B 112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds
Yuliya22 [10]3 years ago
3 0
(350-126)/(5-3)=112m/s

This is the average speed in the time from 3 to 5 seconds...

dd/dt    98,126,154
d2d/dt2   28,28

She actually had a constant acceleration over the entire time period.

The function for that table is:

d(t)=14t^2  

Her actual velocity at any point is v(t)=28t  (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)

3+(4+5) = ( 3+4 ) +5.THIS IS AN EXAMPLE OF THE ---------OF WHOLE
navik [9.2K]

Answer:

D.

Step-by-step explanation:

The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)

x = 2x + 6

x - 6 = 2x

x = -6 (First integer)
