Answer:
-12
Step-by-step explanation:
ds/dt = d/dt ( 1-12 t)
ds/dt = -12
When t=2
ds/dt = -12
3.4×10⁻¹⁴ × 1.8×10²⁸
= (3.4 x 1.8) x 10⁽⁻¹⁴⁺²⁸⁾
= 6.12 x 10¹⁴
Answer is A.
Hope it helps!
Answer:
No, it is not a function because one of the x values have two different y values
Let x = hours to meet

210 + 105x = 135x
30x = 210
x = 7 hours to meet
