Answer:
(x, y, z) =(1, -1,2)
Step-by-step explanation:
.............
X=20. Because that line is 180 and u subtract 40 and u do 140/7= 20
The answer is 360 in² If you need to see work just tell me :)
The explicit formula for this arithmetic sequence is A(n)=1/2•(-8)^(n-1)
Answer: An = 36 + 2(n - 1)
Step-by-step explanation:
If the height of the tree grows by 2 inches every year, then the height of the tree is increasing in arithmetic progression. The The formula for determining the nth term of an arithmetic sequence is expressed as
An = a + d(n - 1)
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 36 inches
d = 2 inches
Therefore, the explicit rule representing this situation is
An = 36 + 2(n - 1)
