Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =

Common ratio =

The common difference applies to the other given numbers for example :

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
Answer:
48,000
Step-by-step explanation:
320,000÷100=3200
1/100=3200
×15=48,000
therefore 15/100=48,000
Answer:
Please see attached graph
Step-by-step explanation:
We know that the equation tht represents the boats avlue is given by
A(x) = 400(b)^x + 0 = 400(b)^x
A(x) = 400(b)^x
An increment in the rate of 25% a yeard is given by
b = 1.25
A(x) = 400(1.25)^x

C.(-1,3) B.(0,2) A.(2,5) :)
The total amount of her purchase before tax was added is; $52.46
<h3>How to calculate discounted amount?</h3>
We are told that the percentage sales tax she paid on her purchase was 8.75% which translated to an amount of $4.59.
Now, let the amount of her purchase be x. Thus;
8.75% * x = $4.59
x = 4.59 * 100/8.75
x ≈ $52.46
