Answer:

<h3>Part A</h3>

The x-intercepts are reflecting zero-profit: (0, 0) and (6, 0).

The maximum value of the graph is at vertex (3, 120): maximum profit when the price is $3.

The function is increasing until the vertex, between x-value of 0 to 3 and is decreasing once it reached the vertex, between x-value of 3 to 6.

In the first interval the sale and profit increases, in the second interval the sale and profit decreases.

<h3>Part B</h3>

<u>Average rate of change from x = 3 to x = 5 is:</u>

  • (f(5) - f(3))/(5 - 3) =
  • (60 - 120)/2 = -30

This represents the profit drop of $30 per $1 price increase when price changes from $3 to $5.

<h3>Part C</h3>
  • The domain is representing the price. It should be profitable so it is between $0 and $6.

5. A gardening club has 21 members, of which 13 are males and the rest are
Misha Larkins [42]

If you know that there are 21 members and 13 are females, if you subtract 13 from 21, you will get 8. There are 8 females in the gardening club.

Now you have to figure out the ratio to females to all club members. You already know that there are 8 females and 21 club members. The ratio would be 8:21.

I hope you found this helpful :)

James is participating in a 5-mile walk to raise money for a charity. he has received $200 in fixed pledges and raises $20 extra
Firlakuza [10]
The standard formula of a point-slope equation is (y-y1) = m(x-x1). So, we would arrange the final equation in this way as much as possible. Let y be the total amount her receives and x be the number of miles. That would be

y = 200 + 20x
y = 20 (10 + x)

That would be the equation. If he finishes the walk,

y = 20 (10+5)
y = $300

he would receive a total of $300.
