Well what I would do first is divide the 900 student by the 445 teacher to get 20 students per teacher. Now I would take that 20 and multiply it by 110 teacher to get 2200 Students.

Answer= C) 2200 Students

Which of the following describes the behavior of the graph shown over the interval (-2,2)?
sergejj [24]

Hello!

We are trying to describe the behavior of the graph given in the question.

To help us understand how to solve this question, we would need to understand <u>concavity.</u>

There are two types of concavity:

  • Concave <em>up</em>
  • Concave <em>down</em>

When a graph is concave up, the slope of the line would look like a "U".

When a graph is concave down, the slope of the line would look like a "U" that is flipped upside down.

In this case, we can see that the graph is concave down.

We can tell that the <em>slope</em> is negative due to the fact that the slope is going <u>down,</u> which results in the graph having a negative slope.

We can also tell that the graph is decreasing due to the fact that the line is doing downward.

Answer:

C). negative and decreasing

Andrew [12]

Answer:

Minimum = \$241786

Step-by-step explanation:

Given

Amount = \$228,100

Commission = 6\%

Required

Determine the minimum Katie will list the house

The given minimum is the minimum she can receive for the house after commission

To calculate the listing minimum, we make use of the following:

Minimum = Amount + Commission * Amount

Minimum = \$228,100 + 6\% * \$228,100

Minimum = \$228,100 + \$13686

Minimum = \$241786

<em>The minimum She can list the house is $241786</em>
