Answer:
well I actully you do 17,125 times 3 and then you get your answer
Step-by-step explanation:
17,125 times 3
The answer is D.
Hopefully this helps! :)
145 = -16 t² + 80 t +s
s = ?
v = v0 - at
0 = 80 - at
80 = at
s = 80 t - at²/2
s = 80 t - 80t/2
s = 40 t
Finally: 145 = -16 t² + 80 t + 40 t
16 t² - 120 t + 145 = 0
We will solve this quadratic equation:
t = [120 +√ ( (-120)²- 4 · 16 · 145 )] / 32
t = [120 + √ (14400 - 9280) ] / 32
t = (120 + 71.55) / 32 = 5.98 ≈ 6 s
Answer:D) 6 seconds

Answer:
Step-by-step explanation:
Distance formula:

Distance for AB

Distance for AC

2.
same formula solve when positive

Now when it's negative

so y can equal 6 or -2
