Given:
The point (7, 4) lies on a circle centered at the origin.
To find:
The equation of the circle and the radius of the circle.
Solution:
Distance formula:

The point (7, 4) lies on a circle centered at the origin. So, the distance between the points (7,4) and (0,0) is equal to the radius of the circle.




The standard form of the circle is
...(i)
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=0, k=0 and
in (ii), we get


Therefore, the equation of the circle is
and its radius is
.
The 5 in 34,562 stands for 500. The other 5 in 125,348 stands for 5,000. :)
Answer:
C is correct
Step-by-step explanation:
a is wrong because: 1*-1*-1*-1 =1
b) 1*1*1*1 =1
d) 1*-1*1*1 =1
only c 1*-1*-1*1 =-1 at the end of polynomial
Multiply 30 by 30%.
=30 * 30%
convert % to decimal (30% ÷ 100)
=30 * 0.30
=9
ANSWER: 9 is 30% of 30.
Hope this helps! :)
