The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
Answer:
x=13i, -13i
Step-by-step explanation:
Take the square root of both sides which gives you plus or minus the square root of -169. Then you get plus or minus 13times the square root of negative 1. Now you can say that x equals positive or negative 13i
Answer:
Yep thats right
Step-by-step explanation:
Answer:
with a line accross the points
Let the total cost of the meal be = x
Let Emily pays the smaller ratio or amount.
Emily's dad pays = 52.20
Emily and her dad share in the ratio = or 2:3
The given ratio means that Emily pays of the total and dad pays of the total.
As dad paid 52.20 so,
Hence, total cost of the meal is £87 and Emily's share is £34.80
