What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Angle c is inscribed in circle O. AB is a diameter of circle O. what is the radius of circle.

Llana [10]

Answer:

The value of radius is 7.5 units

Step-by-step explanation:

Given that a line that pass through the origin and form a triangle is a right-angle triangle. So in order to find the diameter/hypotenuse, you have to use Pythogaras Theorem :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 12 units,

Let b = 9 units,

Let c = hypo.,

${hypo.}^{2} = {12}^{2} + {9}^{2}$

${hypo.}^{2} = 225$

$hypo. = \sqrt{225}$

$hypo. = 15 \: \: units$

We have found out that the hypotenuse of the triangle is the diameter of circle. So in order to find radius, you have to divide it by 2 :

$radius = diameter \div 2$

$radius = 15 \div 2$

$radius = 7.5 \: \: units$
