A charged particle is projected in the air such that its horizontal (x) and vertical (y) shifts are given by x(t) = 10t − t2 and y(t) = 6t, where x and y are in meters and time t is in seconds. What is the ratio of y to x at t = 4 seconds?

Question

What's 10*4
What's 4*4

What's $$\frac{6*4}{(10*4)-(4*4)}$$

anonymous · Answer

24

whpalmer4 · Answer

No.

$$\frac{6*4}{(10*4)-(4*4)}= \frac{24}{40-16} = \frac{24}{24} =? $$
