A)The formula for the average monthly cellular telephone bill in terms of the year will be A = 80.90(0.914)ⁿ⁻¹
B)The average monthly bill in 1993 willl be $ 61.77
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The formula for the average monthly cellular telephone bill in terms of the year willl be,
A=P(R/100)ⁿ
A = 80.90(0.914)ⁿ⁻¹
The average monthly bill in 1993 is found as ;
n=4 for 1993
A=P(R/100)ⁿ
A = 80.90(0.914)³⁻¹
A=$ 61.77
Hence the formula for the average monthly cellular telephone bill in terms of the year will be A = 80.90(0.914)ⁿ⁻¹ and the average monthly bill in 1993 willl be $ 61.77.

Answer:
You can't really determine anything here, as we'd need to know also the value of F(x)! Check again if there misses anything in this question.
Answer:
The answer is A, $330
Step-by-step explanation:
The generic equation of the circle is given by:

Where,
r: radius of the circle
(xo, yo): center of the circle.
The center of the circle in this case is:

The radius of the circle is:

Substituting values we have:

Rewriting the equation we have:
Answer:
The general form of the equation of a circle with center at (a, b) and radius of length m is:
option A
the answer is 3
because the rise/run ratio is 3/1
