f(x)=\dfrac{x}{2}-3=\dfrac{1}{2}x-3\\\\g(x)=4x^2+x-4\\\\(f+g)(x)=f(x)+g(x)\\\\(f+g)(x)=\left(\dfrac{1}{2}x-3\right)+(4x^2+x-4)=4x^2+1\dfrac{1}{2}x-7

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
