\begin{gathered} a)P=30000(1+0.05)^n \\ b)\$62,367.00 \end{gathered}

1) Iteration means a repetition of a rule.

a)

Considering that we have the following data:

Rate of increase: 5% per year

-

2) Then we can write out the following:

P=30000(1+0.05)^n

Plugging into n, the number of years we'll have:

Profits: $30,000 1st year

P: $31.500 2nd year

$33075 3rd year

(...) (...)

b) Since we want to know the predicted profit 15 years from the first year, then we can plug for that:

\begin{gathered} P=30000(1+0.05)^{15} \\ P=\$62,367.00 \end{gathered}

Note that we have plugged into n, n=15 years. Since the first year was $30,000 the profits.

Ln how many ways 5 person sitted in a round table having 8 seats?
kvasek [131]

Answer: First consider the case that ‘just’ 5 persons are seated around a round table.

Clearly, ‘just’ 5 persons can be seated around a round table in (5 - 1)! = 4! = 24 ways.

Now, one vacant chair is to be inserted among them.

Say, for a particular sitting arrangement ‘ABCDE’; there are 5 scopes available for inserting the vacant chair - between A and B, between B and C, between C and D, between D and E & between E and A.

So, there are 5*24 = 120 ways available that 5 persons can sit around a round table with 6 chairs.

Step-by-step explanation:

How many solutions are there to the equation below?<br><br> 12x+6=5x
slavikrds [6]

Answer:  There is one solution to the given equation.

Step-by-step explanation:  We are given to find the number of solutions to the following equation :

12x+6=5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Since the given equation is linear in one variable x, so it will have only one solution.

The solution of equation (i) is given by

12x+6=5x\\\\\Rightarrow 12x-5x=-6\\\\\Rightarrow 7x=-6\\\\\Rightarrow x=-\dfrac{6}{7}.

Thus, there is one solution to the given equation.
