What is an example of a constant monomial? Prove that if y = y_0e^{kt} , where y_0 and k are constants, then \frac{dy}{dt} = ky . Find the constant term in the expansion of (x + {2}/{x^2})^{15}. What is constant of proportionality?
Let us take an example of the algebraic expression 2x + 6. Here, x is a variable and can take any value. If x = 1, the value of this algebraic expression will be 2(1) + 6 i.e. 8 and if x = 2, the value of the algebraic expression changes to 10. Hence, we can say that...
What is a constant variable? What is an example of a dependent variable in science? What is an example of an independent variable? What are confounding variables? What is another term for the manipulated variable? What is the relationship between a constant and a variable?
Below is an example of a variable in the Perl programming language.my $fullname = "Computer Hope";print "There is hope, $fullname";In the example above, the variable, named fullname, is declared using the Perl keyword my. In Perl, the dollar sign $ indicates that fullname is the ...
Another example of a variable expense is a retailer’s cost of goods sold. For instance, if a company purchases a product for $30 and is able to sell it for $50, the company’s cost of goods sold will be a constant rate of 60% ($30 / $50). Therefore, when the company has sal...
An example of a test using a dichotomous independent (input) variable is theindependent samples t-test, illustrated below. In this test, the dichotomous variable defines groups of cases and hence is used as a categorical variable. Strictly, the independent-samples t-test is redundant because it...
The below code is an example of an asynchronous test method using Swift’s new async/await syntax. The testWebLinkAsync method uses the URLSession API to download the webpage at the specified URL, and asserts that the response is an HTTP 200 OK status code. func testWebLinkAsync() async...
As you can see from the figure above, the general shape or graph of an exponential function can either show a growth or a decay. If there is exponential growth, as shown in the figure on the left, the graph will curve upward. A real life example of exponential growth is population ...
In here, “Hello World” is a string literal constant. You literally have been using literal constants all the while! When you declare an integer someNumber, like this: int someNumber = 10; The integer variable someNumber is assigned an initial value of ten. Here decimal ten is a part ...
Find the variable cost per unit: $10 ÷ 1,000 = $0.01 per unit Therefore, the variable cost per unit is $0.01. What is an example of a variable cost? An example of a variable cost is the cost of raw materials used to produce a product. The cost of raw materials will vary depen...
