Homework
For the homework, solve the following math problems. All the problems should be solved algebraically where possible (i.e. not by simply graphing and observing).
- Plot the line y=(6/9)x+3.
- Determine whether the following points are on the line y=(6/9)x+3:
- (-2,1)
- (3,5)
- Find the point of intersection of the lines y=(6/9)x+3 and y=2x+7.
- Determine whether these two line segments intersect and where: (0,7)--(4,15) and (-6,-1)--(6,7).
- Find the equation of the line that is perpendicular to y=(6/9)x+3 and intersects it at x=3.
- Find the midpoint between (-5,-3) and (0,7).
- Find the perpendicular bisector line segment to make a "perfect X" with line segment (-5,-3)--(0,7) (here, perfect X means both line segments are same length).
- Find the closest point on the line y=(6/9)x+3 to the point (5,2).
- Find the distance between the point (5,2) and the line y=(6/9)x+3.
- Determine whether the circle of radius 5 at (5,2) intersects with the line y=(6/9)x+3.
- Determine whether the circle of radius 5 at (5,2) intersects with the line segment (6,7)--(12,11).
- Find points of intersection between the circle of radius 5 at (5,2) and the line y=(6/9)x+3.
- Find the value that is 20% on the way from 69 to 420.
- Find the point that is 69% from (6,9) to (4,20).
- Find the color C3 that is a blend 69% from C1 (42,230,156) to C2 (200,60,200).
- You have a horizontal UI slider that has an x range of 223 to 273. It controls a strength value ranging from 5 to 100.
- Find the mathematical function that computes the strength value given the x position of the slider.
- The damage value for an attack is calculated as dmg=(3/2)str+10. Find the function that computes attack damage given the slider position.
