The truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
When discriminant D of a quadratic equation,
D = 0
Roots are equal and real
D > 0
Roots are real and different
D < 0
Roots have not existed.
When the discriminant is zero, there is only one real root to the quadratic equation. In other words, only the vertex of the parabola connects the x-axis. The vertex is the parabola's base.
Therefore, the truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

Answer:
b is the lowest and d is the highest y axis
Step-by-step explanation:
What is an equation of the line that passes through the point (-6, -7) and is
perpendicular to the line 6x + 5y = 30?
Answer:
Step-by-step explanation:
Product of slope of perpendicular lines = -1
6x + 5y = 30
Write this equation in y = mx + b form
5y = -6x + 30
y = [tex]\frac{-6}{5}x+\frac{30}{5}[/tex]
[tex]y=\frac{-6}{5}x + 6[/tex]
Slope of this line m₁ = -6/5
m₁ * m₂ = -1
m₂ = -1÷m₁ = -1 * [tex]\frac{5}{-6}[/tex]
[tex]m_{2}=\frac{5}{6}[/tex] & (-6 , -7)
Equation of the required line: y - y₁ = m (x - x₁)
[tex]y - (-7) = \frac{5}{6}(x - [-6])\\\\y + 7 = \frac{5}{6}x + 6 *\frac{5}{6}\\\\y = \frac{5}{6}x +5-7\\\\y=\frac{5}{6}x-2[/tex]

A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be made measures The longest side of the drawing measures The longest side of the actual triangular piece to be sculpted must be long. How long will the shortest side of this piece be?
Answer:
3.71 m
Step-by-step explanation:
Here is the complete question.
A sculptor is designing her new triangular masterpiece. In her scale drawing, the shortest side of the triangular piece to be made measures 7 cm. The longest side of the drawing measures 20 cm. The longest side of the actual triangular piece to be sculpted must be 10.6 m long. How long will the shortest side of this piece be?
Solution
This is a scale drawing question.
Since scale = Scaled size/Actual size, we need to find the scale ratio of the triangle.
Now, the longest side of the drawing measures 20 cm which is equal to the scaled size and the longest side of the actual triangular piece to be sculpted is 10.6 m long which is the actual size.
So, scale = 20 cm/10.6 m
= 0.2/10.6
= 1/53.
Since in the scale drawing, the shortest side of the triangular piece to be made measures 7 cm, this is the scaled size, so the actual size of the shortest side is gotten from
scale = Scaled size/Actual size.
So,
Actual size = Scaled size/scale
= 7 cm ÷ 1/53
= 53 ×7 cm
= 371 cm
= 3.71 m
The curved surface area of a right circular cylinder of height14 cm is 88 cm2. Find the diameter of the base of the cylinder.
Answer:
4
Step-by-step explanation:
The formulae for Curved surface
area = πrh
Area = 88cm2
height = 14cm
radius = ?
Let π be 22/7
88 = 22/7 x r x 14
cross multiply
88 x 7 = 22 x 14 x r
616 = 308r
Divide both sides by 308
r = 2
Diameter = Radius x 2
so our radius is 2, 2 x 2 = 4

Katarina wrote the standard form of a linear equation as 4x – 4 x minus StartFraction 2 Over 3 EndFraction y equals 8.Y = 8. Sofiya told her that the equation was not yet in standard form and gave her the right advice for how to fix it. What advice did Sofiya give to Katarina? Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12. Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 8. Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 4.
Answer:
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
Step-by-step explanation:
Katarina's equation
4x - 2/3y = 8
In order to convert Katrina's linear equation into standard form,
She should find the least common denominator
4x - 2/3y = 8
{4x(3) - 2y(1)} / 3 = 8
(12x - 2y) / 3 = 8
Multiply both sides by 3
(12x - 2y) / 3 × 3 = 8 × 3
12x - 2y = 24
Divide both sides by 2
(12x - 2y) / 2 = 24 / 2
6x - y = 12
The advice sofiya gave Katrina is to Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
Answer:
B) Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.

forever. If the required return on this stock is 7.78 percent, what is the current share
price?
Given :
Apocalyptica Corp. pays a constant $18 dividend on its stock.
The company will maintain this dividend for the next 4 years and will then cease paying dividends forever.
To Find :
If the required return on this stock is 7.78 percent, what is the current share
price.
Solution :
Current price ( After 4 hours ) :
[tex]C.P = 18[\dfrac{1}{(1+0.10)^1}+\dfrac{1}{(1+0.10)^2}+\dfrac{1}{(1+0.10)^3}+\dfrac{1}{(1+0.10)^4}]\\\\C.P=\$57.058[/tex]
Therefore, current share price is $57.058 .
Hence, this is the required solution.

Answer: AAS
Step-by-step explanation:
Lets call the intersection point between AC and DE F.
I think he meant the two triangles AFE and DFC.
We know angle A is congruent to angle D.
We also know AE is congruent to DC.
There is also a hidden piece of evidence which is AFE is congruent to DFC due to vertical angles.
We know two angles and 1 side, so we can use AAS to figure out that the two smaller triangles are congruent.

10. Points D, E, and F are non-collinear. How many lines can be drawn that pass through F and are perpendicular
to DE ? Use a diagram to illustrate your answer.
Given:
Points D, E, and F are non-collinear.
To find:
Number of lines that pass through F and are perpendicular to DE.
Solution:
Points D, E, and F are non-collinear. It means points D, E and F are not lie on a single straight line.
We know that, the number of perpendicular lines on a line from a particular point is 1.
So, number of lines that pass through F and are perpendicular to DE is 1 as shown in the below figure.

7/8 square foot in 1/4 hour
Answer:
2 1/2
Step-by-step explanation:
The unit rate for the given parameters is 3 1/2 square feet /hour.
Given that, 7/8 square feet in 1/4 hour.
We need to find the unit rate.
How to find unit rate?In a unit rate, the denominator is always 1. So, to find the unit rate, divide the denominator with the numerator in a way that the denominator becomes 1.
Now, unit rate = 7/8 ÷ 1/4
=7/8 × 4 =7/2
=3 1/2 square feet /hour
Therefore, the unit rate for the given parameters is 3 1/2 square feet /hour.
