Chapter 10 Review

Front

Solve for x: 2x + 4 = 20

Back

x = 8

Front

What is the equation of a circle with center (-1, -1) and radius 3?

Back

(x + 1)² + (y + 1)² = 9

Front

Convert to standard form: x² + y² + 6x - 10y - 15 = 0

Back

(x + 3)² + (y - 5)² = 49

Front

Solve for a: 3a + 2 = 20

Back

a = 6

Front

Two tangents from a point outside a circle are equal in length. If the length of one tangent is 14, what is the length of the other tangent?

Back

14

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c

Front

Define a tangent line to a circle.

Back

A tangent line is a straight line that touches the circle at exactly one point.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

d = √((x2 - x1)² + (y2 - y1)²)

Front

What is the formula for the area of a circle?

Back

A = πr²

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.
