Customers of a phone company can choose between two service plans for long distance calls. The first plan has no monthly fee but
hram777 [196]

Answer:

\\x= P/(c -d)[/tex],

Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge  of additional $d for every minute.

Step-by-step explanation

Assume that the price of each minute in the first plan is $c and that the second plan charges a flat rate of $P and a charge  of additional $d for every minute.

Thus, the monthly cost of a customer who consumes x minutes in each plan is:

For the first plan: cx

and for the second plan: P + dx

Considering that the monthly costs must be the same in each plan, you have to:

cx = P + dx\\ transposing terms\\cx - dx = P\\   applying common factor\\(c -d)x = P\\ dividing by [tex]c - d

\\x= P/(c -d)[/tex].

For example if c = $2; d = $1 y P = $10, Then the number of minutes would be, x=10  and the total cost for each plan would be $20

Evaluate 0.985 using the Binomial Theorem. Write 0.98 as a binomial: (1 -0.02 ) Enter the value for each variable. a
kati45 [8]

Using binomial theorem. The value of 0.98^5 is 0.9039207968.

|Using the binomial theorem, we get

0.985 Co(1)5 +5 Ci(1)'(-0.02)1 +5 Ca(1"(-0.02) +5 Ca(1)P(-0.02)3 +5

C(1)(-0.02)+5 Cs(1)°(-0.02)

0.98=(1) + 5(-0.02)'+ 10(-0.02)? + 10(-0.02)3 +5(-0.02) + 1(-0.02)5

0.98 (1)+(-0.1) + (0.004)+ (-0.00008) +0.0000008+ (-0.0000000032)

0.98-0.9039207968.

The binomial theorem, the statement that for any positive integer n, the sum of two numbers a and b raised to the power n can be expressed as the sum of n + 1 terms of the form Yoki's triangle.
