Using the given equation, set H to 8 meters and solve for t:
8 = 3 + 20t -5t^2
Subtract 8 from each side:
3 + 20t -5t^2 -8 = 0
Simplify:
20t - 5t^2-5 =0
Factor out -5:
-5(t^2-4t+1)=0
Divide both sides by -5:
t^2 - 4t +1 = 0
Using the quadratic formula solve for t:
t = 2 +/- √3
t = 3.73 or 0.27
Answer:
Step-by-step explanation:
Here we have an implicit function, and so we must use implicit differentiation to find dy/dx.
(d/dx)(3y² - 6 = x) results in 6y(dy/dx) - 0 = (dx/dx), or 6y(dy/dx) = 1.
Then the desired derivative is
1
(dy/dx) = ---------
6y
