Answer: (B) 130 cm

Proof: If a chord and a line from the centre meet, they must be perpendicular. The line from the centre to the chord also bisects the chord. If the distance from the centre of the circle to the chord is 52 cm and the distance of half of the chord is 39 cm, then you can work out using Pythagoras' Theorem the distance of the radius.

r² = 52² + 39²
r² = 4225
r = 65

Thus, the diameter is 2r = 130 cm

kifflom [539]

Answer:

A) 12y^{3}

Step-by-step explanation:

A) \frac{12y^{3} }{6y^{2} }

=\frac{2y(6y^{2} )}{6y^{2}}

= 2y

B) \frac{24y}{6y^{2} }

Solve for x and y.<br> y = 2/3x - 2<br> y = -x + 3
sesenic [268]

Answer:

1. x= 3y+6/2

y=2/3x-2

2.x=−y+3

y=−x+3

Step-by-step explanation:

1. Let's solve for x.

y=2/3x-2

Step 1: Flip the equation.

2/3x-2=y

Step 2: Add 2 to both sides.

2/3x-2+2=y+2

2/3x=y+2

Step 3: Divide both sides by 2/3.

2/3x/2/3=y+2/2/3

x= 3y+6/2

Let's solve for y.

y=2/3x-2

2. Let's solve for x.

y=−x+3

Step 1: Flip the equation.

−x+3=y

Step 2: Add -3 to both sides.

−x+3+−3=y+−3

−x=y−3

Step 3: Divide both sides by -1.

-x/-1=y-3/-1

x=−y+3

Let's solve for y.

y=−x+3

42500-25500= 17000

i multiplied 10% by 6 because 2027 is 6 years away and i subtracted 42500 by 25500 because it says it "decreased"
