87 is greater than 13.688
The sequence of squares, , has generating function
Recall that for ,
Taking the derivative, we have
and taking the derivative again, we have
From this we can get an expression for in terms of the derivatives of :
Then
Answer:
you can approximate it to 61°
First see if there is a constant rate of change...
(344.8-346)/(2-0)=-0.6
(343-344.8)/(5-2)=-0.6
So the rate is constant which means this is just a line of the form y=mx+b
m=-0.6 and since we see that (0,346) we know the y-intercept, "b", is 346 so our line is:
y(x)=-0.6x+346
y(4)=343.6 ft
y(9)=340.6
