel to the line y = (4/3) + 4 must have the same slope.
Hence, the slope of a parallel line to the line y = (4/3) + 4 will be;
m_parallel = 4/3
Therefore, the slope of the parallel line is 4/3.

A line that touches a curve at one point is said to be tangent. A point of tangency is the location where a curve and a line intersect. Y = mx + b is the slope-intercept formula for a line, where m is the line's slope. The straight line that "just touches" the curve at a particular location is referred to as the tangent line to a plane curve in geometry.

Tangent lineThe equation of the tangent line at x=1 can be written ...
y = g'(1)(x -1) +g(1)
The necessary function values are ...
g(1) = f(2·1 -6) = f(-4) = -3
and
g'(x) = f'(2x -6)·(2x -6)' = 2f'(2x -6)
g'(1) = 2f'(2·1 -6) = 2f'(-4) = 8

In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other forms of graphs.
A simple graph is one in which no two vertices are connected by more than one edge, and no edge begins or finishes at the same vertex. In other terms, a simple graph is one that doesn't have loops or many edges.
Reflection in the x axis will convert all positive values of f(x) to negative values of f(x) and vice versa.

What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = (f(x + h) - f(x)) /(x + h - x).
Its geometrical aspect is the slope of the tangent at a given point.
The given equation is y = 2x² + 4x - 6.
The vertex is a point at the graph where the slope becomes zero. It can be found by equating the differentiation of the equation to zero as below,
y = 2x² + 4x - 6
=> y' = 4x + 4 = 0
=> x = -1
At x = -1 the value of y can be found as,
y = 2 × -1² + 4 × -1 - 6
= 2 - 4 - 6
= -8
Thus, the vertex is given as (-1, -8) which is only valid for option (b).
