A light shines from the top of a pole 50ft high. a ball is dropped from the same height from a point 30 ft away from the light.
belka [17]
The speed of the ball is 
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft

50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt

15 POINT 1 QUESTION<br> ITS ALL UP TO YOU!!!!
Anni [7]

First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.

3 + 4x = 5x

we can subtract 4x from both sides to get our final answer,

3 = x, or x = 3. :)
