Answer:
4.1 sec
Step-by-step explanation:
h(t)=-3.2t^2+12.8t+1
h(t)=-3.2(t^2-4t)+1
h(t)=-3.2(t^2-4t+4-4)+1
h(t)=13.8-3.2(t-2)^2
For the ball to touch ground, h(t)=0.
13.8-3.2(t-2)^2=0
(t-2)=2.0766
t=4.07≈4.1 sec.
Answer:
Equation: 5w = c
Step-by-step explanation:
![{ \tt{w \: \alpha \: c}} \\ { \tt{w = kc}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7Bw%20%5C%3A%20%20%5Calpha%20%5C%3A%20c%7D%7D%20%5C%5C%20%7B%20%5Ctt%7Bw%20%3D%20kc%7D%7D)
k is a constant of proprtionality
![{ \tt{1 = (k \times 5)}} \\ { \tt{k = \frac{1}{5} }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B1%20%3D%20%28k%20%5Ctimes%205%29%7D%7D%20%5C%5C%20%7B%20%5Ctt%7Bk%20%3D%20%20%5Cfrac%7B1%7D%7B5%7D%20%7D%7D)
» Therefore, equation becomes:
![{ \tt{w = \frac{1}{5}c }} \\ \\ { \boxed{ \tt{5w = c}}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7Bw%20%3D%20%20%5Cfrac%7B1%7D%7B5%7Dc%20%7D%7D%20%5C%5C%20%20%5C%5C%20%7B%20%5Cboxed%7B%20%5Ctt%7B5w%20%3D%20c%7D%7D%7D)
