Answer:
Step-by-step explanation:
<u>Quadratic Equation</u>
A quadratic equation also called a second-degree equation is a special polynomial whose highest degree is two.
The general form of the quadratic equation is
Where a is known as the leading coefficient. Another form to write the quadratic equation is
Where x1 and x2 are the roots or zeroes of the equation.
We have the roots of the given equation are -2 and 2, and the leading coefficient is 3.
Plugging in the given values we have
Operating
1) add, equal
2) multiply, equal
3) subtract, equal
<span>Grounding on boats is something like a mystery to most of the people. They think that the factory hooked it up like that and therefore the installation must be correct. But that's something which will not work every time.</span>
Thus if you are grounded aboard a small powerboat then place everybody aboard in the center of the boat and<span> t</span>ry to kedge your boat off the obstruction.
Arc length from A to C (red line) is the given inside angle times 2, so AC = 50*2 = 100 degrees.
A full circle is 360 degrees, so arc ABC (blue line) would be 360 - 100 = 260 degrees.
The answer is D.
It would equal 84 over 3, or 28.
