To solve for Z simply add 8.2 to both sides of the equation and then divide by -1.2. After doing this, remember that since you are dividing by a negative number or multiplying by a negative fraction, you must change the inequality sign.

Use the quadratic formula to find both solutions to the quadratic equation<br> given below.

Tpy6a [65]

The solution of the equation are $x = \frac{7 + \sqrt{61}}{6}$ and $x = \frac{7 - \sqrt{61}}{6}$

<h3>How to determine the solution?</h3>

The equation is given as:

3x^2 - 7x- 1 = 0

The quadratic equation is represented as:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

So, we have:

$x = \frac{7 \pm \sqrt{(-7)^2 - 4 *3 *-1}}{2*3}$

Evaluate the expression

$x = \frac{7 \pm \sqrt{61}}{6}$

Expand

$x = \frac{7 + \sqrt{61}}{6}$ and $x = \frac{7 - \sqrt{61}}{6}$

Hence, the solution of the equation are $x = \frac{7 + \sqrt{61}}{6}$ and $x = \frac{7 - \sqrt{61}}{6}$

Let's choose 43° to be our angle. We know the opposite, and want to know the hypotenuse. Sine is the trig. we use for opposite over hypotenuse.
sinθ = opposite/hypotenuse
sin(43)=27/x
We want to isolate <em>x</em>, so that looks like:
x = 27/sin(43)
Therefore, the value of x is 27/0.682 or ≈39.589 or F
