Vika [28.1K]
First off, 23+12 isn't 45.

Anyways, Part A, graphing should be pretty simple, just match the corresponding values together as shown by the table on the left. For example, for the crop size that says "200," go up to where the value is seven, and mark it. 

The function is also not that hard. Make "x" equal the value of the crop size. (Square yards) Thus for "x" crop size, the function B(x) = 3.5/100.

Part B<span>
W(x) = 60*x

</span>For the completing the table, just plug in some values for "x" (remember "x" is "Bushels of corn in a shipment") like 1, 2, 3, 4 etc, and write the corresponding output next to it.

Part C
The given information literally tells you the answer. P(x) = 4x. That's ur function. So for the graph, say "x" ("Bushels of Corn") is 1, than the corresponding "y" value ("Selling Price") is 4, since P(x) = 4*x. 
<span>
As for completing the table, once again, just write in several values, geez. For example, "Bushels of Corn" = 5, than "Selling Price" = 20. 

The function basically is the key to all the answers. </span>

Part D
Alright, remember, once you get the function, you have all the answers. 5 Bushels of corn equals 14 gallons of ethanol, so the function is <span>
<span>E(x) = 14/5. (And remember, the "x" value is "bushels of corn")
</span></span>
The table and graph are easy to do, since you know the function, however the "y" axis values on the graph are kind of challenging to deal with, but I have faith that you can estimate and mark the values close enough.<span>

</span>

Here's my best explanation for Part E,<span>

Proportional relationships have graphs that always pass through the origin of a graph, while non-proportional graphs don't. And also, proportional relationships always have consistent ratios, while non-proportional relationships don't. And for their equations, proportional relationships equations are always one step, (Ex: y = 5x) while non proportional equations are two-step equations, which means they contain a constant value that is added or subtracted on the left side. (Ex: y = 3x - 12)</span>

Use the calculator to graph the function y = 2x2 25x + 3. What are the coordinates of the turning point of the graph to the near
professor190 [17]

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{b^2 - 4ac}{4a}

In this problem, the function is given by:

y = 2x² + 25x + 3.

Hence the coefficients are a = 2, b = 25, c = 3, then the coordinates of the vertex are given as follows:

  • x_v = -\frac{25}{2(2)} = -6.25
  • y_v = -\frac{25^2 - 4(2)(3)}{4(2)} = -75.13

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).

katrin [286]

Hello There!

We know that the painter had the steamer from 9 a.m in the morning to 4 p.m in the afternoon

he had it for a total of 7 hours. 28.84 divided by 7 equals 4.12 an hour

Divide $28.84 by 7 hours.

28.84/7 = 4.12

The rental cost per hour was $4.12.
