A) h'(t) = -32t + 40 = 0 -32t = -40 t = 5/4
Test if it's max or min: h" = -32 < 0 therefore it's max
B) The ball's maximum height therefore occurs at t = 5/4 and the height is: h(5/4) = -16(5/4)^2 + 40(5/4) +6
wait i dont get what you are doing in the first slide
Taking the derivative of the function.
Did you take calculus?
Yah but you cant square the 32 yet you have to find the t first
no this is Algerbra advance
sorry nanas.. I am doing everything correct, but I don't know how to do this using algebra. Wait actually if u use algebra, just plot the graph.. look at it's highest point, x-value will be the time and y-value will be the height.. This is a parabola pointing down..
I was using calculus and my method works too, but if u don't know it i can just give u answers..
I tried that i guess my brain is to advanced lol no I dont get how to plo the points but the anwser would be fine
i mean how to plot
just type in the equation and then use trace.. well the answers would be: A) 5/4 B) -16 * (5/4) ^2 + 40 * (5/4) + 6 <=whatever that equals.. sorry don't feel like doin arithmetic right now.. i actually gotta go to bed lol got a class early 2morro..
t = 10 secs
wow what time is it there
vijay can't be..
wow its only 7 30 here
vijay t = 10 secs doesn't make sense.. it's t = 5/4
if u use equation v=u+ft v=0, u=40, f= -10, t= ?
ok What is the lil star thing
he is asking maximum height..
little star is multiplication
time at max height..
1st find the time, then plug the t into the function, u will get height
bahrom is right i remember my online teacher saying this
oh so all i got to do is the multiplication
Okay here's proof: At t = 10; h = -16*(10)^2+40*10+6 = -1600 + 400 + 6 is less than 0.. u can't have a negative maximum height.. the ball is still in the air..
yeah just plug in 5/4 for t in the h(t) equation and find the answer..
Please click on become a fan if I helped, I really want to get to the next level!! Thanks =) I'm off..
