Best ResponseYou've already chosen the best response.0(h(t)=16t^2+vt+c where h is the approximate height in ft t is the time in motion in seconds v is the initial upward velocity in ft per second and c is the initial height in ft) A baseball player hits a pitched ball when it is 4ft above the ground the initial upward velocity is 80ft/s how long will it take for the ball to hit the ground???

Best ResponseYou've already chosen the best response.0im stuck on the step with the quadratic formula

anonymous

Best ResponseYou've already chosen the best response.0So what is the initial velocity?

anonymous

Best ResponseYou've already chosen the best response.0Plug that in for v. What is the height above the ground? Plug that in for c.

Best ResponseYou've already chosen the best response.0\[0 =at^2 + bt + c \implies t = \frac{(b) \pm \sqrt{(b)^2  4(a)(c)}}{2(a)}\]

anonymous

Best ResponseYou've already chosen the best response.0tell me exactly how 2 put it in my calculator cuz everytime i do i get large #'s and yes i put divide y 8

Best ResponseYou've already chosen the best response.0Start with the part under the square root

anonymous

Best ResponseYou've already chosen the best response.0so dont put 20 first

anonymous

Best ResponseYou've already chosen the best response.0What do you get for that part

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Now take the square root of that

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, now you have 2 solutions: \[x = \frac{20 \pm 20.3}{2(4)}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Oh, and you didn't round up.. I think it's 20.396 or 20.4

anonymous

Best ResponseYou've already chosen the best response.0im still getting 50.75

anonymous

Best ResponseYou've already chosen the best response.020 + 20.4 = ? 20  20.4 = ?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok so u dont multiply the 20 to the 20.4/8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No, you add and subtract them

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0(20 plus or minus 20.4) / 8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0There's one more possibility.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0But the other one is positive

anonymous

Best ResponseYou've already chosen the best response.0ok i got u now wow thanks but its weird how i cant put the whole thing in the calculator

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Because the order matters

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Plus plugging the whole thing in at once makes it harder to find where you made your mistake. Just put in each piece at a time.

anonymous

Best ResponseYou've already chosen the best response.0ok can u help me wit another one

Best ResponseYou've already chosen the best response.0using the same formula a flare is launched from the deck of a life boat 4ft above the water surface the initial upward velocity is 80ft/s after how many seconds will the flare be 100 ft above the water surface

anonymous

Best ResponseYou've already chosen the best response.0So how would you set this one up?

anonymous

Best ResponseYou've already chosen the best response.0h(t)=16t^2+vt+c where h is the approximate height in ft t is the time in motion in seconds v is the initial upward velocity in ft per second and c is the initial height in ft

anonymous

Best ResponseYou've already chosen the best response.0i got 100t=16t^2+80t+4

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0it's just 100, h is the height.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so \[100 = 16t^2 + 80t + 4\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0move the 100 to the other side so it equals 0 and then use the quadratic formula again.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0by subtracting 100 from both sides that is

anonymous

Best ResponseYou've already chosen the best response.04100 is 196, not positive

Best ResponseYou've already chosen the best response.0well den dis aint working now idk u do it

anonymous

Best ResponseYou've already chosen the best response.0You did it right, I don't know how, but 3 is one answer. There is another answer

anonymous

Best ResponseYou've already chosen the best response.0If you used 4t^2+20+24 You should have gotten (1 and 6) though

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0But the correct formula 4t^2+20t24 = 0 gives one of the solutions being 3 and the other being 2

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0the answer can only be 1s or 2s,3s

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0\[0=4t^2 + 20t  24 \implies t = \frac{20 \pm \sqrt{20^2  4(4)(24)}}{2(4)}\]

anonymous

Best ResponseYou've already chosen the best response.0ok i got dat but now getting big numbers again

anonymous

Best ResponseYou've already chosen the best response.0Do the part under the square root first

anonymous

Best ResponseYou've already chosen the best response.0and the square root of 16 is?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Ok, and what's the denominator? 2(4)

anonymous

Best ResponseYou've already chosen the best response.0polpak, i have some confusion. check your equation once again

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So you have two solutions: (20 + 4)/8 and (20  4)/8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0for the first one you have 16/8 and the second is 24/8

anonymous

Best ResponseYou've already chosen the best response.0ok linda dis is my question create ur own i need help 2 get off mines

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0no, its alright now. i don't how but the latex code was not properly loaded and the \[4t ^{2}+20t24 \] was looking like \[4t ^{2}20t24 \]

Best ResponseYou've already chosen the best response.0i cant do \[\sqrt{21}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so how do i do dis problem

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0it is a imaginary number!!!! it will come \[i \sqrt{21}\]

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0no, it ain't right. i is nothing but an imaginary number. it can not be solved. it has to be written i only.

anonymous

Best ResponseYou've already chosen the best response.0your solution seems wrong!!!

anonymous

Best ResponseYou've already chosen the best response.0do you want to write this equation???

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i know the answer has 2 be 1 or 1.65 but idk y it aint working

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0still something wrong in the equation. there is no "t"

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yes, the equation is giving t = 1 and o.5

Best ResponseYou've already chosen the best response.0how uget dat did u use the quadratic formula

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0how cuz i got 41/8 + or  5

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0you must be wrong cuz i used calculator to solve.

anonymous

Best ResponseYou've already chosen the best response.0i know dat wat numbers did u end up wit

anonymous
