Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.

Answers
Answer:
$12.80
Step-by-step explanation:
The cost to get 8 bottles of juice and 4 bags of chips will be:
= 8($.105) + 4($1.10)
= $8.40 + $4.40
= $12.80
The cost for x bottles of juice and y bags of chips will be:
= (1.05 × x) + (1.10 × y)
= 1.05x + 1.10y

Which of the following figures in a plane separates it into half-planes is a line. In addition, a line is the only given entity or object that can elicit an unlimited and infinite figure to separate the given assumed limitless plane thus, it will unceasingly divide the plane endlessly if given that the plane is unknown in measure and length. For example, a given figure of rectangle with an unknown length or measure, the only figure that can divide itself is the line perpendicularly speaking in its shape or position of the line.
Answer:
F. A line
Step-by-step explanation:
