Using the graph, determine the coordinates of the roots of the parabola.
I really don't understand how to do this because I have never been taught this before. Could someone help me out?
Answers
Answer: (-6,0) and (-8,0)
!!!!!!Also it's fixed now so ignore my comment about this being wrong!!!!!!
Step-by-step explanation:
To find roots you're basically looking for the points on the graph where they touch the x axis. Those are your roots. You can also plug 0 and -0 in for x and find the coordinates that way with the equation.
Answer:
Two points.
(-8, 0) and (-6, 0)
Step-by-step explanation:
The roots of a graph are another word for the zeros of a graph. In other words, the roots or zeros of a graph are whenever the graph touches or crosses the x-axis. Another way to think about roots are that the roots of a graph are simply its x-intercepts.
From the graph, we can see that it does this twice: once at [tex]x=-8[/tex] and again at [tex]x=-6[/tex]. At both of these points, the graph crosses the x-axis.
Therefore, we will have two roots in this case: one at (-8, 0) and another one at (-6, 0).
So, our answer is two points, being: (-8, 0) and (-6, 0).
And we're done!

The area of a square shaped yard is 201.5 ft2. Which measurement is closest to the side length of this yard in feet?
Answers
Answer:
a = 14.19 feet
Step-by-step explanation:
Given that,
The area of a square shaped yard is 201.5 ft²
We need to find the side length of this yard in feet.
The area of a square shaped object is given by :
A = a², a is the side length of the object
Put A = 201.5 ft² in above formula,
[tex]201.5=a^2\\\\a=\sqrt{201.5 } \\\\a=14.19\ \text{feet}[/tex]
So, the side of the square yard is 14.19 feet.

The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.
What are Congruent Triangles?There are criteria that can be used to show that two triangles are congruent to each other. They are:
ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.
The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.
The answer is, C. Might not be congruent.

1. How many pounds of Brazilian Coffee should be mixed with 6 pounds of Colombian Coffee to get
mixture?
Answers
Answer:
12 pounds
Step-by-step explanation:
Colombian Coffee sells for $9.25 per pound. Brazilian Coffee sells for $7.75 per pound.
The management wishes to mix 6 pounds of Colombian Coffee with an amount of Brazilian Coffee so that the mixture sells for $8.25 per pound.
Hence:
Let the number of pounds of Brazilian coffee be represented by = a
$9.25× 6 + $7.75 × a= $8.25 (a + 6)
55.5 + 7.75a = 8.25a + 49.5
Collect like terms
8.25a - 7.75a = 55.5 - 49.5
0.5a = 6
a = 6/0.5
a = 12 pounds
Therefore, 12 pounds of Brazilian Coffee should be mixed with 6 pounds of Columbian nuts

6=1/12v solve each equation. Check your solution
Answers
Answer:
112v=6 1 12 v = 6 . 12
Step-by-step explanation:
The solution to the equation is v = 72.
We have,
To solve the equation 6 = (1/12)v, we can follow these steps:
Multiply both sides of the equation by 12 to eliminate the fraction:
6 * 12 = (1/12)v * 12,
72 = v.
Therefore, the solution to the equation 6 = (1/12)v is v = 72.
To check this solution, we substitute v = 72 back into the original equation:
6 = (1/12)(72),
6 = 6.
Since both sides of the equation are equal, we can confirm that the solution v = 72 is correct.
Thus,
The solution to the equation is v = 72.

Answers
Answer:
Equilibrium quantity before the tax = 40 units
Step-by-step explanation:
Given:
Qd = 240 - 5P
Qs = P
Computation:
Qd = 240 - 5P
P = 48 + Qd/5
Equilibrium quantity before the tax
Qd = 240 - 5P
P = 240 - 5P
