The y represents the distance, remember time is the independent variable and distance is the dependent variable.
Another tip, when you see the title, such as distance vs time squared. The first term in the title always goes for the y axis and the second goes for the x axis.
I hope this answers your question!
Answer:
<h3>The 7th term is
1458</h3>
Step-by-step explanation:
For a geometric sequence
U(n) = ar^n - 1
Where
n is the number of terms
r is the common ratio
a is the first term
From the sequence
a = 2
r = - 6 /2 = -3
U(n) = 2(-3) ^ n - 1
For the 7th term
U(7) = 2(-3) ^ 7 - 1
= 2(-3)^6
The final answer is
= 1458
Hope this helps you
It is necessary when you are getting into multiplying from the outside of parenthesis and multiplying variables inside of parenthesis.
ex: 5(3 + 3x)
5 * 3 = 15
5 * 3x = 15x
so final set up would be 15 + 15x
The common difference is x
the first term is x+1
a_8 = x+1 + x(8-1) = x+1 + 7x = 8x + 1
