Answer:
n stands for the unknown number
Step-by-step explanation:
It's the only variable in the equations, so it is the only one that can stand for any unknown.
Formula is: h = vi · t + 1/2 g · t²
For the final position ( on the ground ): h = - 255 ft
vi = - 21 ft/s, g = -9.81 m/s² = - 32.174 ft/s²
- 255 = - 21 t - 1/2 · 32.174 t²
16.087 t² + 21 t - 255 = 0
t 1/2 = ( - 21 +/- √ (441 + 16,408.74 ))/ 32.174 =
= ( -21+/- 129.8 ) / 32.174 = 108.8 / 32.174 = 3.38 s
Answer: The ball hits the ground after 3.38 s.
Somewhat true but I need more information to this problem
The 26 jar is $0.12 per oz and the 16 jar is $0.15 per oz. I think the answer is you save $.03 by buying the 26 oz jar.
