Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.
A polynomial is an expression that consists of variables (or indeterminate), terms, exponents and constants. For example, 3x2 -2x-10 is a polynomial.
Step-by-step explanation:
<u>In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7</u><u>.</u>
Answer :
R = 6.25%
Solution,
Let P is the principal. It means interest will be :
I=3/8 P
The formula for the interest is given by :
Hence, the rate of interest is 6.25%.
Answer:
No
Step-by-step explanation:
To find out, all we need to do is plug in 9999 into the sequence.
By completing the square, we get . 1001 is not a perfect square, which means that 9999 is not in the sequence.
hope this helped! :)
