***Use the Practice II page in the tutorial above to complete the following. Paste the equation onto the page. Print your quiz when finished and attach the work from number 4. We are practicing the calculator above. Please do not just type the answer in word. You may answer each other’s questions, but you may not both type the same equations for number 4.
1) A rock is located 4 feet North and x feet West of the origin. A tree is 5 feet South and 3 feet East of the origin.
Type the coordinate points for each.
Find the distance between the points. (Yes, your answer will be an expression which includes the variable x.)
Find the midpoint between the points.
2) Type the equation for a parabola with the vertex at (8,6) and focus (2,6).
3) The plan for a park puts the center of a circular pond of radius 0.6 mile at 2.5 miles east and 3.8 miles south of the park headquarters. Type an equation to represent the boarder of the pond, using the headquarters as the origin.
4) You may only use each type of equation once: circle, line, absolute value, square root, cubic root, cubic, exponential, power, parabola with x squared, and parabola with y squared.
a. Type two equations with no intersection.
b. Type two equations with one intersection.
c. Type two equations with two intersections.
d. Type two equations with three intersections.
e. Type two equations with four intersections.
f. When is it possible to have 5 or more intersections?
g. Solve each algebraically by hand and show your work.
