Answer:2 or 2/1
Step-by-step explanation:
Start a 0
Count up until the line perfectly hits in the center of the lines
From the given function, to explain the correct answer I will plot the graph for :
y(t)=-t^2+14t-40
thus the graph will be as shown in the figure:
From the graph we deduce that the correct statement is:
y'(t)=-2t+14=0
thus
t=7
thus
y(7)=0
thus the correct statement is:
<span>c. The average rate of change over the interval 6≤t≤8 is 0</span>
Answer:
85
Step-by-step explanation:
425 divided by 8= 85
The slope would be 3.
7-1=6
2-0= 2
6/2=3
