What is the solution of the equation when solved over the complex numbers?

kumpel [21]

Answer:

$x=+i\sqrt{20}\approx+4.472i$

$x=-i\sqrt{20}\approx-4.472i$

Step-by-step explanation:

Starting from $x^2+20=0$ , we do $x^2=-20$ , which means $x=\pm\sqrt{-20}$ , which can be written as $x=\pm\sqrt{(-1)(20)}$ , which gives us $x=\pm\sqrt{(-1)}\sqrt{(20)}$ , which we know is $x=\pm i \sqrt{(20)}$ , so our solutions are:

$x=+i\sqrt{(20)}$

$x=-i\sqrt{(20)}$

Which can be approximated to:

$x\approx+4.472i$

$x\approx-4.472i$

Pat walked around a circular track she knew that the distance across The center was 100 meters if she walked around the entire t

Thepotemich [5.8K]

Answer:

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m
