Use the quadratic formula to solve the equation -3x2-x-3=0
Novosadov [1.4K]

Answer:

x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\

Step-by-step explanation:

the quadratic formula is:

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

a= -2, b = -1 and c =-3

Putting values in the formula

x=\frac{-(-1)\pm\sqrt{(-1)^2-4(-3)(-3)}}{2(-3)}\\x=\frac{1\pm\sqrt{-35}}{-6}\\x=\frac{1+\sqrt{-35}}{-6}\,\, and\,\, x=\frac{1-\sqrt{-35}}{-6}\\We\,\, know \,\,that \,\,\sqrt{-1} = i  \\x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\

So, x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\

Find the area of a circle circumscribed about an equilateral triangle whose side is 18 inches long. 81 108 243
jekas [21]

Answer:

Area=339.2920in^2 \ or \ 108\pi \ in^2

Step-by-step explanation:

Area of circle is given as:

A=\pi\ r^2

Where r=radius

To find radius of a circle circumscribing an equilateral triangle, we use the expression

r=\frac{a\sqrt3}{3}

Where, a is the length of sides of the equilateral triangle. Therefore:-r=\frac{18\sqrt3}{3}\\r=6\sqrt3 \ or \ 10.3923in

We can then proceed and calculate the area of the circle as follows:-

A=\pi\ r^2\\A=\pi(10.3923)^{2}\\A=339.29\ or \ 108\pi

*The attached picture illustrates what the circumscribed equilateral triangle looks like
