Step 4: Translate into an equation by writing the appropriate formula. Substitute in the given information. Step 5: Solve the equation. Step 6: Check the answer in the problem and make sure it makes sense. Does \(5\) seconds seem like a reasonable length of time? Yes. Step 7: Answer the equation.
A radical equation is any equation that contains one or more radicals with a variable in the radicand. Following are some examples of radical equations, all of which will be solved in this section: √x − 1 = 5 √2x − 5 + 4 = x 3√x2 + 4 − 2 = 0.
31 paź 2021 · Radical Equations. A radical equation is any equation that contains one or more radicals with a variable in the radicand. Following are some examples of radical equations, all of which will be solved in this section: √2x − 1 = 3. 3√4x2 + 7 − 2 = 0. √x + 2 − √x = 1.
General Solution Steps: Step 1. Isolate the Radical(s) and identify the index (n). Step 2. Raise both sides of the equation to the “nth” power. Step 3. Use algebraic techniques (i.e. factoring, combining like terms,...) to isolate the variable. Repeat Steps 1 and 2 if necessary. Step 4. Check answers.
1 Radical Equations. An equation that has the variable to be solved for inside a radical is called a radical equation. The algebraic manipulations (described below) needed to solve the equation for the variable can be involved, and may result in extraneous solutions.
The T shoulder height h (in centimeters) of a male Asian elephant can be modeled by the t function h 62.5 75.8, where t is the age (in years) of the elephant. Use 3 √— t = +. a a graphing calculator to graph the function. Estimate the age of an elephant whose shoulder s height is 200 centimeters.
