Answer:
<h2>Amanda needs 72 grams of paint</h2>Step-by-step explanation:
Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.
Now, there remain 3 faces per cube to be painted, which means there are 24 faces.
Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?
Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.
Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the values in the table. In other words, we need to replace
with each value in our given function and simplify.
- For x = 0
Since and
, our first point is (0, -1)
- For x = 1
Our second point is (1, -4)
- For x = 2
Our third point is (2, -5)
- For x = 3
Our fourth point is (3, -4)
- For x = 4
Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
