The question can be answered using the exponent function. The function would look like:
an = a1 (r)^(n - 1)
where
a1= initial payment
r= ratio of increase
n= number of payment.
The sigma notation to determine the sum of
15 Σ = 150*1.3^(n-1)n = 1
Since the function ratio is 1.3 which was >1, the series will keep increasing so it would be divergent
Answer:
bradyn graphs a line that passes throw the origin. what do you know ... do you know about the y-intercept of each student graph? explain your answer ... a straight line D- no because the graph does not go through the origin.
Step-by-step explanation:
If r(x) is an inverse of s(x), then we know that r(s(x)) = x and s(r(x)) = x.
Let's think about what inverses are in order to help us understand.
We know that a function, in order to be an inverse of another, has to be reflected about the y = x line.
So, if a function is reflected about the y = x line, then if we have a composite function, they will always result in the same input (ie x)
<u>Answer</u>
$1,400
<u>Explanation</u>
The original price = 100%
After the discount the selling price = (100-25)=75% of the original price.
75% ⇒ $1050.00
100% ⇒ ?
From here you cross multiply
Original price = (100% × $1050.00)/75%
= 105,000/75
= $1,400
The correct answer is -20
