hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t =
and t = - ![\sqrt{175/16}](https://tex.z-dn.net/?f=%5Csqrt%7B175%2F16%7D)
However, as time cannot rewind, we will keep only positive solution
So t = ![\sqrt{175/16}](https://tex.z-dn.net/?f=%5Csqrt%7B175%2F16%7D)
in seconds it will be : 3.3 seconds
The coefficient C-term is 1 in problem. The coefficient is the number before the variable of said equation. Example, the coefficient of X for thus problem 4x-4y is 4 the number BEFORE the variable, never variable itself it won’t ever be 4x
Answer: If you're not vegetarian, then you do not eat beef.
Step-by-step explanation:
Dismiss the 'if' and 'then':
- you do not eat beef
- you're not vegetarian
Now, all you have to do is switch their places:
- you're not vegetarian
- you do not eat beef
Now add the 'if' and 'then' back:
If you're not vegetarian, then you do not eat beef.
