What are the roots of the quadratic equation x2+2x=-5
stiks02 [169]

Answer:

x = -1 +/-2i

Step-by-step explanation:

Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.

x² + 2x + 5 = 0

Use the quadratic formula by substituting a= 1, b = 2 and c = 5.

x = \frac{-2 +/- \sqrt{(-2)^2 - 4(1)(5)} }{2(1)} = \frac{-2 +/-\sqrt{4 -20 } }{2} = \frac{-2 +/-\sqrt{-16 } }{2} = \frac{-2 +/-4i }{2} = -1 +/-2i

Find the length of each arc<br> r=13 ft x=90 degrees
VladimirAG [237]

Answer:

13\pi/2

Step-by-step explanation:

The formula of the circumference of a circle is 2\pi r.

The length of an arch can be found by using the ratio of circumference to the arc.

First, find the circumference of the circle:

2\pi *13=26\pi

Then you find the ratio:

The length of the arc is 90/360, which is 1/4, of the circumference.

Finally, find the length of the arc:

26\pi*1/4=(13/2)\pi or 13\pi/2

I hope this helps :)
