Bankers and people interested in rates of growth prefer this form. Assume that t is measured in years.
A variable is a letter that represents a number. Don't let the fact that it is a letter throw you.
Since it represents a number, you treat it just like you do a number when you do various mathematical operations involving variables. Evaluating an Expression You evaluate an expression by replacing the variable with the given number and performing the indicated operation.
Value of an Expression When you are asked to find the value of an expression, that means you are looking for the result that you get when you evaluate the expression. So keep in mind that vary means to change - a variable allows an expression to take on different values, depending on the situation.
For example, the area of a rectangle is length times width. Well, not every rectangle is going to have the same length and width, so we can use an algebraic expression with variables to represent the area and then plug in the appropriate numbers to evaluate it.
So if we let the length be the variable l and width be w, we can use the expression lw. If a given rectangle has a length of 4 and width of 3, we would evaluate the expression by replacing l with 4 and w with 3 and multiplying to get a value of 4 times 3 or Plugging in the corresponding value for each variable and then evaluating the expression we get:The problems in this lesson involve writing radicals in exponential form.
To write radicals as exponents, the root of the radical becomes the denominator of the fraction in the exponent, and the power on the radical becomes the numberator of the fraction on the r-bridal.com://r-bridal.com /writing_radicals_in_exponential_form.
Answer: Explanation: Recall what the relationship between logarithmic functions and exponential functions are; they are inverses. In order to convert a log function into an exponent, we need three things: the base, the power, and the r-bridal.com://r-bridal.com 37 quotes on work as self-expression.
As one of my most profound mentors put it, “work is the ultimate form of self-expression.” We need to do the work that makes us come alive, that helps us operate at a higher level, and that makes our soul sing.
