Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header files
#include<math.h>
int main() //main method
{
double treeHeight = 0.0; //declare variables
and assign value
double shadowLength = 0.0;
double angleElevation = 0.11693706;
// (0.11693706 radians = 6.7 degrees) convert number into angle.
shadowLength = 17.5;
treeHeight = shadowLength * tan(angleElevation); //convert number into angle
printf("Tree height: %lf\n", treeHeight); //print value.
return 0;
}
Output:
Tree height: 2.055778
Explanation:
In the above C language program firstly we include the headers. In this header file, we include a (math.h) header file this file helps to use the math function. Then we declare the main method in the main method we declare the variable that is given in the question that are treeHeight, shadowLength , angleElevation. All the variable datatype is double because it stores the floating-point value. Then we apply the formula that is treeHeight = shadowLength * tan(angleElevation). In this formula, the treeHeight variable holds the value. Then we print the variable value for print the double value we use the lf(that is long float).
Answer: None of the given option is correct
Explanation:
A serializable class is implemented, when an object is serializable interface. If you want to serialize one of your classes, then the class must implemented in the Serializable interface. To implement the serializable interface, convert a class into the series of bytes and when serializable object might reference your class. Serializable classes are useful when you wanted to persist cases of the class or send them over wire.
Answer:
I'd choose A, all of the above.
Reasoning Why:
I'll be taking you on a step to step process on why I inputted the answer.
The <div>, is basically like a container that you can group tougher, why this is great is because you can edit the div using a background-color effecting that group such as the following..
EXAMPLE OF BACKGROUND-COLOR DIV (background-color)
<!DOCTYPE html>
<html>
<head>
<title>Brainly Example | HTML Div</title>
<style>
#byexample{
background-color:red;
/*Example of the Background-color attrib*/
/*You can also use the background-image attrib, however I recommend you checkout W3Schools, on that topic.*/
}
</style>
</head>
<body>
<div id="byexample">
<p>Just some random text to demonstrate.</p>
</div>
</body>
</html>
END OF EXAMPLE
You can also, in the <div> change multiple styles of an element in the div. However, if do want to change the styles of a single element you would need to nest it.
<!DOCTYPE html>
<html>
<head>
<title>Brainly Example | HTML Div</title>
<style>
#byexample #text{
background-color:red;
color:yellow;
}
</style>
</head>
<body>
<div id="byexample">
<p id="text">Just some random text to demonstrate.</p>
</div>
</body>
END OF EXAMPLE
Lastly, you can group elements using divs, as stated in openclassroom (website).
Anyways, I hope this helped!
Happy coding!
