The circle below is centered at the origin and has a radius of 10. What is its<br> equation?

xz_007 [3.2K]

Answer:

x^2 + y^2 = 100

Step-by-step explanation:

The general form of the equation of a circle is

(x-h)^2+(y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x-0)^2+ (y-0)^2 = 10^2

x^2 + y^2 = 100

Find the value of this fraction 6 x 1/2 + 2/3 + 3/4

kodGreya [7K]

Answer:

$\frac{53}{12} or 4 \frac{5}{12}$

Step-by-step explanation:

$\frac{6}{1} \times \frac{1}{2} = 3$

$\frac{3}{1} + \frac{2}{3} + \frac{3}{4} = ...$

Find the common denominator, which is 12

$\frac{36}{12} + \frac{8}{12} + \frac{9}{12} =$

Now add them

$\frac{36}{12} + \frac{8}{12} = \frac{44}{12} + \frac{9}{12} = \frac{53}{12}$

Simplified version is

$4 \frac{5}{12}$
