49x^2 + 64y^2 = 3136 . . . (1)
y - 6 = (1/4)x^2 . . . (2)
From (2), x^2 = 4(y - 6) = 4y - 24 . . . (3)
Putting (3) into (1) gives
49(4y - 24) + 64y^2 = 3136
196y - 1176 + 64y^2 = 3136
64y^2 + 196y - 4312 = 0
y = 6.819
x = sqrt(4(6.819) - 24)
x = 1.81
The possible point of collision is (1.81, 6.819)
Answer:
Step-by-step explanation:
All of these equations are in the 
form.
stands for the slope (or gradient) of the line (how steeply it goes up or down) and 
stands for the y value where the line crosses the y-axis (also known as y-intercept).
With this in mind, it's evident that the slope of is 4 and that it crosses the y-axis when y is equal to -3.
Good luck!
