Answer:
<em>Option B, Option D</em>
Step-by-step explanation:
If we are to take a look at these points, we would see that they share a common y point on the y - axis ⇒ -5;
This would mean that a horizontal line runs through the following points ( 4, -5 ) and ( 6, - 5 ), and provided it is a horizontal line, it has no slope, or in other words a slope of 0;
<em>Solution; Option B, Option D</em>
Substitute the value 350 in for your velocity:
350 = 20 * sq rt(273+t)
divide both by 20 --> 17.5 = sq rt(273 +t)
square both to cancel out the sq rt --> 306.25 = 273 +t
then just subtract 273 from both to get 33.25 = t
