If you are asking what is the graph of y = 3x^2 -2x+1.
Then, the attached file would be the answer.
To check, b^2 - 4(a)(c), for each equation and use these facts:
If b^2 - 4(a)(c) = 0, there is only one real root meaning, the graph touches the x-axis only in one point.
If b^2 - 4ac > 0, there are two real roots meaning, the graph touches the x-axis in two different points.
If b2 - 4ac < 0, there are no real roots then the graph does not touch the x-axis. This would be the case for y = 3x^2 - 2x + 1.
Solution:
(-2)^2 -4(3)(1) = 4 - 12 = -8 < 0 will result in not real roots.
Answer:
<h3>The solution is 480 bricks.</h3>
Step-by-step explanation:
We are given that number of rows of bricks in a wall = 15 rows.
Number of bricks in a row = 32 bricks.
In order to find the total number of bricks, we need to multiply number of rows with number of bricks in a row.
Total number of bricks in 15 rows = 15 × 32 = 480 bricks.
Therefore, will Chin-li will need 480 bricks.
<h3>The solution is 480 bricks.</h3>
Answer:
4 + 12 × 19 + 24
Step-by-step explanation:
Hullo!
Words like "added or sum", represent addition.
Words like "times", represent multiplication.
Words like "subtracted or took away", represent subtraction.
Words like "divided or split up", represent division.
Therefore, we can express the equation 4 added to 12 times 19 plus 24 can be rewritten as 
in expression format.
Hope this helps!
Based on the measurements of the pool and the path of uniform width, the area of the width and length of the path can be found to be 28.8 meters.
<h3>How to find the width and length?</h3>
First, find the area of the pool:
= Length x Width
= 10 x 26
= 260 meters ²
The area of the path can therefore be found to be:
= Total area of pool and path combined - Area of pool
= 1,092 - 260
= 832 meters²
Seeing as the path has uniform width, that means that the width is the same and the length so the width and length of the pool is:
= √area of the path
= √832
= 28.8
In conclusion, the width and length of the path are 28.8 meters.

Answer: Each bow needs 4.67 yards of ribbon.
Step-by-step explanation:
We know that each roll has 20 yd.
She used 3 + 1/2 rolls, then the total length used will be (3 + 1/2) times the length of each roll, this is:
(3 + 1/2)*20 yd = (6/2 + 1/2)*20yd = (7/2)*20yd = 70 yd.
With tose 70 yards of ribbon, she made 15 bows, then the length of ribbon used in each bow will be equal to the quotient between the total length used and the number of ribbons made with it, this is:
70yd/15 = 4.67 yards
Each bow needs 4.67 yards of ribbon.
