The number of ubcriber to a treaming video ervice double each week. The function f(x)=2x repreent the number of ubcriber in week x. When are there 64 ubcriber?
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).
What is exponential function?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
so, x = 6 , Hence, the required week i.e x is 6.

How do you find the missing number in a given integer array of 1 to 100 in PHP?
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
$diff = array_diff($array1, $array2);The result of this will be an array containing the missing integer.

What theorem is being applied if two triangles of one triangle are congruent to two angles of another triangle and the triangles are similar?
Triangle congurent theorem is being applied if two triangles of one triangle are congruent to two angles of another triangle and the triangles are similar.
Angle-Side-Angle (ASA) theorem states that if two triangles are considered congruent, then the two corresponding angles equal to each other will include a corresponding side that is equal to each other.
By applying the Side Angle Side Postulate (SAS), you can also be sure your two triangles are congruent. Here, instead of picking two angles, we pick a side and its corresponding side on two triangles.
The SAS Postulate says that triangles are congruent if any pair of corresponding sides and their included angle are congruent.
Perhaps the easiest of the three postulates, Side Side Side Postulate (SSS) says triangles are congruent if three sides of one triangle are congruent to the corresponding sides of the other triangle.

What are the 3 forms of linear equations?
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
where A = 1, B = -5, and C = -12

5. A student graphed f of x. equals. x. and g of x. equals. 1 over 3. f of x. plus 5 on the same coordinate grid. Which statements are true?
Select THREE correct answers.
To create g, the graph of f is shifted 5 units up.
To create g, the graph of f is shifted 5 units down.
The graph of f is steeper than the graph of g.
The graph of g is steeper than the graph of f.
The y-intercept of g is 5 units below the y-intercept of f.
The y-intercept of g is 5 units above the y-intercept of f.
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.
How to find the sequence of transformation?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.

A playground is in the shape of a rectangle. The length of the rectangle is three times its width. The area of the playground is 19,500 square feet. What is the length of the playground? Round to the nearest foot. Hint: use A=LW
The length of the rectangular playground is 241.86 foot.
How to calculate length of the rectangle?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.
Calculation: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.

How do you translate an entire triangle?
To translate an entire triangle, find the coordinates of each of the triangle's vertices, add the horizontal translation then plot the three translated points
Whenever an object is moved from one location to the next without changing its size, shape, or orientation, a translation takes place. If we know which way and how far the figure to be moved, we can draw the translation in the coordinate plane.
There are some steps of translating the triangle:
Step 1: Find the coordinates of each of the triangle's vertices in step one.
Step 2: Add the horizontal translation value to each vertex's x-coordinate and the vertical translation value to each point's y-coordinate to translate each point. If the horizontal translation is to the left or the vertical translation is downward for these translations, add a negative number.
Step 3: Plot the three translated points and draw the triangle by drawing a straight line between each pair of points.

What line is perpendicular to line that has a slope of 1 3?
The level of a line's slope indicates its steepness.
A line with a slope of 1/3 has a perpendicular line with a slope of -3. The product of the slope is equal to -1 when two lines are perpendicular.
How do one find the slope of a graph?The slope is computed mathematically as "rise over run" (change in y divided by change in x).
In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.
That is to say,
Determine the coordinates of two locations along the line that one choose.Evaluate the differences in these two positions' y-coordinates (rise).Evaluate the differences in these two locations' x-coordinates (run).In order to calculate the difference in y-coordinates (rise/run or slope), divide it by the difference in x-coordinates.To know more about slope refer to:
