How do you reverse a string in PHP without using a function?
Without any function is impossible. So I'll assume you mean any coded function, in which case the predefined function below is your answer.$string = strrev($string);
How do you return a value in a PHP function?
Below is a simple example of how you could return a value in a PHP function. <?php function returnme($value) { return $value; } echo returnme('hello'); // outputs: hello ?>
How do you create static variables in PHP?
Use the "static" keyword to declare a static variable within a function like shown below. <?php function fun() { static $variable; static $another_variable = ''; } ?>
Which equation below represents the inverse function M which takes the number of problems completed as input and returns the numbers of minutes worked?
p(m)=m/4+7
Type the capital letter that represents this equation after it has been correctly balanced Press Enter?
The capital letter that represents a balanced chemical equation is "E".
Which answer represents the domain of the logarithmic function given below F(x) log7 x?
X>0
Solve the equation for x and enter your answer in the box below?
To solve an equation for x, you need to isolate the variable on one side of the equation. Start by performing the inverse operation to undo any addition, subtraction, multiplication, or division. Once you have x by itself, the solution will be the value of x that satisfies the equation. Remember to follow the order of operations and be careful with signs to ensure accuracy in your answer.
Which equation below represents the expression, “the difference of five times a number and 8 is sixteen”?
I would say the anwser would be 11
Which answer represents the range of the logarithmic function given below F(x) = log0.6^x?
All real numbers
What is the effect inversion?
The inverse texture effect suggests that the preferential soil texture for a given vegetation type will vary as a function of climate. Sources: See the links below.
What is an inverse Relation?
DefinitionA relationship between two numbers in which an increase in the value of one number results in a decrease in the value of the other number.The inverse of the relation(2,3), (4,5), (2,6), (4,6)is(3,2), (5,4), (6,2), (6,4)Generally we switch the roles of x and y to find the inverse.For functions, we follow the steps below to find the inverse:Step 1: Switch the x and y.Step 2: Solve for y.Step 3: Write in inverse notation.ExampleFind the inverse ofy = 2x + 1SolutionWe writex = 2y + 1We solve:x - 1 = 2yx - 1y =2We writex - 1f -1(x) =2Notice that the original function took x, multiplied by 2 and added 1, while the inverse function took x, subtracted 1 and divided by2. The inverse function does the reverse of the original function in reverse order.
What are the roots of the quadratic equation below?
That depends on the equation.
What type of chemical reaction does the balanced equation below represent?
This balanced equation represents a combustion reaction, where a fuel (C4H10) reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
Which equation below represents a generic equation suggested by a graph showing a hyperbola?
A hyperbola is another form of a conical section graph like a parabola or ellipse. Its general form is x^2/a - y^2/b = 1.
How do you calculate arc sine?
arc sine is the inverse function of the sine function so if y = sin(x) then x = arcsin(y) where y belongs to [-pi/2, pi/2]. It can be calculated using the Taylor series given in the link below.
