Answer:
The answer would be -9 and -3 which would be B and D
Step-by-step explanation:
Answer:
A). 101 inches
B). 110 years
Step-by-step explanation:
Years since planting Circumference Difference
1 3 -
2 5 (5 - 3) = 2
3 7 (7 - 5) = 2
4 9 (9 - 7) = 2
5 11 (11 - 9) = 2
6 13 (13 - 11) = 2
There is a difference of 2 in every successive term of the circumference.
Therefore, the given sequence is an arithmetic sequence.
Explicit formula of an arithmetic sequence is given by,
Here a = first term
n = number of terms
d = common difference
From the given table,
Here = circumference after 'n' years
n = Age of the plant
By this formula,
Circumference of a tree after 50 years,
= 101 inches
Age of tree with the circumference = 221 inches,
221 = 2n + 1
2n = 220
n = 110 years
Answer:
- face: hemisphere
- hat: cone
Step-by-step explanation:
The diagram shows a cone atop a hemisphere. We associate the cone with the hat (because it is on top), and the hemisphere with the face.
The shapes use are ...
face: hemisphere
hat: cone
