Intro to Quadratic Word Problems Day 1 Practice

Front

What is a total solar eclipse?

Back

A total solar eclipse occurs when the moon completely covers the sun, as viewed from Earth, blocking all direct sunlight.

Front

How often do total solar eclipses occur on average?

Back

Every 18 months on average.

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, and it passes through the vertex.

Front

How do you find the axis of symmetry for a quadratic equation in standard form?

Back

The axis of symmetry can be found using the formula x = -b/(2a), where a and b are coefficients from the quadratic equation ax^2 + bx + c.

Front

What does the y-coordinate of the vertex represent in a quadratic function?

Back

The y-coordinate of the vertex represents the maximum or minimum height of the object modeled by the quadratic function.

Front

What is the significance of the x-intercept in a quadratic function?

Back

The x-intercept(s) represent the point(s) where the object reaches the ground (height = 0).

Front

How do you determine when an object reaches its maximum height in a projectile motion problem?

Back

You find the axis of symmetry and then substitute that value back into the equation to find the maximum height.

Front

What is the general form of a quadratic equation?

Back

The general form of a quadratic equation is y = ax^2 + bx + c.

Front

What does the term 'parabola' refer to in mathematics?

Back

A parabola is the graph of a quadratic function, which is U-shaped and can open upwards or downwards.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the graph of a quadratic function, depending on the direction the parabola opens.
