Answer: a. 55
Step-by-step explanation:
The formula to find the geometeric mean between two numbers a and b is given by :-

The given numbers are : 275 and 11
The geometric mean of 275 and 11 is given by :-

Hence, the geometric mean of 275 and 11 is 55.
So , the correct option is a. 55 .
Answer
The answer is 567
Step-by-step explanation:
189*3=567
The exponential form of this equation is "0.8⁴ = 0.4096 ".
Now, in this logarithm equation the base of the log is 0.8.
when we convert this equation to exponential form 0.8 will go to left side, 4 moved up and became the exponent of 0.8 and thus it makes the exponential equation;
4=log₀.₈ 0.4096 <span>logarithmic equation
0.8</span>⁴ = 0.4096 exponential form
A circle is 360° , if youdivide<span> an arc's </span>degree measure<span> by 360°, you find the fraction of the circle's </span>circumference<span> that the arc</span>makes<span> up. Then, if you multiply the length all the way around the circle </span>by that fraction, you get the length along the arc.
D. Only 1 and 4
2, 3 aren't quadrilateral
