Answer:
length of chord is 6cm
Step-by-step explanation:
Here, we are to calculate the length of the chord.
It should be understood that the chord has a length of 0.8cm from the center of the circle of radius 3cm, thereby forming two right-angled triangles with the radius 3cm being the hypotenuse of each and 0.8cm being the height of each.
Now, the chord is divided into 2 by this height dropping from the center of the circle. To calculate the first half, we use Pythagoras’ theorem with 3cm being hypotenuse and 0.8cm being the other side.
mathematically;
3^2 = 0.8^2 + l^2
9 = 0.64 + l^2
l^2 = 9-0.64
l^2 = 8.36
l = √(8.36)
l = 2.89 approximately
The length of the chord would be 2l = 2 * 2.89 = 5.78 cm which is 6cm to the nearest length
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(3, 0)
Equation Form:
x = 3, y = 0
The factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).
<h3>What is the factored form of the given expression?</h3>
Given the expression;
x² + x - 2
Consider the standard form ax² + bx + c compared to the given expression;
Now, we find a pair of integers whose product gives the value of c which is -2 and whose sum gives the value of b which is 1.
The integers are -1 and +2.
Check
-1 × 2 = -2
-1 + 2 = 1
Now, we write the factored form using these integers.
( x - 1 )( x + 2 )
Therefore, the factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).

13+2x+12=x+32
25+2x=x+32
X=7
So AB would be 27
the answer is no solution
