ABC is a right angled triangle right angled at B . A circle with centre O inscribed in the triangle . AB=6CM BC=8CM . Find the r
Vikki [24]

Answer:

Radius = 2 cm.

Step by step explanation:

By the Pythagoras theorem  the third side of the triangle

= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.

The formula for the radius of the circle is

r = sqrt [ (s - a)(s-b)(s-c)/ s ]  where a,b,c are side lengths and s = the semi perimeter.

Here s = ( 6+8+10) / 2 = 12

So the radius r  

= sqrt [ (12-6)(12-8)(12-10)/ 12 ]

= sqrt 4

= 2 (answer).

Solve 3x^2 + x + 10 = 0 round solutions to the nearest hundredth
lara31 [8.8K]

Answer:

C. X= -2.01 and x= 1.67

Step-by-step explanation:

3x {}^{2}  + x + 10 = 0 \\ 3x {}^{2}  + 6x - 5x + 10 = 0 \\ 3x(x + 2) - 5(x + 2) \\ (x + 2)(3x - 5 )\\  x  + 2 = 0 \:  \: or \:  \: 3x - 5 = 0 \\ x =  - 2 \:  \: or \:  \: x =  \frac{5}{3}
