Answer:

true

Step-by-step explanation:

The diameter of a circle is a single line segment that stretches the entire width of the circle, intersecting with the center point and two points around the circumference. The diameter measures how wide the circle is, and is always equal to twice the radius (2r).

Answer:

Step-by-step explanation:

12−5+6=0

using the Quadratic Formula where

a = 1, b = -5, and c = 6

=−±2−4‾‾‾‾‾‾‾‾√2

=−(−5)±(−5)2−4(1)(6)‾‾‾‾‾‾‾‾‾‾‾‾‾‾√2(1)

=5±25−24‾‾‾‾‾‾‾√2

=5±1‾√2

The discriminant 2−4>0

so, there are two real roots.

Simplify the Radical:

=5±12

=62=42

which becomes

hope this helps :)

Nishi invests £2200 at 5% interest per year.

lord [1]

I =(2200×5%×3)/100
=3.3
3 years = 3.3 +2200
= 2203.30
I =(2200×5%×5)/100
=5.50
5 years =5.50 +2200
= 2205.50

The solution set for the equation x - 6x + 10 = 0 is

Oxana [17]

Answer:

{3-i, 3+ i}

Step-by-step explanation:

hello : the equation is : x²-6x+10 =0

because : (3+i)²-6(3+i)+10 = 9+6i+i²-18-6i+10 =9+6i-1-18-6i+10 =0...right

same method for 3-i... (all quadratic equation have two conjugate solution)
