(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)
Answer:
x = 3
Step-by-step explanation:
Given:
Required:
Value of x and length of segment LM
SOLUTION:
Since M is the midpoint of line segment LN, it implies that:
(substitution)
Combine like terms
Divide both sides by 2
Plug in the value of x
