Answer:

Hi there!

The correct answer to this question is: 56.55

Step-by-step explanation:

A semicircle is another way of saying half a circle, if we know the area of a circle is A= π * r^2   then all we have to do is take this equation and divide it by  two to get the area of a semicircle. Additionally since we are given the diameter we need to divide that by 2 to get the radius which is six.

Now we can plug all the components into the equation: A= (1/2)(π)(6^2)

you get 56.55

Use the quadratic formula to find the solutions to the quadratic equation below x^2-6x-5=0
Sonja [21]

Answer:

\large\boxed{x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}}

Step-by-step explanation:

x^2-6x-5=0\qquad\text{add 5 to both sides}\\\\x^2-6x=5\\\\x^2-2(x)(3)=5\qquad\text{add}\ 3^2\ \text{to both sides}\\\\x^2-2(x)(3)+3^2=5+3^2\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\(x-3)^2=5+9\\\\(x-3)^2=14\to x-3=\pm\sqrt{14}\qquad\text{add 3 to both sides}\\\\x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}
