Answer:
Step-by-step explanation:
You are being asked to compare the value of a growing infinite geometric series to a fixed constant. Such a series will always eventually have a sum that exceeds any given fixed constant.
__
<h3>a)</h3>
Angelina will get more money from the Choice 1 method of payment. The sequence of payments is a (growing) geometric sequence, so the payments and their sum will eventually exceed the alternative.
__
<h3>c)</h3>
For a first term of 1 and a common ratio of 2, the sum of n terms of the geometric series is given by ...
Sn = a1×(r^n -1)/(r -1) . . . . . . . . . . series with first term a1, common ratio r
We want to find n such that ...
Sn ≥ 1,000,000
1 × (2^n -1)/(2 -1) ≥ 1,000,000
2^n ≥ 1,000,001 . . . . add 1
n ≥ log(1,000,001)/log(2) . . . . . take the base-2 logarithm
n ≥ 19.93
The total Angelina receives from Choice 1 will exceed $1,000,000 after 20 days.
The right answer is
D.)
Hope this helps :)
Answer:
y-intercept = 275
x-intercept = 125
Step-by-step explanation:
The y-intercept is the point on your line where x=0. On this line, the y-intercept is the point (0,275) (x,y)
The x-intercept is the point on your line where y=0. On this line, the x-intercept is the point (125,0) (x,y)
Answer:19/20
1-20=19
1÷20=0.05
0.05=5%
I hope this is good enough:
