Answer:
Step-by-step explanation:
speed=75 miles per hour

distance covered in 10 seconds=110×10=1100 ft
First you would take 312 and divide it by 13. Using that answer and put it over 1. Then times the answer that you just got by twelve. Then put that in a mixed number in its simplest form.
Since you do not want the variable y, you must eliminate 
Therefore, to eliminate it, you must have the opposite of it, making the answer 
Answer:
100
Step-by-step explanation:
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
