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?
What is Napier's constant? What is the expected value of a constant? What is an extraneous variable? What is an independent and dependent variable? What is an example of an independent variable? What is Euler's constant? What is the dielectric constant? What is another term for the manipul...
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...
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...
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...
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 ...
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...
Constants are useful when declaring the length of a static array, which is fixed at compile time. Listing 4.2 in Lesson 4, “Managing Arrays and Strings,” includes an example that demonstrates the use of a const int to define the length of an array. Constant Expressions Using constexpr The...
An example of a test using a dichotomous independent (input) variable is the independent 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...
What is an example of a constant in daily life? The 24-hour cycle of a day is a constant in daily life, always remaining the same. 8 What does it mean when a company achieves sustained growth? It means the company has maintained a certain level of growth over a period, indicating ste...
