(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:B is the answer

Answer:
Step-by-step explanation:
<u>Given</u>
<u>Cross multiply and solve for x:</u>
w + 4
------------------------
l l
l l w
l l
------------------------
Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14
