13. Find h in terms of t: dh
= t4 – t3 + t2 + t + 1 and h
26
==
250
when t = 2
dt​

Step-by-step explanation:

3t^3 - 3t^2 + 2t + 1 = 26

3 (2)^3 - 3 (2)^2 + 2 (2) - 25

3 (8) - 3 (4) + 4 - 25

24 - 12 +4 + 1 - 25

= 8

17h = 250

h = 14.71

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
