question number one is 15 ft
question number two is 7 MI
tbh i forgot how to do the 3rd one
3x2 -3 -x2 +7x -10 =2x2 +7x -13
so thats (2)
Answer:
Step-by-step explanation:
If you plot these points on a coordinate plane, you will see that they both lie on the same horiztonal line, y = -10, with the focus 1/4 to the right of the vertex. This information tells you a ton of stuff. First, it tells you that, since a parabola "hugs" the focus, this parabola opens to the right and is of the form x = y-squared. This equation is

The information also tells us that p (the distance between the vertex and the focus) is .25. h is the "x" coordinate of the vertex and k is the "y" coordinate of the vertex, so h = -1, and k = -10. Filling in our formula:

Simplify the left to
and solve for x:

Answer:84mph there and 42mph back
Step-by-step explanation:do 924 divided by 11 and 924 by 22
D (5x9)x because the parentheses are switched but the values are the same
