FLASHCARD QUESTION

Front

What is the maximum height of a ball kicked from a height of 20 feet, modeled by the equation h(t) = 20 - 16t^2 + 32t?

Back

To find the maximum height, use the vertex formula for a quadratic equation. The maximum height occurs at t = -b/(2a) = -32/(2*-16) = 1. Plug t = 1 into h(t) to find h(1) = 20 - 16(1)^2 + 32(1) = 36 feet.

What is the slope-intercept form of a line given two points, O(0,0) and C(6,9)?

Back

The slope (m) is calculated as (y2 - y1) / (x2 - x1) = (9 - 0) / (6 - 0) = 3/2. The equation of the line is y = (3/2)x.

Back

Let s = number of sandwiches and p = number of soups. The equations are: s + p = 18 (total people) and 7.75s + 4.50p = 113.50 (total cost).
