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)
Answer:
PR=22
Step-by-step explanation:
3x+6x+4=14x-6
9x+4=14x-6
10=5x
x=2
Plug in
3(2)
6
6(2)+4
12+4
16
16+6
22
So the bottom should equal 22
14(2)-6
28-6
22
Hope this helps

Ok so you have a equation already solved for a single variable which in this case is y. So just take 6x+2 and sub it in for all the y's in 3y-18x=12 3(6x+2)-18x=12. Now distribute the 3 to get 18x+6-18x=12. Next combine like terms to get 6=12 Now because we cant do anything else and our variable is canceled out and the equality of 6=12 is false the solution to this SoE would be No Solution. <span />
Answer:
Need the rest of the equation
Step-by-step explanation:
For the same reasons as the last problem...
s(n)=20(1-(1/2)^n)/(1-1/2)
s(n)=40(1-(1/2)^n)
But this time we are not starting at one so we must subtract the sum of s(2) from the sum of s(12) so:
40((1-(1/2)^12-(1-(1/2)^2)
40(0.249755859375)
≈9.99 (to nearest one-thousandth)
