A projectile is launched from a platform 20 feet high with an initial velocity of 72 feet per second, The height h of the projectile at t seconds after launch is given by h = 16t2 + 72t + 20 feet. (a) How many seconds after launch does the projectile attain maximum heigh...
ok got it. thank you. i also solve for y and plug it in right? so i can solve for x.
just a note i now know how to do it but the method to do it will literally take up like 4 pages. if i solve for y=f(x) and use the equation for the curve, k. please tell me im missing something that will make this simpler.
find the point (or points) where the ellipse 9x^2+4y^2=36 has maximum curvature. don't even know where to start with this one.
if (g(x)=x,f(2)=7,and f'(2)=6. what is g'(&)?
