If you are rounding to the nearest tenth
Let's say round 20.15 to the nearest tenth. 1 is the tenth place. You have to look at the hundredths place. Since it is 5 and over You round up. If it is under 4 then you round down to it would be 20.2
Answer:
-3 (D+5)
Step-by-step explanation:
Problem: -3D -15
what you do is find the highest number each one is divisible by.
In this case they can both be divided by -3.
Bring it out of the parenthesis and leave the rest inside
Thus leaving -3 (D+5)
The midpoint formula is basically just the average of the two points. Here it is:

Then, you plug the points in. The answer is (-13,-5/2) or
C
From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

Hence, the distance is 250×30=7500 ft
3x - 9x = -21 + 4
-6x = -17
x = -17/-6
x = 17/6
