Answer:
C(t)=30+3.5t
Step-by-step explanation:
Time increases by 2, the average difference in the cost is approximately 7.
So if d is the common difference of the function modeling this relationship, then 2d≈72.
Therefore, d≈ 7/2 = 3.5
Since the initial cost of the land is 30 thousand dollars, the function that best models its cost t years since 1990 is C(t)=30+3.5t
Answer:
C(t)=30+3.5t
Step-by-step explanation:
Yeah this is the answer

Answer:
f(-)8=0
Step-by-step explanation:
an = a1 +d(n-1)
a4 =a1+d(4-1)
-4 = -1+d(3)
add 1 to each side
-3 = 3d
d= -1
an = a1 +d(n-1)
an = -1 +-1 (n-1)
an = -1 -n +1
an = -n
Choice D
Number one is 4^3
Number two is 2.6^4
