Professor Smith just returned from a conference that was 2, 000 miles east of his home. The steps in the process would be: So, the original equation in the form ax 2 + bx + c has been transformed into the vertex form (x + h) 2 + k where ( -h, k) represents the coordinates of the vertex. Classroom Activities. To find the time it takes for the ball to return to the ground, first students must set the function equal to zero because the height of the ball on the ground is zero.

One problem should focus on perimeter, one on area, and the third on volume. So, -4t = 0 when t = 0 and 4t - 13 = 0 when t = 13/4. The problem suite begins with students practicing writing projectile motion equations. 4.5 quadratic application word problems answers key. In this group, students must figure out what variable they are looking for and then use the result to answer a question. Finally, when they have mastered the art of writing area and volume equations, and they are adept at solving them, I can continue on my personal mission by having students study the effects of dilations (increasing or decreasing dimensions by some multiple) on perimeter, area, and volume. In recent years I have taught primarily tenth grade students in either Level 2 or Level 3 of our integrated math program. If Rick kayaked at a speed of 5 mph, what was the speed of the current?
