Question

the following pair of equations indicate a variation on the impedance of a circuit formula introduced prior. indicate the relationship between the resulting values for each equation when solved given the following parameters:
$r = 9$
$y_t = 9$
$sqrt{y_t^2 + r^2 - y_t^2}$

Explanation:

Step1: Substitute values

Substitute \(R = 9\) and \(Y_T=9\) into \(\sqrt{Y_T^{2}+R^{2}-Y_T^{2}}\).
$$\sqrt{9^{2}+9^{2}-9^{2}}$$

Step2: Simplify the expression

Simplify \(9^{2}+9^{2}-9^{2}\).
$$\sqrt{9^{2}}$$

Step3: Calculate the square - root

Calculate \(\sqrt{9^{2}}\).
$$9$$

Answer:

\(9\)
