The answer is the first choice, 3(w-4)=5.
3 times = 3
a number minus four = (w-4)
is five = 5
I hope this helps.
Step-by-step explanation:
We can see that the function crosses the x-axis at 3 different places, we have x = 1, x = 4 and x = 6 as our roots.
(Note: x = 6 has a repeated root)
There could be complex roots if we know more about the function, but there must be 3 distinct roots.
The best answer here is option A.
Answer:
2.5 seconds since the first ball was hit.
Step-by-step explanation:
The equations that model the heights are:
When the balls meet, both heights are equal, therefore:
-16t² + 56t = -16t² + 156t - 248
-16t² + 56t + 16t² - 156t + 248 = 0
- 100t + 248 = 0
248 = 100t
248/100 = t
t = 2.48 ≈ 2.5
F)x) is shaped like a V with the vertex at the origin so its is one of the choices.
B is also one because its |x| moved up 3 unuts
So is D.
