The sum or product of a non-zero rational number and an irrational number is always

Mathematics

6 0

Answer:

Irrational

Step-by-step explanation:

A rational number and an irrational number when added will given another irrational number only.

Example consider a rational number 2 and an irrational number √3.

When we add these two we get

2+√3. an irrational number only

There is no chance of getting a rational number when a non zero rational and irrational is added.  In other words, there is nothing to cancel the irrational part when another rational number is added.

Hence the result would be irrational

Thus answer is irrational.

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
