Average national teachers salaries can be modeled using the equation y=9.25(1.06)^n , where y is the salary in thousands of dollars and n is the number of years since 1970A) graph the function
B) using this model, what can a teacher expect to have as a salary in year 2020?
Please help !

Answers

Answer 1

Answer: $y=9.25(1.06)^(n)$
Plug in $n$ to find $y$ .
$n$ would be $50$ because $2020-1970=50$ .

Use order of operations to solve.
$y=9.25(1.06)^(50) \n y=9.25(18.42) \n y=170.39$

Since $y$ is the salary in thousands, multiply $170.39$ by $1000$ .
$170.39*1000=17039$

A teacher can expect to have about $17,039 as a salary in the year 2020.

Answer 2

Answer:

Final answer:

The average national teachers salaries can be graphed by plotting points on a coordinate plane. Using the provided equation, we can calculate the salary for the year 2020 to be approximately $99,460.

Explanation:

To graph the function, we need to plot points on a coordinate plane. We can do this by choosing different values of n and calculating the corresponding values of y. For example, if n = 0, then y = 9.25(1.06)^0 = 9.25. If n = 1, then y = 9.25(1.06)^1 = 9.81. Continuing this process, we can find multiple points and plot them on the graph.

To find the salary for the year 2020, we can plug in n = 2020 - 1970 = 50 into the equation. y = 9.25(1.06)^50 ≈ 99.46 thousand dollars, which is approximately $99,460.

d. 44

Answers

y - (-19) = 25

First, simplify your brackets. / Your problem should look like: $y + 19 = 25$
Second, subtract 19 from both sides. / Your problem should look like: $y = 25 - 19$
Third, subtract 25 - 19 to get 6. / Your problem should look like: $y = 6$

Answer: C) y = 6

3 less the the opposite of the quotient of 10 and -5

Answers

The quotient of 10 and -5 is 10 /-5 = -2.

Opposite of that, opposite of - 2 is -(-2) = 2.

3 less than 2 is 2 - 3 = -1.

So the answer is -1.

A caterer is planning a large dinner party for 385 guests. Each table must seat an equal number of gusts, more than 1 guest and fewer than 20. Determine the number of possible table sizes. If the caterers use 7-person tables, how many tables will they need?-Jarvis

Answers

Answer: The prime factorization of 1001 is 7*11*13, so with the constraint that the tables seat between 2 and 19 guests, we can use tables that seat either 7, 11, or 13 guests.

For tables that seat 7, the caterer would need 11*13 = 143 tables.

For tables that seat 11, the caterer would need 7*13 = 91 tables.

For tables that seat 13, the caterer would need 7*11 = 77 tables
