We use a conjecture that says that the perpendicular bisector of a chord in a circle passes through the center of the circle.

The distances of the two bisectors are the same so the chord lengths are the same.

b = half of 22.5 = 11.25

The answer to your question is 11.25.

Help please!!! I don't understand

zaharov [31]

$\left|x-\dfrac 12\right| = 3\dfrac 23\\\\\\\implies \left|x- \dfrac 12 \right| = \dfrac{11}3\\\\\\\implies x-\dfrac 12 = \dfrac{11}3 ~~~~~~~~~ \text{or}~~~~~~~ x - \dfrac 12 = - \dfrac {11}3\\\\\\\implies 2x -1 = \dfrac{22}3 ~~~~~~~~ \text{or}~~~~~~~~2x-1 =-\dfrac{22}3\\$

$\implies x =\dfrac 12\left(\dfrac{22}3 +1 \right) ~~ \text{or}~~~~~~~~ x = \dfrac 12 \left(1-\dfrac{22}3\right)}\\\\\\\implies x = \dfrac{25}6~~~~~~~~~~~~~~~ \text{or}~~~~~~~~ x=-\dfrac{19}6\\\\\\\implies x = 4\dfrac 16 ~~~~~~~~~~~~~~~ \text{or}~~~~~~~~x = -3\dfrac16$

What equation has slope of 3 and passes through 0,-2

suter [353]

Answer:

y = 3x - 2

Step-by-step explanation:

use y = mx + b

y = -2

x = 0

m (slope) = 3

b (y-intercept) = -2, since the point (0,-2) passes through the y axis.

put is as slope-intercept form:

y = 3x - 2
