Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.

Alla [95]

Considering the given equation of the circle, the true statements are given as follows:

The radius of the circle is of 3 units.

The center of the circle lies on the x-axis.

The circle has the same radius as the circle with equation x² + y² = 9.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

The equation given is:

x2 + y² - 2x - 8 = 0.

Completing the squares, the equation is given as follows:

(x - 1)² + y² = 8 + 1

(x - 1)² + y² = 9.

Researching the problem on the internet, the true statements are:

The radius of the circle is of 3 units.

The center of the circle lies on the x-axis( $y_0 = 0$ ).

The circle has the same radius as the circle with equation x² + y² = 9.

A piece of string is 112 inches long. Isabel wants to cut it into 2 pieces so that one piece is three times as long as the other

lukranit [14]

Answer:28inches & 84inches

First, lets write an equation that fits the data given. The string is 112 inches long. When the two pieces are cut, the first piece will be three times as long as the second piece. If we use the variable, x, to represent the second piece, we can create the following equation...

112=3x+x

Now lets solve for x.

112=4x
divide both sides by 4
28 inches=x

Now we know that the second piece is 28inches long. Since the first piece is three times as long, simply multiply 28*3 and we'll know the length of the first piece.

28*3=84 inches
28+84=112
