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
Answer: I can use variables to represent the coordinates of the vertices for a general triangle ABC. then I can calculate the midpoints of the sides in terms of the same variables, and calculate the slope of each midsegment showing that the expression for the slope of a midsegment is the same as the expression for the slope of the third side of the triangle proves that the two are parallel.
Step-by-step explanation: this is word for word btw!
Answer:
fortnite
Step-by-step explanation:
im different
You wanna
divide 85 and 52
because he can run 20 KM in 85 min
and he wants to see how long it takes him to run 52 KM
So the first one is correct
