The missing number in a given integer array of 1 to 100 can be found using the PHP array_diff() function.

This function compares two array and returns the difference. To find the missing number, we first need to create an array that contains all numbers from 1 to 100. We then create another array with the given integers. Using array_diff(), we can compare the two arrays and the difference will be the missing number.

To use the array_diff() function, we first need to create the two arrays. For example,

$array1 = range(1,100);

$array2 = array(1,2,3,4,5,6,7,8,9);

The first array is containing all numbers between 1 and 100 and the second array is containing the given integers.

The next step is to use the array_diff() function. The syntax for this is

The result of this will be an array containing the missing integer.

The length of the rectangular  playground is 241.86 foot.

Given that area of rectangle is 19,500 sq.ft and length of rectangle is three times its width.The area for rectangle is given by formula: A=LW.

Now according to the given condition, L= 3W. Further we'll solve by putting L= 3W in the formula for rectangle.

A=LW

As given A= 19,500 sq.ft and considering L=3W,

19,500 = 3W*W

19,500 = 3W^2

∴ W^2 = 6500

∴ W = [tex]\sqrt{6500}[/tex]

∴ W = 80.6225 ft. ≈ 80.62 ft.

Now putting the value W = 80.62 in equation L =3W,

L = 3* 80.62

L = 241.86 ft.

The length of the rectangular playground is 241.86 foot.

The equation of the linear line that best fit the given points is y = (7/8)x + 7/8.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

The line passes through points (-1,0) and (7,7) will be the best fit as it is at the smallest distance between all points.

The linear function associated with the point (-1,0) and (7,7) will be as,

y - 0 = [(7 - 0)/(7 + 1)](x + 1)

y = (7/8)(x + 1)

y = (7/8)x + 7/8

Hence "y = (7/8)x + 7/8 is the equation of the linear line that best fits the provided points".

A degree 5 function can have up to five turning points. These turning points are also known as stationary points, inflection points, or extrema.

A degree 5 function is a polynomial of degree 5. This means that it is a function of the form f(x) = ax^5 + bx^4 + cx^3 + dx^2 + ex + f, where a, b, c, d, e, and f are constants. The degree of a function is determined by the highest power of the variable in the equation. In this case, the highest power of x is 5, and so the degree is 5. A degree 5 function can have up to five turning points. These turning points are also known as stationary points, inflection points, or extrema. A stationary point is a point on the graph of the function where the slope of the graph is either 0 or undefined, and an inflection point is a point on the graph of the function where the concavity of the graph changes. In order for a function to have a turning point, the derivative of the function must equal 0 at that point, and the second derivative of the function must not equal 0. If the second derivative does equal 0 at the point, then the point is a point of inflection, rather than a turning point. The number of turning points of a degree 5 function can be determined by finding the number of real roots of the equation f'(x) = 0, where f'(x) is the derivative of the function f(x). Since the degree of the derivative of a degree 5 polynomial is 4, this equation will have up to 4 real roots. This means that the degree 5 function can have up to five turning points.

The graph of a linear equation in two variables is a straight line.

The general linear equation in two variables is ax + by + c = 0, where a, b, c are constants. Also, a and b cannot both equal zero at the same time.  In order to graph of a linear equation in two variables  ax + by + c = 0, we simply assume a set of values for x and calculate the respective set of values for y.

So we have a set of coordinates (x, y). Now plot the points on graph and join them.

The graph formed will be a straight line.

The point at which the line (graph of a linear equation) crosses the y-axis is the y-intercept and the point at which the line (graph of a linear equation) crosses the x-axis is the x-intercept.

Therefore, the graphing of all ordered pairs that satisfies a linear equation in two variables gives a straight line.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the y-intercept. Using the information given we can plug in the numbers to get the correct equation. This looks like y=-3x+4.

Slope-intercept form is helpful because we can use it to find coordinate points and graphs. By graphing the y-intercept and then using the slope to count out points, you can find the function. Additionally, by plugging in values for x or y, you can find coordinate pairs.

The standard form is Ax + By = C

Where, if at all possible, A, B, and C are integers, and A is non-negative.  Our linear equation in standard form is:

x - 5y = -12  or 1x - 5y = -12

The value of x is six when f(x) = 64, and there are 64 subscribers completed on a training video service at week 6. So, correct answer is option (A).

In the exponential function, the independent variable or x-value is the exponent and the base is constant. The exponential formula is y = abˣ, where a and b are constants. For example, y = 2ˣ is exponential.

We have, the number of subscribers of a training video is double each week. The function f(x) represent the number of ubcriber in week x, f(x) = 2ˣ

we have to calculate value of x that is week when f(x) = 64 or there is 64 subscribers. So, 2ˣ = 64 --(*)

Introducing logarithms both sides of equation (*) we get,

=> log (2ˣ) = log 64

=> x log 2 = log 64 (log rule, log aˣ= x log a)

divide both sides by log 2

=> x log 2/log 2 = log 64/log 64

=> x = log 64/log 2 = log (2⁶)/ log 2

=> x = 6 log 2/log 2 = 6

The three correct answers that describe the given transformations are;

A) To create g, the graph of f is shifted 5 units up.

C) The graph of f is steeper than the graph of g.

F) The y-intercept of g is 5 units above the y-intercept of f.

We are given the equations as;

f(x) = x

g(x) = ¹/₃(f(x)) + 5

For a function f(x) we define a vertical translation (or vertical shift) of n units as:

g(x) = f(x) + n

If n is positive, the translation is upwards

If n is negative, the translation is downwards.

Thus, the graph of f was shifted 5 units upwards.

Now, the equation of a line in  slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus;

y-intercept of f(x) = 0

y-intercept of g(x) = 5

Thus;

y -intercept of g is 5 units above y-intercept of f.

Now, the steeper the line, the higher the slope. Thus, function f has a higher slope than function g and so function f is steeper than function g.

The graph of the line parallel to x-axis and passes trough the point (-2,3).

What is slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.

Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is

m = Δy/Δx  = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be shown as

tan θ = Δy/Δx.

Given that the slope of the line is 0. Thus the angle between the line with the x-axis is 0 degree as tan 0° = 0.

The line is parallels to x-axis.

The equation of the line that is parallel to x-axis is y = a.

Since the line passes through the point (-2,3), thus it will be satisfies the equation line.
