What is the formula for calculating the volume of a rectangular prism?

Back

V = ℓwh, where ℓ is the length, w is the width, and h is the height.

Front

If the volume of a rectangular prism is 200 cm³ and ℓ = 2w, how can we rewrite the volume formula?

Back

200 = 2w²h.

Front

How can we express height (h) in terms of width (w) for a rectangular prism with volume 200 cm³ and ℓ = 2w?

Back

h = 100/w².

Front

What is the maximum height of a softball modeled by the function h(t) = 3 + 5t - 16t²?

Back

51 feet.

Front

At what time does the softball reach its maximum height according to the function h(t) = 3 + 5t - 16t²?

Back

1.75 seconds.

Front

What does the term 'quadratic function' refer to?

Back

A polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What is the vertex of a quadratic function?

Back

The highest or lowest point of the parabola represented by the function.

Front

How do you find the vertex of a quadratic function in standard form?

Back

Use the formula x = -b/(2a) to find the x-coordinate, then substitute back to find the y-coordinate.

Front

What is the significance of the discriminant in a quadratic equation?

Back

The discriminant (b² - 4ac) determines the nature of the roots: two real and distinct, one real and repeated, or no real roots.

Front

What is the factored form of a quadratic function?

Back

y = a(x - r1)(x - r2), where r1 and r2 are the roots of the function.
