Answer:

Step-by-step explanation:
Where p is the distance from focus to vertex, the equation of the parabola with focus at (0, p) is ...

Your parabola has p=9, so the equation is ...

Answer:
Step-by-step explanation:
The area of a trapezoid is the average of the parallel bases times the height.
A=h(a+b)/2 and since we have two identical trapezoids the total are will be
A=h(a+b) in this case
A=15(32+25)=855mm^2
Answer:
after 4 rule violations he will recieve -100 points. so if total points is 100, then the driver gets 0 points
Ok so first we do 2 + 3 = 5 * 2 = 10 / by 42 = 4.2
other side 36 - 52 = 16 * 4 = 64 now add 4.2 + 64 = 68.2
