What is a zero of a function?

Back

A zero of a function is a value of x for which the function evaluates to zero, meaning the graph of the function intersects the x-axis.

How do you find the zeros of a polynomial function?

Back

To find the zeros of a polynomial function, set the function equal to zero and solve for x, either by factoring, using the quadratic formula, or other methods.

What is the formula for the length of an arc in a circle?

Back

The length of an arc (L) is given by the formula L = rθ, where r is the radius and θ is the central angle in radians.

Front

How do you convert the length of an arc to a central angle?

Back

To find the central angle θ in radians, use the formula θ = L/r, where L is the length of the arc and r is the radius.

Front

What is the process of factoring a polynomial?

Back

Factoring a polynomial involves expressing it as a product of its factors, which can be found by identifying common factors or using methods like synthetic division.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a quadrilateral with one pair of parallel sides (bases) and the non-parallel sides (legs) being equal in length.

Front

How do you calculate the area of an isosceles trapezoid?

Back

The area (A) of an isosceles trapezoid can be calculated using the formula A = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the bases and h is the height.

Front

What is the significance of the central angle in a circle?

Back

The central angle is the angle whose vertex is at the center of the circle and whose sides intersect the circle, determining the arc length and sector area.

Front

What is the relationship between the roots of a polynomial and its factors?

Back

The roots (or zeros) of a polynomial correspond to the values of x that make each factor equal to zero, thus providing solutions to the polynomial equation.

Front

How do you determine the number of pieces needed to cover an area?

Back

To determine the number of pieces needed, divide the total area to be covered by the area of one piece.
