Find the length of the radius of a circle whose center is at the origin and passes through (3,4)

Harman [31]

well, by definition the distance from the center to a point on the circle is the radius. Well, we know the center is at 0,0 and a point is at 3,4, so

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(3-0)^2+(4-0)^2}\implies r=\sqrt{3^2+4^2} \\\\\\ r=\sqrt{9+16}\implies r=\sqrt{25}\implies r=5$

1/3(x+6)=1/2(x-3) I need answer and explanation thanks

____ [38]

Answer:

x = 21

Step-by-step explanation:

1/3(x + 6) = 1/2(x - 3)

(3)1/3(x + 6) = (3) 1/2(x - 3) - multiply both sides by 3 to get rid of the 1/3

x + 6 = 3/2(x - 3)

x + 6 = 3/2 (-9/2) - i distributed the 3/2 into the parenthesis

x + 6 (2) = 3/2 (-9/2) (2) - multiply each side by 2 to get rid of the fractions

2x + 12 = 3x - 9

2x - 3x = -12 -9 - bring the x to one side

-x = -21

-x/-1 = -21/-x

x = 21
