Answer:
-12f
Step-by-step explanation:
I found the image that should have accompanied this problem.
The triangle inside the circle is an isosceles triangle. It has 2 equal sides and 2 equal angles.
Angle A = 70° , Angle C is also 70°. This leaves angle R having 40°.
The arc opposite angle R is twice the measure of its angle.
Angle R = 40°
Arc AC = 40° x 2 = 80°
The measure of arc AC is 80°.
Standard form;
(x - 2)² + (y - 6)² = 49
the center-radius form of the circle equation is in this format;
(x - h)² + (x - k)² = r²
so the center of the circle is; (2, 6)
so the radius of the circle is; 7
hope that helps, God bless!
Answer:
OPTION C
Step-by-step explanation:
We have the following rules:
![$ \sqrt[a]{x} = x^{\frac{1}{a} $](https://tex.z-dn.net/?f=%24%20%5Csqrt%5Ba%5D%7Bx%7D%20%3D%20x%5E%7B%5Cfrac%7B1%7D%7Ba%7D%20%24)
and
OPTION A: ![$ x \sqrt[7]{x} $](https://tex.z-dn.net/?f=%24%20x%20%5Csqrt%5B7%5D%7Bx%7D%20%24)
= 
= 
So, it can be eliminated.
OPTION B: ![$ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $](https://tex.z-dn.net/?f=%24%20%5Cbigg%20%28%20%5Cfrac%7B1%7D%7B%5Csqrt%5B7%5D%7Bx%7D%7D%20%5Cbigg%20%29%5E9%20%24)
= 
= 
= 
So, this option is also eliminated.
OPTION C: ![$ x . \sqrt[7]{x} $](https://tex.z-dn.net/?f=%24%20x%20.%20%5Csqrt%5B7%5D%7Bx%7D%20%24)
= 
= 
= 
So, OPTION C is the answer.
