The line is parallel to y axis
We know that if a line is parallel to y axis
So there is no slope
Here it has constant x value as -2
So the equation is
Option A
A(n) = a₁.(r)ⁿ⁻¹, where a₁ = 1st term, r= common ratio and n, the rank
In the formula given a₁ = 5, r = 3/2 and n = 6 (we have to find the 6th term value).
a₆ = 5.(3/2)⁶⁻¹ = 5.(3/2)⁵ = 1215/32 (answer C)
Answer: -4 . 2ⁿ⁻¹
Step-by-step explanation: This is a geometric progression
the nth term is given by arⁿ⁻¹
a = the first term of the sequence
r = common ratio
n= number of terms
for this sequence
a = -4
r = -8/-4 = 2
nth term, an = -4 . 2ⁿ⁻¹
9 because the square root of 81 is 9
Answer:
The better deal is 10 cans of soda for $5.50
Step-by-step explanation:
- 6 cans of soda for $3.60 means each can of soda is worth .60 cents
- 4 cans of soda for $2.36 means each can of soda is worth .59 cents
- 10 cans of soda for $5.50 means each can of soda is worth .55 cents
Therefore, 10 cans of soda for $5.50 is the best deal because you are getting the most cans of soda for the cheapest amount of money.
Hope this helped!
